How to Measure Brake Rotors

How to Measure Brake Rotors

When considering brake repair, rotor thickness is as important an aspect to check as checking the brake pads. A brake rotors must have enough rotor material to absorb and disperse heat, while at the same time, maintaining its structural integrity. Brake rotors that have a thickness below minimum specifications are at a high risk for fade and cracking. Most rotors have a minimum thickness noted either on the casting of the rotor or in the factory service manual for your vehicle model, so it’s important to accurately check actual thickness to ensure it is above these specifications.

When to Check

Thickness should be checked whenever brake pads are replaced, and before any resurfacing work is done. Mostly you can count on your auto  repair shop to check the brake rotors when ever servicing the braking system. This is to ensure that the rotors have sufficient material to be put back into service. It is a good practice to do this every time the brake pads are replaced, regardless of the interval between changes. It only takes about 5 minutes or less and is a good safety measure to be in the habit of.

How to Check

If you are into doing this yourself, instead of hiring a auto repair shop, most factory service manuals are very specific about testing procedures. Using a micrometer, rotor thickness should be measured in eight to ten places, approximately 45’ apart and 10mm from the edge of the rotor. These readings should all be above the minimum specifications for thickness, and should vary by no more than the maximum brake values listed in the manual. This will help ensure smooth and consistent braking performance.

Picture of Micrometer

Making sure your brake rotors thickness is above the minimum listed values found either on the casting or in your car’s service or owner’s manual is an important step in brake repair. Proper measurement only takes about 5 minutes and any brake repair shop will be happy to include this service. Brakes in the car are one of the most important elements in driving; don’t take their health for granted ever.

Cars Braking System & How It Works

Cars Braking System & How It Works

The basic idea of the cars braking system is relatively simple. However, as illuminated by the hundreds of individual parts for sale at your local auto parts shops, it actually takes a lot of technological apparatus to make cars work. When it comes to your car’s safety, brakes top the list of systems that need monitoring. Here are some simple starter tips on how your braking system works.

How Brakes Work

A car’s brakes are probably the most critical system on the vehicle. If they go out, you have a big problem. Thanks to the mechanical operating system of leverage, hydraulics and friction, braking systems provide unconceivable stopping power. So, what happens after you push the brake pedal?

How Disc Brakes Work

Disc brakes are the most common braking system found on a car’s front wheels, and they’re often on all four. This is the part of the brake system, which does the actual work of stopping the car. Your auto repair mechanic can tell you more about disc brakes and when to have the brake pads changed.

How Anti-Lock Brakes Work

Stopping a car in a hurry on a slippery road can be challenging at best and very, very scary at worst. Anti-lock braking systems (ABS) help alleviate the danger. The anti lock braking system is mainly designed for a safe and comfortable ride. A wheel, which is skidding, has less traction on the road than a wheel, which is not skidding. On wet roads, the wheels are going to get very little traction when the brakes are applied. The ABS avoids wheels from locking when braked, letting them rotate at a lower speed, thereby preventing the car from skidding.

How Power Brakes Work

Power brakes are inspired machines — they let you stop a car with a simple shudder of your foot. The concept at the heart of the power braking system is force multiplication. A whole bunch of force multiplication. This system uses the power of engine and battery to increase the efficiency of braking system. If you’ve ever opened the hood of

your car, you’ve probably seen the brake booster. It’s the round, black canister located at the back of the engine compartment on the driver’s side of the car. The brake booster uses vacuum from the engine to multiply the force that your foot applies to the master cylinder.

How Master Cylinders and Combination Valves Work

We all know that pushing down on the brake pedal slows a car to a stop. We depend on that every day when we drive. How does this happen? The master cylinder supplies pressure to both circuits of the car. It is a remarkable device that uses two pistons in the same cylinder in a way that makes the cylinder relatively failsafe. The combination valve warns the driver if there is a problem with the brake system, it also does a few more things to make your car safer to drive. Your mechanic can demonstrate the full scope of your braking system if you want to learn more.

There you have it, your cars braking system explained in a nutshell. Was this article helpful?

The Different Levels of Brake Repair

The Different Levels of Brake Repair

Brake repair cost will vary depending on what needs to be done to get you back on the road and driving safely. Most auto repair shops such as will perform a free basic brake check to determine the extent of any problems. If you hear any brake noise such as screeching, squeaking or grinding, you should immediately have your brakes checked.

Brake Problems

There are several things that can go wrong with brakes. Worn out brake pads, calipers and drums might be the issue, but it could also be a problem with your master cylinder, individual wheel cylinders or simply a lack of fluid. The cost of repairing brake problems truly depends on what is wrong.

Low Fluid

The easiest of brake repair problems simply involves a low amount of brake fluid in the master cylinder. Removing the cap and topping off the fluid is the way to fix it, but keep in mind, if the master cylinder is empty, pouring more fluid in will push air into the system. To fix this you will have to bleed the brakes, If you are like most, you can’t do this yourself, it will cost some labor hours with a certified brake repair mechanic.

Worn Pads or Drums

A standard brake problem is worn pads and drums. Because brakes use friction to stop the car, as time wears on, so do the brake pads. It’s just a simple fact of physics. Friction causes wear. After a while, brake pads must be replaced. You will detect a need to replace pads by hearing gradually increasing squeaking whenever you hit the brakes. If it goes on too long without being replaced, eventually you may have to replace the drums and/or rotors as well. At this point, what could have been a relatively inexpensive fix is now more expensive. A standard replacement of pads and servicing the rotors may cost $175 to $195, whereas a drum, rotor, and/or caliper replacement can get up into the several hundred depending on the extent of the problem.

Master Cylinder and Wheel Cylinders

The master cylinder is where the brake fluid is stored and through compression, is then sent to each wheel cylinder. This fluid is what applies force to the pads and drums when you press down on the brake pedal. If the master cylinder goes bad, when you press down on the brake pedal, it might go to the floor and take longer to stop the car. At best, your braking power is greatly reduced; at worst, it could endanger your life and others by not stopping the car at all. The average cost of master cylinder repair is usually between $200 and $300, but it can be more, again, depending on the scope of the fix. If individual wheel cylinders need to be replaced the cost goes up.

The repair price for an entire brake job—rotors, calipers, drums, pads, cylinders—can run you $750 or more. Therefore, it’s best to stay on top of brake repair and get the pads replaced when you hear squeaking. Components like master cylinders wear down after time, so eventually it will have to be replaced. As long as you keep brake fluid in it and keep an eye on it, though, you’ll be safe to drive and can take the steps to have your brakes repaired when it comes time.

Braking System Failures and How to Avoid Them

 Braking System Failures and How to Avoid Them

For those who endure a daily commute through heavy traffic, your vehicle’s braking system can bring thousands of pounds of metal and plastic to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice that your cars braking system needs attention until it’s too late.

Neglecting your braking system can lead to increased repair costs, or worse, no brakes at all. Fortunately, paying attention to some of the signs of brake wearcan keep you on top of the cost of maintenance, saving you some money and keeping your car from getting up close and personal with the car in front of you.

The most obvious indicator that your vehicle’s brakes need attention is an incredibly high pitched squeal when you come to a stop. Brake pad manufacturers include a little piece of metal called an indicator on the pad itself. When the material wears down to the point where less than ¼ inch is left, the metal piece begins to touch the vehicle’s rotor, doing a pretty good impression of fingernails on a chalkboard. Depending on how hard you drive, that usually means you should replace your brake pads within the month.

Occasionally, the indicator rusts and falls off, leaving you with no irritating noise to warn of brake wear. Additionally, many aftermarket and low-cost pads don’t come with a wear indicator at all. For the more observant, there are other signs that your brakes need attention. If it takes you longer to stop than it used to, or if your brake pedal travels farther than it did a few months ago, it might be a good idea to get your brakes checked. Regular brake pad checks are a good idea and require little more than removing a wheel and knowing what to look for.

Brake rotors are a little trickier, as they can usually last through two or three sets of brake pads before needing to be replaced. If your steering wheel wiggles in your hands when you come to a stop, your brake rotors are probably “warped,” and it’s a good idea to swap them out.

Your mechanic might offer to “turn” your brake rotors for you instead of outright replacing them, if it’s an option. This means shaving enough metal off of the rotors to make them smooth again. Newer vehicles are equipped with thinner, lighter rotors to save on costs and increase fuel economy. If you’ve got the option, go ahead and replace them.

There are several options for replacement brake parts for your vehicle. While you can never go wrong with what your manufacturer recommends, a variety of aftermarket parts can help you match your brake system to your driving style. If you find yourself replacing brake rotors often, you might consider switching to a slotted version. While initially more expensive, the slots disperse heat better than stock, though 99 percent of the time they aren’t necessary for the average driver.

Your brake rotors aren’t the only piece of braking system hardware that can be changed for better performance. One of the most common brake pad upgrades is a switch to ceramic pads. These pads stop just as well, if not better than the stock pieces, but produce much less dust and are generally quieter. While you can also install performance brake pads on your vehicle, these usually have a shorter life span and generate more wear on your rotors.

While neglecting your brakes until your car is grinding to a halt instead of gliding is always an option, it can cost you in unnecessary rotor replacement and possible towing bills. That’s not to mention the likelihood of losing most of your stopping ability right when you need it most. Keeping up on your braking system maintenance, paying attention to the signs of brake wear and choosing the right equipment for your vehicle will let you slow down like you should… When you need to!

What You Must Know About Having Your Brakes Repaired in Venice, FL

Hello again. Dallas Council back with you from AAMCO Transmissions of Venice and today, I want to talk about a very common question that we get, a question that you at some point may have asked and that is, “Can’t you buy us a cheaper part to make our repairs less expensive?”

The answer to that question is inevitably yes. You can always find someone willing to sell you a lesser quality part that will ultimately make your repairs less expensive but a big part of our mission statement here at AAMCO Transmissions of Venice says that we will never allow our customers to talk us into a lesser quality repair than is absolutely necessary to meet their needs.

So with that said, today, I want to discuss the difference between a few different qualities of brake parts as pertaining to your braking system.

So first up, what I’m going to show you is just the very lower level Duralast Brake Pad. This is a pad that is made of an organic material. As you will see, nothing very special about it. The big problem with these pads, they are very susceptible to buildup of heat, which in turn will warp your rotors, make excessive brake noise and cause excessive brake dust. So, definitely not a good pad. We do not recommend these to our customers nor do we install them here at our shop.

Second up is the Duralast Gold Pad. These are a semi-metallic pad. You will notice that they have customized shims on the back from 3M which just adds some quality. We install these brake pads on 80 percent of the vehicles that come to our shop. These pads retail for somewhere in the $60 range. The pads that I just showed you previously, the lower levels, retail for somewhere in the $40 range. So for a $20 difference, the quality and durability that you get with these Duralast Golds are an exceptional value. Again, we install these pads on 80, 85 percent of the vehicles that come to our shop.

Next up is the highest level that they offer. These are the Duralast Gold CMax. The big difference between these and the regular Golds is these are fully ceramic pads which is about the best that you can buy and then the shims on the back are customized rubber material. It helps cut down drastically on vibrations. It also saves on brake noise.

One other big difference is, the Duralast CMax will also come with the hardware clips for the front brakes. Not always is it necessary to replace these. Normally on heavier duty applications, we recommend them the CMax pads unless we have a specific request or want to meet a specific need for our customers. These pads retail for somewhere in the $80 to $90 range. Again, all the prices can vary and depend on applications.

So lastly, I just want to talk about the brake rotor. This is the part that your brake pad compresses onto to stop a vehicle from moving. It is not always necessary to replace the brake rotor. You always want to at minimum have the brake rotor serviced. At some point, you will have to replace them or if they are warped or beyond being serviced, you will have to replace them.

Brake rotors can retail anywhere from $40 to as high as $120, some maybe more depending on application. It is something that you do not want to leave unattended. You never ever want to put pads on without a bare minimum service in the rotor.

So keep all these in mind. I know everyone is very price conscious. It is much better to get the most value for your money. Again, you can save 20 bucks on your brakes and in another 30,000 miles you really haven’t saved anything but it has actually cost you more money, not to mention the safety concerns involved.

So again, Dallas Council from AAMCO Transmissions of Venice. Thank you very much for joining us. If you enjoyed this video, please leave some comments or if you have ideas or suggestions of videos that you would like to see from us in the future, leave those in the comment section too. We love to produce any video that you may have an interest in. Again, thanks and have a great day

Brakes, and Common Symptoms of Failure!

Brakes, and Common Symptoms of Failure!

Braking systems for automobiles are engineered so that the various components work in concert to provide a consistent braking performance. Many anti-lock brakes are also equipped with a system for alerting the vehicle’s operator when the brakes are in need of repair or replacement. Squeaking brakes can be a sign of one or more of the components being in disrepair. At the first audible alert from your brakes, inspect the system to determine the necessary repairs.
If your brakes are squeaking, don’t panic. Often squeaking can start for harmless reasons. Temporary moisture from outside can get in the brake pad and cause a squeaking noise, but this is different from a continuous wail. If your brakes are grinding or squeaking constantly, it means your pads have worn down significantly and need replacing.

In the old days, brake pads were made of asbestos, which, a few years ago, was outlawed by the federal government. Most brake pads now are made of hard, semi-metallic materials. One result is that brake squeal has become common, as the hard brake pad grinds on the steel rotor. This is normal and is not necessarily an indication of brake failure. A brake inspection is the only way to find out for sure. Listen to your car braking system with a discerning ear.

  • A Vibration in the brake pedal, steering wheel or your seat when applying the braking system indicate warped rotor(s) or a problem with some loose front end parts.
  • Red Brake Indicator Light – could be low fluid, contaminated fluid, or possibly your parking brake is on or the switch is stuck.
  • Yellow ABS indicator light indicates a problem somewhere in the ABS system. Though your braking system should work in its proper manner, it is suggested that an brake system inspection should occur immediately.
  • Hard Brake Pedal – can be caused by power brake failure, a hydraulic wheel cylinder, poor brake pads or shoes or even a stuck brake caliper.
  • Low Brake Pedal – could be caused by low brake pads or shoes. It may be something as simple as a braking system adjustment and will usually accompany the Red Brake Indicator Light.
  • Grabbing Brakes – might be contaminated brake pads or shoes, or a loose or broken front end component ready to give way.

Remember, the braking system is not to be ignored, if you do have brake issues, make sure that you have a mechanic take a look at it. Only someone who knows what they are doing should attempt repairs to the brake system.
