Factors That Affect Brake Rotor Performance

Numerous parts all work together that allow you to stop on a dime when need be or slowly come to a stop when at a traffic light. Calipers, master cylinder, brake pads, and arguably one of the most essential, rotors all need to work together for the best possible braking power. The braking system of your BMW can be complicated if you don’t know what you are looking at.

A rotor is the part of your braking system that the pads squeeze against allowing your vehicle to come to a stop. A wonderful thing about these parts is they can last a long time, in most cases, before needing to be changed. However, when they do need to be replaced taking it in for auto repair BMW is the best way to ensure it is done correctly. Rotors are considered a main component, and if these fail or have an issue, it will negatively affect your ability to stop precisely. You may notice strange sounds when braking, no matter how light or firm you apply the brake.

The two most common problems that occur with the rotor include warping and uneven wear. The cause of these is almost certainly linked to worn out brake pads. Brake pads can wear unevenly, causing tension to be dispersed around the round inconsistently. What can happen here, is the front of the rotor will wear down faster than rear or vice versa, not allowing for even pressure. A sign this is already happening to your care is not stopping straight. If your car tends to pull to one side when coming to a stop, it might be a sign your rotors have uneven wear or damage already done to them. It could also signal that the material on the rotor has worn down, and the part needs to be replaced. Consider upgrading to drilled and slotted rotors for better performance as well as better cooling effects for less chance of warping, if your vehicle doesn’t already have this type installed.

How You Drive Plays a Role

Consider your driving technique. Do you like to ride the brake? Are you a fan of speeding up quickly only to hit the brake just as fast? How you drive will ultimately dictate how long a rotor and other braking components last. While for most adult drivers trying to change how you operate can be a challenge, it is one you should pay attention to. By modifying how you drive, or in this case stop, you can get more miles out of your pads and rotors. Instead of slamming on your brakes for each stop, start braking sooner. In doing so, your brake pads will slowly come in contact with the rotor. This action will keep your rotor in better shape for a more extended period of time.

Replace Pads When Needed

Most brake pads that come on BMW, Mini Cooper, Audis, and almost every vehicle now have an indicator on them. The indicator pin will sound like a high pitched screechy sound. Once you hear this noise, it means it is time to replace the pads for an automotive repair near me shop. Don’t delay. Putting off changing your brake pads will cause more wear on the rotor. Once you start hearing a lower pitched noise when coming to a stop, you have gone through the pads, and now the caliper may be contacting with the rotor. The low pitched noise or grinding sound makes scratches into the rotor making it virtually unusable when putting new pads on.

What Happens During A Brake Inspection?

Most car owners are aware of the role their brakes play in a vehicle. However, many are unaware of what components make up the braking system and what happens when they take their car in for an inspection. Before getting into what goes on during a brake inspection, it is essential to know what the brake system is made up of. Most BMW’s, especially newer models all utilize four-wheel disc brakes. Disc brakes offer better stopping power and are more reliable. The disc brake system includes brake pads, rotors, calipers, hoses, a master cylinder, and brake booster. The disc brake system is quite simple. When you press the brake pedal the two brake pads that side inside the caliper clamp against the rotor. The firmer you push the pedal, the harder they clasp.

Older model vehicles might be equipped with drum brakes on the rear. Drum brakes work similar to the disc brake system. However, they aren’t as reliable. They have a housing called the drum and use brake shoes that press against the drum to stop the vehicle. Since many cars are now equipped with the disc brake system, we’ll focus on what happens during a disc brake inspection.

Over time the parts of the brake system, specifically the brake pads, will wear down. Brake pads must be changed to prevent premature damage to the rotors or caliper malfunction. Many of the brake pads made today have a wear indicator installed. It alerts drivers that it is time for them to be changed. The wear indicator will make a high pitched squeak noise. Other parts of the brake system can give clues to problems they might have, which makes diagnosing the issue a little easy. For instance, if a caliper sticks it will make a bad burning smell and sometimes produce smoke because of the friction. If the brake pedal isn’t feeling as firm as it once was, this might indicate a lower level of brake fluid that needs to be filled.

Brake repair and service is very common in automotive shops. It is a service that has to be done for a vehicle to remain safe on the road. A brake inspection can be done at the shop of Ryan GMW – come, visit us at our repair shop! Curious about what happens during a brake inspection? Here is a list of components that are inspected to ensure everything is working correctly and if anything needs to be replaced.

  • Check brake pads for wear and access how much is left on the pads
  • Check rotors for even wear and warpage
  • Check brake fluid, fill if needed
  • Inspect brake lines

When a technician looks at your vehicle, they will probably inspect the brake fluid level first. Often many of the problems with brakes can be related to low brake fluid. Moving on from the master cylinder, its wheels will be taken off to inspect the workings of the disc brake system. It will include the brake pads, rotors, and calipers. A technician will determine how much of the brake pad is left and if the wear is normal. If something is wrong such as a warped rotor, stuck caliper, or uneven wear of the pads and rotors, they will let you know that those items need to be replaced.

Brake inspection is the first line of defense in keeping your vehicle’s stopping power at optimal performance.

If noises or changes in how your vehicle stops are noticed, it might be time to take it in for a brake inspection.

What Are The Causes Of Brake Failure?

In your vehicle, the brake pedal connects to the pistons, which connects to the brakes themselves. Most recent cars have disc front brakes and drum rear brakes. When your brakes function well, their primary purpose is to stop your vehicle through causing friction. In front brakes, friction will hold the brake calipers and pads. In rear brakes, the friction hits the brake drums and shoes.

What causes brake failure? Several factors interfere with the proper function of your vehicle’s brakes. Grease or oil on your brakes causes lead to failure. This oil will interfere with the friction of your brakes. This issue also means that your vehicle may have an oil leak.

In the warmer months, there is also the possibility of overheating. When brakes overheat to a moderate to a severe level, the metal in the brake rotors or drums will develop. This incident is what are known as hard stops. These are also called hot spots. Hot spots resist the friction from the brake shoes and pads. Because the shoes or pads cannot grab onto anything, there is no friction, and your brakes have failed.

If you tend to brake hard or ‘ride the brake’ as you drive, you can also cause brake failure in your vehicle. It also happens with those who are nervous drivers and are always braking due to their anxiety. These drivers cause premature brake failure due to an issue known as crystallized brake pads or shoes. Production of heat will then occur, caused by repeated overuse. After which, the pads and shoes grow hard. When they become hard, they are going to be ineffective because brake material must be flexible and able to grip the disc or drum to stop the vehicle.
