    • Warped brake rotors. This is the number-one braking myth. Perhaps it has become so ubiquitous because, at first, it appears to make sense. If you feel steering wheel vibrations or pedal pulsations when braking, then the disc’s surface must be uneven because it is “warped” from excessive temperatures, right?
    • Bigger brakes will help you stop quicker. Brake rotors with a larger radius will increase the lever arm of the braking force over the center of the hub and, therefore, the braking torque applied to the wheel.
    • Drilled or slotted brake rotors are better. We’ve already seen that fitting bigger rotors does not necessarily make sense for a normal street-driven vehicle.
    • Disc brakes stop faster than drum brakes. Fewer and fewer cars nowadays use drum brakes and those that do only use them on the rear wheels, where the braking forces are lower.
  1. Jul 10, 2024 · July 10, 2024. Few topics generate as much debate and misinformation as brake rotors and their propensity to warp. Among the most persistent myths is the belief that brake rotors warp due to excessive heat. This misconception has been perpetuated for years, leading to unnecessary repairs and replacements, costing car owners time and money.

  2. Jan 3, 2024 · Potential for Brake Failure: In extreme cases, overheated brakes can fail completely, posing a significant safety risk. Damage to Brake Components. Warped Rotors: Excessive heat can cause brake rotors to warp, leading to uneven braking and vibrations. Degraded Brake Fluid: High temperatures can also break down brake fluid, affecting its ability ...

  3. Soft or Spongy Brake Pedal. A common symptom of overheated brakes is a soft or spongy feeling when pressing down on the brake pedal. This is caused by the water vapor that collects in the brake fluid reservoir turning into steam as the brake fluid heats up. This can lead to excessive heat building up that can reduce the performance of the brakes.

    Depending on the type of rim your vehicle has, chances are you can see them when your car is parked. If you see what looks like a large metal plate, platter or disc, that part is the brake rotor. The brake pads on your car press against the brake rotor, sometimes called the brake disc, to stop the car. Depending on your year and model, you might ha...

    As you can imagine, rotors are a vital part of your vehicle’s braking system. Every bit as important as the brake pads. Brake rotors need replacing for several reasons, including: 1. They are too thin. Over time, the rotors do wear down. When they get to be a certain thinness, they will need replacing. 2. If the brake pads become very worn, the met...

    Even when you replace the brake pads promptly, everyday wear and tear and heat can cause the rotors to become uneven. Your mechanic will remove the rotors and put them on a machine called a lathe. The lathe will remove a very small amount of metal from the rotor, making it as smooth as the day your car came new from the factory. This is called mach...

    For many reasons, some people simply don’t want to replace brake rotors when they are too thin. They may even have a mechanic just install new brake pads because the “rotors look fine.” Driving with brake rotors that are extremely worn will not only make noise, cause the brake pedal or steering wheel to feel strange, but they also create a dangerou...

    Most cars give you warning signs that the brake system needs to be looked at. Some important things you might notice when the brake pads or rotors need replacing include: 1. Pulling to one side when braking 2. A vibration in the steering wheel 3. Brake fade (This is when you step on the brakes but the pedal sinks to the floor or the car takes a lon...

    You want to keep safety in mind whenever it comes to repairing your vehicle. Brakes play a huge part in the overall safety of you, your passengers, and everyone else on the road. Don’t play games when you notice a problem or a noisecoming from your brakes. You can trust the ASE certified mechanics at My Mechanic to do a complete inspection and repa...

  4. High temperatures can cause the brake fluid to boil, creating air bubbles in the brake lines. This reduces the fluid’s ability to transfer force, leading to brake failure. Maintaining proper brake fluid levels and considering using high-temperature resistant fluids to ensure your brakes function correctly even in hot weather is essential.

  6. Oct 4, 2024 · Brake rotors are an essential part of a vehicle’s braking system. They work in conjunction with the brake pads to provide the necessary friction required to slow down or stop the vehicle. However, excessive heat can cause various issues with the brake rotors, leading to potential safety concerns.
