- 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.
Jun 18, 2022 · Shops usually quote about 2 hours of labor for turning brake rotors. This includes placing the vehicle on a lift, removing the wheels, and unbolting the brake calipers to free the rotors. Depending on the shop, rotors might be turned on a bench or by using an on-car brake lathe.

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...
Aug 28, 2024 · Turning brake rotors is a term that is used to describe machining, or lathing, brake rotors down to remove the excess brake material from your pads and to prevent warping and grinding, thus extending the life of your brake pads. Turning a rotor allows for smooth braking action and creates less heat then those that are warped.
Jun 23, 2023 · Purpose of Turning Brake Rotors. Turning brake rotors means resurfacing the braking surface of the rotor. This is done with a brake lathe to remove any imperfections or wear. It helps restore smoothness and parallelism, which boosts performance and extends the rotor’s lifespan. Friction during braking generates heat.
Jan 4, 2016 · 1. Noisy Brakes. One of the first symptoms commonly associated with bad brake rotors is noise. If the rotors are warped (meaning not perfectly flat) or severely worn, they may produce squealing or squeaking sounds. Usually, warped rotors will produce a squeak, while severely worn rotors will produce a scraping sound.

What is a brake rotor?
Brake rotors work with the brake pads to safely stop your car every time you hit the brake pedal. The rotor rotates with the wheel and when you apply the brake pedal, the brake pad clamps down on the rotor to bring your vehicle to a stop. When it comes to stopping your vehicle, rotors are as important as the brake pads.
