Do you need new rotors with new brake pads?
Some vehicles always require new pads and rotors because the rotors cannot be resurfaced. But for optimum brake performance and safety, always choose to replace your brake rotors when replacing your brake pads.
Why are my brakes still scraping after new pads?
Another reason why your car may be grinding is that there is debris on your brake pad or rotor. If a mechanic sees debris on the rotor when they are replacing the pads, they should clean it or repair it. But often, dirt or dust sneaks on between the pad and rotor when the new pad is being installed.
Can I put new brake pads on a damaged rotor?
DON’T REPLACE BRAKE PADS ON DAMAGED ROTORS Your brakes rely on friction from the brake pad as it is pressed against the rotor to help stop the car. If new brake pads are put onto a vehicle with damaged rotors, the pad will not properly contact the rotor surface which will reduce the vehicle’s stopping ability.
How should brakes feel after being replaced?
Brakes are self-adjusted so you should never feel any difference (except for that first pump after the change). The range of travel should be the same with a brand new pad versus one that is complete worn, since the brake cylinders don’t retract back to a fixed position.
Why are my new rotors scraping?
Possible causes include the backing plate, which is located behind the brake rotor and can get bent and rub on the rotor. This is a simple fix: the technician will just bend it back in place. Also, brake pads have metal shims between the back of the pad and the caliper piston that can come loose and scrape the rotor.
What makes up the front and rear brake rotors?
On most modern car designs, the front and rear brakes are made up of multiple parts: a rotor and a pad. The rotors are circular discs connected to each wheel. They are designed to convert kinetic energy from the turning motion into thermal energy.
Why are the rotors on my disc brakes Warped?
The friction between the pads and rotors converts rotational energy into heat, bringing your vehicle to a stop. This friction warps the rotors over time. Warped rotors provide less consistent contact between your pads and the discs, which means less consistent braking for you.
Do you need to change your brake rotors?
Whether you’re looking to replace your stock quality rotors, or you want to boost your brake system’s power, AutoZone has all the parts you need to do-it-yourself and save on your brake rotor replacement cost. If you’ve never changed rotors before, check out our DIY brake job guide.
What happens when you press on the brake rotor?
The pad tightens on the rotor when you press on the brake pedal. Pressure is subsequently exerted on the fluid in the master cylinder, which activates the caliper housing in both pads. The result is friction, which transforms the forward momentum of the vehicle into heat.
