What it does
Brake parts are usually replaced per axle, left and right together, so the car stops straight. Brakes are the most important safety system on the car; replacing worn parts restores stopping power and pedal feel, and upgraded parts handle heat better.
Installation & tips
- Bed in new pads and rotors following the brand instructions, and bleed the brakes if the system was opened.
- Brake fluid: Old fluid absorbs water; flush it when you do a brake job.
- Hardware: Clips and pins wear with the pads.
- This part affects how the vehicle stops, steers or holds the road. If you are not sure how to fit it, have it installed or checked by a qualified mechanic.
