Brake Rotors: what it does & when to replace it
Brake rotors (discs) are the metal discs the pads clamp onto. They wear thinner over time and can warp from heat. Replacement signs include a pulsation or shudder through the brake pedal or steering wheel under braking, deep scoring or grooves you can feel, a blue tint from overheating, or rotor thickness below the manufacturer minimum stamped on the hub. Rotors are usually replaced in pairs (both sides of an axle) and most shops now replace rather than machine them. Replacing rotors is a moderate DIY job and is commonly done together with new pads.
DIY difficulty: Moderate DIY (replace in pairs, do with pads). Always confirm the correct part for your exact build by VIN before buying.
