A Close-up View Of Disc Brakes Brake Pads: Worn pads can groove rotors, causing brake noise and damage. Excessively worn pads should be replaced. Calipers: Calipers hold pads in place against the revolving rotor to stop the vehicle. Leaking calipers can damage pads and weaken the system, causing unreliable stopping. Damaged calipers should be serviced or replaced. Rotor (or Disc): The disc pads make frictional contact with the rotor to stop the vehicle. Warped or grooved rotors wear out pads fast, cause brake noise and dangerous brake lock-up, and should be resurfaced or replaced. Grease Seal: This seal protects wheel bearings from foreign materials and prevents lubricant leakage. Damaged seals will cause excessive wheel bearing wear and should be replaced. Caliper Seal: This seal returns pistons to neutral position, prevents brake fluid leakage, and helps maintain piston adjustment. Damaged seals hamper piston operation. Pads remain against rotor, causing excessive pad wear, heat damage to rotor and pads, and low gas mileage from brake drag. Damaged seals require caliper service. Caliper Piston: This piston pushes against the pads. A damaged piston may freeze, causing brake drag, excessive pedal effort, pad wear, or leakage. It should be replaced and the caliper should be serviced. Dust Boot: The Dust Boot protects the caliper seal, caliper piston slide surface, and internal caliper parts. If damaged, excessive caliper-seal wear results, causing fluid leakage and damaging delicate internal parts. Damaged dust boots require caliper service. Caliper Hardware: These keep the caliper in place and retract the caliper. Damaged hardware cause excessive pad wear, dragging and brake noise, and should be replaced. |
