Critical Brakes
Brake Disc and Caliper Wear
Symptoms
Pulsing brake pedal, pulling to one side under braking, squealing or grinding noises, seized caliper pistons.
Cause
Brake discs wear and warp with use. Caliper pistons seize if not exercised regularly or if moisture contaminates the fluid. Pad material hardens with age.
Fix
Replace discs and pads as a set.
If a caliper is seized, rebuild it (new seals, pistons, dust boots) or replace it.
Clean and lubricate the slider pins.
Bleed the brakes and check for leaks.
Ensure the handbrake mechanism is free and adjusted correctly.
