Disc Brake Inspection
Disc brake pad service starts with a thorough inspection. And like most inspections, it should include a thorough visual inspection. The visual inspection should include the following:
The brake caliper and caliper mounting for loose or damaged parts. Make sure the caliper and anchor bracket attaching bolts are tightened to the specified torque.
Ensure the caliper mounting surface is clean and free of nicks or burrs. Check the brake lines, hoses, and fittings for leaks or damage. Look closely for wet areas that might indicate a leaking seal.
Measure the rotors for thickness, disc thickness variation, and runout carefully.
Check for even brake pad wear from side to side. If the set of brake pads on one side of the vehicle is exces sively worn, it may indicate a piston which is seized in the caliper bore, or excessive corrosion on the caliper pins or slides.
