The main components of how to replace disc brake are:
The brake pads
The caliper, which contains a piston
The rotor, which is mounted to the hub
• Using a lug wrench, crack the wheel lugs loose one or two turns. Do not remove them completely.
• Jack one side of the vehicle up and support it with a jack stand. Do the same for the opposite side.
• Remove the lugs and take the wheels off.
Remove the calipers:
• Remove the two caliper guide pins or bolts. Look at the locations and positions of any bushings or guides so they can be reinstalled properly.
• Rock the caliper back and forth to push the piston back enough to slide the caliper off.
• Remove the caliper. Use a large C-clamp and push on the inboard pad to move the piston back into the caliper. Do it slow and steady.
What you will need:
Screwdriver or pry bar
Pliers or vise grips
New brake pads
Never work on a vehicle that is only supported by a jack. Use jack stands to support the vehicle while you work. Work on a solid, level surface. Never jack a car up on dirt or grass.
Do one wheel at a time so you can use the other wheel as a reference in case you get confused.
Check for any fluid leaks or cracked brake lines. Replace them as necessary.
Brake linings contain asbestos. Avoid creating or breathing dust when changing linings or cleaning parts.
• Remove the pads from the calipers
• Check the rotor for scores, rusting or pitting. It is recommended that the rotors be resurfaced to remove any imperfections and true up the braking surface to prevent brake pulsations.
• Clean the caliper mounting surfaces with a wire brush and remove all the rust and dirt. The sliding surfaces must be as clean as possible for proper brake operation.
• Install the new brake pads in the reverse order of removal. Make sure any shims, clips and anti-rattle springs are in place. Some brake pads have ears that need to be crimped to the caliper when installed. You can use a large pair of Channel locks or a hammer to crimp the ears.
• Replace the caliper on its mount and reinstall the guide pins, retainers or clips that you have removed. Some retaining keys need to be tapped back into place with a hammer.
• Tighten all bolts being careful not to over tighten.
• Fill the master cylinder with new brake fluid from a sealed container and bleed the brakes if required.
