REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4, 5, 6 and 7
- Siphon 2 / 3 of the brake fluid out of the master cylinder.
- Raise and safely support the vehicle.
- Remove the tire and wheel assembly.
- If the caliper is to be completely removed from the vehicle for bench service, disconnect and cap the brake line from the caliper. Discard the old washers.
- Remove the caliper mounting bolts and sleeves.
- Remove the caliper from the knuckle.
If the caliper is tough to remove from the steering knuckle, compress the caliper piston back into the caliper bore using a large pair of pliers or a C-clamp.
- Remove the brake pads from the caliper, if it is being replaced.
- Install the brake pads in the caliper.
- Install the caliper on the steering knuckle.
- Install the mounting bolts and sleeves and tighten to 40 ft. lbs. (51 Nm).
- If the caliper brake line was disconnected, uncap and connect the brake hose to the caliper using new washers. Tighten the mounting bolt to 35 ft. lbs. (44 Nm).
- Refill the master cylinder and bleed the brake system.
- Install the tire and wheel assembly and tighten to 100 ft. lbs. (140 Nm).
- Lower the vehicle. Verify correct brake operation.
See Figures 8, 9, 10, 11, 12, 13, 14 and 15
Some vehicles may be equipped dual piston calipers. The procedure to overhaul the caliper is essentially the same with the exception of multiple pistons, O-rings and dust boots.
- Remove the caliper from the vehicle and place on a clean workbench.
Depending upon the vehicle, there are two different ways to remove the piston from the caliper. Refer to the brake pad replacement procedure to make sure you have the correct procedure for your vehicle.
- The first method is as follows:
- Stuff a shop towel or a block of wood into the caliper to catch the piston.
- Remove the caliper piston using compressed air applied into the caliper inlet hole. Inspect the piston for scoring, nicks, corrosion and/or worn or damaged chrome plating. The piston must be replaced if any of these conditions are found.
- For the second method, you must rotate the piston to retract it from the caliper.
- If equipped, remove the anti-rattle clip.
- Use a prytool to remove the caliper boot, being careful not to scratch the housing bore.
- Remove the piston seals from the groove in the caliper bore.
- Carefully loosen the brake bleeder valve cap and valve from the caliper housing.
- Inspect the caliper bores, pistons and mounting threads for scoring or excessive wear.
- Use crocus cloth to polish out light corrosion from the piston and bore.
- Clean all parts with denatured alcohol and dry with compressed air.
- Lubricate and install the bleeder valve and cap.
- Install the new seals into the caliper bore grooves, making sure they are not twisted.
- Lubricate the piston bore.
- Install the pistons and boots into the bores of the calipers and push to the bottom of the bores.
- Use a suitable driving tool to seat the boots in the housing.
- Install the caliper in the vehicle.
- Install the wheel and tire assembly, then carefully lower the vehicle.
- Properly bleed the brake system.
