FRONT CALIPERS

REMOVAL:

Using a clean suction gun, remove approximately 2 / 3 of the brake fluid from the master cylinder. The reason for this is that the caliper pistons must be pushed back into their bores so the caliper can be removed from the rotor. This could cause the brake fluid to overflow from the reservoir onto painted surfaces or wiring.
Raise and safely support the vehicle on safety stands.
Mark the relationship of the wheel to the hub so it can later be installed in the same relationship. This helps retain the balance of the rotating assembly.
Remove the front tire and wheel assembly. Install two wheel lug nuts to keep the rotor on the hub.
Push the caliper piston(s) back into their bore(s) to provide clearance between the linings and rotor. Use a large C-clamp over the top of the caliper housing and against the back of the outboard pad. Slowly tighten the C-clamp until the piston(s) are pushed back into the caliper bore(s) enough to slide the caliper off the rotor.
Remove the brake hose bolt from the caliper end of the hose. There should be copper seal washers on each side of the hose fitting. Plug the openings in the brake hose to keep the brake fluid reservoir from draining.
Remove the caliper slide pin bolts and carefully work the caliper away from the rotor and caliper mounting bracket.

INSTALLATION:
Bottom the piston(s) in the caliper bore(s) using a C-clamp, if new brake pads are to be installed. Use a large C-clamp and a metal plate or wooden block across the face of the piston(s). Take care not to damage the piston(s) or caliper rubber dust boot(s). After bottoming the piston(s), carefully lift the inner edge of the caliper boot(s) next to the piston(s) and press out any trapped air. The boots must lay flat below the level of the piston face.
Install the brake pad.
Install the caliper over the rotor and mounting bracket and work into place. Make sure the bushings in the caliper bracket are still in place.
Connect the brake hose using new copper seal washers. Tighten the bolt to 32 ft. Lbs. (44 Nm).
Carefully lubricate the caliper mounting bolts (slide pins) using silicone grease. Do not lubricate the threads or the mounting bolts may tend to work loose. Install the caliper mounting bolts. Use a small flat-blade tool to push the pin boot over the shoulder of the mounting bolt. The pin boot must be securely in the groove of the mounting bolt. Torque the caliper mounting bolts to 80 ft. Lbs. (108 Nm).
Install the tire and wheel assembly, aligning the balance marks made at removal.
Lower the vehicle.
Fill the master cylinder reservoir to the proper level using only fresh, clean DOT 3 brake fluid. Pump the brake pedal firmly to push the pistons back out into operating position and to seat the lining.
Bleed the brake system.

Rear Disc Brake Calipers
WITH BUILT-IN PARKING BRAKE MECHANISM

REMOVAL:

Using a suction gun, remove approximately 2 / 3 of the brake fluid from the master cylinder. The reason for this is that the caliper pistons must be pushed back into their bores so the caliper can be removed from the rotor. This could cause the brake fluid to overflow from the reservoir onto painted surfaces or wiring.
Raise and safely support the vehicle on safety stands.
Mark the relationship of the wheel to the hub so it can later be installed in the same relationship. This helps retain the balance of the rotating assembly.
Remove the rear tire and wheel assembly. Install two wheel lug nuts to keep the rotor on the hub.
Disconnect the brake line to the caliper. Plug the opening so all of the brake fluid does not drain from the master cylinder reservoir.
Remove the parking brake cable from the parking brake lever. Lift up on one end of the cable spring clip to free the end of the cable from the lever.
Remove the caliper slide pin bolts and carefully lift the caliper from its bracket.

INSTALLATION:
Bottom the piston into the caliper bore noting the following:
There is a special spanner-type tool designed to fit in the piston slots. This allows you to turn the piston and thread it into the caliper, retracting it. Use care if using a substitute tool. Careful work with suitable pliers may enable you to turn the piston back into its bore.
After bottoming the piston, lift the inner edge of the dust boot, next to the piston, and press out any trapped air. The boot must lay flat.

Install the caliper to the mounting bracket, noting the following:
If not replaced, remove the caliper mounting bolt boot from the caliper and install the small end over the tubular metal sleeve (installed on the caliper bracket). This is to prevent cutting the bolt boot when sliding the caliper body onto the sleeve.
Hold the caliper in position and start over the end of the sleeve. As the caliper approaches the boot, work the large end of the boot into the caliper groove. Then push the caliper fully onto the mounting bolt.
Pivot the caliper down, using care not to damage the piston dust boot on the inboard brake pad. Compress the mounting bolt boot by hand as the caliper moves into position to prevent boot damage.
After the caliper is in position, recheck the installation of the pad clips. If necessary, use a small flat-bladed tool to re-seat or center the pad clips on the mounting bracket.
Tighten the mounting bolts to 20 ft. Lbs. (27 Nm).

Install the cable support bracket. Connect the parking brake cable to the caliper lever. Lift up on the cable spring clip and work the end of the parking brake cable into the notch in lever.
Connect the brake fluid line. Use new copper washers, if equipped. Tighten the brake hose bolt to 32 ft. Lbs. (44 Nm).
Install the tire and wheel assembly, aligning the balance marks made at removal.
Lower the vehicle.
Fill the master cylinder reservoir to the proper level using only fresh, clean DOT 3 brake fluid. Pump the brake pedal firmly to push the pistons back out into operating position and to seat the lining.
Bleed the brake system.

Remove the brake caliper mounting bolts
Remove the caliper from the mounting bracket.

INSTALLATION:

Install the caliper upward in position. Use care not to damage the mounting bolt boots. Lubricate the mounting bolt and boot with silicone grease. Use care to keep grease off the mounting bolt threads to avoid having the mounting bolt loosen in service. Torque the mounting bolts to 33 ft. Lbs. (45 Nm).
Install the brake line to the caliper. Use new copper seal washers, if equipped. Torque the brake hose bolt to 40 ft. Lbs. (54 Nm).
Install the tire and wheel assembly, aligning the balance marks made at removal.
Lower the vehicle.
Fill the master cylinder reservoir to the proper level using only fresh, clean DOT 3 brake fluid. Pump the brake pedal firmly ( 3 / 4 of a full stroke) as many times as necessary to push the piston back out into operating position, seat the linings and obtain a firm brake pedal.
Bleed the brake system.
