Caliper Removal/Installation

Four-Piston Caliper Assembly:






Removal

1. Raise vehicle on a hoist.
2. Remove wheel.
3. Clean dirt from brake hose connections. On front caliper, disconnect the brake hose at brake pipe support bracket. On rear caliper, disconnect the brake tubing from the inboard caliper. Tape the open tube or pipe end to prevent foreign matter from entering the system.
4. Remove the caliper assembly from the mounting bracket by removing two hex head bolts.

Installation

Replacing Shoe And Lining Assembly:




1. Carefully mount the assembled caliper over the edge of the disc. Use two screwdrivers to depress pistons so that the caliper can be lowered into position on the disc. Use care to prevent damage to boots on the edge of the disc as the caliper is mounted.
2. Secure the caliper to the mounting bracket with two hex head bolts.
If replacing old shoe assemblies, be sure to install the shoes in the same position from which they were removed.
3. Install the shoe and lining assemblies.
4. Place a new copper gasket on the male end of the front wheel brake hose. Install brake hose in the calipers. With the wheels straight ahead, pass the female end of the brake hose through the support bracket.
5. Make sure the tube seat is clean and connect the brake line tube nut to the caliper. Tighten securely.
6. Allowing the hose to seek a normal position without twist, insert hex of the hose fitting into the hole in the support bracket and secure it in place with the "U" shaped retainer (maximum allowed twist is ±1 notch). Turn the steering geometry from lock to lock while observing the hose. Check that the hose does not touch other parts at any time during suspension or geometry travel. If contact does occur, remove the "U"-shaped retainer and rotate the end of the hose in the support bracket in a direction which will eliminate hose contact. Reinstall the retainer and recheck for hose contact. If it is satisfactory, place the steel tube connector in the hose fitting and tighten securely.
7. If rear brake caliper is being serviced, connect brake line to caliper.
8. Bleed brakes.
9. Install wheels and lower vehicle.

CAUTION: Do not move car until a firm pedal is obtained.
