Caliper Removal/Installation:




Storing Caliper:





REMOVAL
1. Raise vehicle on jackstands or centered on a hoist.
2. Remove rear wheel and tire assemblies from vehicle.
3. Remove the 2 caliper assembly to adapter guide pin bolts.
4. Remove caliper assembly from adapter and rotor by first rotating top of caliper assembly away from adapter, and then lifting caliper assembly off lower machined abutment on adapter.
5. Support caliper assembly firmly from rear strut to prevent weight of caliper from damaging the flexible brake hose.





INSTALLATION

NOTE: Step 1 below is only required when installing the disc brake caliper, after new brake shoes have been installed.

1. Completely retract caliper piston back into piston bore of caliper assembly.
2. Lubricate both adapter abutments with a liberal amount of Mopar* Multipurpose Lubricant, or equivalent.
3. If removed, install the rear rotor on the hub making sure it is squarely seated on the face of the hub.

CAUTION: Use care when installing caliper assembly onto adapter so the guide pin bushings and sleeves do not get damaged by the mounting bosses on adapter.

4. Carefully lower caliper and brake shoe assemblies over braking disc (rotor) reversing the required removal procedure. Make sure that the caliper guide pin bolts, bushings and sleeves are clear of the adapter bosses.

CAUTION: Extreme caution should be taken not to cross thread the caliper guide pin bolts when they are installed.

5. Install caliper assembly guide pin bolts into adapter and tighten. Then torque both guide pin bolts to 22 Nm (192 in. lbs.).
6. Install the wheel and tire assembly.
7. Tighten the wheel mounting stud nuts in proper sequence until all nuts are torqued to half specification. Then repeat the tightening sequence to the full specified torque of 109 - 150 Nm (80 - 110 ft. lbs.).
8. Remove jackstands or lower hoist. Before moving vehicle, pump the brake pedal several times to insure the vehicle has a firm brake pedal.
9. Road test the vehicle and make several stops to wear off any foreign material on the brakes and to seat the brake pads.
