Rear Disc Brake Caliper
DISC BRAKE CALIPER REAR SRT4REMOVAL
NOTE: Before proceeding, Refer to Service Precautions.
1. Using a brake pedal holding tool, depress the brake pedal past its first one inch of travel and hold it in this position. This will isolate the master cylinder from the brake hydraulic system and will not allow the brake fluid to drain out of the master cylinder reservoir while the lines are disconnected.
2. Raise the vehicle.
3. Remove the rear tire and wheel assembly.
4. Remove the banjo bolt connecting the brake hose to the brake caliper. There are two washers (one on each side of the flex hose fitting) that will come off with the banjo bolt. Discard the washers.
NOTE: In some cases, it may be necessary to retract the caliper piston in its bore a small amount in order to provide sufficient clearance between the shoes and the rotor to easily remove the caliper from the knuckle. This can usually be accomplished before the guide pin bolts are removed, by grasping the rear of the caliper and pulling outward working with the guide pins, thus retracting the piston. Never push on the piston directly as it may get damaged.
5. Remove the two caliper guide pin bolts.
Caliper Removal/Installation:
6. Remove the caliper assembly from the brake adapter by first rotating the top of the caliper away from the rotor, and then lifting the caliper assembly off the machined abutment on the adapte.
INSTALLATION
CAUTION: When installing new brake components, be sure to use correct parts. Parts designed for BR3 Performance Brake System must not be mixed with other brake systems. These- parts, similar in appearance, can be easily identified.
NOTE: Step (1) below is only required when installing the disc brake caliper after new brake shoes have been installed.
1. Completely retract the caliper piston back into piston bore of the caliper.
2. Lubricate both adapter caliper slide abutments with a liberal amount of leopard Multipurpose Lubricant, or an equivalent.
CAUTION: Use care when installing the caliper assembly onto adapter so the guide pin bushings and sleeves do not get damaged by the mounting bosses on adapter.
3. Starting with the lower end, carefully lower the caliper and brake shoes over the brake rotor and catch the caliper's bottom edge behind the caliper slide abutment. Rotate the top of the caliper into mounting position on the adapter.
CAUTION: Extreme caution should be taken not to cross thread the caliper guide pin bolts when they are installed.
4. Carefully install the caliper guide pin bolts, then tighten them to a torque of 22 Nm (192 inch lbs.).
5. Install the banjo bolt connecting the brake hose to the brake caliper. Install NEW washers. Place one fitting washer on each side of the hose fitting as the banjo bolt is guided through the fitting. Thread the banjo bolt into the caliper and tighten it to a torque of 24 Nm (210 inch lbs.).
6. Install the tire and wheel assembly. Tighten the wheel mounting nuts to a torque of 135 Nm (100 ft. lbs.).
7. Lower the vehicle.
8. Remove the brake pedal holding tool.
9. Bleed the caliper as necessary.
10. Road test the vehicle and make several stops to wear off any foreign material on the brakes and to seat the brake shoes.
