Installation
WARNING: ALTHOUGH FACTORY INSTALLED BRAKE LININGS ARE MADE FROM ASBESTOS FREE MATERIALS, SOME AFTER MARKET BRAKE LINING MAY CONTAIN ASBESTOS. THIS SHOULD BE TAKEN INTO ACCOUNT WHEN SERVICING A VEHICLE'S BRAKE SYSTEM, WHEN AFTER MARKET BRAKE LININGS MAY HAVE BEEN INSTALLED ON THE VEHICLE. ALWAYS WEAR A RESPIRATOR WHEN CLEANING BRAKE COMPONENTS AS ASBESTOS CAN CAUSE SERIOUS BODILY HARM SUCH AS ASBESTOSIS AND OR CANCER. NEVER CLEAN BRAKE COMPONENTS BY USING COMPRESSED AIR, USE ONLY A VACUUM CLEANER SPECIFICALLY DESIGNED FOR THE REMOVAL OF BRAKE DUST. IF A VACUUM CLEANER IS NOT AVAILABLE, CLEAN BRAKE PARTS USING ONLY WATER DAMPENED SHOP TOWELS. DO NOT CREATE BRAKE LINING DUST BY SANDING BRAKE LININGS WHEN SERVICING A VEHICLE. DISPOSE OF ALL DUST AND DIRT SUSPECTED OF CONTAINING ASBESTOS FIBERS USING ONLY SEALED AIRTIGHT BAGS OR CONTAINERS. FOLLOW ALL RECOMMENDED SAFETY PRACTICES PRESCRIBED BY THE OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION (OSHA) AND THE ENVIRONMENTAL PROTECTION AGENCY (EPA), FOR HANDLING AND DISPOSAL OF PRODUCTS CONTAINING ASBESTOS.GENERAL INFORMATION
During service procedures, grease or any other foreign material must be kept off brake shoe assemblies, and braking surfaces of brake drum and external surfaces of hub/bearing assembly. Handling of the braking disc and caliper. Should be done in such a way as to avoid deformation of the disc and scratching or nicking of brake linings. If inspection reveals that the square sectioned caliper piston seal is worn or damaged, it MUST be replaced immediately. During removal and installation of a wheel and tire assembly, use care not to strike the caliper.
CALIPER INSPECTION
Check for piston seal leaks (brake fluid in and around boot area and inboard lining) and for any ruptures of the piston dust boot. If boot is damaged, or fluid leak is visible, disassemble caliper assembly and install a new seal and boot, (and piston if scored). Refer to Disc Brake Caliper Service and Repair Disassembly. Check the caliper dust boot and caliper pin bushings to determine if they are in good condition. Replace if they are damaged, dry, or found to be brittle.
PROCEDURE
NOTE: Step 1 below is only required when installing a 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. Install the rear rotor on the hub, making sure it is squarely seated on the face of the hub.
4. Remove the protective paper from the noise suppression gasket on both the inner and outer brake shoe assemblies (if equipped).
Removing Installing Inboard Brake Shoe:
5. Install the new inboard brake shoe assembly into the caliper piston by firmly pressing into piston bore with thumbs. Be sure inboard. brake shoe assembly is positioned squarely against the face of the caliper piston.
Removing / Installing Outboard Brake Shoe:
6. Slide the new outboard brake shoe assembly onto the caliper assembly.
CAUTION: Use care when installing the caliper assembly onto the adapter, so the caliper guide pin bushings do not get damaged by the mounting bosses.
Removing/Installing Caliper Assembly:
7. Carefully lower caliper and brake shoes over rotor and onto adapter, reversing the removal procedure.
CAUTION: When installing the caliper guide pin bolts extreme caution should be taken not to crossthread the guide pin bolts.
8. Install the caliper guide pin bolts. Tighten the guide pin bolts to a torque of 22 Nm (192 in. lbs.).
9. Install the wheel and tire assembly.
10. 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 110 - 135 Nm (85 - 115 ft. lbs.).
11. Remove jackstands or lower hoist.
CAUTION: Before moving vehicle, pump the brake pedal several times to insure the vehicle has a firm brake pedal to adequately stop the vehicle.
12. Road test the vehicle and make several stops to wear off any foreign material on the brakes and to seat the brake shoe linings.
