Removal and 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 aftermarket 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 caliper assembly, surfaces of braking rotor and external surfaces of hub.
Handling of the brake rotor and caliper should be done in such a way as to avoid deformation of the rotor and scratching or nicking of the brake linings.
If inspection reveals that the square sectioned caliper piston seal is worn or damaged, it should be replaced immediately.
During removal and installation of a wheel and tire, use care not to strike the caliper.
NOTE: Before vehicle is moved after any brake service work, pump the brake pedal several times to insure the vehicle has a firm brake pedal.
NOTE: Starting with the 1998 model year, different lining material is used on the disc brake shoes depending on the type of brake system the vehicle is equipped with. Vehicles equipped with standard front disc and rear drum brakes use a new lining material on the front disc brake shoes. Vehicles that are equipped with optional 4 wheel disc brakes use a new lining material on both the front and rear disc brake shoes. When new brake shoes are installed, be sure brake shoes for the correct model year and type of brake system the vehicle is equipped with are used.
REMOVE
1. Raise vehicle on jackstands or centered on a hoist.
2. Remove rear wheel and tire assemblies from vehicle.
Caliper Assembly Guide Pin Bolts:
3. Remove the 2 caliper assembly to adapter guide pin bolts.
Caliper Removal/Installation:
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.
Storing Caliper:
5. Support caliper assembly firmly from rear strut to prevent weight of caliper from damaging the flexible brake hose.
6. Remove rear rotor from hub/bearing assembly. Then inspect drum-in-hat parking brake shoes and parking brake braking surface on rotor for any signs of excessive wear or damage. Replace parking brake shoes if required.
Outboard Brake Shoe:
7. Remove outboard brake pad from caliper by prying brake pad retaining clip over raised area on caliper. Then slide brake pad down and off the caliper.
Removing Installing Inboard Brake Shoe:
8. Pull inboard brake pad away from caliper piston, until retaining clip is free from cavity in piston.
CALIPER INSPECTION
Check caliper 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 and install a new seal and boot, (and piston if scored).
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.
INSTALL
1. Completely retract the caliper piston back into the piston bore of the caliper assembly. This is required for caliper installation when new brake pad assemblies are installed on caliper.
2. Lubricate both adapter abutments with a liberal amount of Mopar Multipurpose Lubricant, or equivalent.
3. Install rear rotor on the hub making sure it is squarely seated on face of hub.
4. Remove protective paper from noise suppression gasket on both inner and outer brake pad assemblies (if equipped).
5. Install new inboard brake shoe assembly into caliper piston by firmly pressing into piston bore with thumbs. Be sure inboard brake shoe assembly is positioned squarely against face of caliper piston.
6. Slide new outboard brake pad assembly onto the caliper assembly. Be sure retaining clip is squarely seated in the depressed areas on the caliper.
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.
7. Carefully lower caliper and brake shoe assemblies over braking disc (rotor) reversing the required removal procedure. Make sure that 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.
8. Install caliper assembly guide pin bolts into adapter and tighten. Then torque both guide pin bolts to 22 Nm (192 inch 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 135 Nm (100 ft. lbs.).
11. Remove jackstands or lower hoist. Before moving vehicle, pump the brake pedal several times to insure the vehicle has a firm brake pedal.
12. Road test the vehicle and make several stops to wear off any foreign material on the brakes and to seat the brake pads.
