Fig. 4 Rear Caliper Assembly Removal:

After performing any service work, obtain a firm brake pedal before moving vehicle.
1. Raise vehicle and support on safety stands, then remove tire and wheel assemblies.
2. Disconnect fitting on rear brake tube from hose end fitting at frame mounted bracket and plug end of brake tube to prevent loss of fluid and entry of dirt. Remove horseshoe retaining clip from hose fitting and disengage hose from bracket.
3. Disconnect parking cable from lever, Fig. 3, using care to avoid kinking or cutting cable or return spring, then remove retaining screw from caliper retaining key, Fig. 4, then remove caliper locating pins.
4. Slide caliper retaining key and support spring from anchor plate, Fig. 4. If necessary, use a hammer and brass drift, being careful to avoid damaging key on sliding ways or hitting parking brake lever. If caliper cannot be removed due to rust build-up on outer edge of rotor, scrape off loose scale, being careful not to damage braking surfaces. If rotor wear or scoring prevents removal of caliper, it will be necessary to loosen caliper end retainer {1-2} turn maximum, to allow piston to be forced back into its bore. To loosen end retainer, remove parking brake lever and mark or scribe end retainer and caliper housing to be sure that end retainer is not loosened more than {1-2} turn, then force piston back in its bore, Fig. 2, and move caliper back and forth to center rotor and remove caliper. If retainer must be loosened more than {1-2} turn, use caution, as the seal between the thrust screw and housing may be broken and brake fluid will enter parking brake mechanism chamber. In this case, the end retainer must be removed and the internal parts cleaned and lubricated.
5. Remove outer shoe and lining assembly from anchor plate, then remove rotor retainer nuts and rotor from axle shaft.
6. Remove inner brake shoe and lining assembly from anchor plate and mark each shoe for identification if they are to be reused.
7. Remove anti-rattle clip from anchor plate, then remove flexible hose from caliper by removing hollow retaining bolt.
