REMOVAL - REAR DISC BRAKE CALIPER
NOTE:Handling of the rotor and caliper, must be done in such a way as to avoid damage to the rotor and scratching or nicking of lining on the brake shoes.

Depress the brake pedal past its first inch of travel and hold it in this position using a brake pedal depressor (holding) tool. This is done to isolate the master cylinder from the brake hydraulic system disallowing the brake fluid to completely drain out of the brake fluid reservoir.
Raise the vehicle. (Refer to LUBRICATION & MAINTENANCE/HOISTING - STANDARD PROCEDURE)
Remove rear wheel and tire assembly from vehicle.
Remove the banjo bolt connecting the brake hose to the brake caliper. There are two washers (one on each side of the brake hose fitting) that will come off with the banjo bolt. Discard these washers.
Remove the disc brake caliper to adapter guide pin bolts. See Fig. 42.
