Begin service of the rear brake caliper by first removing the rear wheel and applying torque to 103 Nm (1,050 kgf-cm, 76 ft.lbs). The service of the rear brake caliper requires hose disconnect by replacing its union bolt and 2 gaskets with new ones and catching drainage brake fluid in a container before securing the hose lock inside the caliper's lock hole with a final torque of 30 Nm (310 kgf-cm, 22 ft. lbs.). It is necessary to remove the caliper after uninstalling the 2 installation bolts with 44 Nm (449 kgf-cm, 33 ft. lbs.) torque strength followed by removal of the brake pads through pad protector and clip then the 2 pad guide pins and anti-rattle spring before extracting the 2 pads with 4 anti-squeal shims. Use a screwdriver to disassemble the set ring and cylinder boot before placing a cloth between the piston and caliper and then remove the piston with compressed air while avoiding placing fingers in front of it. A screwdriver removes the piston seal so you can extract the 2 sliding pins along with their 3 dust boots. Examine the pad lining thickness with a ruler to confirm it exceeds 1.0 mm (0.039 in.) minimum, also inspect the disc with a micrometer and replace it if its thickness falls below 8.0 mm (0.317 in.). To minimize runout the disc should be measured with a dial indicator at 10 mm (0.39 in.) from its outer edge. Any reading higher than 0.10 mm (0.0039 in.) requires readjustment through hub nut removal followed by disc turning and reinstallation at 103 Nm (1,050 kgf-cm, 76 ft. lbs.) until minimal runout reading is achieved. Replace the disc because its minimum runout measure is above 0.05 mm (0.0020 in.). The reverse disassembly process guides assembly with the application of specified parts lubricated by lithium soap base glycol grease followed by step-by-step installation in the opposite order of removal. The process ends by filling brake fluid into the reservoir followed by brake system bleeding before verifying no fluid leakage occurs.
