Raise vehicle and suitably support. Mark relationship of wheel to axle flange.
Wheel and tire. Reinstall two wheel nuts to retain rotor.
Brake hose from caliper, only if caliper is to be completely removed from vehicle for unit repair. Plug openings in caliper and brake hose to prevent fluid loss and contamination.
Parking brake cable from parking brake lever, only if caliper is to be completely removed from vehicle for unit repair. Lift up on end of cable spring to free end of cable from lever.
Bolt and washer attaching cable support bracket to caliper body assembly.
Sleeve bolt.
Caliper body assembly. Pivot caliper body assembly up to clear rotor and then slide inboard, off pin sleeve.
NOTE: Do not allow components to hang from the flexible brake hoses as damage to the hoses may occur. Some brake hoses have protective rings or covers to prevent direct contact of the hose with other chassis parts. Besides causing possible structural damage to the hose, excessive tension could cause the hose rings to move out of their proper locations. Inspect Pin boot, bolt boot and sleeve boot for cuts, tears or deterioration. If damaged, replace boots. Bolt sleeve and pin sleeve for corrosion or damage. Pull boots to gain access to sleeves for inspection or replacement. Replace corroded or damaged sleeves. Do Not attempt to polish away corrosion.

Caliper Installation

INSTALL OR CONNECT
Caliper assembly. If not replaced, remove pin boot from caliper body assembly and install small end over pin sleeve (installed on caliper support) until boot seats in pin grove. This is to prevent cutting pin boot when sliding caliper body assembly onto pin sleeve. Hold caliper body assembly in position it was removed and start over end of pin sleeve. As caliper body assembly approaches pin boot, work large end of pin boot in caliper body groove. Then push caliper body fully onto pin. Pivot caliper body assembly down, using care not to damage piston boot on inboard shoe. Compress sleeve boot by hand as caliper body moves into position to prevent boot damage. After caliper body assembly is in position, recheck installation of pad clips. If necessary, use a small screwdriver to reseat or center the pad clips on the support abutments.

Sleeve bolt. Tighten Torque to 27 Nm (20 ft. lbs.).
Cable support bracket with cable attached using bolt and washer. Tighten Torque to 43 Nm (32 ft. lbs.).
End of parking brake cable to parking brake lever if disconnected. Lift up on end of cable spring clip and work end of parking brake cable into notch in lever.
Brake hose to caliper if disconnected.
NOTE: Bleed brakes if brake hose was disconnected. Remove wheel nuts securing rotor to hub.

Wheels and tires, aligning previous marks. Lower vehicle. Torque wheel nuts.
Apply approximately 778 N (175 lb.) force to brake pedal (after bleeding, if necessary) three times to seat shoe and linings against rotor.

Please let me know if you need anything else to get the problem fixed.

Best, Ken
