Removal

NOTE: Removal steps in this procedure may contain installation details.

1.   WARNING: Service actions on vehicles equipped with electronic parking brakes may cause unexpected parking brake application, which could result in injury to hands or fingers. Put the electronic parking brake system into service mode prior to servicing or removing rear brake components. Failure to follow this instruction may result in serious personal injury.

   Activate the EPB service mode.
   Refer to: Electronic Parking Brake (EPB) Service Mode Activation and Deactivation (206-05 Parking Brake and Actuation, General Procedures).
   

1. Remove the wheel and tire.
   Refer to: Wheel and Tire (204-04A Wheels and Tires, Removal and Installation).
   

1. Remove and discard the brake caliper spring.
   

1. NOTICE: Do not pry in the caliper sight hole to retract the pistons as this can damage the pistons and boots.

   NOTICE: Do not allow the brake caliper and anchor plate assembly to hang from the brake hose or damage to the hose can occur.

   Remove the caps, the guide pins and position the brake caliper aside.
   Torque: 21 lb.ft (28 Nm)

1. NOTICE: Brake pads with adhesive on the insulator are one-time use only. When the brake pads are separated from the brake caliper, new brake pads must be installed to prevent brake noise and shudder.

   Remove and discard the brake pads.
   

1. NOTICE: Use care when pushing the caliper piston into the caliper piston bores or damage to components may occur.

   Compress the brake caliper piston until the piston bottoms out in the brake caliper bore.

   • NOTICE: Do not apply over 20 Nm (177 in-lb) force when rotating the brake caliper piston or internal damage to the brake caliper may occur.

     If the brake caliper piston bottoms out and the piston is still not fully compressed, rotate the piston clockwise while pushing inward using a brake caliper piston retractor until the piston is fully compressed. Use the General Equipment: Brake Caliper Piston Retractor
