Caution: Refer to Brake Dust Caution in the Preface section.
Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Caution: Do not place your fingers in front of the piston in order to catch or protect the piston while applying compressed air. This could result in serious injury.
Important: The brake calipers contain phenolic pistons that have stainless steel caps that contact the brake pad. Use compressed air to remove the piston from the caliper.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten
Tighten the screw to 12 N·m (106 lb in).
7.1. | Install the boot over the end of the piston so that the fold will face toward the brake caliper housing piston bore opening. |
7.2. | Seat the boot into the brake caliper bore groove. Slide the piston into the brake caliper bore. |
7.3. | Push down the piston to the bottom of the caliper bore. |
7.4. | Ensure the boot seats properly into the piston groove and into the groove in the caliper bore. |
7.5. | Repeat steps 5 and 6 for the remaining piston. |
