J 36349 Front Dust Boot Seal Installer

1. Remove the rear brake caliper. Refer to Rear Brake Caliper Replacement .




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.

Notice: Use clean cloths to pad interior of caliper housing during piston removal. Use just enough air to ease the pistons out of the bores. If the pistons are blown out, even with the padding provided, it may be damaged.

2. Remove the piston. Blow compressed air (3) into the caliper inlet hole. The piston will come out through the piston boot.
3. Inspect the piston for the following conditions:

•

Scoring

•

Gouges

•

Cracks

•	Excessive wear

•

Corrosion

•	Replace the piston if any of the above conditions are found.




4. Remove the piston boot (2). Use a flat-bladed tool in order to lift one end of the boot ring. The piston boot ring may be stuck in the caliper groove.




Notice: Do not use a metal tool for seal removal. Damage to the caliper bore or the seal grooves can result.

5. Remove the piston seal (4) from the groove in the caliper body (3). Use a small wooden or plastic tool in order to manipulate the piston seal out of the caliper bore groove.
6. Remove the bleeder valve cap (1), the bleeder valve (2) from the caliper housing.
7. Inspect the caliper bore and the seal grooves for the following conditions:

•

Scoring

•

Gouges

•

Corrosion

•

Wear

8. Replace the caliper housing if corrosion in and around the seal groove cannot be cleaned with a crocus cloth. Do not hone the caliper bore.
9. Clean all the parts in clean, denatured alcohol.
10. Dry all the parts with filtered, non-lubricated compressed air.
11. Blow out all the passages in the caliper housing and the bleeder valve. Use filtered, non-lubricated compressed air.

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.

1. Install the bleeder valve (2) and the bleeder valve cap (1) to the caliper housing.

Tighten
Tighten the bleeder valve to 11 N·m(97 lb in).




2. Lubricate a new piston seal with clean brake fluid.
3. Install the piston seal into the caliper bore grooves. Ensure that the piston seal is not twisted.
4. Lubricate the piston boot with clean brake fluid.
5. Install the piston boot (1) onto the piston (2).
6. Lubricate the piston OD with clean brake fluid.



7. Install the piston and the boot into the bore of the caliper using the J 36349 .

7.1.	Ensure that the outside edge of the piston boot is seated smoothly in the counterbore of the caliper body.

7.2.	Lift the inner edge of the piston boot next to the piston. Press out any trapped air. Ensure that the boot lies flat.

8. Install the rear brake caliper. Refer to Rear Brake Caliper Replacement .
