Disc Brake Caliper Guide Pin

DISC BRAKE CALIPER GUIDE PINS - FRONT
REMOVAL

NOTE: Before proceeding, Refer to Service Precautions.

1) Remove master cylinder fluid reservoir cap.
2) Raise and support vehicle.
3) Remove tire and wheel assembly.





4) Place an appropriately sized C-Clamp over brake caliper as shown (Fig. 44), placing screw-drive head against outboard shoe and hook against rear of caliper. Slowly tighten screw-drive retracting caliper pistons into bores and breaking outboard brake shoe free from caliper fingers. Do not overtighten C-Clamp. Remove C-Clamp.
5) Once outboard shoe is free from caliper fingers, slide caliper inboard on guides providing clearance between the rotor and inboard brake shoe.
6) Slide an appropriate prying tool though center opening in top of caliper behind inboard brake shoe between two caliper pistons. Use care not to come in contact with pistons or dust boots potentially damaging them. Pry against rear of inboard brake shoe breaking it free from caliper pistons.
7) Install master cylinder fluid reservoir cap.





8) Remove two brake caliper guide pin bolts (Fig. 45).
9) Remove disc brake caliper from brake adapter and hang out of way using wire or a bungee cord.
Use care not to overextend brake hose when doing this.





10) Remove guide pins and boots from adapter as shown (Fig. 46).

INSTALLATION
1) Lubricate guide pins and inside boots with packet supplied with service kit, Sythesco GLK-1 lubricant or equivalent.
2) Install guide pins and boots in adapter as shown (Fig. 46). The boots have grooves built into their inner lips to fit onto pins and adapter.

CAUTION: If adhesive is missing from noise suppression gasket on rear of either inner and outer brake shoes or if gasket is damaged, replace brake shoes.

CAUTION: Use care when installing caliper onto disc brake adapter to avoid damaging boots on caliper guide pins.

3) Install disc brake caliper over brake shoes on brake caliper adapter.
4) Align caliper guide pin bolt holes with guide pins, then install caliper guide pin bolts (Fig. 45). Tighten upper (closest to bleeder screw) bolt to 43 Nm (32 ft. lbs.) torque, then tighten lower bolt to 43 Nm (32 ft. lbs.) torque.
5) Install tire and wheel assembly. Tighten wheel mounting nuts to 135 Nm (100 ft. lbs.) torque.
6) Lower vehicle.
7) Pump brake pedal several times to set shoes to brake rotor.
8) Check and adjust brake fluid level as necessary.
9) Road test vehicle making several stops to wear off any foreign material on brakes and to seat brake shoes.
