FRONT BRAKE PAD AND CALIPER INSTALLATION
ý
WARNING
• If at any point in this procedure the hydraulic system is opened, the brakes must be bled after
the correct reinstallation of the brake components. Failure to bleed the brakes could result in
decreased braking performance due to air being trapped in the hydraulic system. Use only
DOT 5 brake fluid. See Bleeding the Hydraulic Brake System on page 5-22.
Front Brake Caliper Installation
1. Secure the caliper body to the upright with two hex-head bolts. Apply Loctite # 277 to the bolt thread, and
tighten the hardware to 36 ft-lb (49 N·m).
2. Secure the brake line to the caliper with a new banjo bolt and new copper washers. Tighten to 13 ft-lb
(18 N·m). See following CAUTION.
ý
CAUTION
• The banjo bolts are metric. Use only metric thread replacements.
3. Bleed the brake line at the top bleed port on the caliper body. Tighten the port fitting to 27 in-lb (3 N·m).
See following NOTE.
NOTE: Front wheel calipers for this vehicle are equipped with two bleed ports. These calipers can be used
on either the left or right side. Always bleed the top port.
Individual bleeding of the hydraulic ports at the caliper requires an assistant to press the brake
pedal or operate special brake bleeding equipment.
4. Repeat steps 1 through 3 for the opposite front wheel if necessary.
Front Brake Pad Installation
1. Install the brake pads and install the socket-head slide-pin bolts through top and bottom holes of pads.
Tighten the hardware to 32 ft-lb (43 N·m).
2. Install the tire and wheel. Finger-tighten the lug nuts.
