ing NOTE.
NOTE: Place a pan under each rear caliper assembly to collect the brake fluid.
Place a plastic bag around each caliper to prevent debris from entering the brake line ports. Do not

7. Remove the T-bracket from the passenger side on the rear receiver hitch frame.
8. Remove the brake line from the clamp locations under the vehicle frame and floorboard.

NOTE: Tie a heavy nylon string to the flare-nut end of the brake line before removal. Allow the string to
travel with the brake line until it clears the rear of the vehicle. During replacement, tie the flare-nut

REAR BRAKE LINE INSTALLATION
1. Feed a new brake line from the rear of the vehicle, and position it in line with the frame clamps and up
to the master cylinder. See following NOTE.

nut end of the new brake line. Use the string to pull the new brake line into position and to the mas-
ter cylinder.

3. Secure the brake lines to the clamp and grommet locations.
4. Secure the brake lines, banjo bolts, and new copper washers to each rear wheel caliper. Tighten the
hardware to 13 ft-lb (18 N·m). See following NOTE.

bracket on the shock absorber.
See following CAUTION.
