B. Replace Rear Brake Hose

NOTE:
Only those vehicles that have a worn brake hose, as determined by the inspection in Section "A", require replacement. Very few vehicles are expected to require brake hose replacement.

1. Lower the vehicle.

2. Depress and hold the brake pedal using a brake pedal prop rod.

NOTE:
Keeping the brake pedal in the "applied" position makes bleeding the brakes faster and easier since only the rear brakes will require bleeding.

3. Raise the vehicle on the hoist.





4. Disconnect the rear chassis brake tube from the rear brake hose and cap the brake tube (Figure 2).

NOTE:
DO NOT allow brake fluid to drip or spill on painted surfaces as this may damage the paint. If brake fluid contacts a painted surface, flush with water immediately.

5. Remove the retaining clip and disconnect the rear brake hose from the mounting bracket.





6. Disconnect the left and right rear brake tubes from the rear brake hose (Figure 3).

7. Remove the brake hose bracket nut from the RWAL/ABS speed sensor bracket (Figure 3).

8. Remove the rear brake hose from the clips and discard the brake hose.

9. Install the new brake hose into the clips.

10. Install the brake hose bracket onto the RWAL/ABS speed sensor bracket (Figure 3). Tighten the bracket nut to 195 in-lbs (24 Nm).

11. Connect the left and right brake tubes to the new brake hose (Figure 3). Tighten the brake tube fittings to 145 in-lbs (16 Nm).

12. Install the other end of the brake hose into the mounting bracket and install the retaining clip (Figure 2).

13. Connect the rear chassis brake tube to the rear brake hose (Figure 2). Tighten the brake tube fining to 145 in-lbs (16 Nm).

14. Bleed the left and right rear brake circuits as follows:

a. Attach a clear plastic hose to the right rear bleeder screw and feed the hose into a clear jar containing enough fresh brake fluid to submerge the end of the hose.

b. Have a helper pump the brake pedal three or four times and then hold it in the down position.

c. With the pedal in the down position, open the bleeder screw at least one full turn.

d. Once the brake pedal has dropped, close the bleeder screw. After the bleeder screw is closed, release the brake pedal.

e. Repeat steps b through d until all trapped air is removed from the right rear brake circuit (usually four or five times).

f. Repeat steps a through e for the left rear brake circuit.

15. Inspect brake hose connections to insure that there are no leaks.

16. Continue with Section "C - Reposition and Clip the Rear Axle Vent Hose."
