Without Traction Control

NOTE: The illustration shows the hydraulic control module of a 6 cyl. vehicle.

REMOVAL
1. Raise the vehicle.
2. Displace the bleeder screw dust cap of the front LH caliper. The dust cap will remain captive on the bleed screw.
3. Connect a bleeder tube and bottle to the bleeder screw (1) and open the bleeder screw.
4. Fit a brake pedal hold-down tool (JDS-9013) between the brake pedal and the steering wheel. Adjust the tool to operate the brake pedal 60mm down. This operation is necessary to prevent fluid loss from the reservoir through disconnected brake pipes.
5. Re-tighten the front LH caliper bleeder screw. Disconnect the bleeder tube from the bleeder screw and remove the tube and bottle. Refit the bleeder screw dust cap.





6. Undo the securing bolt of the multi-plug connector (1). The bolt will remain captive. Disconnect the multiplug connector and reposition safely.
7. Place absorbent material underneath the hydraulic control module to absorb any spillages.
8. Undo the tandem master cylinder (TMC) brake pipe gland nuts (2) and disconnect the brake pipes.
9. Fit plugs immediately to the brake pipes and the hydraulic control module to prevent fluid loss.

NOTE:
^ Undo the rear brake pipe gland nuts (3) at the pressure conscious reducing valves (PCRVs) (4). Remove the rear brake pipes.
^ Take necessary steps to prevent rotation of the PCRVs when removing the rear brake pipes.

10. Fit plugs immediately to the brake pipes and the PCRVs to prevent fluid loss.
11. Undo and remove the PCRVs. Fit plugs immediately to the PCRVs and the hydraulic control module.
12. Place PCRVs aside to be fitted later to the new hydraulic control module.
13. Undo the front brake pipe gland nuts (5) and remove the front brake pipes.
^ Fit plugs immediately to the brake pipes and the hydraulic control module to prevent fluid loss.
14. Undo and remove the three securing nuts (6) and remove the hydraulic control module.
15. Remove the absorbent material and clean the mounting bracket and surrounding area.

INSTALLATION
1. Fit and align a new hydraulic control module to the mounting bracket. Ensure that the mounting cup tangs fully engage the bracket slots.
2. Fit and tighten the securing nuts (6).
3. Place absorbent material underneath the hydraulic control module to absorb any spillages.
4. Connect the front hydraulic brake pipes (5) to the hydraulic control module, removing plugs immediately prior to connection. Tighten the gland nuts.
5. Fit the PCRVs (4) to the hydraulic control module, removing plugs immediately prior to connection. Tighten the PCRVs.
6. Connect the rear hydraulic brake pipes (3) to the PCRVs, removing the plugs immediately prior to connection. Tighten the gland nuts.

NOTE:
^ Take necessary steps to prevent rotation of the PCRVs when fitting the rear brake pipes.

7. Connect the TMC hydraulic brake pipes (2) to the hydraulic control module, removing the plugs immediately prior to connection. Tighten the gland nuts.
8. Remove the absorbent material and clean the surrounding area.
9. Reposition and connect the multi-plug connector. Tighten the securing bolt (1).
10. Ensure that all fixings are torque tightened to specified tolerances.
11. Release the brake pedal hold-down tool and remove.
12. Bleed the brake system. Brake Bleeding

NOTE: Examine the hydraulic control module for leaks.
