NOTE:
- Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid gets on the paint, wash it off immediately with water.
- To prevent dripping brake fluid, cover disconnected hose joints with rags or shop towels.
- Do not twist the brake hose and line when removed.
- Drain the brake fluid.

- Remove the brake lines (E) from the 4-way joint (F).
- Remove the brake 4-way joint.
- Remove the right (A) and left (B) pressure sensors from the brake 4-way joint (C).
- Install the parts in the reverse order of removal with new O-rings (D).NOTE: Make sure the connector colors and pressure sensor locations are correct.
- After installation, refill the brake fluid, and bleed the brake system (see BRAKE SYSTEM BLEEDING ).
- Do these checks:
- Check the brake hose and line joint for leaks, and tighten if necessary.
- Check the brake hoses for interference and twisting.
- Connect the HDS to the data link connector.
- Turn the ignition switch ON (II).
- Turn the adaptive cruise control (ACC) switch ON.

- Select ADAPTIVE CRUISE CONTROL (ACC) from ACC/CMBS menu, then enter FUNCTION TEST.
- Activate BRAKE ACTUATOR 3 from the FUNCTION TEST.NOTE: BRAKE ACTUATOR 3 operates the adaptive cruise control brake in this order (pressurization-stop-pressurization-stop). It takes about 6 seconds.
- Check for DTCs with the HDS.
- If there is a DTC, go to the INDICATED DTCS TROUBLESHOOTING .
- If there is no DTC, the brake pressure sensor replacement is complete.
