Install

  1. Install the brake HCU, and back to the current procedure before bleeding the calipers. See Service Brake HCU Electricaltronic Control Unit Kit (Remove and Install).
  2. Reinstall the vehicle firmware. See Software Reinstall - Touchscreen.
  3. Locally connect a laptop with Toolbox 3 to the vehicle. See Toolbox 3 (Connect and Disconnect).
  4. Clean the area around the brake fluid reservoir breather cap and remove the cap.
  5. Add clean brake fluid to the full level in the bleeder reservoir.
  6. Add clean brake fluid to the MAX level in the reservoir.
  7. Install the pressure bleeder adapter onto the vehicle brake reservoir.
  8. Connect power supply to the bleeder tool, and then turn the bleeder tool on.
  9. Set the brake bleed reservoir pressure to 30 PSI, and then attach the brake bleed reservoir to the brake bleed adapter.
  10. Bleed the inner valve of the LH front caliper.
    1. Remove the LH front caliper inner bleed valve cover, and then install the fluid catcher.
    2. Open the inner bleed valve and watch the fluid as it flows out of the caliper.
    3. In Toolbox, click on the Actions/Autodiag tab, and then search for "Bleed FL".
    4. Click PROC_ESP_FRONT-L-REAR-R_BRAKE-BLEEDvia Toolbox: (link), click Run and allow the routine to complete.
    5. Close the bleed valve when the pump stops.
    6. Make sure that the reservoir does not go empty, or that the catch bottle does not overfill.
    7. Repeat step 10.b through step 10.f until clean fluid without bubbles flows out of the caliper.
    8. Remove the fluid catcher, and then torque the LH front caliper bleed valve and install the valve cap.

      Note

      If the test fails due to leakage, identify and address the root cause of the leak.

      If the test fails due to stiffness, perform a brake fluid bleed procedure on the failed caliper.

      If the test still fails after completing the brake fluid bleed procedure on the failed caliper, proceed with the Advanced Bosch Brake Fluid Bleed/Flush (Maintenance) Procedure.
