Brake System Bleeding - Project 8 (G2301174): Activation

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Braking efficiency may be seriously impaired if an incorrect bleed sequence is used.
CAUTION: Brake fluid will damage paint finished surfaces. If spilled, immediately remove the fluid and clean the area with water.
  1. Raise and support the vehicle on a suitable 2 post lift.

    Refer to: LIFTING

  2. Remove all 4 wheel and tire assemblies.

    Refer to: WHEEL AND TIRE - PROJECT 8

  3. Check the brake pipes and hoses are secure and there are no signs of a brake fluid leak. If a brake fluid leak is detected, investigate and rectify the cause of the brake fluid leak, before bleeding the brakes.
