REMOVAL & INSTALLATION



  1. Disconnect the negative battery cable. Wait at least 90 seconds once the battery cable is disconnected before working on the vehicle. This will hinder the deployment of the air bags.

CAUTION
All models covered by this guide are equipped with a Supplemental Restraint System (SRS), which uses an air bag. Whenever working near any of the SRS components, such as the impact sensors, the air bag module, steering column and instrument panel, disable the SRS, as described in Section 6.

  1. Label and disconnect the electrical harnesses.
  2.  
  3. Disconnect the hydraulic lines from the brake actuator. Plug the ends of the lines to prevent loss of fluid.
