Principles of Operation

Parking Brake System

When the parking brake control is pressed, tension is applied to the intermediate parking brake cable. This tension pulls on the RH rear parking brake cable, which is attached to the RH rear parking brake actuator and applies the RH rear brake caliper. At the same time, the tension in the intermediate cable causes the intermediate cable conduit to attempt to straighten out. This straightening effect causes tension that pulls the LH rear cable, which is attached to the LH rear parking brake actuator, and applies the LH rear brake caliper.
