Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Brake Release Switches
All models use two methods of disengaging system once it has been activated. An electric switch mounted at brake pedal cuts off voltage to transducer unit and disengages it whenever brake pedal is depressed. Operation of engagement switch is required to re-activate system. A vacuum release valve (also mounted at brake pedal) operates simultaneously with or directly after the electric switch to vent vacuum in transducer to atmosphere, which will also disengage system should electric switch fail.
