Lumina APV V6-191 3.1L VIN D TBI (1995)
Brake Switch (Cruise Control): Description and Operation
The brake switch is used to disengage the cruise control system when the brake and/or clutch pedal is depressed. The electrical release interrupts the
electrical signal to the controller to disengage the system. The vacuum release vents trapped vacuum in the servo into the atmosphere, allowing the servo
to return to throttle idle position. These release mechanisms can also be found combined with TCC and/or stop lamp switches.
