Brake Release Switches

  1. The design of the electric switch and vacuum valve mounting provides for automatic adjustment when brake pedal is manually returned to its stop.
  2. Depress brake pedal fully and push switch and valve forward until they stop against bracket or arm. Pull brake pedal back up toward its stop with 15-20 lbs. (6.8-9.1 kg) of force.
