Trailer Buddy/UFP Electric Reverse Solenoid Valve with Fittings #34500

Necessary for disc brake use, This electronically activated reversing solenoid prevents hydraulic pressure buildup whenever the tow vehicle is shifted into reverse.  Brake Fluid is routed back to the actuators master cylinder reservoir, no line pressure builds up and the trailer can easily be backed up. 

The electrical lead from the solenoid valve (usually a blue wire) must be connected to the tow vehicle's back-up lights.  A "click" should be heard when the tow vehicle is shifted into reverse and the back-up lights come on.  This solenoid valve is fail-safe.  That is, it will not open if it were to malfunction so the user will always have brakes when towing forward. Be sure to secure the white ground wire to the frame.

  • Controlled by the tow vehicles back-up light circuit
  • Solenoid comes with ground wire to improve on old models which were self grounded
  • Installs easily into the UFP Disc Brake Master Cylinder #34762
  • Works with hydraulic surge-type actuators

  • Includes inlet and outlet fittings
  • The white wire is a ground wire to be secured to the frame
