Frequently Asked Questions:

1.  Can I convert my UFP drum brake system to a UFP disc brake system?

  • Yes you can.  Remove and replace inner member.  (See page 23 and 24 of A-60 owners manual found at www.ufpnet.com.)  Modify wiring to accommodate solenoid wire on trailer and connection to back up lights on tow vehicle.  Consult a professional with electrical wiring on tow vehicle.  (See Back Up Solenoid Wiring Diagram).  Remove Hub-Drums and brake assemblies from axle.  (Reverse the installation instructions) and install disc brake parts (See page 5 and 6 of Disc brake manual).  Reinstall actuator brake line and reinstall brake lines on axle (be sure to install a flex line before each caliper or bend a coil in the existing line to allow caliper to travel at least a half an inch).  Bleed trailer brakes (see page 26 and 27 of A-60 owners manual).
