2001 Ranger Trail dual axle with UFP A60 actuator, DB42 calipers and a UFP 32220 reverse lockout solenoid. The DB42 caliplers are new, brakes bled. Once actuated, the brakes one release on ocassion. Not sure if it is just after backing up or if its after normal braking. Any known problems based on these symptoms? I need this fixed in 2 weeks for a trip, thinking about replacing the actuator and reverse lockout both just to be done with it but don't like throwing unnecessary parts at it either, I'm sure removing the actuator pins will be a pain as old as the trailer is so the reverse solenoid would be the easiest.
