Need some help. I've got a one year old tandem axle aluminum trailer, made out of state, that won't back up all the time. It backs fine on smooth surfaces like boat ramps, but when I hit any rough spot or back for more than 35 feet, the brakes lock up. By rough I mean an easy gravel drive or concrete to grass transition. Its making me crazy. I don't have alot of time to trouble shoot as there isn't enough daylight as it is, to get important things take care of. Any ideas as to a cause and fix, or someone in west or nw houston to take it to?-Tom

disk or drum brakes?

surge brakes?

Are they surge breakes? If they are, are you locking the reverse pin in it's place.

They could even be electric surge brakes. Install reverse pin and or wire it into your back up lights. it's malfunctioning though if it lets you back up sometimes.

Mine have an electric cut off that work off of the reverse lights. It has a flat 5 plug on the trailer. The extra slot is to disengage the brakes when in reverse.

Electric Surge disk

I've got a 5 way flat connection to the truck. I also have a seperate single connection from my left tail light that I used before I had the proper 5 way connection. Neither works consistently. The most confusing part is the way they lock up when I hit the slightest surface change. For example, they backed fine at the boat ramp in Baffin this weekend. But when I would back off the concrete drive onto the gravel road at the rented house, as soon as I hit the transition with the rear tires, LOCK!?-Tom

hose the connection down with WD40. That selenoid has to be on to back up and if you lose power to it, the brakes will lock. The bump of changing surfaces is what is causing it to not work right.

Bad corroded ground. Working intermittently.
