Trailer pulling to one side on braking...

Make sure the U-bolts holding the axle and spring together are tight and that you haven't sheared the alignment pin.

I would check the wiring in the trailer. Could be you have poor voltage to one side. Or bad ground or something. Wiring is always the first thing to go it seems.

+1 about this thought. If on one side there is a poor connection or other condition causing a voltage drop at the trouble spot, that could explain why one brake is exerting more braking force than the other. And although you would certainly expect a problem like this to be on the trailer, theoretically it could be on the vehicle side, possibly at the plug.

Jack up the trailer and set the tow vehicle brakes. Then start checking by trying to turn the wheels and amp draw on each brake.

Does the OP know how to check amperage?

Thank you for the additional suggestions to check the physical measurements, U-bolts, wiring, etc. - I'll be checking all those things.

Yes, I know how to check amperage - thanks.

Would someone like to explain how to check amp draw? Understand how to check voltage but not amp draw. Thanks, Jon

Fluke Clamp Meters, Amp Meters and Clamp On Ammeters or similar (Fluke will be expensive).

Just clamp it over the power or ground (not both) for a given brake (or whatever). When the wire is energised the meter will display current.

Most multimeters can be put in series (cut wire, splice the meter inline) & measure current as well. They are usually limited to 10@ at best. And it can be quite a pain to get the meter wired inline.

If they are self adjusting. Can't you try letting them. Backup while using brakes to adjust themselves?
