Brakes locking up

[outdoordb]

My sister purchased a 2006 Star craft 23SRG towed it home from NJ to MD then from MD to GA with no problems. Then half way home on her return trip from GA when she applied the brakes they started grabbing and locking up. She backed them way off and made it home. She took it to a shop and they did a bunch of things totaling $600.00 Replaced shoes and magnets and turned drums and still locked up. She took it back and they swapped out controllers, ran a new wire from controller to back of vehicle adjusted brakes and it’s still real touchy and locks up at slower speed. They said they tested it on one of their trucks and it worked fine. She’stowing it with a 2004 Toyota 4Runner that has never towed anything prior to her buying it. They are now saying it may be her alternator putting out too much voltage. Any thoughts? Thanks

What Mike said, although the brakes on the trailer may have been bad as well.

What controller?
