2021 Geo Pro 19FD brakes locking up
Using a Curt Wireless Brake controller. Trailer is five weeks old. Default settings of 4 and 50% on brake controller worked fine up until a couple days ago. Probably put between 2 and 3000 miles on the trailer. Below 30 mph just touching the brakes causes the tow vehicle and the trailer to jerk back and forth. Parking lot speeds are the worst. At the advice of tech support, I progressively lowered the assist in multiple steps to number 1 and 30%, which did nothing. Dealerships in the area can't see me for 3 to 6 weeks. Tech support on another call says I need my brakes adjusted, so I went online to figure out how so I could DIY. Videos online show turning a star wheel inside the brake hub with a flat bladed screwdriver, which sounded easy until I discovered there is no star wheel I can see through the access holes. Further online investigation says my brakes are self adjusting, so now I'm stumped. I'm a full timer on the road and can't hole up for 3 to 6 weeks in one locale. Any suggestions would be helpful. Thank you.
