If your brakes are locking up when you are using the Tekonsha Primus IQ Trailer Brake Controller # TK90160, then you need to decrease the gain on your controller using the blue dial on the left side. The proper adjustment should not lock your brakes but should come just short of doing so when using the manual override feature at 25 mph.

I've attached the instructions that recommend starting the process with the gain set to 6.0 to start this process without any boost turned on.
