Have to use the motor to run it out, which causes it to overheat and shut down. I have hooked it up and backed the jeep up in an attempt to 'break in' the brake and it is better, but still harder than you can pull out by hand.
Emailed MM asking for a skematic so I could see if there is any adjustment. They sent me two, both wrong even though I gave them the exact model. And this is their 'tech' guys.
