Question:
How do I know if my trailer is equipped with free backing brakes? I need to replace the surge brake hitch the current hitch does have some sort of lever for backing only but never have used it.

Expert Reply:
Your trailer must have free backing brakes if you have never used the surge brake actuating coupler reverse lockout. If you did not have free backing brakes, your brakes would most likely brake even if they didn't lock up when you back up because of the trailer weight pushing against the hitch ball.
The only way to know for sure is to pull your hub/drum off the spindle and look at the hydraulic cylinder. Free-backing brakes like # AKFBBRK-7R-D will have only one pin coming out and it will be toward the front brake shoe. If it has a pin on each side, then it is not a free-backing assembly.
