When I am returning home from the lake, I feel the brake or brakes drag for a short time and then quit. By the time I get home is rolls fine. I suppose I have to buy 2 calipers ($80.00 each) and an actuator ($160.00) to cure the problem because I don't know which one is causing the problem. Jerry, at Boatmate, says its a crap shoot and I can kind of agree. Any thoughts???? Jacked both sides up and is fine right now.
