WORKHORSE BRAKE FAILURE On February 7/08 we left Lazy Days in Seffner, FL, drove North about 55 miles to our destination - an RV park in Port Richey, FL. We drive a 2004 Pace Arrow 37C towing a Malibu Maxx with a Brake Buddy. A few miles before our destination we started smelling something (smelled like melting plastic to me), wern't sure if it was something outside or coming from the coach. A couple of miles later ABS light came on and brakes went to the floor. We managed to get into the park by pumping brakes. Diagnosis was left rear caliper locked up, causing master cylinder fluid to boil over onto radiator, abs sensor melted, heat caused damage to hoses, pads,wheel bearings, rotors and differential fluids. All was replaced on both rear.
This coach had only 22,000 miles on a Workhorse 22 chassis. Searches on this and other forums show this to be a serious problem and there is an open investigation by NHTSA. If you have had a similar problem, please report it.
