RV particulars: 2002 Winnebago Adventurer 32V – Workhorse W-20 chassis
Driveline (Engine, Transmission): Chevy 8.1L, Allison 1000
Miles: 20,155
Year: 2002
Break Down Description: (You can add any description of the problem here that you think would help others in understanding the situation and problem.)
Symptoms: RV began pulling to the right. We could smell what we thought was a burning electrical odor. When the brakes were applied, the MH pulled sharply to the left
Effect: We pulled off of the road at the earliest opportunity and called our road service (Coach-net) We advised not to drive further. (We were told later, that a wheel fire has resulted from similar incidence.)
Cause: Poorly designed brakes system. This Bosch ZOTS system, manufactured prior to October 2001, was used by many MH chassis manufacturers. I understand that an International chassis with this system was used on some school buses.
Outcome: Although only the brakes on one wheel locked up, the calipers, slides, and pads were replaced on all wheels. New pin kits were used. The right-front rotor was replaced.
Here is a link to a discussion of a National Highway Transportation Safety Administration investigation of these brakes.
