There has been at least three instances of similar brake problems involving the Workhorse chassis posted on the forum this week. The problem involves the brakes locking on one or more wheels. Since I made my post, I’ve done some digging and have become aware that the problem is not unique to Workhorse and the Office of Defects Investigation of the National Highway Traffic Safety Administration is currently investigating the problem.
Senior Investigator Sonny Murianka would appreciate relevant information if you have had a similar braking instance. He would like a short narrative, make, model and VIN. Although he didn’t say, I would imagine he would find useful the name, address, and/or phone number of the service center that handled your problem. He can be reached via email at

I sure didn't mean to be contradictory. My knowledge of the problem started as a Workhorse problem; we have a Workhorse chassis. Knowing that Workhorse does not actually manufacture the breaks, I did some digging on the Internet and became aware that the problem is not limited to Workhorse. I do not feel free to discuss the particulars on the forum. I will say that the brakes on our chassis were a Bosch ZOTZ system manufacutred prior to October, 2001. BTW, the date is stamped on the top of the calipers.
If you send me an email, I will give you some additonal information. (That statement could create a number of emails. If it does, I'll answer as quickly as I can.)
The purpose of this thread was to ask anyone who has had a problem with brakes suddenly pulling while driving to notify Mr. Murianka. The real danger, as I understand it, is a fire.
I just took my RV into the factory service center. The problems did not include brakes. However, the lady who did the paperwork asked me about the brakes and indicated that there had been some problems. What has been posted here suggests that each of us need to look into this.
I am going to call the service center when I get off the computer and will share any information I receive. If anyone else finds something we need to know, I would appreciate it being added to this thread. I will bookmark and keep checking.
