Brake Pads Disintegrating
-
Thanks Bernard, I’m pretty gentle with the brakes, so the previous owner must have gotten them hot probably more than once.
Good information from your source, but there is a whole bunch of these pads out there in the same condition as mine.
-
If this is a systemic issue, it wouldn’t be just an RV or even a specific converter issue would it? Wouldn’t it be a Prevost issue?
If so, would a call to them be advisable to see if they’re seeing anything out there even from their transport customers?

We now have seen this on several coaches and I have a couple of concerns. The first is as a braking issue its importance is significant and yet I haven’t seen any notices or service bulletins or recalls to make us aware of the issue, its cause or how to inspect for it.
I am also concerned because this cannot be exclusive to Prevost. And yet with all the trucks, commercial seated buses, large RVs and other vehicles running similar if not identical brake systems or components we aren’t hearing anything about this except from our members.
Has anyone with this problem contacted Prevost service, with photos and asked for further information. If not, I will because I have a brake pad as shown and will see if Prevost has information.
This is serious.

I sent an email with photos to Mr.Gagne who is in charge of customer service for all of Prevost. I hope we get a response.

Thanks

Stuck caliper slide pins are a fairly common issue on low use coaches, like ours. Stuck slide pins can and will cause this issue. The brakes on seated coaches typically get a lot more exercise.

I’ve followed this discussion from the begining . Took delivery 4/17 of 2006 H3-45 Marathon in Florida 60,000 miles on the clock . Drove it to Southern California , braking performance was poor. There were indications of less than full pad contact on all disc surfaces , light rust showing on perimeter faces of rotors. Putting the Coach in the air , pulling all 6 corners off, doing a midlife reset of the chassis . All 6 pairs of pads showed as much or worse degradation as any of the above pictures. Pads had 75% life remaining. Disc’s were flawless .Zero heat issues . I’ve owned & driven enough big truck miles , owned , driven & maintained 6 bus conversions over 45 years. This in my world is NOT heat related
Lack of use, high humidity regions , driving in wet conditions, may all be contributing to this.
This is a brake pad failure. Not a overheat failure.

We don’t have a large enough amount of information, but so far I am not seeing this type of disintegration on Meritor brakes and of the ones with disintegrated pads it appears to be exclusively Knorr-Bremse brakes.
I am hoping to get a good response from Prevost. If I wasn’t so damn lazy I would pull all my wheels and inspect mine more completely, but when I heard of this issue initially what little I could see looked good so at this point I don’t think we can say for sure the cause or extent of the problem.

OK, pulled and replaced all axles brakes on my coach 1995…all appeared original….No signs of abnormal wear or failure….So from what I am seeing it is all related to type of brakes….
-
No issues with my pads. They look like new.

Are those East Tennessee shoes?
-
We don’t wear shoes in E TN.

Jon would love the luxury of shoes, especially in the winter, but he is unable to afford them due to not receiving his share of the dues money….
-
I’m glad someone recognizes my plight. Tom sure doesn’t.

I have not had a response from Prevost. As soon as I get one, if I get one I will post it here.
I hope this is taken as seriously as I think it should be because if it is widespread as it appears it might be our brakes are compromised. If this problem is being noted on our coaches I am wondering if seated coaches are experiencing the same problems, and if so that is very much a concern.
