2010 Monaco W22 Chassis; Brake Recall?

[phredsee]

I'm curious as to why the 2010 Monaco W22 Chassis is not involved in the brake recall or if there is even a problem with this model year? Are there different parts being used that aren't affected or has the recall not yet caught up?

[Bob (WA0MQE)]

On brand new chassis' I'd think Workhorse has changed to different or at least newer brake components that are not susceptible to the problems the older brakes have. I'd even think 2008 and 2009 were in this same category.

Soooooo..... Why can't the older m/h be fitted with the newer brake calipers? Had to ask. I'm sure DriVer can tell us why.

phredsee, The ZOHT Bosch pin slide hydraulic disk calipers that are on a 2010 chassis are no different than the calipers than I have which were replaced last year. There was nothing remarkable about those calipers other than the surface coating was changed for environmental reasons.

When the campaign launches, that's when I expect that we will see newly engineered calipers that will be incorporated into the new chassis builds that roll out of Union City. Until Bosch comes up with the new calipers we're still all of us on the same page.

In time to come if you have the old gen calipers, I expect that those will be up-fitted with the new calipers and you will receive a campaign letter to have your service center upgrade your calipers.

"The ZOHT Bosch pin slide hydraulic disk calipers that are on a 2010 chassis are no different than the calipers than I have which were replaced last year."

So the recall will be extended to the 2010 as well ?

Bob, I would like to think that as well however I don't believe that's the case. What is the difference is that all of those brakes are brand new and they would not have a tendency to exhibit the problems that we are seeing here in the 01 to 04 chassis because they don't have enough time on the job yet. Let them get water soaked and sit around for a few years and I expect that those problems will present in time.

Steamerman, Because they are not new, they're just brand new. If you get brand new calipers on your motorhome in the Interim, I expect they will perform just as well as those on a new chassis that come right off the line. What is difficult to put into perspective is that all those new problem free calipers may have to be replaced by the newly engineered units when they become available.

I expect that in time they will begin building new chassis with the updated caliper and also feed those into the parts system as well so the campaign can start moving toward resolution.

Steamerman, I would expect in my opinion that the recall will extend as far as it needs to go by VIN# because they will know which VIN# chassis will have the new calipers installed on it.

I was under the impression that a "Different" Bosch brake set-up was on new chassis. Mike, your statement leads me to believe that "ALL" WCC motorhome chassis, with the ZOHT Bosch pin slide brakes, are "Ticking Time Bombs" when it comes to braking performance. Did I miss somethding?

Fred, I wouldn't go as far as to believe that something is ticking away however In my opinion, all W series motorhome chassis with ZOHT brakes until other wise posted are subject to the campaign. That said there is a date range in the Interim Notice however I expect that to be somewhat fluid as the campaign progresses.

New calipers are not ticking time bombs. Those brakes will work very well for the next several years. I have a new set of old ZOHT brakes installed (18+ months ago) and they work great! I have written so much about maintenance that I don't want to start rehashing all of that here except to say again that flushing your brake fluid periodically will help keep your brake system healthy for an extended period of time. Even then ZOHT brakes found dissimilar to the re-engineered units I expect will have to be upgraded or repaired.

Once the campaign is completed on our motorhome chassis nothing will absolve us form having to flush our brake fluid every 2 years as recommended in the 2009 Chassis Guide. I expect that we will see that language in the owner's manuals going forward although I have not seen it at the moment.

Thanks for all the replies, at least I kind of know what to expect. Just noticed on the last trip that when I have to brake hard Monaco has a red light on the dash that lights, I'm sure indicating a hard brake condition. Being aware of the braking situation, the grade brake does a good job and I use it all the time.

phredsee, Is this light located in the instrument panel? If so Monaco didn't put it there. Other lights that may be installed by the coach builder may include, antenna up and jacks down lights and possibly others. I have not seen where a hard braking type lamp would be provided by the OEM.

As you go forward with the ownership of your new motorhome there are some routine maintenance items that need to be accomplished and those are all detailed in the 2009 Chassis Guide and a link is provided here so that you can get there to download your own. You will need to register your motorhome in the "My Motorhome" section and be required to login. From there look for the Guide in parts/publications and you can download it for FREE. The thing is pretty big!




More than a 1/2" thick, I went and had it printed at the Depot, double sided.

Consider if you will flushing your brake fluid sometime in 2011 and this will I expect will help you in the long run prevent buildup of moisture in your hydraulic brake system.



The Chassis Guide is a large PDF file and you should have a copy of the Adobe Acrobat Reader installed on your system to view the document.

See.... All this information is the reason we can't be without our DriVer on the forum!

My thoughts eezzzzackly Mr Streamerman!
