    Steve,

    Your steer and drive brake chambers are pretty standard if they are the Rockwell type disc (steers) and drum (drives). #30 on the front, and #30-36 combos on the drive. Check your local truck parts houses. Pretty cheap and all you have to do is cut the push rod to length.

    I think the tags are a #16-24 which is difficult if not impossible to find, but relatively cheap if you get a #24 piggyback with a #16 service. Surf the internet and you will learn what I mean.

    I haven’t bought that type of chambers lately but the prices over the counter from the truck parts houses compared to Prevost is close to a full tank of fuel difference in dollars.

    When I installed all new brake chambers, couldn’t find the spec 16/24 for the tag. So I put 30/30 on there instead. More service brake power on the tag, and more brake clamping in parking brake mode. That means all three axles now have 30 sized brake chambers in service brake mode. Some questions you might have about putting these 30/30s on the tag: Will the tag wheels lock up in low traction situations – not if your ABS is working. Will the larger bolt pattern of the 30s mount to the original bracket – yes, the bracket was designed to accommodate both bolt patterns. Will the larger diameter of the 30s clear the tag air spring/bag – yes, it is closer but does not rub.

    Another thing while you are in there, make sure your calipers are not stuck to the slide pins. All of my pins were corroded, and one of them was so stuck I had to cut it into three pieces with a die grinder to get it out. Prevost has them, but shop it for price. And of course look at the friction material on the pads. And be sure to shop the pads.

    I’ve always felt that we have lousy brakes, but don’t know what else to do about it. The Porsche prolly screws up my bias.

    I do not believe the tag axle brakes have ABS, just the drive.

    Thanks for the information guys, we plan on getting the brake chambers from a truck supply. We will check those brake parts too while we’re in there. Dan, thanks for the info on the other cans, if we can’t pick up the standard ones the 30’s may be the way!

    Hey Jerry!!

    I was getting a ton of oil in my air. The bus only has 78,000 miles on it. I’m not sure why the blow by but I’m sure some of the guys on here could tell us what causes this. I would guess just because it’s mine!!

    Thanks Steve, I’ll watch for that. Must have been rings in the compressor bad.

    Central States Coach Parts 847-364-4788 Elk Grove Village, Illinois.

    December 2012, $156.47 does two calipers – one axle.

    At the time, Prevost was higher than that for one caliper.

    Prevost part 62-1371 = Central States CFD – 268. Be vintage sensitive.

    Prevost on common parts is less expensive than other jobers. They run specials like windshields for $180 delivered. I think the brake pads for the tags/steer were 234$ per axle (2 wheels) and come with hardware and special little adapter to back pistons off. Shipping inclused is a factor also. Usuallt 2 days or less. Less expensive and correct is prob what I should have said. Bob

    Steve, you are aware that there is a filter on the air system and a ‘wet tank”, both of which need to be serviced/replaced on a regular basis.

    Joel ,

    I am aware of that, not because I’m so smart, Jeff Rowe showed them to me when my coach was on the lift!!

    I’m still impressed that you have 7,100 hours on your genny and it was running like a top!

    I want the same service out of ours too!

    Safe travels,

    Mr. Mark G.

    Mr.Mark,

    I have a buddy who is a driller. He says he has the same generators we use that have 35,000 to 40,000 hours on them. I figured if I ran my generator every hour I was out in my coach I would be 82 years old before I hit 35,000 hours!!!

    Steve.

    P.S. Just remember, they put A-Class generators even in B-Class Libertys !!!!
