Brakes and Drum part numbers for Lxi - cvaughn - 06-05-2013 20:39
I am working on replacing Brakes and Drums on my 1999 Lxi. I was wondering if anyone had part numbers. I would appreciate any help. I will have updates in a few weeks of research.

Charlie,
I'm running a commercial grade brake lining: Abex EX4725E2SB. (Eaton ES2 16.5x6"). They also make a quite lining: Abex EL4725E2SB.
Brake Drums: 3600AX (tag); WEB65607B (16.5x6")

Do you have a PN for the drive Brake Drums?

If you ever wonder how long brakes will last on your Wanderlodge, I may be able to help. I purchased my coach in Nov. 2004. Milage 90,000.
Last spring when I returned from Flordia about 170,000 miles, I noticed the parking brake would no longer hold on slopes>4%. After checking rear shoes, about 50% remaining, decided to change parking brake cans as springs do wear out over time and the pancake had never been changed. Changed to 30/30 Parking brake with 2.5" stroke. I measured the stroke on the old ones to may sure someone had not installed the newer 3" stroke models. Did not help the problem at all. Next I changed shoes. I confirmed shoe part numbers with David. The old shoes and drums still looked OK. The drums had some heat checks but I have seen much worse. New shoes still did not solve the problem. New drums solved the problem. The old drums were not scored or grooved where the shoe contacted. They were not cracked. I replaced front shoes also. They were worn out. I don't think the PO ever did any brake work on the coach. So I hope this may help you.
Front and tag axle shoe David's Part number for Eaton worked for Meritor crossover. Eaton 819762 The shoe is a double web 6x16.5"
Front and tag axle drums Webb 65166
Drive axle shoes Meritor XK 312476E
Drive Axle Drums Webb 66854B
Please note that cheaper parts are available. The E on the brake shoe part number stands for Extreme Service. The shoes with a part number ending with E or ES are Transit Rated for the 23500 lb axle.
The B on the Drum part number stands for Balanced.

Thanks Charlie, That's great information.
I recently replaced my drive axle brake chambers. The originals were piston style chambers MGM part number: 4131213. MGM told me that this part number has been superseded by MJS3028ET051. At the time the new parts weren't immediately available so I went with a 3036 diaphragm style, MGM part number: 3532051. MGM verified for me that the service brake and the parking brake force of the new part (3532051) and my old part (4131213) were the same, both are 2.5" stroke. The new diaphragm chamber that I'm running is the same that's used by Prevost on their 45' XLII and H3 series buses. I tested the parking brake on an extremely steep slope and they work.
Folks, when replacing your chambers it's important to be sure that the new part has at least the same pounds-force for the service brakes and the parking brake as your original equipment.

Looks like I need to research more on the combination brake.
RE: Brakes and Drum part numbers for Lxi - cvaughn - 08-08-2013 16:24
I changed my combination service/park brake to a 3036 diaphram type. It seems to hold better. I would recommend the three inch piston style if you can find one. They may be made of unobtainium, as I could not find one. The three inch reportedly holds better with drums at 500 deg. F. I guess the drums expand so much the extra 1/2" stroke helps hold the park brake.
