Brakes and Drum part numbers for Lxi

[davidbrady]

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 MGM told me that this part number has been superseded by MJS3028ET051.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.
