I have owned a 2001 Monterey (short - 33 foot Magnum air over hydraulic model, 3126B engine) since almost new and have never had any problems with the parking brake system. On a recent trip I found two occurrences where the dash air actuation switch somehow made its way to an intermediate position while underway - not fully in, or fully out. No air leaking could be heard, nor did I feel any strong braking action. However, burning brake smell told me the pads were engaging to some degree. Now the parking brake barely holds the coach. It actually creeps a bit while at idle. I have found the replacement dash switch online, but now it's time to adjust or replace the pads, and maybe other parts. I have done a number of searches on the forum and have learned the parking brake is a driveshaft "squeezing" type system, and can readily see it under the coach, but I haven't found part mfgr's name or numbers, or links to any drawings or maintenance instructions. Does anyone have any specifics on who made the parts for 2001 era Beavers? Might any manuals or maintenance procedures be available? I try to do as much maintenance on the coach as I can, but if this is too heavy duty a job, I'd like to know as much as possible before taking it somewhere for repairs.
