P 30 Brake Failure Sam Tayman 8-27-08  
I too am having the same brake failure problem with my 1998 P-30 35' Class A Pace Arrow. I have disc brakes on both the front and rear with shoes on the tag axle. It has happened 4 times. Every time it has been after the coach has been unused for 2 or more months. Also it has happened within 1 hour from home. My most recent case, last Monday, happened when I was in heavy stop and go traffic. The air temp was a little over 90. I thought maybe the heat in the engine compartment had over heated the master cylinder. Could this be possible?

My question about the calipers is do they need to be replaced if they are rusted or can they be cleaned? Also I have been told to make sure I replace the brake hoses. Do you agree?

Any help or suggestions are appreciated.

Hello Sam
i would like to know if the brake fluid has been changed "ever" old fluid absorbs water---and will boil easier---also---yes if your rv sits---the calipers "will stick" also if the hoses--collapse internally---the calipers will stick-
are you losing pedal---or MH just wont stop---
Ill be gone next 2 days---NO computer

The fluid has not been changed. The pedal goes all the way to the floor

Hello!
Any idea of how to get the disc of the axel?
My Elandan 1989 is so rusty so I have to take the disc of, but how and where can I order new?
