Ridewell down in the front.

Ridewell down in the front.
I had a problem simular this. I had to replace the Bendix DC4
valve. This valve is located on the drivers side inside frame rail
just above the back-front air bag. It's inline with the air-
compressor, located before the first air tank. The exhaust runs
under the dc4 valve and over the front airbags.
I had a leak in the flex pipe that caused extreme heat into the area,
destroying the *O* ring in the DC-4 valve. (also destroyed an air-bag)
This is a b*t*h to get to.
With this valve malfuntioning, the front of the coach would'nt rise
to the occasion. However the brakes aired up as did the rear air-
bags.

Hope this is of some help.
