P30 brake pedal staying down	Bob	2-18-05
Hi. Ive got a 1986 southwind 24 ft motorhome with a 454 Hydro-boost brake system. The other day when I drove it, I noticed that the brake pedal was staying in the down position, and slightly applying the brakes.(I could feel the slight drag) I can manually put my foot under the pedal and bring it back up and it seems fine, but stays down the next time its pressed. The brakes have always felt fine, and for this to happen all of a sudden, not gradually seems strange. Im thinking booster, because the PS pump is providing pressure for the power steering and the brake pressure. What am I missing? possibly just a vac hose? any help is appreciated....

What is the price on the hydroboost brake system on a 1985' model holiday rambler? It is a chevrolet drive train w/ a 454ci engine.

The brake pedal intermittenly stays down on my 1999 p30 motor home. It can be pulled up with resistance. Any idea where to start?

The problem with my 1999 P-30 Chevy motorhome was the rod boot on the hydrobooster was out of place and allowed road grime, etc. to cause excessive friction and held the rod down or out energizing the brake. The rod was cleaned and boot repositioned to solve this issue.
