1985FC Air pressure loss

[maureyroad]

When i take off the parking brake the air pressure drops from 125psi to
below 75. If i put the parking brake back on the pressure will build
back up. Any ideas what is wrong?

Dan:

Have some one release the spring break while you listen for air escaping at
the rear of the Coach just behind the drive tires. Sounds like you have a
ruptured spring break air chamber. Also is air escaping at the spring break
release valve on the dash?

Sounds like a park brake switch or more likely a rear spring brake
canister, Do not try to take that spring apart. It may hurt ya.
