Air System
leakage check
With the air system fully charged and the parking brake valve in the “release” position, coat the exhaust
port and around the valve corner of the SR-1 with a soap solution. Slight leakage is permitted.
If the SR-1 does not function properly, or if leakage if excessive, Bendix recommends that you replace it
with a new or remanufactured valve. If this is not possible, the valve can be repaired using a rebuild kit
available from the Gillig Parts Dept at (800) 735-1500.SR-1 Removal
