I have a 50 PW, wrecker with a Vac Booster brake arrangement & a confusing array of hoses and brake lines. Does anyone have any idea how the Master cyl line ties into the booster, and then feed to the brake cylinders? For some reason the vac hose from the intake manifold goes to an AIR TANK mounted under the wrecker body and T's off to the booster. I don't recall booster systems having a tank. There is an identical tank located on the opposite side of the wrecker body which connects to an air compressor, mounted between the wrecker booms, that is driven from the PTO.
Is there any documentation available for the Booster system other than the Parts Manual.
All help and suggestions appreciated.
