Hi Guys
Working on a Clark GCX50. Can't get pressure on the inching side. Tried bleeding from the inching valve up both with a gravity feed and a pressure feed (as per the manual). No air in the crossover valve and a new master (suspecting a defect). The service brake side is good.

This is the annoying system with two masters behind the steering hoses and disk brakes. The service brake master feeds the crossover valve which feeds a slave on a hydraulic booster which actuates a second master to actuate the disk brakes. It has two fluid reservoirs. One in the dash and one next to the engine. It has a Perkins LPG if I remember correctly.

Any help/ideas would be great. Can post more info on machine if needed. Thank you.
