When I press the brake pedal it goes about 1/3 way down and then rock hard. I can stop the lift if I stand on it.

Check m/c res, main was full, inching was empty. I filled the inching no change. If I take the top off the main and press the pedal fluid shoots straight up about a foot out of the res. On the inching I have no resistance at all (other than the spring). It does disengage the drive but that's all. Also when looking into the inching res if I pump pedal, bubbles come out of the port in bottom of res.

I'm assuming a main m/c but with the inching being dry I'm not sure.
