Hello.
COMBILIFT C4000 (25405) 09/2014 year.
Foot brake problem. At a standstill, the combilift is driving when the brake is depressed at the max. While driving, the brake does not brake as it should be weak, the operator makes comments.
The handbrake (red fungus on the board) works and stops the combilift in place. Brakes on engines checked, "rotary inch valve" replaced. New filters and hydraulic oil.
Should there be pressure at the "Ps" output? After connecting the pressure gauges, there is no pressure at the "rotary inch valve" connections. Oil flows, but you can stop it leaking with your finger.
Anyone have any idea what could be wrong with these brakes?
