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?

Hi Cian,
Yes you are correct the inch pedal will disengage the drive. If you need the truck to stop on a slope you can use the emergency brake, or alternatively you could get a switch fitted to the inch pedal to auto engage the brake (usually a 3 to 5 second delay allowed).

I have a Combilift c4000 with a brake issue. the park brake is working fine and the inching pedal will disengage the drive and stop the combilift, however if the inching pedal is engaged on a slope it will stop and then allow the machine to roll slowly while the inchinh pedal is still depressed. Anyone got any ideas? I am new to working on combilifts
hi tomason2 from what you are describing i would check the inching pedal lever has not slipped around on the shaft so loosen the the lever cap screw and make sure the shaft is all the way back clockwise and then put lpedal lever back on and tighten cap bolt i suspect the lever has slipped forward on the shaft and when you depress inching pedal the reason it still drives is that you are not getting full opening of the valve see how you go
hi richard
I know that this pedal will not stop in place, but why in other combilift, after pressing the brake and adding full acceleration, it does not go?
Hi,
The brake pedal you mention is not actually a brake pedal that applies brakes. It is call an inching pedal. What it does is stop the oil being pumped to drive the wheels. This allow the truck to slow down to a stop. Some trucks are fitted with a button below the inching pedal that will apply the brakes after a pre set no of seconds as you do not want the truck to suddently stop if carrying a high load.
This is explained in the manual that should be in the truck.
I hope this helps, but if you need additional help you can submit a support request via the combilift web site, www.combilift.com and just scroll to the bottom and select "Technical Support". There is no cost for this support and no login required.
Hope this helps
