Yale GLC060VXNVSE088:
brake pedal getting stuck slightly while using inching pedal

So I installed some wheel cylinder on a yale got called out today about forward and reverse delays right after using the inching pedal. Found a piece of wood smashed by the brake spring. My question is does that spring supposed to bring the pedal back up or just hold it there ? I also think maybe I should have adjusted the master shaft that attaches to the pedal?

I have a picture but cant upload for some reason

From the pictures you sent and what I have found as far as info on the inching system on this........there is no brake line going to a inching valve....there is a electronic brake sensor(transducer) that is mounted on the bottom of the master cylinder,this sends a signal to the Trans enable valve on the Trans control valve Assy on top of the Trans.
The casting where this valve is mounted has a number 5 cast into it,in your pictures it looks like this valve is leaking some as it looks all wet/grimy around the valve....it is possible that your valve may be sticking is why it is doing what it is doing.....

The Yale VX has that fancy electronically controlled transmission and you can adjust the brake/inching overlap time using the dash buttons and screen. Scroll the menu and it's there.

I work on a couple of these & kevins correct- a brake line runs to the inching valve & it is controlled by brake line pressure. Try applying the brakes hard a few times- then make sure the inching circuit is activated when the pedal is released, then, while the inch circuit is still activated while the brake pedal is at rest loosen a bleeder & check if there's residual pressure that bleeds off. Check this at the inching valve as the brakes always have about 7 lbs of residual.

If there's residual pressure then either you have a faulty master cyl or the adjustment for the master cyl push rod needs adjusting. There should be free play at the pedal surface for this reason.

If the pedal is at rest- can you manually pull the pedal more 'off'? If- after you've pulled the pedal 'off'- does the inching system work correctly? If so then maybe the issue is the wood bent something or the pedal pivot needs lubrication- just a thought

2nd thought- what was wrong w/ the wheel cyl? Did you disassemble to diagnose or just replace. Someone may have fill the master cyl w/ the wrong fluid & unless brake fluid is used the seals well swell & stop things from moving as they should. I've seen this a million times

Looks like the master cylinder has a pressure transducer mounted on it to monitor brake pressure and sends a signal to a transmission enable valve on the control valve on the transmission.....

Customer just bought the truck didn't want me to take out to take pictures customer thinks they jammed it in there on purpose. So what activates the inch pedal on this model?

Is a single pedal with a return spring on the horizontal support shaft..there is still a chunk of wood jammed against the spring and the push rod for the master cylinder has a scuff mark on it like it got hit with something and possibly bent a little as we'll as the Clevis on the rod looks spread apart a little.....

First time working on this type of yale I didn't see any cable to engage the inching pedal I have pictures but cant upload them

The spring is there to bring the brake pedal up fully to the rest position. The brake rod is adjusted to give 1/4 inch or so of play at the pedal so any residual pressure in the brake system can bleed off. Secondly I believe your unit has a cable which actuates the inching spool- make sure you have full engagement of trans & no by-pass what-so- ever when the pedal is in the up/rest position.

Sounds like the brake spring on the pedal shaft is binding a little after being jammed with the wood....
