I have a pneumatic tire Clark forklift with no brakes. Both the brake and inching pedal go to the floor. I opened the bleeders on the front of the forklift, power bled the system and got nothing to come out. The small tank in the front/middle has a bleeder, that opened and bled nice, then there was a heavy leak behind the left tire. I assume there is some sort of wheel cylinder behind the tire, drum, etc. What on earth do they look like? Part numbers? Anything? I don't want to tear into it without having the part to swap in. I figure I would do both sides while I'm in there. I have an operators manual, which is about 200 pages, but does NOT show a wheel cylinder in the brake system diagrams.

They are leaking at the bleeder extension that sticks up from the axle, aiming forward. Clever design, but it would have been great if they had done 3/16" instead of 1/8"
if it leaks at ftgs sometimes you get wrong wheel cylinders they could be missing brass insert in the hole for the line
Not hesitant. That's where I bought the master and wheel cylinders. The shoes were not oil soaked. The hubs had, from what I could tell, original grease from 1967. Inner seals from the transaxle seemed to be working just fine, so no saturated or brake shoe contamination. The two dealers I have spoken to do not have that 1/8" brake tube. I was going to make one out of what I have in stock and see if that works. If not, I can make more calls.
Why are you so hesitant to call the Clark dealer to get the parts. You don't need part numbers just model, serial # and description.
If the hubs were all greasy then the brake shoes are also oil soaked. You may think that you can clean them but once they get hot the oil will ooze out. The shoes are very inexpensive. Just replace them! Forklift brake shoes NEVER wear out. they only get oil soaked.
The weather finally broke and I have had a little time to work on it. The hubs and final drives come out very easily and required very little persuasion. The shoes looked fine and the wheel cylinders were leaking. I was able to source the wheel cylinders quite easily via a forklift outfit. I bought both master cylinders and both wheel cylinders just to finish the job and make sure no further issues. It took more time to degrease and wash the hubs than to do anything else. I am having an issue with the 1/8" tubing that extends the bleeders to the wheel cylinders inside of the final drive housing. It leaks and needs to be replaced. 1/8" tubing is hard to flare and find.
Easy peasy if you're a young guy done lots on the road many years ago. Have at er
Just call the local Clark dealer with the model and serial #. Tell them that you want to do a complete brake job. They will price up all of the parts that you will need. make sure they include the oil seals. The prices should be relatively cheap.
call your local clark dealer and tell him what you need , no one knows what you will need to order
I have lots of heavy machinery experience, I just can't find a part number to order. The job doesn't scare me, but I need to know what to order so that I can get this all done in one shot.
Major repair good luck with that :)
wheel cylinders are in differential in brake hub this job is not for the timid,your master cylinder maybe leak look at both of them first
