weird clutch pedal feel

[slpin]

my clutch pedal, when i step on it, makes alot of noise
also, it engages at the near bottom.
and when i step on it, instead of a smooth feel, it feels rough, like, it moves easier, then harder, then easier, etc etc

any idea?
its a 99 PSD with ZF

[slpin]

anyone have any ideas?
it does it when the car is on or off, so i know it is linkage, but which part?

[slpin]

the noise comes from under the car, so it is not the clutch pedal thing inside the car.

so i am guessing it is the fork, it makes the pedal operation not that smooth... how do i fix it?

I am not sure but maybe someone will be along shortly that can give ya a hand.

[slpin]

thanks!
the clutch engages near the bottom, about an inch or so off the floor, is that correct?
also, if i move the pedal slowly down, it will make a pop at a certain spot, and when i release it slowly up, it will make a pop at a different certain spot...

[Logan]

Nah, should be smooth all the way, you have checked your fluid levels and made sure of no leaks right. If it is the linkage, I would not know where to begin, but I am sure someone will. I just sold my 2000 6spd, never had any problems out of it. Mine would start to engage at about a quarter the way down, maybe you have a bad booster? I dunno.

[slpin]

fluids are good, and at the top line.
when you say quarter of the way, like quarter of the way from the floor, or from the top?

thanks for your reply!

[Logan]

Quarter of the way from the top, then you could feel it get more and more until you hit the floor. And no problem man, thats what we are here for. Is this a new truck, or new to you I should say? With the weak pedal, I am thinking about the booster maybe going bad, but not sure about the noise.

[slpin]

my apologies, i must have mis-stated myself

mine starts to get harder around 1/4 from the top too, what i meant to say was, the clutch is completely disengaged when fully depressed, and then when i let off about 1/4, it starts to engage, fully engage around half way.
the clutch is nice and firm, with normal increasing effort/stiffness.
so it sounds like it is working properly - well... except for the noise and the un-smoothness

this is a new to me truck.


the last owner took off the trailer brakes, but left the rear plugs on. does the truck have its own trailer wiring harness? i have a plug at the bottom of the dash, kind of near where my right knee would be. small rectangular plug, held on by two screws on the metal frame... could that be for trailer wiring? or do i have to hunt for it before i coudl plug in a trailer brake controller?

[Logan]

That sounds like it would be the wiring, if there is not a controler there for a brake, should be able to put one in right there. Yeah, not sure what the noise is, sorry I could not help ya any more, but maybe one of the techs will be along in a bit and see this. And welcome aboard if you have not been welcomed yet.

If you get a chance, put your truck info in your signature and where you are from, it will help us help you later on.
