pedal thru the floor

Just got my new clutchjob back and noticed that you basically have to shove the clutch pedal thru the floor to shift and pullout. Is this normal?
Should it go away the more its pumped? I've read a lot on here about bleeding the clutch and seems like theres two camp, one for and one against.

No... not at all.

Yeah, I've noticed... no idea why... however, in your particular case (or any other), if the hydraulics weren't opened up somehow, then they didn't get air in them, and "bleeding" wouldn't be an issue, regardless. I'd recommend looking elsewhere for the cause.

When you changed it out, did you put in a new pilot bearing/bushing?

Which of these 2 ways did you put the throwout on the fork?



Putting it together the "wrong" way will use up about 1/3 to ½ of the available pedal travel in just taking up the unneccessary "play" that it installs into the system; IOW, no clutch releasing action even BEGINS to occur, until the pedal is near halfway down.

Re: pedal thru the floor

Having just installed my clutch and 5-speed it should feel pretty hard 3/4 of the way down. if you barely press it, it should push back a little. If you are still in doubt, find someone close to you with one on their car and see the difference.

Re: pedal thru the floor

I ended up taking to a shop and the mech told me that the throwout bearing was installed correct...he said that other T5's hes done usually take some time and lots of pumping the pedal to "adjust" in to the correct position. While doin the change, the guys did unbolt the slave and leave it hanging on the car, as far as I know, the hydraulics were not opened, but the slave piston did extend out all the way and was pushed back in for installation.
I do know that if I crack the fluid cylinder it spills out....didnt do that before the change. Do you think that when the slave piston was pushed back that it possibly got air in and pushed the fluid to the top and now has to drain back?

Re: pedal thru the floor

It's gotta be one of the two things listed above, the throwout bearing was installed wrong, or they did open the hydraulics and get air into the system.

I can't think of anything else it could be.

Then he screwed those up the same way too, somehow.

Shouldn't be like that.

Letting the slave hang doesn't cause that. Pushing the pedal when the slave is removed, and "popping" the rod out, might. For that reason I usually remove the rod from the pedal when I start the job and don't put it back until the slave cyl is fully re-installed, so that can't accidentally happen.

It'd be nice to know what he did wrong.
