Clutch pedal vibration

[rico]

Hi,

Recently my clutch pedal has started vibrating when I push it in. It does not vibrate when fully out or fully in but only as you start to push the pedal in. Clutch seems to be working fine, not slipping etc.

Anybody know what the cause is? Do I need to adjust the pedal or something?

Cheers.

at a guess i would say the throw out bearing is going

Yeah release bearings going on its way and your feeling the pressure plate fingers . . . You feel my pressure plate fingers all the time with hyper 6 puck

...has anyone thought of run-out in the flywheel or pressure plate from heat sink or over heating? or am i just way too old skool? ;D

You would feel fly wheel run out with pedal right in though wouldnt you ? He doesnt feel it with pedal in

good point....didnt think hard enuf lol , but if he has to replace thrust bearing then do the workz

Yeah hard go whole clutch kit while your in there . . . Might as well jam a new rear crank seal in too

[Guest vf20/21bg5]

...yeah and a new turbo and twisted setup ;D

Check & make sure your pedal box is bolted in. This might sound OTT but i went to drive to work bout 6 months ago & the one of the bolts had completely worked loose & dropped out!

If you have to go in there to sort issue THIS is what I would do minimum,also a flywheel resurface,

++1 you would have to

Hey, thanks for all the suggestions. I had a feeling it was going to be a major . As suggested will get the whole clutch kit and fly wheel resurfaced.

Is it going to be doing any harm continuing to drive it in the meantime while I get parts sorted etc?

Oh yeah I forgot to mention . . Its a must when you do a new clutch to re surface fly wheel . . Bnt is 50 I think for re surface . . . . And is your release bearing noisy when foot is right off the clutch ? ? It should be all right for a while unless its crazy noisy . . . Normally when they get noisy they make noise when pedal out and stops when pedals in . . . . . The worst that can happen is the release bearing could seize . . . Then you will really hear it

It doesn't make any noise at all, just the vibration. From what I've read online whilst searching it seems that normally you can hear a 'chatter' when the bearings on its way out so maybe mine is just starting to go.

Anyone bought one of the kits off trademe? http://www.trademe.co.nz/Browse/Listing.aspx?id=371314262

It seems you can get either 225mm or 230mm, anyone know whats the best kit for a 97 BG5 gtb?

Cheers.

Had a similar sounding issue with my last V7 Sti, the clutch peddle felt a little fuzzy/buzzy when coming in and out haha Hard to explain but yeah sounds similar.

I did 25,000kms with it and didn't have any issues but I did notice that the issue came and went and wasn't there the whole time. I thought it may have had something to do with the fact my clutch fluid tank thing didn't have a heat shield on it and was exposed to heat from the Siamese downpipe

i no its a bit late but i had the same thing in my old gtx every thing was new and flywheel skimmed, turns out we bent some of the pressure plate fingers, which isnt a biggy if you can put up with it.

it was mint the whole time i had it until the new owner tryed to drift it and hit a tree lol :

Got it sorted. Wreckers had a 2 week old clutch kit that they had installed then bought back when the car they installed it on was written off. So got basically new clutch fully installed for $500 so pretty happy with that. Feels like a new car to drive, so smooth. But do hear a slight rattle when idling which haven't had a chance to look into yet
