Sticking pedals

[dave364634]

On my 944 sometimes the clutch pedal doesn't return properly. It comes back far enough to engage drive, but I have to lift up the pedal the rest of the way with my foot.

Please tell me this is nothing to do with the cover plate diapram springs.



Also sometimes the accelerater pedal sticks at wot. I'm guessing this is the cable as I've sprayed the tb with silicone grease.

Check clutch fluid, sticking pedal is often first sign that it has gotten a bit too low....

when mine did that last year it was the slave cylinder. We ended up replacing both master and slave plus the hoses, as the fluid was apparently in a fairly nasty state and the hose was also shot.

Ok here's my best guess:

Clutch - likely to be one of two issues either:
A. One of cylinders is leaking internally and not holding hydraulic pressure, simple to change and bleed. Could also be a compressed/ damaged clutch flexi line just above the master cylinder.
B. the clutch release bearing is catching on the release bearing sleeve, there is a simple fix for this involving a USB flexi camera and a syringe full of grease.

Throttle - likely to be either frayed throttle cable inner catching on the outer but only at full stretch = WOT, easy fix to fit new cable. Other option, = damaged or altered drivers floor, caused by a jack or hydraulic lift. If the pedal can't hinge properly it won't return.

All four of the above I've experienced myself hence I know how to fix them !

My clutch pedal used to do this, has the car still got the original clutch? the original design had a rubber doughnut instead of springs as it gets old the rubber gets hard it does not flex and return to its position without the gentle help of lifting the pedal.

Do you find the clutch heavy?

New clutch and all will be sweet!

Can't help with the throttle pedal, but would assume it has stretched or news lubricating at the throttle cam.

As Chrisg has already said the accelerator is likely to be caused by a slightly deformed floor panel by incorrect jack. It's very common and the fix is to place a thick piece of carpet or towel at the base of the accelerator and hit it with a lump hammer.

Seriously

Oh... that's interesting. I think I might have the same problem! I thought it was just getting stuck on the car mat. Hmmm.... let us know how you get on.

One other thing to look at is the shaft that the throttle pedal pivots on. The pedal is held in place by a little circlip. When I refitted mine in the summer after removing the soundproofing, the pedal was a bit sticky until i'd fiddled a bit with the pedal.
