Can anyone give me a cure to this problem, I have seen various posts in the past covering this problem but not seen a definate
cure it only sticks when accelerating hard in 1st 2nd and sticks at about half way up and needs my toe to unstick it. 97 WRX STI

thanks in advance

 

hi bud, i seem to have the same problem sometimes in my 96, turbo 2000, very strange!!!!

 

I have EXACTLY the same problem with my STi-3 box !! clutch still works ok... must be a worn linkage ?

 

I have a 96 wrx and the pedal sticks on it most of the time. I took a quick look at it and it's nothing to do with the clutch itself or the linkages (I removed the intercooler to take a look). I think it's the spring thats inside the car on the clutch pedal. It must go soft but it's looks a nightmare to change. Anybody and ideas, surely someone has fixed this problem before!!!!

Thanks

same sort of thing here as well on a 93WRX but not all the time most strange

 

OK guys its a very simple fix.Remove the intercooler and look at the clutch release arm there "should" be a spring between the arm and a small bracket just underneath the throttle housing.
What normally happens is the spring breaks and then when you accelerate the clutch pedal sinks tho the floor.

Heres the part number 30456AA030 any Subaru dealer will be able to supply one of those

Thanks for the info steve I had the intercooler off today and your right no spring so ill have to go searching monday round the scoob dealers hope they dont have to order it

cheers mate

 

Steve,
I have checked the spring and it looks ok but maybe it's gone soft so I will order one and see if that cures it and I will post the results.

I fitted a new spring and has made no difference. I think there are 2 problems the first one is for people whose pedal sticks under hard acceleration and I reckon it's the spring under the intercooler.

The second problem is the clutch pedal sticking most of the time and I reckon the cause is the spring inside the car on the clutch pedal.. Has anyone ever changed the spring inside the car???

i agree david as my spring under the intercooler is fine but i still get the problem.

 

The springs do wear and lose their tension. As Steve said, its almost always this that causes the problem.

 

Ok the other thing to check is that your clutch pedal freeplay is correct,you should only have approx 10mm of freeplay at the top of the pedal.Adjustment is carried out by loosening the 12mm locknut on the clutch master cylinder pushrod and then turning the rod itself.

Hope this is of help guys

Steve
