Default Clutch will not disengage '02 WRX

I am at my wits end with this freaking car. I have been having clutch problems with this car for months now and no one can give me a straight answer on what is wrong with this car.

My stock clutch had gone out so I replaced it with a Spec Stage 2 Kevlar Clutch and had the flywheel swapped out for a Clutchmaster light weight.

I started developing issues with the peddle not coming back all the way and major slipping issues.

The other day is when it just stopped working all to together.

Pulled away from the tolls at the DelMemBr went to shift into the third and the peddle stuck right to the floor.

Thinking that the hydraulics were messed up I replaced the Master and Slave cylinders. Nothing. Car still wont go into gear. I am losing my mind here people I am seriously considering junking this car, that is how much it is pissing me off.

What year? On my phone, cant see..

Push or pull type clutch...

Ive herd of the push type cracking the clutch fork in half...

Are you able to see clutch fork movement? And are you able to move the clutch fork by hand at all (indicating a cracked fork if you get considerable movement)

This ^^ Get under the hood and check if your pedal system is working the way it should. Have a partner depress the clutch and look to see if the slave cylinder is expanding and pushing the clutch rod coming out of the tranny.

had the same thing happen to me, with that clutchmasters lightweight flywheel. one of the bolts that hold the metal center section into the aluminum of the flywheel had broken, causing the bolt to wedge itself between the disk and flywheel. clutch wouldnt disengage.

I have tried moving the clutch fork by hand and there is no significant movement. I had my wife help me bleed the system and we started to get good pressure in the pedal but it still wouldn't disengage. I thought it would be a hydraulic issue because the peddle would just get sucked to the floor. There was absolutely no pressure in the peddle when the clutch stopped working.

@Juggalo did you have to replace anything or take the trans out to fix it? I don't have access to the proper tools to drop a trans. And I'd rather not spend more money fixing someone else's mistakes, unfortunately the shops around me are a bunch of jack offs and won't warranty labor on installation of aftermarket parts. That pretty much tells me that they have free reign over what they do in my car. I would hope people weren't shady like that but you all know the kind of world we live in.

yes, when that bolt let go, it destroyed the clutch disk and damaged the center insert of the alum flywheel. i was still able to drive it but something wasnt right, bad pedal, bad engagement. had to pull everything apart. im lucky enough to have clutchmasters 5 miles from my house, they helped me out with replacing the damaged parts.

Does the clutch rod move or try to move when the pedal is pressed?

If it's leaning toward the firewall the rod is in the engaged position, likely your problem is still in the hydraulics.

If the clutch rod moves with the pedal press to nearly vertical with the firewall then the problem is likely with the clutch itself.

DOH




Wow I missed everything here... must have been THAT early...

Pedals stuck to the floor would lead me to think Master cylinder.. If you where getting pressure and it just failed, master/slave cylinders...

If the clutch fork ain't moving, my guess is you still have air in your hydraulic system somewhere... I have a couple of questions for you now.

Did you bench bleed your master cylinder before bolting it on the car?

What about the slave cylinder? If no on this; Did you have the slave cylinder unbolted from the car when bleeding the system?

When I did my clutch line a few weeks back, it took FOREVER to bleed the clutch system. I found out that the slave cylinder needs to sit level during the bleeding process to get ALL of the air out. After unbolting it from the car, a few more pumps got the last bubbles out and the pedal was solid! Give 'er a try

Thanks roadkill I will give that a try.

@Juggalo When that blot came loose, did it make a lot of noise because mine didn't when it failed. The peddle just got sucked straight to floor as if all of the pressure in the hydraulic system had went away.

no noise, pedal went straight to floor. ran fine up till that. i mistakenly replaced the master and slave for the concern.

Pulled the slave off when I got home and then discovered this.

From the link to the youtube video, it could possibly be the C clip that snaps onto the other side of the throwout bearing once it is seated into the pressure plate. Also, did you grease the input shaft of the tranny where the throwout bearing slides on?

Also, why in the world did you get a kevlar clutch? Any power mods down to your car to warrant such a clutch?

Open source tuned, TBE, STI intercooler.

I didn't install the clutch and the clutch was recommended to me by JSC Speed.

That's funny, my Exedy OEM is taking the solid 300+ I'm giving it... I've got about 10 more power mods than you...


It looks and sounds like the TOB came out of the clutch... regardless it's coming back out at this point... Sorry... once the TOB clips into the clutch, the fork shouldn't be moveable...

Live and learn I guess with the whole clutch thing. Unfortunately I'm stuck with it. Hopefully this will be a relatively painless fix. There a bunch of guys in the MAIC group willing to help drop the trans with me.
