Clutch Sticking to the floor

[hubz91talontsi]

My clutch likes to stick to the floor sometimes, and i was wondering what you guys think about it. Its not a big deal but sure does get annoying. Im thinking i need to bleed the clutch but im not sure how. Any hints or tips? thanks guys.

Either your slave or master clutch cylinders are done. Replace them both and bleed the lines correctly and everything will be fine again.

And here are the results for bleeding your clutch. There are a bunch of how-to's in here.

well the master and slave where just replaced so im going to guess i need to bleed it.

If it's sticking to the floor, make sure you have enough clutch fluid in the master cylinder (that it hasn't developed a leak somewhere and all leaked out), then bleed the line. If the fluid level is low, track down the leak BEFORE replacing your master and/or slave cylinder... I've seen one develop on the rubber line, and the owner of the car ended up shelling out pointlessly when he assumed it must be the slave seals dying.

As a side note, the reason that most mechanics recommend replacing both is that they tend to be about the same age... so it can be assumed that the seals on both will start to die at the same time. Also, it's more profitable... more worked hours, more part markup margin. The master and slave cylinders share no parts that need to be removed to work on the other, so it does NOT save any time to do them both at once.
Currently, my clutch master cylinder has outlasted *three* slave cylinders, and is showing NO sign of leaking.

where is the slave cylinder located? anyone have any pictures to make this easier =]

 

[No_Skillz]

It's the little cylinder underneath the car with an accordian-like rubber thingy coming out of it, and a rod coming out of that, and it pushes against a tab-like thingamabob dropping out of the transmission.

Scroll down to adjustments and familiarize yourself with adjustments and make sure ghost pedal is not your problem.

 

[hubz91talontsi]

Ghost Pedal thing isnt the problem it only happens when i hit the pedal and it doesnt get completly stuck to the floor i can bring it back up with my foot but it gets rather annoying doing it 10times in 15min

 

[No_Skillz]

I'm betting your engagement is really low too. If that's the case and engagement/pedal travel doesn't get lower an lower, there's air in the system. You're right on track with the bleed, and make sure you adjust the master right when you're done. That thing was a huge PITA for me.

 

[hubz91talontsi]

yeah im thinking there may be an air bubble in the hose i found the slave but it started raining so i packed everything up..save it till tomorrow i guess. thanks though guys for your help.

 

[hubz91talontsi]

bleeding and replacing all the fulid with new did not help, slave cylinder does not look new like the master does. Wondering if that is the problem may replace it tomorrow.

 

[hubz91talontsi]

starting to think it may be the ghost pedal i watched the clutch randomly drop to the floor once, after i changed the fluid it does not seem to do it as often

 

[meliketoball]

Crankwalking or extremo wear and tear of the thrust bearing is a sign of the clutch "sticking" the floor. Take left turns really hard to see if it'll stick the floor.

 

[hubz91talontsi]

can i do this with the car off? or do i need to turn it on?

 

[hubz91talontsi]

ok well i did both they clutch does not drop. i pulled forward? and back? im not sure if you have to be going a certain speed? that would make a little more sence but if thats the case ill try that tomorrow.

 

[Dagda]

you need to be driving to do the crankwalk test, as far as i know.

also, i had the exact same problem. had the slave and master put in, both brand new, by the guy who does most of Buschur's tranny work, and still it would stick to the floor. the problem was, the place where he was buying the parts was crap. the problem continued until i was talking to shep about it, and he said sometimes the mechanics/people will just buy a crappy master cylinder that doenst hold the fluid, so that it simply pushes through the seals on the internals.

so in my case, as was in yours, i had all new parts installed perfectly and bled well and it still happened, due to purchasing from the wrong companies.

hope that helps

[hubz91talontsi]

ok im a little confused now, how would i end up fixing this?

 

[No_Skillz]

You can't fix crankwalk. You will need a new motor. Don't worry about crankwalk yet. Please explain your bleed process.

 

[esoung]

probably need to replace a cv boot and cv joint. get it fixed immediately, eventually the clutch won't ever come up which will cause a disastrous while you're driving.

Same thing happened to me and I had a shredded clutch disc.

 

[1g_tsi_awd]

Same thing happened to me... Three tranny bolts were loose causing the tranny to become unmated to the engine. Simple fix. Check it out.

1) Check your hydraulic system. Master, slave cylinders, and the hydraulic lines; anything that is related all of that. Look for leaks and check the master cylinder fluid reservoir every time you drive.

2) Bleed your clutch and possibly adjust the clutch pedal.

3) Like what the other guys said, check for loose bolts that connect the engine to the transmission and how old is your clutch anyway? Was it slipping? Did it catch/grab good?

4) If all those pass, then you have to consider that your car may have crank walk.

clutch is perfect grabs fine, im not sure how old it is i just bought the car last week how would i adjust the clutch pedal? sounds like i got some work to do. =[

You have to pull your driver seat all the way back. (so you can fit. ) Then get a 12mm, 14mm wrench, vice grips or channel locks. Look for the clutch pedal and trail it up and you'll see something connected to the clutch pedal then trail that down and you'll see a metal rod connected to the master cylinder. After that trail that back to the clutch pedal and you'll see the metal rod threaded in to this blue/silver colored piece that is held on by a cotter pin.

The blue/silver colored piece that is held on by a cotter pin has a 14mm nut and right next to it is a 12mm to lock the master cylinder push rod so it won't move around (only pivot up and down.)

Get your 12 and 14 mm and break the lock nut connected to the blue/silver colored piece that is held on by a cotter pin. After you got that, you can use your vice or channel locks to twist the master cylinder push rod in or out.

If you twist in, the clutch will be grab earlier and if you twist it out it will more later. Play with its adjustment then see what happens.

P.S: If you are twisting it out, DO NOT TWIST ALL THE WAY because the push rod will thread all the way out and was a hassle for me because I bend the push rod and had to take the whole master cylinder assembly out and bleed/adjust everything over again. ( I have an ACT pressure plate with their infamous hardened centers.. )

Have fun!

haha im 6'5 i need to pull it back so i can fit now but im going to go try this later. Got in the car earlier today and my battery was dead and its been raining for days so i havent been able to spend much time barly got to bleed the clutch yesterday got about a 15min window where it stopped raining
