      Ok, so i have bled this clutch foreverrrrrrrrrrr! Still sucking air from somewhere... it seems to me like the only place it would come in is from the plastic nipple on the top, or maybe not. I have no idea, but i dont have money to waste on a new one if thats not the issue.

      Started out that the car would not shift into gear at high rpm's, next it couldnt go into gear at all very well. now it wont go in gear at all.

      the only other thing that is in the equation is the nasty blue braided line that goes from the brake master, to the clutch master.

      Someone throw me some insight, so i can actually drive my corrado for once!

      sure its master cylinder? could be slave cylinder. is your brake fluid low? do you see where its leaking from? if yes, leaking externally you should be able to find culprit; if you see fluid down the firewall or inside floorboard, it could be master cylinder; if its internally leaking you should see seepage at the bell housing = slave cylinder.

      just did mine, that is what it turned out to be. clutch would drop to floor and not return to position and i couldnt shift into any gears. even if your brake fluid is a hair below the minimum, it can still draw air......good luck.

      What does the pedal feel/behave like?
      I do not understand why some coupes make the grade and others do not. Everyone knows, for instance, that the Corrado was as tasty as an East End prize fighter with the looks of a Benetti super-yacht. The four-cylinder was good, but the VR6 was about as close as you could get to Ferraridom without buying a Ferrari. And what happened? You all went to the pub instead. -Jeremy Clarkson-

      I just replaced both the slave and master to resolve the exact same symptoms. Probably best to go ahead and do both - if you're gonna be in there and can afford it.

      My symptoms actually included the clutch pedal sucking down to the floor - I mean, it would literally move from under your foot and suck straight down to the floor.

      For awhile I was driving it with a piece of cord tied to the clutch so I could pull the pedal back up - while waiting for parts to arrive.

      Amazing what happens when the daily kicks the bucket. 285,000 miles out of a 2001 Ford Focus ain't bad though

      Sorry to be the one to tell you this but unless one has been replaced they both should be done. Usually when one goes the other is right behind it. If you can't spare the loot, look for known working used ones until you can find the $ for brandy new ones.

      this is quite common when bleeding rados. Overfill the MC with fluid, the weight of it will help push the air 'down' & out. try it before you do anything else.

      Having similar problems this past week. Temporary relief was just bleeding the slave cylinder. Yesterday - finally had enough time to do a full bleed at each caliper and the slave cylinder and it seems to have cured the problem. Pumped 96 oz. of fluid thru the system. Make sure to start at the rear right, then rear left, front right, then front left when bleeding the brake calipers. I did the slave cylinder last.

      I highly recommend getting a brake bleeder tool from the local autoparts store. My local HarborFrieght carries one that's on sale for $25. Makes it whole lot easier than pumping pedals!
