Clutch pedal goes to floor. I change the clutch, pressure plate and throw out bearing. Still no clutch pedal. Changed out the cylinder that presses against throw out lever arm and bled it. Still no clutch pedal. Changed out the clutch master cylinder and filled back with dot 3 Fluid. Still no clutch pedal.

SOURCE: I replaced the slave cylinder on my 91 G.M.C.

Yes, get a pro-bleeder. They are around $ 75-$90 but well worth it.

SOURCE: 1997 GMC Sierra 5.7 changed master cylinder

check under your master cylinder,is there another clyinder below with one line in and one line out,if you do I found this is for the Abs to the rear,I had to replace this it was full of air,and did exactly what yours is now

SOURCE: Having trouble bleeding the clutch on a 89 K1500.

try pumping the fork at the clutch slave with a large screw driver. make the fluid go backwards. Do not open the bleeder. I did this with a camero and it worked. hope this helps.

Provided the mechanical portion of our clutch is good then you still have some air somewhere in the hydraulic system and it's often very hard to get out. One trick I use is to use my hand vacuum pump with a little cover I made to cover the fill hole on top of the master cylinder. I pump up about 15" of vacuum on the system and often that will pull out the few air bubbles submerged in the fluid that prevent the system from working. Once you get most of the air out usually the rest will work out if you press and release the clutch pedal several times. Sometimes it works very quickly, sometimes I've fought them for an hour or more to get back to a normal pedal. Of course if you have an actual mechancial problem inside the bellhousing with the pressure plate or disc then nothing you do on the outside will work until that is repaired.

SOURCE: the clutch pedal dropped to the floor....was no

The clutch pedal assembly made of ABS plastic has a small lip holding clutch master cylinder. If the lip breaks, your clutch master cylinder assembly will shoot away from firewall & your clutch pedal will drop to the floor. Usually you will hear a loud bang when it breaks while depressing the clutch pedal. You can purchase the clutch master cylinder assembly with aftermarket & it looks just like the GM brand only over $100 cheaper. The Clutch pedakl assembly cost aprox $85.00 at a GM dealer. Bought mine online for $65.00 Org. GM part. Be aware removing & replacing the clutch pedal assembly is a real pain as theirs limited sight & room to work under the dash
