In July, clutch pedal stuck to the floor when backing up. Had to pull pedal up by hand for clutch to start working. Clutch pedal felt fine, didn't notice any difference in play. 3 wks. later, had the same problem, pedal stuck to floor, had to pull up by hand to get it to work, change gears. Again, pedal play felt okay. Decided to be proactive to stop any more problems so changed out clutch master cylinder & slave cylinder. Problems began immediately, clutch pedal wouldn't completely return when depressed and released and clutch pedal doesn't engage clutch until almost to the floor. When clutch pedal is released, clutch engages almost immediately, doesn't travel over an inch before clutch engage. Occasionally clutch pedal will stick to the floor and again has to be pulled up by hand before clutch will operate and trans can be shifted. Took to mechanic, said possibly clutch disc was bad. Pulled transmission and clutch and he said everything looked new (only 48,000 easy mi on truck), no problems detected. Still same problem, clutch pedal not releasing completely, gets about half way up and stops, have to raise it up with foot. Mechanic said thought air in slave cylinder. Bled slave cylinder multiple times, still same problem. Thought could possibly have gotten bad slave cylinder so bought another one. Completely immersed slave cylinder in bucket of brake fluid and bled out air 'til no bubbles appeared. Installed new slave cylinder, bled lines, still same problems. What's so confusing is that the problem with the clutch pedal not fully releasing didn't start until new master/slave cylinders were installed. I've spent in the neighborhood of $400 so far and still have same problem. I do have some mechanical abilities, worked on cars/trucks before, even changed a slave cylinder on an early model Toyota truck I had, with no problems. This one has got me stumped.
Any suggestions as to what might be the problem would be appreciated. I'm about 99.9% sure that there isn't air in the system as I've run about 1/2 gal of brake fluid thru the system while bleeding it.
