Clutch pedal stuck to floor

[benny]

1996 D1 5 speed. Every now and then while vehicle is stopped, I push in on my clutch pedal and it goes and stays to the floor. Sometimes I can lift it with my foot but usually I have to start pumping the crap out of it to get it back to normal. Then it acts OK for a while. Never any trouble while driving and changing gears, only when truck is stopped. All the searches seem to point to Master or slave cylinder going bad. Don't see any leaks at either. Going to try to bleed it first just to make sure theres no air in it but will probably end up replacing both. Are the ones from NAPA or Advance any good or where is the best place to get them from?

Depends if it is mechanical stiction in the pedal pivot or something in the hydraulics.

To hold the pedal down against the pressure plate spring would need a fair bit of effort, unless your pressure plate is starting to fail.

I had the same issue. New master cylinder took care of it.

Did you replace the slave at the same time? I've read that one will usually go out soon after the first is replaced. Where did you get your master from?

Slave is ok so far. I can't remember where I got my MC from.
