Sticky clutch pedal
My clutch pedal started to get stuck in the down position a few months ago when I hold it down at a stoplight. I can easily pull the clutch pedal back up but this problem is starting to annoy me. Does anyone know how to fix this?

I would try a system flush and see if that helps...
If not, it may be time for a clutch/slave cylinder replacement.

its your master cylinder seals going bad. TRUST me. I went through this battle, fluid flushes, slave ctyinders to no avail.
If your having problems with the pedal staying low from stop lights and stuff thats the masterc cyilinder its only like 60 bucks you can have a shop install it

I put the master cyilinder on and didnt even have to bleed the rest of the system due to the self sealing quick disconnect.
The parts available at the parts store being exactly the same part has LONG been proven. Im well versed in this.

go to your local parts store. Its the same OE manufacturer makes them for them. its the same part. they are 60 ish. has same logos and part numbers on them. swapping the master cylinder on the vette is the easiest one ive ever done. Jack up the LF wheel, remove the lower wheel liner(bottom section) and BAM your hands on with it. Pop the clip at the pedal and the master cyilinder just Twists off. Swap the line then bench bleed it by using putting it in a vice having someone pump the pedal and then using a nail to open the end.
I put the master cyilinder on and didnt even have to bleed the rest of the system due to the self sealing quick disconnect.

The ones you're recommending don't come with the resevoir and aren't bleed.
That's why they are cheaper. Personally, I would want to replace the whole unit as it's easier.
If you have to bleed the unit that means dropping the exhaust and tunnel plate.

you simply bench bleed the master and install. FWIW I had it setup as you described with the resivour installed and such and it was hard to install it that way because you have to twist the mastercyilinder to install it, which means it twists the line and the resivour, I found better success takeing them off and reinstalling them and then using a mighty vac to take care of any air from the removal of the resivour.

no you dont, thats the point of the quick disconnect. the line from the end to the slave is sealed presure tight.

That is not required. That is what the nail is to press open the fitting on the end of the line for. This opens the line allowing you to bleed over and over untill its firm. Took about 3 minutes to do entirely

Next time you change your engine oil I would change the clutch fluid with a high temp fluid like motul ; it's expensive.
If this doesn't fix the problem change the master cylinder and slave as previously suggested.
I would make it a practice to change the clutch fluid with each engine oil change.
