The other day I went to start my C5 corvette after not driving it for a few weeks only to find 2 pedals where normally 3 pedals should be - clutch decided it had enough and fell to the floor.
Apparently it’s a thing - clutch fluid gets really dirty, boils and has air bubbles. I did the Ranger’s method - suck out the fluid from reservoir as much as possible. Add new. Pump clutch few times. repeat until liquid is clear.
When I was backing into a spot, clutch was pushed in and I was on the friction zone trying to give it just enough to not go too fast and bang up underside. Anyway - clutch was sticking again.
I am planning on changing out the clutch master cylinder. Got one from autozone. I am certain it’s crap quality but better quality than what I have in C5 now. It came without the hose to clutch slave cylinder and I am thinking of re-using it.
Would you re-use it or would you get a new one? Problem with getting a new one is where the connection is and how pain in the ass it is to detach and attach plus I don’t believe there are any problems with the hose. only that maybe inside the hose has some gunk.
Lots of problems with C5 as of late - hazard lights button got stuck in the dashboard (typical). Clutch needs a little viagra to stay up. Clutch position sensor might be going faulty - won’t recognize pedal being pressed and blocks the car from starting. Brake fluid is dirty too - need to flush it this weekend.
Somehow japanese cars never had these issues - Drove my Acura Integra for years without any of these problems. Weird and disappointing.
Yes, that’s a C6 shifter. I have it in my C5

I would reuse it, unless it will be exponentially more challenging to replace in the future or if it’s readily available for cheap. And I haven’t had clutch issues in any car I have owned except the two Saturn Ions. I think some GM hate is deserved

From what I’ve noticed on pages, is that they need to be driven a lot to stay in running order. People who I know that daily them, don’t have really any issues. Let em sit for a week, and then suddenly they don’t work.

Na, they just burn oil, eat synchros, pop HGs, and rust like crazy........

I’m gonna re-use it. I am hoping the issue lies in master cylinder. I’ve cycled the fluid in the system enough for it to be clean.

The title from your post has put a song from Singin’ In The Rain in my head as an earworm.
I totally don’t have brain damage.

And just like that I shifted from AC/DC to Debbie Reynolds.

Clicks on link and thinks to myself that it looks like a C6 shifter.
Starts reading about C5... wait what?
Gets to end. Oh, ok.

To add to the layers of kayfabe in the scene, that was one of the songs Debbie Reynolds didn’t sing, and she was dubbed by Betty Noyes for that scene. So, that scene has one person singing with a put-on atrocious voice (herself a good singer), being dubbed by someone else who is herself being dubbed, singing a song that’s (in-movie) written for a musical in the movie, but is in real life written for another musical and originally sung by Jeannette McDonald - another singer altogether

It has in it what is probably the most challenging physical comedy montage ever filmed.
No tricks or wirework, all filmed in nearly one take.

When my Mazdaspeed 6 had its clutch pedal fall to the floor, the slave cylinder was the culprit. Master was fine. Don’t assume it’s the master.

All posts point to master cylinder being the culprit... more accurately clutch dust finds its way into the fluid and causes hydraulic issues. One can bleed the system, but you need to get to bell housing area which means i have to drop exhaust pipes and few other covers under car.
If it’s the slave, then it is going into the shop for a new clutch and other stuff.
I don’t know about other versions of corvette, but at least in this one, there is a drive shaft that is inside of a torque tube. That all is attached to transmission which is in the rear of the car. To get to slave, you need to remove the torque tube which means you have to drop transmission or at the very least wiggle it back a bunch which will get iffy without a proper jack under it.
Long story short, it’s way too complicated to be doing alone in a driveway. It can be done. I’ve seen it done in a driveway, but not by one person. My buddies are not able to assist mostly because they can’t tell difference between hammer and screw driver.

Ah, yeah I forgot about the rear transaxle. That’s present in the C5 thru 7 . My MS6 was a typical fwd-based awd layout with a transverse engine and transaxle, and the slave cylinder is a minor job.

replace the master and slave at the same time

Yeah I just recently did a clutch on a C5, and it was enough of a pain in the ass in a shop with a lift. I definitely wouldn’t want to do it in my driveway.

I’ve done it on my 97 three times now over the years. It’s not complicated at all. 10 bolts for the exhaust, then 26 (if i remember right) for the tunnel brace. There’s an access panel on the bottom of the transmission that’s another 6 bolts and you can see your clutch fine. No fluid in there? Unlikely the slave.
When I swapped my clutch to a McCleod earlier this year, I put the car on 4 jack stands, popped the connectors off the rear brakes, pulled the A arm bolts, loosened the cradle bolts, disconnected the transmission and rear brake harness, loosened the torque tube (there is no drive shaft in the C5. It’s a prop shaft, which is very much not the same thing) bolts from the transmission, put the rear cradle on a jack and the front of the torque tube on a jack by myself.
At THAT point, a buddy came by to help make sure it was balanced as we pulled her out of the engine.
It’s literally doable (full clutch swap) in about 10 hours. I took the time to rebuild my torque tube because my giubos were clearly trash.

I am not losing fluid. I don’t think slave is leaking, however, some claim dust from clutch gets into the fluid and causes issues. That doesn’t make much sense to me as it’s a closed system and if dust could get into fluid, fluid would be able to leak out.
However, i did read a different article where their hypothesis is that the heat build up causes fluid to expand and forces slave cylinder position to more farther out. At some point the pressure plate clutch forks don’t have enough spring tension to force the fluid back into the master which would explain why clutch pedal drops.
So while dirt in hydraulics don’t help anything, i think the underlying problem is heat and perhaps weaker than normal clutch fork spring tension due to wearing.
All that said - I don’t think i need to replace the master cylinder after all. Maybe bleed the system. Maybe add fluid that can withstand higher heat. Down the line maybe replace clutch components to high performance.
There was also talk about drilling something but I am not too clear on it. Drilling out some openings that GM thought would make things better if they kept fluid flow restricted.
