These can break, mine did, so here's the part number. Do NOT ever remove yours! You need it in place.

GM #12558195.

I remember a ton of guys were removing their clutch pedal spring as they thought that would help with the dreaded sticking clutch pedal. I never thought that was a viable solution so I never did it with my c5.

With my c6 I follow GM's suggested 24 month clutch fluid replacement and in my stock form I find that I have not had a sticking clutch pedal.

It was terrible in my c5 z06 and I swore that if it happened in my c6 I would forever never own another GM stick shift vehicle...

I need to change mine pretty soon. What's the best fluid to use? I've heard that some of the off the shelf stuff may cause more problems....

HI there,

Any DOT 4 brake fluid is acceptable for c5 or c6 clutch hydraulic system. The GM recommendation is 88958860 Super DOT 4 fluid.

Now, I prefer ATE Super Blue DOT 4 as this is the fluid that Corvette engineering uses when they do prototype testing and it works extremely well.

Allthebest, c4c5
