I am at my wits end... Recently installed a new clutch master cylinder,after install I noticed clutch pedal had an inch of free play before it engaged at the pedal.. Previous to this there was no free play. I know its air in the system so I preceded to gravity bleed from the slave cylinder below. Car is driveable but I can tell it isn't right. What is the next step after the traditional clutch pedal pump, crack the bleed screw operation isnt successful? I understand the c5's are notorious for problems in this department....thoughts?

I was told by a well known corvette "authority" that gravity bleeding does not work on c5's and that I am better off getting a new slave cylinder and clutch master cylinder installed for 1500.00{parts and labor}

I don't know what is wrong with your car but I think there is something wrong with your Corvette "authority".

Take the MC out and bench bleed it again.

When you reinstall be sure to screw the MC completely into the firewall. The last few degrees are a biotch. I used a small C clamp to get some leverage.

Air bubbles rise. Give it a day or two.

First off, why did you replace the master cylinder?

Yes, you should bleed the system through the bleeder. It's a pain in the *** to get to. I use a stubby wrench and put the closed end over it. Just let the fluid come out of the bleeder and all over the place, you have no choice really. Remember to have an assistant pump the pedal and instruct them to make sure the pedal comes back all the way up. They may have to pull the pedal up with their toes or hand. The fluid will deplete quickly, after 2 bleeds, fill the reservoir.
