If the booster is good, do I have to remove it and disconnect from the pedal? I thought the MC is bolted to the booster and you separate it there? Am I mistaken? Thanks.

You can remove the MC without removing the booster. Pretty simple.

Thanks, I thought so. Not sure what the other guy was saying about removing it from the brake petal.

Is the ZR-1 master cylinder any different than the base engine master cylinder?

There are variations depending on years. Whether interchangeable between standard C4 vs. ZR1s, I don?t know.

According to above, perhaps 92 to 95 had minor difference (fluid reservoir?) specific to ZR1s.

Mine is a 1990. Shows up on page 1 of that link.

Sorry, I was thinking of the clutch master. My bad.
