After Ken mentioned I should check the booster for a vacuum leak I decided to replace it. After all, it was 32 years old.

Remove the master cylinder from the booster is pretty straight forward.

Get your frustrations out of the way first, jump up and down, scream, and throw something whatever works.

Don’t bother with the plate in the window wiper well, there is no access.

Remove your driver seat, will make life much easier. I couldn’t, the vette had its engine removed and the left side was only 2 feet off the garage wall.

Crawl under the dash with a 3/8” socket, ¼ drive and remove the neutral safety switch. It’s a pain to remove but if you don’t you won’t be able to see or get to the left top booster nut.

Get a 9/16 deep socket and attach a swivel joint to it. Then add a 6” extension and attach your ratchet. Go after the left top on first as it is the hardest. You will need to slide the socket over the top of the clutch pushrod. You may also need to unfold the harness retainer that is high up on the kick panel side near the fuse box and move the harness down.

Now go after the other three nuts which are not too bad.

Remove the clip on the pin which attaches the brake push rod to the brake pedal.

Now you can remove the booster.

Boy am I glad that’s done!
