Take it to someone how knows how too.
To remove the brake booster on a Chevy Celebrity: about the same for all years 1. Under the hood take off the 2 nuts that hold the master cylinder to the brake booster. Move the master cylinder out of the way. 2. Detach the vacuum line from the brake booster. 3. Inside the car Remove the under dash panel. 4. Remove the nut that holds the brake rod to the brake pedal, remove the brake rod from the brake pedal. 6. Remove the four nuts that hold the brake booster to the inside firewall. They can be a pain in the neck to get to. 7. Under the hood pull the brake booster out of the firewall. It can be a tight fit by the master cylinder. Reverse the process to install the replacement brake booster.

No. There are three different tops for the C4 Corvettes, 84 to early 86, late 86 to 88, and 89 to 96.

If you push on the brake pedal and the engine RPM goes up that would be an indicator. After running the engine for a while shut it off and wait a few minutes. Remove the vacuum line and connector at the booster. You should hear a burst of air rushing in. This would indicate that the booster is holding vacuum....which is what you want. You can also start the car and depress the pedal. Turn off the engine. If the pedal stays in the same position for 30 seconds this would indicate the booster is air tight. If it fails any of these tests it's a good bet you need a new one.
