How can you tell if your brake booster is good?

Shame on you, Guy. The procedure for testing the Master Vac is in the FSM. Just read the BR section. In the 72 FSM, it starts on page 21. While I know you are referring to your 71, it should be the exact same procedures.

By the way, give me a call on my cell phone when you get to the convention.

Will do......We should get there Monday at about 2:00. I found the test in the FSM......If I can get all the plumbing to run the test, it should answer my question. Guy

D, I just ran this check. You will need a vacuum gage. I thought my brakes were fine for 3 years until I did the test in the factory service manual. I posted up my entire rebuild story.
