9inch Ford rear disk brakes

I have a 71 Mach 1 with a 9 in rear. My manifold vacuum is 12 inches. I bought a brake booster that makes a lot of noise. I was thinking about installing rear disk brakes. I was hoping this would eliminate the need for the vacuum pump. Any ideas? Thanks.

What kind of "NOISE"?

The sound of the pump running. It vibrates the whole front of my car.

Something's wrong. You sure it's the booster? Other than a friendly brake, you should never know it's there.

Thanks Critter for four help. I was realy trying to see if switching to rear disk brakes, I could eliminate the need for an artificial part that could fail at some point causing my brakes to fail. Last week going to a car show, my ground wire to the vacuum pump came loose and the pump failed to run. That reaily could have been trouble. I was lucky I got the car stopped. Thats why the rear disk question. Thanks.

I would think with 12" of manifold vacuum you could run a parts store brake booster, no electrical connections at all, and be done with it.

Thanks Paul for your info. I think I will try a new brake booster first before going to rear disks.

going rear disc wont helpyour braking problem it will make it worse if anything. drums are self actuating brakes and dont require a booster. where as disc brakes need all the boost they can get. it sounds like you have a electric vacuum pump in your car. 12 inches of vac is not great for a booster. are you runing a extra storage tank as well as your booster?.
