I couldn't reply to you E-Mail as it kept saying Invalid so I posted it here. JT check Eddie Stakes vender list for the proper booster. Do you have the original one? There are places that will rebuild yours. The only difference between the drum brake booster and the disc one is the disc booster is a double diaphragm and the master cyl. mounting flange is different along with a larger reservoir for the disc side of the system. I have 2 74 Hornet Hatchbacks. One I bought new with manual drum brakes that I added the dealer power drum brake kit to a few years later. 4 years ago I converted it to disc's with disc's and rotors from a non power brake 79 Concord. I kept the original 74 drum power brake booster and master. I removed the residual check valve for the front disc's. It didn't even need a proportioning valve. The brakes work fine. The only difference between the factory disc brake car and my hybrid is the hybrid needs a little more pedal pressure to make it stop but not much. It has worked fine for 4 years now. The new 72 Matador I just bought has a 75 Matador disc setup on it with the drum brake booster/master set up and it to works fine. Hope this helps by giving you an alternative that works in case you can't get the proper booster. Both of my 74's are 258's.

My 14 year old son and I went in on a Hornet project this fall. We have made some headway on getting it running much better. We're still getting hung up on some of the brakes. Do you have or do you know of anyone who has power brake booster for disc brakes from a 72 or 73 Hornet ? I'd like to have an original to go by, even if I get one from NAPA. So far I've been sold a non-returnable drum booster by accident. It doesn't fit without mod's. I'd really like to find the correct one. Thanks Doc. Get back to me when you can. Our car is a 73 hatchback with a 258. J T -------------- next part -------------- An HTML attachment was scrubbed...
