Ive looked all over and cant find much on this that I dont know already. I pulled this MC from the 78 donor and it is an aluminum Bendix MC. Kind of special it turns out since I dont think bendix makes any more aluminum MC anymore and any other brand MC that I found that was aluminum was over $100 and that is not including if it will go with the 67 Gal booster I'll be using. So, provided I dont find anything, is there anything I need to know about rebuilding these beyond what is elementary. I read that it is best to buy MC new because remanufactured MC are prone to more chance of failure, unless they are SLEEVED whatever that entails. What and how is sleeving. Oh, it is a 1" bore which I guess is supposed to be good.

71pinto, what are viton rings anyway?

I'd just get a new iron one from a similar application. I've rebuilt iron ones and the biggest problem especially on a master that sat for a long time is water separation (from a freeze thaw cycle) in the bores that pit the bore wall. If you can't hone it smooth then the new seals will eventually fail from abrasion on the rough surface. Stu

Thats just the thing, isnt aluminum supposed to be resistant to that hence the higher cost. Also, if I can save this that would be great due to the big difference in weight. I do alot of extra legwork to save on weight everywhere I can.

Viton is the type of rubber. Its very resistant to oils ,and solvents.( not imperious
When it comes to The master cylinders, wheel cylinders and calipers i dont even think of rebuilding them. Its a lot of time and difficulty and no guarentee of a good seal.
Id look around for a qualitly rebuild and just bite the bullet. Its your brakes after all.

Well can you find a rebuild kit for it? If you can clean it up and get a hone go a ahead.

Just a thought, I have seen a lot of swaps use modern Dodge full size van aluminum masters for various swaps. Think the have a similar foot print to Fords. Stu

Yeah, I read that somewhere to but I cant remember if they were using a power booster or not and what year/model Dodge van it was. Time to look through the archives. Unless it is one with a plastic reservior. That just wouldnt look right in a 65 Gal to me. Yeah, I'm picky............I know.

Sleeving one is just thev same as sleeving a bore in a block of an engine, but a brass sleeve is pressed in, its done a lot here in New Zealand and meets our VERY hard laws.

I did some checking on this MC with Bendix and I'm being told it's original application is a 1981 Pontiac Firebird!! What the ****? How this ended up in a 78 cougar I can't figure out. Anyway, I checked with a company called White Post Restorations and they quoted me at $225 for a complete rebuild w/sleeving. Im not cheap, but it is hard to pay that much when I think I can do it myself for alot less and say I did it. I don't know maybe I should just settle for a new cast iron one and be done with it. I sure would like to save the weight though. Hmmmmmmmm.

You can get new aluminum one. Check with a good auto parts store. Bendix, Wagner, Raybestos, Napa. Just give them the application and they should hook you up. $225 is way to much.
