Armand,
Just asked him about prices to have the brake system rebuilt; hope to have it done in the 6 to 8 months. Working to get the body repaired and painted right now. My goal is to have the Ole Girl restored by December 2019.

Bumping this old post to see if others have used Brake Materials and Parts in Fort Wayne, for restoring original brake booster? I know Boosters by Dewey is used by many but this place is closer to me and have read good things as well.
Thanks!

There is a slight whistle in mine on cold startup. No performance issues.
Inquired about getting it rebuilt and there is only one shop within an hour of me that would do it for $375 CA. He stated that there is a bushing in these that is unique, currently unobtanium and he only has a half dozen left - so if I want it done, it should be sooner rather then later. Replaced the check valve and grommet so that's not the source of the whistle. $375 for an annoying whistle is a bit much, but $375 if the booster fails is very reasonable, how long to wait dilemma! Likely going to do it this February or March. Parts are definitely getting scarcer!

It's common for them to get hairline cracks on the back of the booster due to vibrations. You might check that first before you send it off. You'll probably have to remove it from the car to inspect unless the cracks are huge.

too bad you couldn't get your booster restored. I found a company that took it apart and sent the booster covers back (they are two pieces) and I had them powder coated. I worried that when he reassembled the two half's it would get scratched up. Nope, looked perfect. You could tell some minor scratching where the two pieces come together, but you really need to look. Car has been running with it for 12 years and no problems and the powder coat black is as good as day one. Kind of a late story, just thought someone else would like to know. O, and they also restored the reservoir. Same process.

If there are cracks, I'll be taking the booster apart myself and TIG welding those and maybe install some reinforcement on the inside if possible.
Then we will see about any restoration. Curious about this unobtanium bushing also. If there is a bushing that is the problem, can likely make one of those myself. Have not seen a rebuild kit that includes the diaphragms for sale. I'm assuming the rebuilders have a cross reference for Bendix parts. Found the number for the rebuild kit MP500828, 8-3/4" dual diaphragm Bendix booster. But not found anyone with stock.
