Joey:
Others will likely give you advice on where to get the booster rebuilt. I
would like to offer a suggestion that I have found to work quite well.
Corrosion inside the vacuum drum tends to be a particularly troublesome
problem area. What happens is that the brake piston seals (rubber) go bad
and brake fluid is sucked into the vacuum drum by engine vacuum. The brake
fluid accumulates and over time saturates the leather vacuum seal ring.
Brake fluid absorbs water so over time, especially if you do not drive the
car (and use the brakes) regularly, the inside of the vacuum drum corrodes.
The result is sticky brakes - they can get stuck on or simply perform
poorly.
My solution to this problem has been to:
A. Move to silicon brake fluid
B. Rebuild the brake servo unit
C. *** Either chrome or nickel plate the vacuum drum inside and out
***
I then powder coat in black the outside of the drum to make it look
original.
The end result has been SMOOTH brakes that last even when I don't drive the
car all that much.
I paid $20 to get a 5 inch drum nickel plated and $100 to get a 7 inch drum
chrome plated (I prepped the inside surface using sandpaper to remove
corrosion and get it "fairly" smooth - doesn't need to look like glass). I
have had good experience with both approaches.
