Reply to "Brake booster won't hold vacuum, should I rebuild/replace it?"

In two of the three misbehaving boosters I had the issue turned out to be the seal at the MC pushrod. Both had aftermarket MCs with adapters that coincidently used a special seal common to both. Karp had them on hand.

Booster number three will pull good vacuum, but doesn't provide any assist. It will just have to wait for now.
