The Stovebolt Site Forums The Parking Lot Big Bolts BRAKES ON A 1953 6400

Is it the older style of Bendix Hydrovac, looks like a coffee can with 4 J-bolts, or a Midland type Hydrovac, looks almost like what a newer truck might have.

This is what a later model Bendix or an early model Midland booster looks like.

This is what the older Bendix models look like.

I believe the Midland types are supposed to be a sealed assembly with no way to add fluid but im not positive.
