BA8 Booster

The Model BA8 is a ram type double-acting booster lower in first cost than the Model B4 but is neither self-bleeding nor self-filling. 

It is therefore recommended for use only where complete manual bleeding and filling can be easily effected and maintained. 

It utilized the miller self-adjusting, leakproof seal that permits no oil seepage. 

The BA8 can also be operated by hydraulic input.
