To release EBA, the brake pedal must be fully
released, i.e. it must be returned to its rest position.
When this occurs, the control housing together with
the valve piston move back into the rest position.
The key is pressed against the stop on the vacuum
cylinder and by this the lock sleeve is slid back into
its rest position.
The balls can again be moved outward by the ball
sleeve, and the ball cage is again free to move
axially and the balls free to move radially.
Service
It is not possible to repair the EBA. A new brake
servo unit must be installed.
