In a normal braking operation, pedal operation
causes the relative travel distance to remain so
small that the distance required for engagement is
not exceeded.
The lock sleeve is held in its rest position by the
force applied by the spring, the ball cage remains
free to move axially and the balls remain free to
move radially.

If the activation threshold level is.exceeded
because of an emergency braking situation, i.e.
the relative travel distance of the valve piston is so
great that the balls are moved in over the slope of
the ball sleeve, then the lock sleeve can move
completely to its end position.
I
--
The balls are now locked, and the ball sleeve can
no longer be moved in the closing direction of the
disc valve.
The EBA is now active, the brake pressure is
increased up to the wheel locking limit, and the
brake pedal can be moved to its maximum
pressure point without effort.
The brake pressure remains at the ABS control
limit until the EBA is completely released again.

DESCRIPTION AND OPERATION
Release of the brake assistant
Item Description

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.
