Brakes
The foot brake is of the hydraulic type and
operates on all four wheels, because the two
rear wheels are mounted on a rigid axle. The
maintenance of brake includes checking the
brake fluid level. The brake master cylinder
with the fluid reservoir is situated below the
seat bench and is accessible through simply
unscrewing the bakelite filler plug. When
removing it take care to avoid getting dirt into
the brake fluid. Use only original ATE blue
fluid from the original can (figure 74). Too
much free travel of the brake pedal is an
indication that air has come into the hydraulic
system; then the fluid line must be bled. This
can only be done in a service station as it
requires special devices and technical
knowledge, as well. The brake adjustment,
however, may be carried out by the driver
himself. The brake support plate carries,
beneath the wheel bearing, an adjustment
screw, the clockwise rotation of which moves
the brake shoes against the drum. First
slacken lock nut on adjusting screw, then set
the screw as described ahead and re-secure
it in its final position by tightening the lock nut
(figure 76). To obtain the proper adjustment
jack up the car and rotate the wheel to be
adjusted until a light drag is noted and then
back off the adjusting screw until the wheel
just turns freely. Figure 75 shows the brake
with the brake drum removed.
The adjustment of hand brake may be
performed by means of two 12mm spanners.
Slacken the lock nut and then screw out the
adjusting screw until, with the hand brake
lever set into its lowest position, the brake
just begins to rub. Now return the adjusting
screw by 1 to 2 rotations and secure again
with the lock nut. The hand brake must not be
adjusted unless the foot brake has been set
correctly (figure 77).
