2.6.6 Brake control system
The main
wheel
brakes (Fig
.
8) are actuated hydraulically using the brake lever 2
(installed
next
to the throttle
lever
3) controlling
the
pressure supplied from the master cylinder 1 to
the slave cylinders 5 in the wheels.
The main
LG
wheels have disk brakes. The cylinders are connected to each other with
copper tubing 6 with outside diameter of 3 mm. The master cylinder 1 is connected with a
hose 8 to
the
extension tank 7,
installed
on the firewall
in
the engine compartment.
When the
brake
lever is pulled the brake pads squeeze the brake disc creating the braking
moment proportional to the applied force.
A-22L2 is equipped also with a parking brake, which is actuated
with
a
lever
4 on
the
central console. To use the parking brake, set the
lever
to
'Parking
brake ON',
then
pull
and release the brake lever. The brake pads will remain pressed to the brake disc. To
release the parking brake set its control
lever
to
its
initial position ('Parking brake OFF').
