8.7.6 Brake control system
The main wheel brakes ( Fig. 9 ) 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 4 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-22LS 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').
