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').
