ASA e sebelisa letoto la meaho e tsoetseng pele ea mochini ho bona ho tsoa ha mariki ka nako ea nnete le ho etsa liphetoho ha ho hlokahala.

Haholo-holo, ASA hangata e na le rack le pinion (control arm), clutch, thrust spring, worm gear le worm, matlo le lisebelisoa. The rack le pinion li sebelisoa ho laola boleng ba theoretical brake clearance, ha motsoako oa "thrust spring" le clutch li sebelisetsoang ho khetholla ho hlaka le ho hlaka ho feteletseng nakong ea braking. Sesebelisoa sa sebōkō le sebopeho sa seboko ha se fetisoe feela torque ea braking empa hape se lokisa phepelo ea brake nakong ea ho lokolloa ha brake. Ha tumello ea brake e le kholo haholo, ASA e ikamahanya le maemo ho e fokotsa; ha e le nyane haholo, e etsa litokiso tse tsamaellanang ho qoba ho tsofala ho feteletseng kapa ho ts'oara lesela la khohlano.
