Mgbe breeki master cylinder anaghị arụ ọrụ, isi piston na iko dị n'ihu na ụlọ azụ dị n'etiti oghere uzo 10 na oghere nkwụghachi ụgwọ 11. Ihe na-agbanwe ike nke nkwụghachi mmiri nke piston nke dị n'ihu cylinder dị ukwuu karịa nke nlọghachi azụ nke piston nke azụ cylinder iji hụ na piston abụọ ahụ nọ n'ọnọdụ ziri ezi mgbe ha anaghị arụ ọrụ.
Mgbe ị na-agba breeki, onye ọkwọ ụgbọ ala na-arịgo na pedal breeki, a na-ebufe ike pedal na mkpanaka mkpọ 15 site na usoro nnyefe, ma na-akwanye piston azụ cylinder 12 ka ọ gaa n'ihu.

N'okpuru omume nke nrụgide hydraulic n'ime ụlọ azụ na ike mmiri nke azụ cylinder azụ, piston 7 nke cylinder dị n'ihu na-aga n'ihu, na nrụgide dị n'ihu ụlọ na-abawanye. Mgbe pedal na-aga n'ihu na-agbada, nrụgide hydraulic dị n'ihu na ime ụlọ na-aga n'ihu na-abawanye, na-eme brek n'ihu na azụ.
Mgbe a tọhapụrụ breeki ahụ, onye ọkwọ ụgbọ ala ahụ na-ahapụ pedal breeki, n'okpuru ọrụ nke isi iyi piston n'ihu na azụ, piston na ọkpọ ọkpọ na breeki master cylinder laghachi na ọnọdụ mbụ, na mmanụ dị na pipeline na-emepe valvụ nloghachi mmanụ 22 ma na-agbaghachi azụ Onye nwe cylinder na-agbaji, nke mere na mmetụta nke braking na-apụ n'anya.
