Ụkpụrụ ọrụ ziri ezi nke mgbapụta brekị bụ dị ka ndị a:
Mgbapụ brek bụ akụkụ dị mkpa nke usoro brek chassis dị mkpa na sistemụ brek, ọrụ ya bụ ịkwanye pad brek, drum brek esemokwu nke pad brek. Jiri nwayọ nwayọ ma mee ka ọ kwụsị. Mgbe a pịrị brek ahụ, mgbapụta ukwu na-emepụta nrụgide iji pịa mmanụ hydraulic na sub-pump, piston dị n'ime sub-pump ahụ na-amalite ịkwaga n'okpuru nrụgide mmiri iji kwaga pad brek ahụ.
Ihe mejupụtara brek hydraulic bụ ọkpọkọ brek master na tankị nchekwa mmanụ brek. Ha na-ejikọ na pedal brek n'otu nsọtụ na ọkpọkọ brek n'akụkụ nke ọzọ. A na-echekwa mmanụ brek n'ime ọkpọkọ brek, e nwekwara oghere mmanụ na ntinye mmanụ.
1. Mgbe onye ọkwọ ụgbọala zọọrọ ụkwụ na pedal brek, piston nke ọkpọ mmiri ukwu na-aga n'ihu iji mechie oghere gafere. Mgbe ahụ, nrụgide mmanụ na-agbakọta n'ihu piston ahụ. Mgbe ahụ, a na-ebufe nrụgide mmanụ ahụ na ọkpọ mmiri brek site na ọkpọ mmiri ahụ;
2. Mgbe a tọhapụrụ pedal brek, a na-eme ka piston nke ọkpọ mmiri ukwu ahụ laghachi azụ n'okpuru nrụgide mmanụ na spring nlọghachi. Mgbe nrụgide nke sistemụ brek ahụ daa, mmanụ karịrị akarị na-alaghachi na ite mmanụ ahụ;
3, brek ụkwụ abụọ, ite mmanụ site na oghere nkwụghachi gaa n'ihu piston ahụ, nke mere na mmanụ dị n'ihu piston ahụ na-abawanye, wee na brek ahụ, ike brek na-abawanye.
