Isimiso sokusebenza se-brake ngokuyinhloko sisuka ku-friction, ukusetshenziswa kwama-brake pads kanye ne-brake disc (isigubhu) namathayi kanye nokungqubuzana komhlabathi, amandla e-kinetic wemoto azoguqulwa abe amandla okushisa ngemva kokungqubuzana, imoto izoma. Isistimu yokubhuleka enhle futhi esebenza kahle kufanele inikeze amandla okubhuleka azinzile, anele futhi alawulekayo, futhi ibe namandla amahle okudlulisa amanzi kanye namandla okukhipha ukushisa ukuze kuqinisekiswe ukuthi amandla asetshenziswa umshayeli osuka kubhuleki angadluliselwa ngokugcwele nangempumelelo empompini enkulu kanye amaphampu amancane, futhi ugweme ukwehluleka kwe-hydraulic kanye nokubola kwamabhuleki okubangelwa ukushisa okuphezulu. Kunamabhuleki edisc kanye namabhuleki ezigubhu, kodwa ngaphezu kwenzuzo yezindleko, amabhuleki ezigubhu awasebenzi kahle kakhulu kunama-disc brakes.
ukungqubuzana
"I-Friction" ibhekisela ekuphikisweni kokunyakaza phakathi kwezindawo zokuthintana zezinto ezimbili ezinyakazayo. Usayizi wamandla okushayisana (F) ulingana nomkhiqizo we-coefficient (μ) kanye nengcindezi eqondile eqondile (N) endaweni yamandla okushayisana, evezwa ifomula ephathekayo: F=μN. Ohlelweni lwamabhuleki: (μ) ibhekisela ku-coefficient yokushayisana phakathi kwe-brake pad ne-brake disc, futhi N i-Pedal Force esetshenziswa i-brake caliper piston ku-brake pad. Uma i-coefficient ye-friction enkulu ekhiqizwa ukungqubuzana okukhulu, kodwa i-coefficient ye-friction phakathi kwe-brake pad ne-disc izoshintsha ngenxa yokushisa okuphezulu okukhiqizwa ukungqubuzana, okusho ukuthi, i-coefficient ye-friction (μ) iguqulwa izinga lokushisa, uhlobo ngalunye lwe-brake pad ngenxa yezinto ezihlukene kanye nejika elihlukile le-coefficient, ngakho-ke ama-brake pads azoba nezinga lokushisa elihlukile elifanele lokusebenza, kanye nebanga lokushisa elisebenzayo, leli wonke umuntu kumele azi uma uthenga amabhuleki pad.
Ukudluliswa kwe-braking force
Amandla asetshenziswa i-brake caliper piston ku-brake pad abizwa ngePedal Force. Ngemuva kokuthi amandla omshayeli enyathela i-pedal ye-brake ekhuliswe i-lever ye-pedal mechanism, amandla akhuliswa ukukhushulwa kwamandla e-vacuum kusetshenziswa umgomo womehluko we-vacuum pressure ukusunduza iphampu eyinhloko yebhuleki. Umfutho we-liquid okhishwe yiphampu ye-brake master isebenzisa umphumela wokudlulisa amandla angacindezeleki we-liquid, odluliselwa kwipompo ngayinye encane ngeshubhu lamabhuleki, futhi "umgomo we-PASCAL" usetshenziselwa ukukhulisa ingcindezi nokuphusha ipiston ye-sub- futha ukuze usebenzise amandla kuphedi yebhuleki. Umthetho kaPascal ubhekisela eqinisweni lokuthi ukucindezela kwamanzi kuyafana yonke indawo esitsheni esivaliwe.
Ukucindezela kutholakala ngokuhlukanisa amandla asetshenzisiwe ngendawo ecindezelekile. Uma ingcindezi ilingana, singakwazi ukufeza umphumela wokukhulisa amandla ngokushintsha ingxenye yendawo esetshenzisiwe necindezelwe (P1=F1/A1=F2/A2=P2). Kuzinhlelo zokubhuleka, isilinganiso sephampu isiyonke ukuya kumfutho wephampu engaphansi isilinganiso sendawo yepiston yepompo eliphelele endaweni yepiston yephampu engaphansi.
