Mfundo yogwirira ntchito ya mabuleki makamaka imachokera ku kukangana, kugwiritsa ntchito ma brake pads ndi brake disc (ng'oma) ndi matayala komanso kukangana kwa pansi, mphamvu ya kinetic ya galimotoyo idzasinthidwa kukhala mphamvu ya kutentha pambuyo pa kukangana, galimotoyo idzayima. Dongosolo labwino komanso lothandiza la mabuleki liyenera kupereka mphamvu yokhazikika, yokwanira komanso yowongolera ya mabuleki, komanso kukhala ndi mphamvu yabwino yotumizira ma hydraulic ndi kutentha kuti zitsimikizire kuti mphamvu yomwe dalaivala amagwiritsa ntchito kuchokera pa brake pedal ikhoza kutumizidwa mokwanira komanso moyenera ku pampu yayikulu ndi ma sub-pumps, ndikupewa kulephera kwa hydraulic ndi kuwonongeka kwa mabuleki chifukwa cha kutentha kwambiri. Pali ma disc brakes ndi ma drum brakes, koma kuwonjezera pa phindu la mtengo, ma drum brakes ndi ofooka kwambiri kuposa ma disc brakes.
kukangana
"Kukangana" kumatanthauza kukana kwa kayendedwe pakati pa malo olumikizirana a zinthu ziwiri zomwe zikuyenda mozungulira. Kukula kwa mphamvu ya kukangana (F) kumagwirizana ndi zomwe zimachitika pa coefficient ya kukangana (μ) ndi vertical positive pressure (N) pamwamba pa mphamvu ya kukangana, zomwe zimafotokozedwa ndi fomula yeniyeni: F=μN. Pa dongosolo la mabuleki: (μ) amatanthauza coefficient ya kukangana pakati pa brake pad ndi brake disc, ndipo N ndi Pedal Force yomwe imagwiritsidwa ntchito ndi brake caliper piston pa brake pad. Coefficient ya kukangana ikakula, kukangana kumakula, koma coefficient ya kukangana pakati pa brake pad ndi diski idzasintha chifukwa cha kutentha kwakukulu komwe kumapangidwa ndi kukangana, kutanthauza kuti, coefficient ya kukangana (μ) imasinthidwa ndi kutentha, mtundu uliwonse wa brake pad chifukwa cha zipangizo zosiyanasiyana ndi curve yosiyana ya coefficient ya kukangana, kotero ma brake pad osiyanasiyana adzakhala ndi kutentha kosiyana kogwirira ntchito, Ndipo kutentha koyenera kogwirira ntchito, izi ndi zomwe aliyense ayenera kudziwa akagula ma brake pad.
Kusamutsa mphamvu yotsekera
Mphamvu yomwe imagwiritsidwa ntchito ndi piston ya brake caliper pa brake pad imatchedwa Pedal Force. Mphamvu ya dalaivala woponda pa brake pedal ikakulitsidwa ndi lever ya pedal mechanism, mphamvuyo imakulitsidwa ndi vacuum power boost pogwiritsa ntchito mfundo ya vacuum pressure difference kuti ikankhire brake master pump. Kupanikizika kwamadzimadzi komwe kumaperekedwa ndi brake master pump kumagwiritsa ntchito mphamvu yotumizira madzi yosagwedezeka, yomwe imatumizidwa ku sub-pump iliyonse kudzera mu chubu cha brake, ndipo "mfundo ya PASCAL" imagwiritsidwa ntchito kukulitsa kupanikizika ndikukankhira pisitoni ya sub-pump kuti igwiritse ntchito mphamvu pa brake pad. Lamulo la Pascal limatanthauza kuti kupanikizika kwamadzimadzi kuli kofanana kulikonse mu chidebe chotsekedwa.
Kupanikizika kumapezeka pogawa mphamvu yogwiritsidwa ntchito ndi dera lopanikizika. Ngati kupanikizika kuli kofanana, tikhoza kukwaniritsa mphamvu yowonjezera mphamvu mwa kusintha gawo la dera logwiritsidwa ntchito ndi lopanikizika (P1=F1/A1=F2/A2=P2). Pa makina oletsa mabuleki, chiŵerengero cha pampu yonse ndi kupanikizika kwa pampu yaying'ono ndi chiŵerengero cha dera la pistoni la pampu yonse ndi dera la pistoni la pampu yaying'ono.
