Mfundo yolondola yogwirira ntchito ya pampu ya brake ndi iyi:
Pompu ya mabuleki ndi gawo lofunika kwambiri la mabuleki a chassis, ntchito yake yayikulu ndikukankhira brake pad, brake pad friction brake drum. Chepetsani liwiro ndikuyimitsa. Pambuyo poti brake yakanikiza, master pump imapanga thrust kuti ikanikizire mafuta a hydraulic ku sub-pump, ndipo piston mkati mwa sub-pump imayamba kuyenda pansi pa mphamvu yamadzimadzi kuti ikankhire brake pad.
Bulaki ya hydraulic imapangidwa ndi pampu ya brake master ndi thanki yosungiramo mafuta a brake. Amalumikizidwa ku pedal ya brake kumapeto kwina ndi chubu cha brake kumbali inayo. Mafuta a brake amasungidwa mu pampu ya brake, ndipo pali malo otulutsira mafuta ndi malo olowera mafuta.
1. Woyendetsa galimoto akamaponda pedali ya brake, pisitoni ya master pump imapita patsogolo kuti itseke dzenje la bypass. Kenako, kuthamanga kwa mafuta kumawonjezeka patsogolo pa pisitoni. Kenako kuthamanga kwa mafuta kumasamutsidwira ku brake pump kudzera mu payipi;
2. Pamene brake pedal yatulutsidwa, pisitoni ya master pump imabwezeretsedwanso pansi pa mphamvu ya mafuta ndi kasupe wobwerera. Pambuyo poti mphamvu ya braking system yatsika, mafuta ochulukirapo amabwerera ku chidebe cha mafuta;
3, kuletsa kwa mapazi awiri, mphika wamafuta kuchokera pa dzenje lolipirira kupita kutsogolo kwa pistoni, kotero kuti mafuta omwe ali patsogolo pa pistoni amawonjezeka, kenako pakuletsa, mphamvu ya kuletsa imawonjezeka.
