Brek pedal i save wok long rot bilong wanpela 'hydraulic braking system'. Speseli:
Fos Konvesen na Transmisen: Taim draiva i presim 'brake pedal', wanpela 'precision pedal mechanism' i save senisim strong bilong lek i go long 'mechanical energy'. Dispela strong i save kirapim piston insait long bikpela silinda.
Haidrolik Konvesen: Muvmen bilong piston i senisim presa bilong wara bilong brek. Dispela senis bilong presa i wok olsem wanpela 'relay', na i save salim i go long ol 'brake line' i go long ol 'brake' long ol wil.
Brek Aktuesen: I dipen long kain brek (disk o dram), haidrolik presa i save kirapim ol samting olsem brek kalipa o brek su-na fosim ol long wok wantaim brek disk o dram bilong wil. Friksen we i kamap namel long ol dispela samting na wil i save kamapim 'deceleration'.
Ol gutpela samting olsem Anti-lock Braking System (ABS) i save strongim sefti bilong draivim ka long rot bilong givim gutpela kontrol long taim bilong 'emergency braking'.
