8. ADVANTAG E S O F H Y DRAULI C BRAKES ▶ Equa l brak i ng effort to a l l the four whe e ls ▶ Less rate of wear ▶ Better stopping power than the other brakes

9. DISA D VANTAG E S O F H YDRAULIC BRAKES Complex construction Even slight leakage of air into the breaking system m a kes i t usele s s. More maintenance than other system

10. DIS C BRA K ES A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a rotor to create friction. T he p i sto n i n turn s q ueezes two bra k e pads a g a i nst the d i s c (rotor ) , which is attached to wheel, forcing i t to slo w down or s top.

11. DRU M BRAKES ▶ The dru m br a ke has a m etal brak e dru m that e n cl o s e s the brak e as s embly a t each wheel. ▶ Two curved brak e shoes expand o u tward to slo w o r sto p the dru m wh i ch rotat e s w i th the whe e l.
