Rear disc brakeer（

Principle of disc breacker：liquid can’t be compressed，so power can be
past by a go-between of liquid。
Oil punp body：

：
When brakeer is stepped down，the press passes by the shaft,the piston in
the oil pumpbody moves in the same direction of the press，when the bowl of
the piston goes through the hole of resupply，the piston presses the liquid in the
oil pump body，the liquid compressed passes the power to the brake tube by the
brakeer tube。When the pressure disappeares，because of the elasticity of the owl
spring the piston shrinks back to the starting pisition 。
The structure of this disc brakeer comp is “sole piston sole brakeer tub”,brakeer
tub connects to the seat of brakeer clamp directly, when the disc is pressed
downb by the pressureof the piston,it push es the brakeer shoe closing to the
disc, it makes the brakeer shoe touch the disc evenly, the brake power produced
by the rub slows down the motor, this is brakeing.
