Disassembly And Maintenance Of Brake; Section 11 Brake - ZONGSHEN ZS250GY-3 Service Manual

Motorcycle usually needs to decelerate and stop during riding,so brake is used to make resistance
to wheel to achieve that purpose.For normal motorcycles,front brake is operated by right hand and rear
brake is operated by right foot.However,among some motorcycles with automatic clutch,such as moped
or scooter,the rear brake can be operated by left hand.The brake of motorcycle consists of drum brake and
disc brake.This motorcycle adopts front disc brake and rear drum brake.
1 Structure and working principle of brake
Disc brake consists of mechanism type and
hydraulic type.At present,hydraulic brake is
in common use on motorcycle.The hydraulic
brake normally consists of brake handle(brake
pedal),main oil reservoir,reserve oil reservoir(The
reserve oil reservoir and main reservoir are usually
integrated),brake caliper,brake disc and brake
oil pipe.When operating brake,brake handle
compresses the main oil reservoir,which enhances
the pressure in hydraulic pressure system,drives
the main piston in brake caliper and tighten the
friction pieces on brake disc.Therefore,the brake
disc fixed on wheel can get the braking power.The
characters of disc brake is soft working ,automatic
cleaning and hard to lose control.
