5.1 GENERAL DESCRIPTION
The brake system is a front two wheel braking, internal expansion, hydraulic type consisting of a
brake pedal, a master cylinder and wheel brakes.
5.1.1 BRAKE PEDAL
The brake pedal is installed through a bracket to
the frame as shown in Fig. 5.1.
Pedal movement pushes the piston of the master
cylinder by means of the push rod, which converts
pedal effort into hydraulic pressure.
