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 Figure 5.1.
Pedal movement pushes the piston of the
master cylinder by means of the push rod, which
converts pedal effort into hydraulic pressure.
