Measure the disc thickness at over four
points.
If any of measured points is below the wear
limit, replace the brake disc with new one. 1.

Disc Run-Out
Install the dial gauge on the side of brake disc
and measure the run-out while rotating the
brake disc.
If the measured value exceeds the limit,
replace the brake disc with new one.
Otherwise, it may cause the pedal vibration
and shimmy when braking. 1.

Check the brake force with below procedures:
Count the number of the clicks (notches)
when pulling up the parking brake with 19 kg
of force.
If the clicks are over or below the specified
value, adjust the clicks to the specified value
with the parking brake adjusting nut.
Check the parking brake force afte
r
adjustment. 1.

Specified notches5
If the parking brake force is not enough,
check the parking brake lever and cable.
Replace the components if needed. 4.
Never park the vehicle only with the parking
brake on the stiff hill. It may cause roll down of
the vehicle due to release of the parking
brake. Place the wheel chocks under the
wheels. Parking Brake ▶

1. OVERVIEW
Even though a driver cuts off the power, while driving, the vehicle continues to move due to the law of
inertia. Therefore, a braking device is needed to stop the vehicle. The brake system normally uses the
frictional discs that converts the kinetic energy to the thermal energy by frictional operation. The brake
system consists of the brake disc (front wheel), brake disc or drum (rear wheel), parking brake
(mechanical type), master cylinder, booster, pedal and supply lines (pipes and hoses).
Hydraulic Brake ▶
Brake Pedal ▶This system uses the leverage effect and
Pascal's principle. When depressing the brake
pedal, the pedal pressure is increased by
booster and is delivered to master cylinder to
generate hydraulic pressure. The hydraulic
pressure generated by the master cylinder is
delivered to the brake caliper through the brake
pipes or hoses. This hydraulic pressure pushes
the brake calipers, accordingly the caliper pads
are contacted to brake disc to generate the
braking force.
Brake pedal uses the leverage effect to apply
bigger force to the brake master cylinder.

Braking distance & stopping distance ▶
Stopping distance = free running distance + braking distance
What is stopping distance?
A certain distance (free running distance + braking distance) is needed from the moment an obstacle
appears ahead until you bring your vehicle to a complete stop. This is called as stopping distance.
What is braking distance?
Tire slip occurs until the vehicle stops completely when the the brake is applied.
This slip is what we call a braking distance.
What is free running distance?
The free running distance is the time from the driver sees the obstacles and begins to prepare for
depressing the brake pedal until the moment the brake pedal is depressed.
