PAD WEAR INDICATOR
A wear indicator is provided on the inner disc brake pads. When the pad wears down to 1.5 mm (0.059 in) the tip of the wear indicator comes into contact with the disc rotor, and makes a squeaking sound as the wheel rotates. This alerts the driver to the situation.

FRICTIONAL MATERIAL OF BRAKE PADS
The brake pads materials do not contain any asbestos which is harmful to human body.
Scheme 4
- The master cylinder consists of a brake fluid reservoir chamber that stores brake fluid, and a hydraulic chamber section that converts the force applied to the brake pedal into hydraulic pressure.
- The hydraulic pressure generated in each of the two hydraulic chambers are sent to the brake caliper of each wheel through the 2 diagonally split brake circuits.
Brake Booster
The brake booster is a tandem type that uses two diaphragms.
By utilizing the differential pressure between the intake manifold vacuum and atmospheric pressure, a high braking force can be obtained even when the pedal depressing effort is small.
The brake booster is installed between the brake pedal and master cylinder. This contributes to improve the response to the brake pedal. If it fails, the brake servo effect is lost requiring a larger pedal effort, however, the braking force is still maintained.

Brake Pedal
The brake pedal is provided with a mechanism to control movement to the rear in case of a frontal collision to minimize injury to the driver's legs.
Scheme 6
If the brake pedal is pushed rearwards in case of a frontal collision, the brake pedal comes in contact with the catcher.
Scheme 7
If the brake pedal is pressed further, the brake pedal will come apart from the pedal side bracket.
The brake pedal will move along the brake catcher.
By letting the brake pedal to move down along the catcher, the rearward movement of the brake pad is controlled.
