Brakes and Traction Control: Description and Operation

GENERAL INFORMATION

The brake system has high reliability and durability, and provides an exceptional braking performance.

FEATURES

IMPROVED BRAKING PERFORMANCE

- In addition to the 10-inch through bolt type single brake booster, the small and long stroke-type master cylinder is adopted to provide rigidity, to reduce weight, and to secure the assist force.
- Brembo(TM) 18-inch 4-pot front ventilated disk brakes and Brembo(TM) 17-inch 2-pot rear ventilated disk brakes are adopted to provide stable braking force and improved braking feel.
- To the front, two-piece structure brake disk is installed.[ GSR: Option, MR: Standard]

IMPROVED STABILITY

- Front- and rear-wheel X-type brake line layout is used.
- The brake pedal retreat suppression mechanism that suppresses the retraction of brake pedal surface upon a frontal collision is adopted.
- To the front brake and rear brake, the brake pads with audible wear indicator are adopted which warn the driver of the wear limit.
- The 10-inch single brake booster with brake assist mechanism, which determines an emergency exists based on the brake pedal depression speed and force and provides the maximum braking force, has been adopted.

BRAKE ASSIST MECHANISM





When the driver suddenly applies the brake, generally there is a tendency that a driver depresses the brake pedal quickly but not strong enough, or depresses the pedal once but reduces the depression force immediately after that. In this case, a sufficient braking force cannot be obtained, resulting in a longer stopping distance.
This brake booster with brake assist mechanism recognizes the status as emergency when the driver depresses the brake pedal quickly; it increases the assist force to the maximum value and maintains the output value of the brake booster to activate ABS.
Even if the driver reduces the depression force immediately after depressing the brake pedal quickly, this brake booster maintains the status where the maximum assist force is being applied until no depression force is applied to the brake pedal.
