POWER BRAKE UNIT FUNCTION [ABS]
id041100100816
• A 10-inch, single diaphragm type power brake unit has been adopted, achieving compatibility between high braking performance and excellent brake feeling.
• With the adoption of a brake assist function, brake system (including ABS during emergency braking) effectiveness has been further improved.
-
― The brake assist function operates by aiding braking operation during emergency braking or other times when a high amount of brake power is required.
― Inexperienced drivers or drivers who panic during emergency braking may apply the brakes quickly but without sufficient force, or they may apply sufficient force but cannot maintain it for a continuous period. In these cases, the normal vehicle braking performance cannot exert sufficient force.
― The brake assist function determines, based on brake pedal depression speed and force, if emergency braking is occurring. If it occurs, the power brake unit applies maximum braking power.
• The structure of the brake assist function, built into the power brake unit, is simple and mechanical, to ensure a high level of reliability.
-
Note
-
• When the brake pedal is depressed, the following effects may be felt. These are normal effects of the brake assist operation and do not indicate an abnormality.
-
― When the brake pedal is depressed strongly or depressed at higher speeds, the pedal will feel softer but the brakes will be applied strongly.
― When the brake pedal is depressed strongly or depressed at higher speeds, a clicking noise from the brake booster may be heard.
• The brake assist equipment does not supersede the functionality of the main braking system.
