| Outline of Final Research Achievements |
Brake pads of conventional disk brake of an automobile contact with brake disks, as a result of sliding resistance of brake caliper. This contacting loss is called brake loss, and it was assumed that 2.5 % reduction of fuel consumption by eliminating the brake loss. It is shown firstly that the brake pad can float by the brake disk rotation, if the brake pad surface has an appropriate profile. In the next, it is shown that the appropriate profile is automatically created with increasing the pad wear, if the pad has special slits. This technique is an effective tribological method, because only exchange for developed brake pad leads reduction in fuel consumption of automobile.
