Disk brake devices

A disk brake device comprising:

• at least a pair of brake disks arranged and constructed to be disposed so as to interface with a right side vehicle wheel and a left side vehicle wheel, where each brake disk further includes;
• a rotational axis, and
• a inner brake disk surface, and
• an outer brake disk surface,
• a right pair of pads and a left pair of pads arranged and constructed to apply braking forces against respective brake disks;
• the right pair of pads includes a right inner pad and a right outer pad respectively disposed in sliding contact with the inside brake disk surface and the outside brake disk surface of the brake disk of the right side vehicle wheel;
• the left pair of pads includes a left inner pad and a left outer pad respectively disposed in sliding contact with the inside brake disk surface and the outside brake disk surface of the brake disk of the left side vehicle wheel;
• each of the pads includes:
• a friction member arranged and constructed to be pressed against the corresponding brake disk;
• a twisting compliant section provided in each of the corresponding friction members, in which each of the twisting compliant sections extends along a line inclined relative to a radial direction of the corresponding brake disk in order to facilitate the twisting of the pad about the twisting compliant section, and in which each of the twisting compliant sections is made of a material that is more flexible than a material of a remaining part of the friction member;
• the twisting compliant sections of the right inner pad and the left inner pad are respectively inclined in opposite directions to the twisting compliant sections of the right outer pad and the left outer pad;
• and
• the twisting compliant sections of the right inner pad and the left inner pad are inclined in substantially the same direction with each other.
