| 20090288921 | REDUCTION OF PARTICULATE EMISSIONS FROM VEHICLE BRAKING SYSTEMS - A vehicle braking system reduces particulate emissions resulting from wear of the brake pad and rotor during stopping or slowing of a vehicle. The rotor includes at least one friction surface, that has an outer coating of a corrosion and wear-resistant material. This outer coating can optionally include a first layer comprising a crystalline material and a second layer overlaying and contacting the first layer and comprising an amorphous material. The first layer and the second layer can optionally have an inter-layer period of less than 10 nm such that the structure of the outer coating is that of a superlattice. A brake member that includes a friction material is mounted to a caliper on the vehicle with the friction material disposed opposite the at least one friction surface so that the friction material reversibly engages with the outer coating of the corrosion and wear-resistant material when the braking system is operated to stop or slow the vehicle. Contact between the friction material and the outer coating results in substantially reduced conversion of the friction material to dust while producing an improved coefficient of friction relative to standard braking systems. Related systems, apparatus, methods, and/or articles are also described. | 11-26-2009 |

Each pad supporting plate rests against a pressure plate, which is supported in the brake caliper, or against a brake caliper supporting surface.

| 20120103735 | BRAKING DEVICE AND METHOD FOR MANUFACTURING FRICTION MATERIAL - There is provided a braking device including a pad having a friction surface, and a disc having a friction surface sliding on the friction surface. The pad includes, in the friction surface, a plurality of hard particles tilted in the opposite direction to a direction in which the friction surface slides on the friction surface, and the disc includes, in the friction surface, a plurality of hard particles tilted in the direction in which the friction surface slides on the friction surface. Thereby, mutually pressing forces between the hard particles are increased. Additionally, the mutually pressing forces between the hard particles are increased, and consequently the distance between the friction surfaces is shortened. Therefore, a higher frictional force can be obtained. | 05-03-2012 |
| 20110162919 | Disk Brake Pad - A brake pad configured for use in a vehicle brake assembly comprises: a friction material having an outermost edge, an innermost edge, and first and second side edges extending therebetween; and a stepped portion extending along the innermost edge of friction material from the first side edge of the friction material to the second side edge of the friction material. | 07-07-2011 |
| 20120037465 | BRAKING DEVICE AND METHOD FOR MANUFACTURING FRICTION MATERIAL - A braking device is provided with a pad having hard particles on a wavelike friction surface, and a disc having a hard layer on a wavelike friction surface which slides on the wavelike friction surface. The wavelike friction surface has a groove portion in a direction in which the wavelike friction surfaces slide on each other, and the wavelike friction surface has a protruding portion which abuts on the groove. Therefore, the actual contact area between the friction surfaces having the hard members is increased, and a higher frictional force can be obtained without sacrificing wear resistance. | 02-16-2012 |
| 20100243384 | DISC BRAKE APPARATUS - The present invention is to stabilize behavior of brake pads at the time of braking of a disc brake so as to suppress generation of brake noise, and also to reduce the roll moment of the brake pads generated at the time of braking so as to suppress uneven abrasion of linings.

| 20100288589 | BRAKE LINING SET HAVING DIFFERENT COMPRESSIBILITY - The present invention discloses a brake pad set for a disc brake with a clamping device. This brake pad set comprises at least one first brake pad, which is arranged on the one side of the brake disc and a second brake pad, which is arranged on the other side of the brake disc. The brake pad set is characterized in that the friction pad of the first brake pad has a compressibility other than that of the friction pad of the second brake pad. | 11-18-2010 |
| 20120073914 | BRAKE SYSTEM AND METHOD FOR PRODUCING FRICTION MATERIAL - A brake system includes a pad having a frictional surface, and a disc having a frictional surface sliding on the frictional surface. The frictional surface includes hard particles supported elastically and a plurality of protrusions arranged along a direction in which the frictional surface slides on the frictional surface, and when the frictional surface slides on the frictional surface, particles abut respective protrusions continuously while being displaced in the direction perpendicular to the frictional surface. Thus, wear resistance can be improved Since only the vicinities of the peaks of the hard particles and the vicinities of the peaks of the protrusions abut, the hard particles do not follow irregularities of the frictional surface, and thereby the hard particles and the protrusions repeat point contact. Thus, since the distance between the hard particles and the protrusions is stabilized and the adhesion frictional force is stabilized, a stable frictional force can be obtained. | 03-29-2012 |

| 20120325598 | BRAKE LINING FOR RAILROAD CAR - A brake lining for a railroad car has a frictional surface on a brake disc that is pressed by a brake caliper. Friction bodies are pressed against the frictional surface of the brake disc and a back plate is mounted to the caliper to support the friction bodies. Each of the friction bodies is formed with a friction material which contacts the brake disc frictional surface, and has a base plate attached on the back plate side of the friction material.
