Abstract: A pad clip 40 includes a U-shaped portion 46 which can be engaged with a guide projection 16 provided in a support 14. On one side of the U-shaped portion 46, a first spring portion 74 is continuously connected to a second spring portion 64. The first spring portion 74 includes a curved portion 76 and a leading end contact portion 82, such that the leading end contact portion 82 energizes a friction pad 20 outwardly in the rotor radial direction. The second spring portion 64 is protruded and curved in the rotor peripheral direction to thereby provide a projection shape. The protrusion top portion 70 of the second spring portion 64 is in contact with the friction pad 20, and the spring upper end portion 66 and lower end portion 68 of the second spring portion 64 are respectively in contact with the support 14, thereby energizing the friction pad 20 in the rotor peripheral direction.

Abstract: A brake actuator and slack adjuster subjected to axial vibration includes a slack adjusting mechanism circumferentially engaging a brake actuating mechanism. A circumferential elastomer bushing is disposed about the brake actuating mechanism for damping axial vibrations experienced by the slack adjuster. One washer has a recess sized to receive and seat one end of the bushing while a shim washer is located at the other end of the bushing and against a bearing race of the slack adjuster.

Abstract: The present invention relates to a hydraulic brake system with slip control, including a braking pressure generator which is connected hydraulically to at least one wheel brake by way of a main pressure line, a return line connected to the wheel brake and in communication with a pressure fluid collecting device, an auxiliary-pressure pump having an auxiliary-pressure line which is connected to the braking pressure generator, and at least one pressure modulation valve acting in the main pressure line and in the return line to close or keep open the pressure fluid passage in the main pressure line and the return line. An orifice is arranged in the main pressure line between the pressure modulation valve and the wheel brake, and an unimpeded hydraulic passage between the main pressure line and the wheel brake is provided in a first switch position, and the orifice limits the pressure fluid passage in the main pressure line leading to the wheel brake in another switch position.

Abstract: A disc rotor formed of flaky graphite cast iron in which the natural frequency of the disc rotor is set by the graphite length in the flaky graphite cast iron structure.For preventing resonant vibrations ascribable to the self-excited vibrations of the component parts of disc brakes, such as pads, the natural frequency of the disc rotor are shifted from the frequency of excited vibrations of the component parts of disc brakes, such as pads.
