摘要： A disc brake rotor has a plurality of radial groves on its opposite sides that are equiangularly spaced. The angular interval of the grooves on one side is different from the angular interval of the grooves on the other side, so that the vibrations of two different modes caused by the grooves on the opposite sides interfere with each other during braking operation. By thus suppressing stationary wave mode vibrations, the disc brake rotor prevents production of brake squeals.

摘要： A hydraulic pressure control valve for a dual-circuit brake system of a vehicle. In this control valve a pair of valve pistons for controlling the braking hydraulic pressure delivered to each of rear wheel brakes are disposed in a housing parallelly and imparted with biasing force directed inwards of the housing by one biasing device. The biasing device is assembled or set within a cover of cup-shape such that the biasing device has been given a preload substantially equal to a biasing force necessary for the control valve before the cover is fixed to the valve housing. The biasing device includes a swingable guide rod attached at one end thereof to the cover with a pivot pin, a sliding member slidably fitted on the guide rod, and a compression spring disposed between the sliding member and a free end of the guide rod for biasing the sliding member toward the pivoted end of the guide rod. The guide rod is provided with a projection for stopping axial movement of the sliding member due to the biasing force of the spring. When the cover is attached to the valve housing the sliding member abuts on ends of the valve pistons and consequently is separated from the projection for transmitting the biasing force of the spring to the valve pistons.

摘要： A brake booster of stroke-enlarging type which includes a power piston moved in accordance with the difference of pressure on opposite sides thereof, a control piston having therein a control valve for controlling the pressure difference and slidably fitted in a central bore of the power piston, an anti-backdown transmission mechanism disposed between the two pistons, a reaction lever abutted at an output portion thereof on an output member and, at a pair of input portions located on opposite sides of the output portion, on the control piston and the anti-backdown transmission mechanism respectively, and a return spring backwardly biasing the power piston. The anti-backdown transmission mechanism transmits the output force of the power piston to the reaction lever and the reactionary force of the reaction lever to the power piston in an initial operation stage of the booster, and after an advancing of the power piston in relation to the control piston by a predetermined amount it transmits the reactionary force of the reaction lever not to the power piston but to the control piston. An abutting portion is disposed on the power piston for abutting on the front side of the anti-backdown transmission mechanism for retracting the same to the original position together with the power piston which is forcibly retracted by the return spring.
