A disc brake for a vehicle, wherein an anti-rattling member, placed between a brake pad and a stationary or fixed member for retaining the same with the object of preventing rattling of the brake pad, is provided with a positioning portion integrally formed. The positioning portion of the anti-rattling member for facilitating mounting of the brake pad is disposed in such a position that when the brake pad is mounted (or inserted) into the stationary member from a direction parallel to the friction surface thereof the positioning portion contacts the lateral side of the brake pad for being able to position the brake pad in the circumferential direction of the disc motor. Shifting of the brake pad from this status in the perpendicular direction to the friction surface thereof will make the brake pad exactly engage with the torque receiving arm of the stationary member.

Anti-rattle and positioning member for a disc brake pad

In a type of a disc brake wherein a pad assembly is movably retained, in a mormal direction to the disc rotor surface, by a supporting member, an anti-rattle spring, interposed between the pad assembly and the supporting member, for biasing the pad assembly in a parallel direction to the friction surface thereof, made of stainless steel and being extended a part thereof along the contour of the contacting surfaces between the pad assembly and the supporting member to be interposed therebetween.

Anti-rattle spring member for a disc brake pad

A disc brake used in a car wherein a friction pad is urged onto the disc surface to restrain the movement of the disc, which disc brake, for facitating the mounting of the friction pad, is provided with (1) a backing plate of the friction pad having a notch sandwiched by two projection portions, an upper, and a lower which is smaller than the upper in projected length, on opposite upper end corners of the pad for being fitted into by a guide rail formed on a stationary member in order to allow the friction pad to slidably move in a normal direction to the disc surface; (2) a guide rail having a recess on one part thereof for allowing the lower projection portion formed smaller on the lower side of the notch to pass in a normal direction to the guide rail but not allowing the upper projection portion formed larger on the upper side of the notch to pass in the same direction; and (3) an anti-rattle spring comprising a flat body portion, an upper holding down pawl, a flange portion extending perpendicularly from the body portion, and a lower resilient pawl, which is easy to be incorporated into a complete disc brake assembly and efficient in preventing the rattling of the brake assembly.

Car disc brake improved in friction pad mounting

A seal cap assembly for a reservoir casing comprises a first seal cap having an annular thick rim portion detachably secured over the upper opening of the casing and a vertical expansible diaphragm formed in a piece with the inner periphery of the rim portion to be disposed within the casing and a second cap assembled with the thick rim portion of the first cap to facilitate removal of the cap assembly from the casing by a pushing force given to the second cap.
