Abstract: A disc brake of a type having a pair of main and auxiliary guide pins for guiding a caliper in the axial direction of a rotor. The main guide pin is secured to a support while the auxiliary guide pin is removably screwed to the caliper. For replacing a pair of friction pads, the auxiliary guide pin is removed and the caliper is turned round on the main guide pin to expose the friction pads to the outside to permit access thereto.

Abstract: This invention in general relates to a disc brake having a caliper attached to a support secured to a structural part of a vehicle or an attachment thereto to brake the vehicle by causing the members of the caliper to press friction pads against both sides of a disc rotor which is connected to the vehicle, and, more particularly to an improvement in the disc brake of such a type effected by removing the protrudent parts that have conventionally been provided on the front of the support confronting the disc rotor and by thus making the support into a shape that permits insertion of the disc rotor through the front thereof for easy mounting of the disc brake on the vehicle. The improved construction of the disc brake is particularly suitable for use in large vehicles.

Abstract: A disc brake of the floating caliper type has a pair of laterally spaced guide pins each slidably engageable at one end within a boot provided in a receptor hole in a caliper and rigidly secured at the other end to a support plate for the caliper. For facilitating the replacement of friction pads, displacement between the support plate and one of the guide pins is provided so that in replacing the friction pads, it is only necessary to loosen one of the guide pins and then to rotate the caliper about the other guide pin.

Abstract: A device for guiding a caliper in a disk brake including a portion of the disk brake which is fixed, a caliper body and a sliding sheet having a high degree of resistance to corrosion which is fixedly placed on a sliding surface between the fixed portion of the disk brake and the caliper body to thereby avoid entry of dusts, muddy water, and salt containing snow into the sliding portion, thus maintaining a proper braking performance. The sliding sheet may be made of stainless steel.

Abstract: An antiskid device is provided having an electromagnetic valve which operates when actuated to control a modulator for modulating the braking pressure applied to the wheel cylinders. The valve is actuated only when a signal, indicating a skid condition, occurs simultaneously with the brake pressure in the wheel cylinders being above a predetermined minimum.

Abstract: A pad clip device is provided comprising a U-shaped resilient spring, one portion of which is formed as a loop attached to the backing plate and having another portion extending beyond the plate to indicate the wear of the brake lining.

Abstract: A negative disc brake comprising a cylinder assembly having a thrusting mechanism wherein a thrusting force of an actuating spring is normally transmitted to a thrusting piston through an actuating piston and an adjustment screw which is in screwed engagement with the actuating piston; the thrusting piston normally pushes one friction pad against a rotor; however, when a fluid pressure is applied, the actuating piston moves against the thrusting force of the actuating spring in the direction of taking off the brake; and a caliper assembly having a reaction member which pushes another friction pad against the opposite side of the rotor by a reaction force resulting from the thrusting force exerted on the other friction pad to push it against the rotor in the brake applying action of the thrusting mechanism, the caliper assembly and the cylinder assembly being arranged as independent components mountable and dismountable separately from each other.

Abstract: The present invention relates to a floating caliper disc brake particularly used for large vehicles and industrial machineries, in detail, wherein a pair of left and right pins fixed to a support are arranged to guide inner and outer friction pads towards a disc and are removable to replace said friction pads as required, therefore, simplifying exchange of friction pads, and a pair of the pins are formed separately to receive the braking torque generated on the respective inner and outer friction pads so as to minimize strength of individual pin.

Abstract: A sealing boot for hydraulically or pneumatically operated equipments comprising an external portion which is pressed by a resilient ring into fitted engagement with a circumferential groove provided in a cylinder body, an internal portion which is tightly attached to the outer edge of a piston and a flexible portion which connects said external portion to said internal portion, the external portion being provided with a recess which is arranged in the direction of the width of the external portion to form a continuous curve.

Abstract: An antiskid control system for vehicles which prevents the vehicle body from making irregular turns due to locking of wheels when the brake is applied. The brake pressure is reduced when the commencement of a locked state of the wheels is detected. On the other hand, a minimum value of the wheel velocity is memorized; the memorized value is compared with the wheel velocity; and through this comparison, the time for stopping the brake pressure reducing action is determined.

Abstract: A single-cylinder, suspended caliper type disc brake includes a caliper assembly comprising an acting member disposed on one side of a disc and a reacting member on the opposite side thereof. A slot or an aperture is provided in the head portion of the caliper which straddles the periphery of the disc. The slot extends horizontally and parallel to a tangent of the disc, being located radially outwardly of the tangent. A fixed arm or bracket extends horizontally in the rotational direction of the disc and is inserted into the slot or aperture and supports the caliper assembly for guided movement in the axial direction of the disc.

Abstract: A disc brake has friction pads which are supported by and guided through sockets provided in the legs of a fixed support which are positioned on both sides of a disc, while the head portion of the fixed support straddles the disc and connects the two legs. A caliper assembly has acting and reacting parts provided on opposite sides of the disc and a head portion connecting the acting and reacting parts and formed with a recess. The head portion of the fixed support extends into the recess of the caliper. A single bolt or pin, mounted in the head portion of the caliper extends through an aperture or bore in the head portion of the fixed support, or a single bolt or pin, mounted in the head portion of the fixed support, extends through an aperture or bore in the head portion of the caliper and serves as the sole support for the caliper assembly.
