A disc brake assembly includes a rotor and a pair of friction elements which are engageable with the rotor to retard rotation of the latter. A support carries the rotor and movably disposes the pair of friction elements adjacent the rotor. An actuator is pivotally mounted on the support and is provided with a cam member to urge the pair of friction elements into engagement with the rotor as the actuator moves from a neutral position to a braking position. The actuator includes at least one friction pad which is engageable with the rotor to move the actuator from the neutral position to the braking position. An input member on the actuator is operated by a vehicle operator to control the engagement of the one friction pad with the rotor. The actuator rotates about its pivotal mounting on the support and in the direction of rotation of the rotor when it moves from the neutral position to the braking position. A frame includes a central opening for carrying the pair of friction elements and an extendible assembly is carried within the central opening by a lever. The lever is adjustable by the extendible assembly to control the position of the pair of friction elements relative to the rotor.

Disc brake and actuating lever therefor

A disc brake assembly includes a frame which is movably disposed relative to a rotor and a central opening on the frame carries a pair of friction elements facing opposite sides of the rotor. An adjuster assembly is disposed within the central opening to control the position of the pair of friction elements relative to the rotor. The adjuster assembly includes a lever pivotally engaging the frame and an extendible assembly cooperating with the lever and frame to control the pivotal position of the lever relative to the frame. An actuator extends into the central opening and is engageable with one of the friction elements and the lever. Upon operation of the actuator, the one friction element separates from the lever to engage the rotor and the frame moves to engage the other friction element with the rotor. A pawl is responsive to movement of the actuator to control extension of the extendible assembly. The extendible assembly is carried on the lever at an end remote from the pivotal engagement with the frame. The lever carries a roller which is engageable with the actuator and a U-shaped section of the lever forms a pocket to receive the roller.

Disc brake and adjuster therefor

A hitch for connecting a tow vehicle to a trailer having a toggle plate through which a steering input is transmitted into a steering system on the trailer and a braking input is transmitted into a braking system on the trailer.

Trailer hitch

A control valve for use in a tow vehicle-trailer braking system has a first bore connected to a master cylinder and a second bore with an entrance port connected to a pump in the tow vehicle for receiving a fluid under pressure, an exit port connected to a power steering control operated by the fluid under pressure, and a control port connected to a servomotor in the trailer. A first piston is located in the first bore and a second piston is located in the second bore. A lever which is located on a pivot pin connects the first piston with the second piston. When the operator applies a braking force to operate the master cylinder, the first piston receives a hydraulic force which acts on the lever to move the second piston and direct a portion of the pump fluid under pressure from the exit port to the control port to activate the servomotor brakes in the trailer.

Tow vehicle-trailer braking system

A sway control apparatus for use in a tow vehicle trailer braking system that provides a brake applying servomotor in the trailer with an independent actuation signal to attenuate oscillary forces which may develop between the trailer and the tow vehicle.
