Abstract: A steering system which is capable of being controlled by a redundant brake system, which includes a primary brake control module, a secondary brake control module, and a plurality of brake units controlled by the primary brake control module or the secondary brake control module. There is at least one hydraulic motor connected to a component of the steering system, and the fluid pressure in the hydraulic motor is controlled by the secondary brake control module. The wheels of the steering system are configured to make a right-hand turn when the secondary brake control module operates the hydraulic motor during a first mode of operation, and the wheels of the steering system are configured to make a left-hand turn when the secondary brake control module operates the hydraulic motor during a second mode of operation.

Abstract: A disc brake for a motor vehicle includes a rotor mounted to a wheel and rotatable about a first axis therewith; a pair of parallel-spaced pins removably mounted to the vehicle chassis so as to extend in a direction generally parallel to the first axis; a pair of brake shoes having slots for receiving the pins on either side of the rotor so as to place brake linings respectively mounted on the pins in opposition with complementary annular friction surfaces on either side of the rotor; and a caliper slidably supported by the two pins so as to straddle the rotor and both brake shoes, respectively. The slots of the brake shoes are defined in part by a finger configured to deflect responsive to a brake load and the deflection of the finger enables the sequential engagement of the brake shoes against the pins.
