Abstract: A disc brake assembly having a carrier having a first formation on an inboard surface thereof and a caliper slideably mounted to the carrier having a second formation that is proximate to the first formation in use. The relative positions of the first formation and the second formation may be indicative of an amount of wear of a brake friction element and/or a rotor.

Abstract: An Oldham coupler assembly for transferring rotary power between two shafts in an imaging device. The Oldham coupler includes an input plate and an output plate made of plastic and a star plate made of metal moveably coupled to and positioned in between the input plate and the output plate. A plastic retraction spline assembly is slidably retained in the output plate and engages with a drive member in an imaging unit. The location of the retraction spline assembly on the output plate allows for an increased diameter leading to increased torsional stiffness. The input plate includes gear teeth integrally molded into the outer circumference thereof helping to decrease the overall width of the Oldham coupler. Pairs of wheels are fastened to inner faces of the input and output plates and used to moveably couple the star plate to the input and output plates.

Abstract: A brake rotor for a vehicle that includes an easy to view accurate visual inspection system. The brake rotor includes at least one annular disk including inboard and outboard planar brake contact surfaces and at least two visual wear indicators formed as circular depressions in at least the outboard brake contact surface within the outer brake contact region. These visual wear indicators include a first wear indicator that has a depth that corresponds to a predetermined minimum useable thickness of the outboard planar brake contact surface and a second wear indicator that has a depth that corresponds to an intermediate useable thickness of the outboard planar brake contact surface. Thus, the difference in wear from the elimination of the second wear indicator compared to the first provides an indication of the remaining acceptable service life of the rotor.

Abstract: In one example, the disclosure is directed to a method of determining a length of a wear pin in a brake assembly. The method includes obtaining an input image of a portion of the brake assembly, such as with a camera. The input image includes the wear pin and a reference object, and the reference object has a known dimension. A processor may determine, based on the input image, an image dimension of the reference object. The processor may determine, based on the input image, an image dimension of the wear pin. The processor may further determine, based on the image dimension of the reference object, the image dimension of the wear pin, and the known dimension of the reference object, an estimated measurement of the dimension of the wear pin.

Abstract: A method to inspect and compensate for wear on a brake shoe of a railcar brake system includes removing the railcar brake shoe from a brake head of the railcar brake system, placing a brake inspection device between the brake head and a railcar wheel, applying brake load, measuring a gap formed between the brake head and the wheel, measuring the thickness of a stop block of the brake inspection device positioned between the brake head and the railcar wheel, determining an adjustment distance as the difference between the gap measurement and the thickness of the stop block, and adjusting an end extension of the railcar brake system in accordance to the determined adjustment distance.

Abstract: Systems and methods for estimating the cooling time of a brake assembly are disclosed. Systems are provided comprising a processor, a tangible, non-transitory memory configured to communicate with the processor, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations comprising receiving, by the processor, a first temperature of a brake assembly at a first time, receiving, by the processor, a second temperature of a brake assembly at a second time, wherein the second time occurs a fixed period after the first time, determining, by the processor, a temperature decay coefficient (“α”) of the brake assembly based on the first temperature and the second temperature and calculating, by the processor, an estimated total time to cool the brake assembly to a predetermined temperature based on the first temperature, the predetermined temperature and α.
