Abstract: A disc brake system comprises a mounting hub and at least one disc supported by the mounting hub. The mounting hub has a center portion and an outer portion substantially perpendicular to the center portion and defines a central axis extending perpendicular to the center portion. A plurality of grooves comprising a U-shape are defined within the outer portion and are spaced radially about the central axis. Each of the grooves extends axially relative to the central axis. A bearing is disposed in each of the plurality of grooves and operatively connects the mounting hub and the disc such that the bearing rotates about a bearing axis and moves axially within the groove in response to axial movement of the disc.

Abstract: An actuator for an electro-mechanical-brake motor assembly includes a housing surrounding a rotatable motor shaft presenting a longitudinal axis. A spring is non-rotatably supported on the housing. A latching device is non-rotatably supported by the housing. The latching device has a plurality of teeth. A latch gear is non-rotatably supported on the rotatable motor shaft and circumscribes the longitudinal axis and presents a plurality of axially facing angled teeth presenting a meshing engagement with the teeth of the latching device. The latching device is axially movable relative to the housing in response to magnetic force generated by the electric coil.

Abstract: The invention provides a brake caliper backdrive apparatus and method of backdriving a brake caliper. The apparatus includes a brake caliper, a motor including a shaft operably attached to the brake caliper and, a biasing member operably attached to the shaft. The biasing member backdrives the motor thereby releasing the brake caliper. The method includes rotating a shaft to clamp the brake caliper, storing energy in a biasing member responsive to the shaft rotation, and reversing the shaft rotation using the stored energy.

Abstract: The present invention provides a sensor system for detecting lining wear and fluid level in a dry interface corner actuator for a single wheel brake including a reservoir assembly. The reservoir assembly includes a reservoir for containing fluid for the actuator and a sensor assembly positioned in the reservoir having a single set point to indicate both low reservoir fluid level and a need for brake lining replacement.

Abstract: The present invention provides a reservoir cap and bleed mechanism for use with the fluid reservoir of a dry interface corner actuator. The reservoir cap and bleed mechanism displaces a portion of the reservoir volume during filling and provides a diaphragm to maintain a fill reservoir volume during operation. The fluid reservoir can be bled and filled to the desired brake fluid level through a sealable passage in the reservoir cap assembly without removing the reservoir cap.
