A system and method are provided for continuous monitoring and controlling of aircraft braking that can reduce brake wear and aircraft operating costs through the retention of carbon brake powder from the brakes or addition of carbon powder in a device mounted with respect to the brake disk stack. The use of carbon powder reduces brake wear by providing small particles between the brake disks, acting as a buffer between the brake disks when the brake stack is clamped together. Moreover, when carbon powder or small particles are used at application, such use reduces the roughness of the carbon surface and reduces the number of large particles from braking off the carbon surface, thereby reducing brake wear. Adaptive or selective braking may be used in conjunction with carbon powder to further reduce carbon brake wear.

A tool for retracting pistons into cylinder bores is disclosed. A plurality of centering cones are provided to engage with a multitude of piston sizes and configurations. A user selects an appropriately sized centering cone and engages the selected centering cone with a spring loaded distal pusher portion of said tool. A female threaded collar and spreader plate combination receives a male threaded thrust bolt. The male threaded thrust bolt carries the spring loaded distal pusher portion. The spreader plate is pressed against a face of the caliper assembly, and rotation of the male threaded thrust bolt by a driver, such as a ratchet wrench or impact gun, applies inward and rotating forces from the spring loaded distal pusher portion of said tool to the piston, while separating the spring loaded distal pusher portion of said tool from the spreader plate.

A disc brake (1) for motor vehicles includes at least two brake pads (25, 26), an application unit (4) with a setting spindle (5) arranged axially in the direction of the brake pads (25, 26), and a resetting device (7) for central adjustment of the setting spindle (5) after reaching a degree of wear of the brake pads (25, 26). The resetting device (7) has a housing (8), a sensor (9), a resetting shaft (10), and an adapter (11) with a decentral output (12). In one example, the adapter (11) has a cover (13) and a chain drive (14) for to transmitting an actuating movement from the decentral output (12) to the resetting shaft (10). FIG. (1)

A tool for retracting pistons into cylinder bores is disclosed, with a narrow gap between facing pressure plates allowing use of the tool in tight places, and ratcheting spreading of the facing pressure plates causing outward moving of the pistons, enabling work to be performed, wherein movement of a threaded stud through a coupler moves a first pressure plate.

A disc brake rotor and hub assembly for a heavy-duty vehicle. The disc brake rotor and hub assembly includes a hub portion. The hub portion is receivable on, and rotatable about, an axle spindle of a heavy-duty vehicle. A rotor portion includes a disc segment, a mounting segment and a cylindrical sleeve segment connecting the disc segment to the mounting segment. A flange portion connects with the rotor portion and separately with the hub portion. Optionally, the rotor portion connects directly to the hub portion. A smallest inner dimension of the rotor portion is greater than a largest outer dimension of the hub portion to facilitate removal of the rotor portion without removing the hub portion from the axle spindle.

A hydraulic brake caliper piston/plunger tool includes a handle, a barrel with rear and front tubes, and a shaft. The handle is provided therein with a fluid reservoir and a fluid chamber, and pivotally connected with an operation lever having a plunger inserted into the fluid chamber. The shaft is attached with a piston and fitted through the rear tube, the barrel and the front tube. A return spring is fitted around the shaft in a central hole of the barrel, between the piston and the front tube. A front end of the shaft is adapted to be fitted with an accessory for a disc brake. A rear end of the shaft is adapted to be connected with a turning tool. In use, alternately depressing and releasing the operation lever enables fluid to enter the central hole of the barrel to have the piston together with the shaft moved forward.

A tool for retracting pistons into cylinder bores is disclosed, with a narrow gap between facing pressure plates allowing use of the tool in tight places, and ratcheting spreading of the facing pressure plates causing outward moving of the pistons, enabling work to be performed. One of the pressure plates is reversible to change the minimum narrow gap from a first width to a second width. In each of the orientations, the plates are movable towards and away from one another.

A disk brake for a brake disk ring of an azimuth drive of a wind turbine includes a brake housing which has two housing halves that, on opposite sides, flank receiving jaws for the brake disk ring. At least two brake pistons which hydraulically act upon friction lining carriers assigned to the receiving jaws are mounted in each housing half. At least one housing half has a cleaning channel, extending from a rear side of the housing and towards a front housing area, in which the receiving jaws and the friction lining carriers are provided.

A disc brake having an actuation mechanism, a wear adjustment mechanism that includes a manual rewind apparatus having a manual adjuster shaft; a brake caliper having a housing cavity and an inboard wall, an inboard support interface, and an outboard support interface. The inboard support interface is located within the housing cavity, outboard of the inboard wall.

A routine maintenance procedure performed in respect of a wheel of an aircraft landing gear is disclosed. Consumable brake lining material is integrated with the wheel. Re-treading or replacing the wheel tyre and inspecting or replacing the consumable brake lining material tyre are performed at the same successive intervals as part of the routine maintenance procedure. The sum volume and mass of brake material present on the aircraft may thus be reduced. Brake material providing for the demands of a maximum energy rejected take-off may be provided separately. The wheel may be made in one or two parts from carbon-fibre composite material. At least some of the brake material may be provided on an outwardly facing planar surface of the wheel.
