Abstract: A method and apparatus for calculating the total running clearance of a disc brake. The method includes detecting axial movement of a component of a piston assembly of the disc brake to provide data indicating the displacement of the component of the piston assembly during a braking operation, and determining an amount of displacement of the component that occurs before inboard and outboard brake pads both contact a rotor to provide a calculated total running clearance.

Abstract: a There is disclosed a battery pack comprising: a first battery cell layer comprising a structure for locating battery cells and providing a flow path for a coolant so that the coolant passes across the battery cells; a gasket of a first gasket type located adjacent a first face of the first battery cell layer; and a gasket of a second gasket type located adjacent a second face of the first battery cell layer. Each of the first gasket type and the second gasket type comprises a first side and a second side. The first gasket type comprises holes for the coolant located on the first side of the first gasket type; and the second gasket type comprises holes for the coolant located on the second side of the second gasket type. The gaskets enable the coolant to flow from a first end of the battery pack to a second end of the battery pack via the flow path.
