A disc brake having a ball-in-ramp actuator retained in a caliper for supplying a piston with a static clamping force to move first and second friction members into frictional engagement with a rotor to effect a parking brake application. The clamping force is transmitted from the ball-in-ramp actuator into the piston through an adjustment screw mechanism. The disc brake being susceptible to a thermal expansion and a thermal contraction and as a result the effect of the clamping force applied to bring the first and second friction members into engagement with the rotor may change during a time period that the parking brake application is initiated until it is terminated. The adjustment screw mechanism is characterized by a spring that is compressed by the actuation force to initiate the parking brake application that expands and contracts to compensate for the thermal contraction and expansion of the disc brake such that the effect of the static clamping force remains substantially the same for the duration time of the parking brake application.

The screen door of claim 21 wherein said hinge allows said screen frame to translate vertically while said screen frame rotates about a pivoting axis of said hinge, and wherein said wing causes said screen frame to be elevated when said wing rides up said slope and causes said screen frame to be lowered when said wing rides down said slope. 23. A pivoting screen door receivable within a patio doorway in a manner selectively occluding an opening of the doorway, the pivoting screen door comprising in combination: a screen frame; a screen panel at least partially bordered by said screen frame; means to pivotably attach said screen frame to the patio doorway; means to bias said door toward a closed position spaced from an open position, said closed position at least partially occluding the opening, said closed position occluding a greater portion of the opening than said open position; means to detain said door in an at least partially open position said detaining means sufficiently neutralizing said biasing means to allow said door to remain in said at least partially open position; and wherein said screen door further includes a means to elevate said door when said door moves away from said closed position and toward said open position. 24. The screen door of claim 23 wherein said detaining means is oriented to detain said door when said door is in said open position. 25. The screen door of claim 24 wherein said biasing means includes a diagonally sloping surface supporting at least a portion of a weight of said screen frame and said screen panel, said sloping surface oriented to apply a rotational force on said screen frame tending to cause said screen frame to rotate about a pivoting axis of said hinge t
