Abstract
An in-line roller skate brake having a progressively engagable braking surface and a method for applying such a brake are provided herein. A brake embodying the present invention includes selectively located relief apertures that enable a skater to controllably collapse and deform the brake pad such that the braking surface engages the skating surface from the trailing edge forwardly. In the preferred embodiment, a pair of relief apertures each having a substantially crescent shaped, cross-sectional configuration extend from the braking pad braking surface upwardly into the braking pad. The relief apertures further provide a means for controlling the abrasive wear on the rear portion of the brake pad so that the braking surface will engage the skating surface from the trailing edge forward to the leading edge throughout its use life.
