<p>A brake surface is provided for slide coaster sleds in which the brake surface is configured to be an elongated surface of much greater length relative to the width. The braking surface is particularly useful for use on wet slide surfaces because the foremost sections of the brake surface remove the moisture at the brake-slide interface and dry the surface through frictional contact. Therefore, the following brake portions of about two-thirds of the length are available to bring about effective braking action. Preferably, the elongated brakes are formed in a U-shape in cross section with a central groove for containing moisture. Also, it is preferred to have two spaced apart brake surfaces positioned on opposite sides of the longitudinal center line of the sled.</p> |
