An improved small wheel disc brake for skateboards, scooters, and carts, which facilitates a heat management design to provide higher level of performance operation without brake failure thereby improving the safety of said vehicles. The disc brake (6) includes a non-metallic friction pad disc (18) which is fixed to the central aperture of a wheel hub (28), (FIG. 1) and a matching non-turning rotor (24) that is slideable linked to a hub (16) that is made apart of an axle support structure (17). The non-turning rotor (24) is controllably coupled with the friction pad disc (18) by means of cam levelr (13), which is a pivotally attached to the axle support structure (17) by an attachment bolt (15). A means is provided for remotely activating the mechanism, which includes a Bowden cable (8), wire (9) and handgrip (10). The friction pad disc (18) provides for efficient brake action and smooth modulation while insulating wheel components from frictional heat associated with braking. The non-turning rotor (24) conducts frictional heat directly into said axle support structure (17), which provides for rapid dissipation of heat by means of air-cooling.
