Abstract
An anti-lock brake for in-line skates, skateboards, or the like. The brake is adapted to be selectively secured to the wheel frame proximate the rear wheel and comprises a pivoting tongue member engaging the circumference or ground engaging surface of the rear wheel when an integral braking skid pad is caused to firmly engage the ground. A resilient member resiliently inhibits the tongue member for engaging the rear wheel except during a severe braking operation. The skid pad remains the primary braking mechanism, and the tongue provides a second anti-lock braking mechanism. The tongue of the pivoting member has a concave surface closely conforming to the contour of the rear wheel to minimize tire wear, and further insures that wear does not distort the shape of the wheel. A large contact surface is established when the braking tongue engages the wheel to distribute the heat generated therebetween to reduce the chance of the wheel melting.
