A braking system for an in-line skate, where a linkage assembly connects a rotatable boot cuff to a brake assembly which pivots between a retracted position braking position. The linkage assembly includes a drive arm, a transfer bracket and a short connector link. The transfer bracket has three pivot points which are arranged such that the mechanical advantage provided by the transfer bracket in translating downward movement of the drive arm to downward movement of the connector link and brake assembly is less than one in the retracted position, and increases as the cuff is rotated rearwardly to move the drive arm downwardly and the brake assembly towards the ground. Preferably, the connector link rotates over center to a locked position once the brake is in contact with the ground and the cuff is rotated slightly rearwardly. The distance between the cuff and the brake assembly is adjustable so that the desired adjustment of the linkage assembly and braking system can be maintained as the brake pad wears down.
