A bike brake clamp to provide safe and effective braking including a first brake arm, a second brake arm, a joint plate, and a pilot plate adapted with spring, central screw, cable screw, and pivot screw; both brake arms providing synchronous clamping via the pilot plate to correct the application of brake force on single side of the rim; a moment (longer than that of the prior art) between an adjustment screw at the point where brake force is applied and the central screw at the support being used to achieve better mechanical benefits.
