A brake apparatus for an automotive vehicle having a wheel hub and a steering knuckle, wherein an annular V groove is formed on one side of a rotary disk of the wheel hub; a V-shaped brake member is mounted on the steering knuckle so as to be removably engageable with the V groove of the wheel hub; and at least one radial bearing and thrust bearing are disposed between a hub body of the wheel hub and an inner circumference of the steering knuckle. The apparatus is smaller in volume and simple in structure without need of a conventional caliper and a pair of pistons and further without producing biased wear on the friction surface thereof.
