A bicycle brake assembly comprises a main frame, a retaining ring, a rotor and a pair of pintles. A hollow shaft is on the main frame. The first, second and third lugs are on the main frame. Each lug has a hole. The hollow shaft is inserted in the center hole of the hollow rotor. Two recesses are formed on the rotor to receive the heads of the front and rear brake lines. The rotor has two chambers defined by the flanges at the opposite sides of the rotor. The first and second pintles are disposed on the corresponding chambers, respectively. Each pintle has a slot and a circular hole at each end of the pintle, respectively. The bottom circular hole receives a hollow cylinder post. A hollow screw which has a through hole passes through the bottom slot and the hollow cylinder post. One end of the first or second brake control line is positioned by the positioning hole of the screw bolt. The screw bolt passes through a washer, a nut, and the through hole.
