A return spring storage recess is formed around the support shaft and in the bossed section of the aforementioned brake arm, within said recess is stored the return spring fitted onto the support shaft; while one end of the return spring is engaged onto the bossed section of each arm, the other end is engaged onto the spring cap which is directly or indirectly connected to the support shaft; and a rotating tool seat is provided at the periphery of the spring cap at least on one arm for the purpose of spring tension adjustment.
