Claim:
Mechanical brakes with pads adapted to be mounted on bicycles, acting to brake by friction of the pads, characterized in an arch movable in rotation ( 1 , 67 , 93 , 125 , 132 , 144 ) whose axis of movement is parallel to the axis of rotation of the wheel, the arch being activated at an upper and central portion by the action of one of a cable ( 8 , 36 , 71 , 128 , 146 ) and a sleeve ( 35 ) connected to a brake handle ( 32 ), said arch connected at each end disassembleably to a pin ( 9 , 57 , 101 , 115 , 129 , 143 ), said pin receiving a cam finger ( 21 , 63 , 96 , 119 , 135 ) which under the action of the movable arch acts with a movement of rotation against the flanks ( 40 , 41 , 97 , 98 ) of a hollow cam ( 23 , 114 , 141 ) pierced by a hole ( 24 , 99 , 142 , 148 ) provided to receive the pin ( 9 , 57 , 101 , 115 , 129 , 143 ), said hollow cam being V-shaped with a flat angle of the dihedral being about 90, said cam finger controlling by movement of rotation the action of the pads, and a resilient return system ( 26 , 104 , 125 , 132 , 144 ) of the pads.
