The following data is given for a caliper disk brake, with circular pad, for the lightweight two-wheeler, The following data is given for a caliper disk brake, with circular pad, for the lightweight two-wheeler,
torque capacity = 1500 N-m
number of caliper brakes on the wheel = 3
number of pads on each caliper brake = 2
coefficient of friction = 0.35
average pressure on pad = 2 MPa
The ratio of pad radius to the distance of the pad center from axis of disk is 0.2. Calculate the radius of the pad.
