The invention discloses a measurement method of a disc brake dragging torque. The method comprises the steps of: (a) suspending wheels; (b) pressurizing a brake caliper assembly; (c) pulling the wheels to rotate, and recording the tension; (d) disassembling the brake caliper assembly, rotating the wheels, and recording the tension; and (e) calculating the dragging torque. Through the mode, the invention can provide a dragging torque measurement method in a whole vehicle state. The invention further discloses a heating characteristic evaluation method of a disc brake; The method comprises the steps of: (a) repeatedly accelerating and braking, parking when the temperature of the brake rises to a preset temperature, and suspending the wheels; (b) rotating the wheels when the temperature is lowered to a first measurement temperature, and recording the tension; (c) rotating the wheels when the temperature is lowered to a second measurement temperature, and recording the tension; (d) rotating the wheels when the temperature is lowered to a third measurement temperature, and recording the tension; and (e) drawing a curve of the tension changed along with the temperature. Through the mode, the invention can provide a method for evaluating a brake heating characteristic in a whole vehicle state.
