In the present paper, air pressure and temperature on the interface of the polymer matrix composite (PMC) brake pads are measured by disc brake under braking condition, and their influences are studied as well. The experimental results show that the air temperature peak is not as high as that on the surface. The air pressure of the interface varies with the applied load. The air pressure is negative under the small applied load, but positive under the large applied load. The analysis of the experimental results shows that the phenomena are caused by the friction heat and the rotate disc. Since the air pressure is very small comparing with applied load, it influences on the friction coefficient slightly. But, the negative air pressure of the interface increases the chance of the drag friction in the non-braking mode for disc brakes.
