A Comprehensive Study of Humidity Effects on Friction, Pad Wear, Disc Wear, DTV, Brake Noise and Physical Properties of Pads 2011-01-2371

Passenger car NAO(Non-Asbestos Organic) disc pads were subjected to low and high humidity conditions. Humidity is found to measurably affect pad dimensions, pad hardness, compressibility, friction, pad wear, disc wear, disc roughness, DTV(Disc Thickness Variation) and brake noise. Also the friction film is found to absorb a significant amount of moisture. It is essential to have a tight control of temperature and humidity for brake testing and quality control if meaningful data are to be generated with minimum variability. Seasonal changes must be considered for brake testing on the road.
