A low speed plate brake tester has been designed to measure brake forces applied to the road simultaneously at all four wheels. The dynamic data is displayed in the form of four force vs. time graph. Computations of dynamic brake balance between the front and rear axles and between individual wheels on each axle are displayed. The objective measurements can be automatically compared to specifications for the purpose of auditing vehicles. The static weight distribution of the vehicle is also measured for the purpose of determining the maximum deceleration achieved by the vehicle during the test.
