ABSTRACT:
A brake test method measures the brake force per axle of a vehicle by having an operator linearly depress the vehicle brake pedal while the axle's left and right wheels positioned on torque motor driven, constant speed rollers. The roller drive torque magnitude is periodically sampled and the samples are filtered to remove ovality discontinuities, the left and right side filtered samples are then compared to detect the maximum brake force imbalance.
