SOME BRAKES ARE TOO SENSITIVE ACCORDING TO PERFORMANCE TESTS

AVERAGE DRIVERS CONSISTENTLY STOP IN SHORTER DISTANCES WHEN THEIR CARS REQUIRE SIGNIFICANT BRAKE PEDAL FORCE TO REACH HIGH DECELERATIONS THAN WITH VERY SENSITIVE POWER BRAKES. STRENGTH OF WEAKER FEMALE LIMITS MAXIMUM BRAKE PEDAL FORCE. TWO CARS WITH DIFFERENT GAINS AND PEDAL COMPLIANCES WERE TESTED. RESULTS CONCERNING LOSS OF CONTROL, WHEEL LOCKUPS, DECELERATION, EMERGENCY STOPPING, AND CONTROLLABILITY ARE DESCRIBED. /HSL/
