Hunter's B400T Heavy-Duty Brake Tester Performs a Complete Brake Performance Test on Multi-Axle Vehicles in Sixty Seconds or Less

The B400T utilizes a PC-based system with Hunter's exclusive WinSI Software to measure brake forces and vehicle weight at each wheel on multi-axle vehicles such as tractors and semi-trailers, tandem-axle tractors, buses and two-axle vehicles, including passenger cars and light trucks. Single-, tandem- and triple-axle vehicles can be tested with full loads.

To perform the test, a technician simply drives the vehicle onto the tester plates and applies the brakes. The precision load cells within the plates automatically measure a variety of brake performance conditions, which are then digitally transferred to the computer, analyzed and displayed on the monitor in color-coded charts.

The B400T identifies many conditions that affect brake performance:

Axle-to-Axle Imbalance – a test of unequal brake performance, comparing axles to determine if one would lock up first causing a loss of steering control or jackknife.

Left-to-Right Imbalance – a test of unequal brake performance, comparing each side of the vehicle to find a pull and potential to skid.

Static Weight, Dynamic Weight and Weight Shift - a measurement of weight of the vehicle and load at a stop, weight of the vehicle and load when braking, and rear-to-front weight shift when braking.

Rollover Propensity – a measurement of the vehicle's center of gravity and potential of rollover.

Parking or Emergency Brake – a test for both mechanical brakes on straight trucks and spring brakes on air-brake systems.

Hunter Engineering is a world leader in wheel alignment, brake service, wheel service and safety inspection lane equipment. Hunter equipment is approved and used by vehicle manufacturers, automobile and truck dealers, tire dealers and automotive service facilities around the world.
