Brake and Sideslip Testers for Heavy-Duty Vehicles
B400T Brake Tester
Measures Brake Balance on Multi-Axle
Vehicles in 60 Seconds or Less!
The Hunter B400T utilizes PC-based technology to measure
braking forces for every brake on multi-axle vehicles such as
tandem-axle tractors, tractors and semi-trailers, and two-axle
vehicles, including passenger cars, buses and light trucks.
Drive On and Stop
Drive the vehicle onto plates and apply the brakes. Precision
load cells automatically measure braking forces and dynamic
weight. As each axle is tested, results are displayed on the color
monitor. Results are automatically stored and can be printed out
at the end of the test . . . all in 60 seconds or less!
Measures Weight Shift During Braking
The B400T takes into account the rear-to-front weight shift that
occurs during braking, resulting in a more accurate evaluation
of brake system condition and emergency stopping ability than
roller-type testers.
Detailed Brake
Brake Balance Results
Segments inside each wheel graphic indicate
braking force as a percent of weight: the more
segments, the higher brake strength. For an “ideal”
vehicle, all segments would be the same length.
It’s easy to see which brakes are doing their job.
Segments are color-coded green for pass, red
for fail.
Arrows on each axle indicate side-to-side balance,
with the green area indicating pull. Arrows below
the wheels show adhesion utilization, (a measure of
braking effectiveness) and are also color-coded for
pass or fail.

Service Brake Results
Static Weight Results
This display provides raw brake force data. Linear
graphs plot braking force and dynamic weight. The top
graph shows the steer axle and the bottom graph
displays drive axle or tandem. Deceleration and/or
braking distance can also be displayed, which is
particularly useful for transit applications.
Static weighing is performed automatically as soon
as the vehicle comes to rest. The display shows
static weight for each wheel, total for each axle and
total for vehicle, along with GAWR and GVWR. If
an axle is overweight, the accompanying arrow will
turn red.
Color-coded bar graphs report the results. Green
means the vehicle passes, red indicates a problem.
All axle weight limits are user programmable to
accommodate different vehicle platforms.

60-Second Alignment Check
“Plain English” description of vehicle results are
color-coded and may be printed.
Green “Passed” message is used for test results
that are OK. Red or yellow coded messages are
more detailed and indicate a potential problem
or trouble spot.
nge of Vehicles
The Hunter SS100T measures sideslip, or tire scuff, on
heavy-duty vehicles. Sideslip indicates incorrect toe
settings on steer axles and excessive tandem scrub angles
on tandem or multi-axle vehicles. Sideslip can also be
caused by other mechanical problems.
The system tests tandem-axle tractors; tractors and semitrailers; tractor, semi-, full-trailer combinations; multi-axle
vehicles; buses; and two-axle vehicles including
passenger cars. Vehicles with up to 5 axles can be
measured in a single test sequence.
Green indicates passable results. Yellow (marginal) and
red (fail) results indicate the alignment should be checked.
The SS100T can easily be integrated into the B400T
Heavy-Duty Brake Tester.
Hunter B400T Identifies Conditions
Affecting Brake System Performance
3 Axle-to-Axle Imbalance
During braking, the stronger axle will lock up first,
resulting in loss of steering control or jack-knifing.
3 Left-to-Right Imbalance
Can cause “pulling” to the stronger side during braking,
resulting in a skid. Also detects single weak brakes.
3 Test Parking or Emergency Brakes
The B400T can test mechanical brakes on a straight
truck and spring brakes on an air brake system.
3 Dynamic Weight and Deceleration
Load cells measure dynamic weight of the axles during
braking, and the system calculates vehicle deceleration.
3 Static Weight
Works as a scale, with accuracy of +/- 2 percent.
3 Adhesion Utilization
Tells the technician if each brake is doing its fair share
of the braking.
3 Can Test Fully Loaded Vehicles
WI132 shown
(console must be purchased separately)
Single-, tandem- or triple-axle weight can be tested with
a full load.
Utilizes State-of-the-Art Technology
Console houses a powerful PC-based computer, providing instant test results.
Results are displayed on the console’s 19” LCD color monitor.
Premium color printer is standard equipment, mounts in console.
Sensor microprocessors digitally transfer information to and from the computer. Sensors have no moving parts,
ensuring reliability.
5. Measurement system is recessed into the shop floor to prevent distortion under the weight of heavy vehicles.
6. Heavy-duty steel grating provides traction for proper testing, even when tires are slippery from inclement weather.
Optional Signal
Light helps the
operator stop
correctly every
time. Green light
means tester is
ready; light then
goes from yellow to
red indicating it is
time to stop.

Results Can Be Printed
Printouts serve as a guide for the
technicians performing service
and provide a permanent record
of vehicle status. Results from
each vehicle can be stored on
disk for computer-based record
systems to build an overall
picture of fleet brake conditions.
