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

Detailed Brake Analysis… |

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
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.
Color-coded bar graphs report the results. Green means the vehicle passes, red indicates a problem. |
|
 |
Static Weight Results
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.
All axle weight limits are user programmable to accommodate different vehicle platforms. |

Conclusions
“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. |

Axle-to-Axle Imbalance During braking, the stronger axle will lock up first, resulting in loss of steering control or jack-knifing. Left-to-Right Imbalance Test Parking or Emergency Brakes Dynamic Weight and Deceleration Static Weight Adhesion Utilization Can Test Fully Loaded Vehicles |

 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. (Part # 20-967-1) |
 Results Can Be Printed Automatically 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. |

SS100T Sideslip Tester |
 |
|
60-Second Alignment Check |
||
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 semi-trailers; 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. |
