StopTech's second Link 3900 dyno entered service in February 2010 and has been used primarily for full-size truck testing, including drum brakes and armored vehicles, and for parking brake testing. Dyno #2 has also been configured to reach a maximum air velocity of 210mph and can simulate GVWs of up to 24,000 pounds. A third dyno is expected to arrive in 2012.
StopTech has a full library of dyno testing protocols available including SAE J2521 NVH, SAE J2522 Friction Characterization, high load tests and thermal crack resistance tests.
In addition to in-house testing capabilities, StopTech can perform extensive on-vehicle testing. On-vehicle FMVSS 135 testing is performed using the Link 3801 Data Acquisition System. StopTech also employs the VBOX 20SL3 GPS Datalogger featuring simultaneous 3-axis measuring. Setup and changeovers are fast, ideal in racing situations.
Finally, StopTech enlists the services of independent testing laboratories for special procedures such as salt spray testing per ASTM B117, cyclic corrosion testing per SAE J2334, brake hose testing per FMVSS 106 and vibration testing.
