Stopping Distance Performance TestingTest Description: These results are from a production level brake system test that GM calls the High Energy Brake Fade Test. It involves 10 maximum stops from 60 mph, which are performed in succession. It is a brutal vehicle test that showcases the capability of the entire brake system, testing how it handles the extreme conditions of performance driving without a drastic degradation in performance. In general, the data from the first five stops are not considered in the results analysis, as the main focus of the test parameters and results are the last five stopping distances.Comments: GM Brake System Engineer Jay Laws believes this system makes a dramatic improvement in real-world brake performance. He acknowledges, "This cooling kit will also result in improved rotor longevity and brake-pad wear characteristics-along with improved brake-pedal feel in extreme driving conditions." In general, he believes that you're going to be happy with the results.

YOUR QUESTIONS ANSWERED:
| Time spent working: | 3 hours |
| Mechanical difficulty: | Intermediate |
| Tools needed: | Various ratcheting wrenches, sockets (18mm swivel, 18mm deepwell, 36mm standard, 5mm Allen, 19mm and 13mm), a dead-blow hammer, side cutters, prybar, and an impact wrench. You don't need the impact wrench, but it will definitely make the job less physically demanding. You'll also need a way to lift the vehicle and safely hold it up with the front wheels/tires removed. |
