learned this lesson comming down the blue ridge mountain in VA. side road, damp and way steep. i needed all the brake i had at the bottom to make the right onto 22. 17k gross, upgraded pads on the truck. next time i will be checking up sooner instead of letting it run down the grade.Now for going down. Still in T/H, in drive. Snub the brakes as the speed increases. It will down shift and start retarding. If still too fast /gaining speed, snub the brakes hard twice again. If under 3500 RPM it should step down another gear, and retard harder. The retarding/grade brake is unbelievable when the RPM is over 4000 RPM.
THE IDEA IS TO HAVE COLD BRAKES WHEN YOU HIT THE BOTTOM. Drive it more like a semi driver drives his unit. It will be more fun in the long run. You don't have to win the race.... just arrive alive.
turnpike- do you have a turbine brake working on your truck? been thinking of changing my tune up just to get one. some of these grades headed down south or way up north in NY put the old truck to work.
