When I travel down long steep grades, I shift the transmission to a lower gear, so that helps to keep the speed down & I don't have to use the brakes so much. I tow a travel trailer with my Suburban keep it in second gear going down steep mtn roads. When I do steep on the brakes, I step on it a little harder to slow faster & then keep my foot off the brake until I need to slow it more. Be sure you don't ride the brakes.
