You should brake at the top of the hill and slow down to a speed where you can change down to the next lowest gear. Anticipation is most important, as you may need to change down again to the next lowest gear. Engine braking helps to prevent overheating the brakes, and also assists vehicle stability on steep hills.
You should change down to a lower gear, 3rd gear or if the grade is very steep 2nd gear.
Shift down in to a lower gear.

When going down a steep grade especially if you are pulling a load.
You should down shift ONE gear so it will keep your speed from increasing too much.. and occationally use the brakes to stick with the speed limit..
It could be air in the brake line, or the brakes getting too hot from too much friction by using the brakes on a steep hill or riding the brakes, or there could be a problem with the master cylinder.
I could be your rotors are need to be reground. Let your brake man check out your brakes.
Downshift to the next lower gear. If it is very steep, go down another gear. Make sure you don't over-rev the engine though.
1 way trailer brakes can get you killed...If you are going down a long steep grade (hill) your car/truck brakes (which are only made to stop your car or truck) will get hot and glaze over and eventually completely fail if your trailer brakes don't work properly.You will probably go over the side of the hill,crash into something and kill yourself and possibly other people.If it don't work,don't tow it.
A 6.5% roadway grade means that for each 100 feet traveled, the road rises or descends 6.5 feet. While that might not sound like much, consider that a road might descend for a mile or more in mountainous areas. In traveling just 1000 feet down such a road, you will descend or rise 65 feet. So the answer is yes, that is a pretty precipitous (or steep) grade. You can easily draw a slope defined in percentages using a grid or a piece of graph paper.
You probably have a warped brake rotor. This can happen when the brakes get over heated, usually when "riding the brakes" while going down a long steep hill. Use a lower gear rather than keep continuous pressure on the brakes. The rotors will have to be replaced.
