Peer, just a couple of tips on brake use on heavy vehicles with drum brakes
on steep downgrades.
1. Turn off the cruise control.
2. Make efficient use of the brakes by reading the posted downgrade signs.
If it says 6% grades for the next 3 miles, anticipate that you are going to
need some heavy braking. Reduce speed by applying moderate to heavy pedal
pressure before sharp curves and slow the vehicle to the posted curve
speed. If the grade is so steep that the coach constantly gains speed,
downshift into 2nd.
3. This is important ! Do not rest your foot on the brake pedal. This will
constantly heat the brakes and lead to fade. Apply the brakes enough to
slow the coach, then take your foot off the pedal. This will help cool the
brakes between uses.

Do as Ken suggests sure sounds like moisture in the brake fluid to me. Had
it happen to me in Kings canyon no joy when you loose your brakes on a down
grade. Use your trans to slow you down on steep grades or the brakes will
get very hot.
