I'm not absolutely certain, but I have always thought it better to use intermittent, brief heavy braking and non-braking (to let brake shoes/pads cool down) which will then resist fade. Paying attention to traffic and slowing down prior to needing panic braking will also extend pad/shoe life. I think my 1999 GMC Sierra 2500 pickkup is still on its original pads and rotors after 175,000 plus miles.

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.

Use the transmission S on 4-5-6% grades at about 45 MPH. The brakes are used only in short applys to prevent over speeding the engine. On steeper grades you may need 1st. If allready above 35 do a brief firm apply to get the speed down, then go from S to 1. Again use brakes only to prevent engine overspeeding. You can't hold a GMC back on a long grade using brakes alone. Also those high temps are bad for wheel bearing grease and can glaze linings and warp rotating parts. Using higher test fluid just moves the problem to a higher temp, making it worse for lubricants and brake parts.

I was in Yellowstone driving the switchbacks in 2nd, maybe 1st, in my old Class C. All engine braking. Rarely touched the brakes.
There was a long line of cars behind me.
I was feeling pretty guilty.
We came to a 2 lane passing zone and I kept going slow so they could pass. NO ONE passed me !
I felt better about going slow after that.

This has been discussed back in 1980 and the consensus was to not ride the
brake but pull the speed down and let it pick up again.
I know it is hard to do when there are heavy traffic.
