Theirs is nothing wrong with my brakes they work fine. All I am trying to say is if you use only your brakes and not your gears to slow down in a short time like 2 minuets your back brakes might go flat and not work

 

That's why they put that linkage on the other side of the brake pedal it's called the shift linkage as in shift down. Just sayin'

 

In your first post you said the pedal went all the way down. Correct? They may fade but the pedal shouldn't go to the stop.
Bleed your brakes and the pedal won't do that coming down from high altitudes.
It doesn't take much air in your lines.
Trust me. I ride those passes regularly.

 

just drag your feet when your brakes fail. Or just use tranny in first place.

 

If they are hot they will! Ask me how I know.

 

is this road gravel? If not why are you relying on the rear brakes?

 

Holy **** is this dude takin one for the team here.... damn. LOL.
Takes one on the chin for spealling.

 

Never had that issue here in Florida

Seriously, as a few other have commented, change the brake fluid to a better quality (higher temp point) fluid.

Based on this I will look into using Motul instead of the HD fluid...

 

i had that happen once..going down a steep hill on a 69 sportster chopper. only had a banana caliper on the rear wheel.half way down i had nothing.i rode thru a red light and 4 lanes of traffic at the bottom 40-50mph dragging my feet the whole way

 

I have never had that problem before. And I have gone down many passes. It only took about 1 to 2 minuets to cool down then they were working great. The only thing is it turn my rotor brown from the heat, I check the rotor to see if it was warp and it look ok. The whole thing is weird I still do not know why the brake pedal went all the way down to the stop
