I was reading the downloaded manual for hayes discs (bought some today...don't have em yet) and in one section it talks about the possibility of long downhills causing the brake fluid to get so hot it boils. I ride fireroads a lot and coming back down some of the steep ones i have to brake very hard and very often. They are up to 8 miles, tho most are around 3 or 4.
Is this something i have to worry about? Has anyone had this happen to you, and when it boils what are the results? I weigh around 170 if that matters.
(these d@mn things are looking like more and more trouble the more i read about them)
