My first day on a dh bike that I owned the rear brake failed on the lift. Fine in the lot, absolutely nothing and immediately to the bar. I honestly didn’t think about riding the lift back down so I ride the first lap like that. And the second. Finished the day like that. Sunday River in Maine so it was all tech, mostly damp and tons of rocks and roots. As a bigger dude, dragging the rear doesn’t really do much so I usually go through 4 sets of front pads per every 3 rears.
