I was out riding 2 up on some very steep, rutted, gravel hills. I just had to creep down them. I guess I heated my rear brakes up way to hot and the pedal "went to the floor". That was fun!!! I was trying to use a bunch of front brake and alternate them, but I had to "ride" both brakes most of the time. It was way to steep and rocky to leave the clutch out and the speed was a creep, so there wasn't any air flow either. Was getting dark and couldn't stop and let them cool down. Kind of in way over our heads. LOL! Any suggestions other than ride 1 up or take breaks to let it cool down? We're about 360 pounds total loaded.
