We were half way down this nice winding hill (in Cairns NQ so imagine 30+ degree day as it was) when my b/f on his R1 had to pull off to the edge of the road. Said he's brakes had faded away to nothing so he would have to go slow for the rest of the hill. After a break at the bottom to let the bikes cool off he checked his brakes and all was fine again. So we're thinking he just over cooked the brakes. Has anyone incounted this problem before? There was four other bikes there that had no problems. What do you recommend we start looking at? The brake fluid, the pads, the disc or the whole set up in general.
