I have a Kona Dawg Primo. Only upgrades are Crossmax ST Wheels and a PUSHED shock. The stock brakes are the Hayes 9's. I like these brakes, but on long steep downhills I get brake fade to the point where it gets dangerous. The rear brake is also noisy all the time. I weigh 220 and ride very aggresive. I have been looking at the Juicy 7 and the Ultimates, the Hope Tech M4, and the XT 775. Any feedback or other options is appreciated.
