I am a tried and true shimano brakeset user but experience wandering bite point issues on the hardest technical runs. A moving bite point on vertical dirt is just unacceptable and unnerving. It is inherent in the design of brakes that do not have a bladder and have to be vented to the atmosphere to account for pad shrinkage. I decided to test some brakes that are sealed systems (like auto brakes). The first ones I tested are these Hayes Dominion A4.

I tested a set of these brakes on a DH bike for a week at Angel Fire, about 100 miles or so. They came through in every way. I am 200lbs and they handled double black trails at Angelfire without sweating. I never felt unsafe on them. These are true DH capable brakes with modulation that leaves them very useable on any trail bike also. You will never feel like they are too powerful or touchy, while being able to lock each tire with one finger if you want to. The modulation is naturally better than the shimano standard binary feel, but don't feel anywhere near as lazy at TRP Quadiems or Sram Guides. I did sample different pads and found that the stock metallic (not sintered) supplied the best power performance, which is the opposite of what Hayes says. I settled on the MTX Gold Ceramic on the front and the stock metal pad on the back. The MTX pads are a nice, noise-free $40 upgrade that come with the used brakes. Being able to lock up the rear is something I don't want that to happen without a deliberate effort, and these provide that modulation. Switchbacks were a breeze with them.

If you have never had a truly powerful brake that actual modulates, they may surprise you. I have used Hope V4's and Quadiems on the same terrain and these are about 40% more powerful than each of them. They deliver much more brake control than shimano, no surprise there. I didn't have even one instance of wandering bite point, or fade. After bedding in, they remained noise free, even in 1/2" of rain.

Brand new set, for $185 ea side.

These are over $500 with tax at most shops.

I-10 and Chandler Blvd
