Hayes Hydraulic Disk Brakes
It has come to the point that there are many good working disk brake systems on the market, when only a couple of years ago there were almost none. One of the first disk brake setups to be widely accepted was the Hayes hydraulic system.
Hayes has been making automotive brake systems for many years, most notably for Harley Davidson motorcycles. With this expertise behind them, they produced a powerful, reliable, reasonably light weight hydraulic brake system for mountain bikes, and it remains one of the most popular systems available today.
I have owned two sets of Hayes hydraulics, in both 6" rotor and 8" rotor (photo at top of page) configurations. I find them the best of the current crop of brake systems for several reasons. First is their combination of power and modulation. I have found some disk brake setups to be overly touchy, such as some earlier Hope models. The Hayes have a good amount of power, but also good lever "feel" that allows you to apply as little or as much braking power as is needed. Second is their short break-in period. They tend to break-in well before the end of their first ride, while others, such as Shimano, take two to three rides (or more!) to come to full power. Finally, they have been virtually maintenance free, and parts are readily available if needed. Some systems, such as Hope, can be hard to find parts for.
Judging by the number of Hayes systems I see on riders' bikes these days, and by the number of manufacturers who spec them OE, I am not the only one who prefers Hayes...
Update August 5/03
The brakes on the '03 Stinky are the less expensive Hayes hydraulics. They work fine, except that if the levers are ever forcibly pulled away from the handlebar, there is a small circlip on the inside of the lever that can easily pop out. If this happens, it is possible to lose a bit of fluid, and the brakes generally will not work properly. There is a warranty fix consisting of a new circlip that can be done if the lever pops out, and if fluid is lost they will have to be bled. Otherwise, it is business as usual for these brakes.
