Hayes Dyno Hydraulic Brakes (2012)

Same as the most brake manufacturers, Hayes takes a step back and launches a new set of hydraulic entry-level disc brakes, Hayes Dyno. Thus, Hayes follows the trend of manufacturers such as Avid (Elixir 1), Tektro (Draco) or Shimano (M446), competing in this segment aimed at users eager for performance on a tight budget.

This is indeed the formula for success, but Hayes didn’t quite make it, neither when it comes to planning nor for real life use. Hayes Dyno brakes have a pleasant look and they seem quite solid but, unfortunately, only till you begin to use them. Lever can be operated with two fingers and provides a good grip. And that’s about it, the low price seals this very short list of positive attributes.

What follows next is astonishment in its pure form, as we’re talking about a proven manufacturer such as Hayes. Braking force leaves a lot to be desired and I could conclude by this statement that Dyno is among the weakest disc brakes I’ve ever tried. A certain level of modulation seems to be present in some degree, but the point of maximum braking performance is achieved somewhere below, when the lever is already too close to the handlebar, and your fingers are in danger of being trapped in a press. This is why I recommend you move the levers inside the handlebar.

Long descents are not at all on Dyno’s taste, as the rotors become very hot. Keep riding and you will soon feel the brakes loosing power. And unfortunately, I don’t think that this weak braking force can be compensated, not even by using larger diameter rotors.

Another minus refers to the lack of adjustment when it comes to lever-handlebar distance. Basically you receive the brakes without any adjustment possibilities, which today is quite rare. One solution would be to introduce more brake fluid in the hose, and thus obtain a higher braking point. However, you must take into account that the brake pads will get very close to rotors, and no rider really wants this.

Weight isn’t small at all, as we’re talking about 514 grams (out of which the V6 rotor takes 114) which you really get to feel, when you install these brakes on the bike. After all, total weight is above 1 kilogram.

At the end of the day, I was gently playing with Hayes Dyno’s lever, staring into space and wondering if, in fact, someone from the factory, anyone, actually tried these brakes after they were made. Or perhaps, they were given this name borrowed from a cartoon character. One might also consider the more expensive Hayes Dyno Comp model which is supposed to offer better performance. However, the standard version of Hayes Dyno hydraulic disc brakes is offered for less than 100 euro/pair. Remarkable price, indeed, but in this case, I’d go for a pair of quality V-Brakes!

Weight: 514 grams
