The A2 brakes are intended for XC and Trail bikes, with the bigger A4 brakes meant for use on Enduro and Downhill bikes. The Dominion A4 master cylinder is factory tuned for … They’d quickly settle back in and resume normal performance, and despite that slight downside, I generally prefer the T100 pads for their overall improved power.

Until the timing port is closed off, all that squeezing of the lever does is push fluid back into the reservoir in the lever, rather than down the line and to the caliper, since it follows the path of least resistance.

That said, it has a couple of unique features designed with serviceability in mind. Durability has been good on other fronts as well. It’s a great idea, and, of course, you don’t necessarily need to use both — you can always do a more standard bleed procedure through one of the ports, but the other one is there if you need it. If there was a realistic way to make one that varied the amount of piston rollback at the caliper, that would be sweet, but it’s going to take someone more clever than me to figure out how to actually make that happen. Historically I've been a cheap syringe and piece of tubing attached to whatever fitting I need kind of guy, but between Formula and Hayes… Whenever brakes had lacked this adjustment, I found that fiddling with lever reach sort of helped but at the expense of lever position, especially on long descents when things really heat up and expand.

I’m currently running Code RSCs which I am honestly really happy with and it has a pad contact adjustment which feels like it is doing what I want, but the above discussion about bite point kinda has me second guessing everything I thought I knew about the universe up till now. The A2 and A4 share the same lever but have different calipers, with two and four pistons, … And apart from a quick lever-end bleed when I trimmed the hoses upon installation, all I’ve had to do to them is swap pads as they’ve worn out.

Modern hydraulic disc brakes for bikes operate on a semi-open system, meaning that the lever features a reservoir of “extra” hydraulic fluid that’s connected to the brake line when the lever isn’t being squeezed. Though the A4’s bite point hits hard in terms of lever feel, the power doesn’t come on in such a binary on / off manner. The Dominion’s master cylinder is factory tuned for the shortest dead stroke possible and a … This held true for the Dominion pads as well, though the semi-metallic T106 pads do have better than average wet-weather performance for a semi-metallic offering, and greatly exceed most organic pads on that front. It would require a major overhaul of how the caliper works, since in typical brakes the geometry and material properties of the piston seals are what control the rollback. To go with the Dominion brakes, Hayes released a revised rotor design, which they call D-Series. There’s notably not a contact-point adjustment (at least not a typical one), since Hayes argues that they’re a bad idea, and I couldn’t agree more. And since a contact-point adjuster can only make the total lever stroke longer than the “default” position, all they can do is push the starting point of the lever farther out from the bar, at a given final bite point.

I tend to prefer a simple screw for reach adjustment, since reach tends to be pretty set-and-forget as long as your brakes are working properly. I don’t think I’ve hit the levers massively hard in my time with them, but I have crashed with them a number of times, and apart from some minor cosmetic scuffing, they’re no worse for the wear. But I’ve found the dropoff to be well within the normal range, and they’ve been quick and easy to get up to temperature, even in fairly cool ambient temperatures, with a 203 mm front / 180 mm rear rotor combo. The Hayes Dominions are absolutely excellent brakes. Extremely sensitive modulation doesn’t tend to be at the top of my list of priorities when it comes to brakes — I’m far more likely to find a brake lacking in terms of outright power than modulation.

The new T2 is essentially an A2 on a diet — the T2 gets titanium hardware, a carbon-fiber lever blade, aluminum-backed pads, a bit of extra machining on the caliper, and it loses the tool-free reach adjustment. Of course, they can’t move the seal past the timing port, or the brakes wouldn’t operate properly — they can only open up a gap between the two. I’ll explain (but if you don’t feel the need to get into the nitty gritty, keep scrolling). On a few occasions, when I’d been riding an extended, steep descent and gotten the brakes quite hot, if I took a short break but resumed riding before the brakes had a chance to properly cool down, they’d make a lot of noise and offered significantly reduced performance the first time I really got on them hard after resuming riding, which I’d attribute to them glazing over slightly.

As has been noted widely (by myself and others) for years, Shimano has really struggled to get their brakes to maintain a consistent bite point. As with most metallic pads, the T100 sintered pads do work best when they’re warmed up a little bit — braking power does suffer when they’re truly cold. This allows them, in part, to compensate for things like pad wear and thermal expansion of the brake fluid, as well as having a greater volume of brake fluid available to better transfer heat out of the system. The Dominion A4 uses a proprietary pad shape with an exceptionally large surface area — they’re notably bigger than even Shimano Saint or SRAM Code pads, and they should theoretically help with heat management. To Hayes, the Dominion is a pull-the-goalie fight … Exceptional modulation throughout lever stroke, Modulation gives great control over brakes, Burly construction means no brake damage worries if you crash, Stiffer brake hose and thicker rotors make sense for gravity orientated application, Crosshair screws on caliper make centering easier, Lever modulation lacks consistency during extended descents, Had to reset pistons and/or bleed system to address above issue.

Hayes argues, and I agree (for the reasons stated in the previous paragraph), that there’s no good reason to move it from there. >>> The best mountain bike disc brakes. But they’ve inevitably developed issues with the bite point wandering at random after a period of hard use. And while the lever feel between the two is fairly similar in terms of a light initial stroke (the Dominion A4’s is even lighter) with a quick transition into a firm bite point, the power delivery of the Dominion A4s is notably more linear. DH-oriented brakes often have slightly longer strokes than lighter-duty brakes, due to the higher leverage ratio required to get more power from the brakes. The A4 caliper also features what Hayes calls “Crosshair Caliper Adjustment,” which is, in essence, a pair of set screws on the brake-mount tabs that push against the brake mounting bolts and make it easier to fine-tune the caliper alignment. Hayes was one of the first brands to offer a hydraulic disc brake for mountain bikes, and their HFX-9 and HFX-Mag brakes were everywhere in the early 2000s.

Now that I’ve spent significant time on the Dominion A4, I think it’s safe to say that this is the brake that Hayes needed had to produce. First, unlike most brakes, which have a single bleed port at the caliper, the Dominion A4 brakes have two (one on each side), which Hayes refers to as “2-Stroke.” The idea is that the second port makes it easier to get every last air bubble out of the caliper, since the small passages between the two halves of a caliper can trap bubbles, and having a bleed port on each side makes it easier to draw them out. Hayes says their geometry has been carefully designed to mitigate noise and vibration, and apart from the brief bursts of noise when resuming riding on hot brakes described above, they’ve been fairly quiet overall, including when wet. The A4 Dominions have always sounded great though (the crosshair alignment thing is pure genius), but living in Euroland I haven’t seen these brakes in the wild yet…, I definitely get the appeal of a contact point adjuster in theory, I just don’t think that their promise is borne out very well in practice.
