I’ll explain (but if you don’t feel the need to get into the nitty gritty, keep scrolling). The A4’s total lever stroke is, if anything, slightly on the shorter side for a big, four-piston DH brake. … 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. Price. 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. ‘Crosshair’ … Designed with a specific lever pull curve to balance on-demand pressure modulation, providing firm engagement between the pads and rotors… 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. 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. The lever feel of the Dominion A4 brakes is exceptionally light in the early stroke and ramps up quickly and firmly upon reaching the bite point. 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. w/ 20mm Axle, 8" rotor. Where the lever feel of the Dominion A4 really differs from Shimano Saints (and Shimano brakes in general) is in terms of consistency. The Dominion family features three models: The A2, A4 (tested), and the recently released T2. 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 Dominion A4 does feature a tool-free reach adjuster. But we were able to cobble it together well enough with a Voile strap to be useable, and Jed has a documented history of finding creative ways to break things (skip to 13:24 for the relevant bit), so I’m not inclined to hold this one against the brakes. We use cookies to ensure that we give you the best experience on our website. Hint for breaking-in: New disc brake pads require a … 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. … Jed has a documented history of finding creative ways to break things, 5-Ski Quivers: Reviewers’ Selections (20/21), Front, uncut hose: 291 g (no adapter or rotor), Rear, uncut hose: 326 g (no adapter or rotor). Clarks Sintered MTB Disc Brake Pads $7.99 ... Hayes Hayes Dominion A4 Disk Brake. They’re a bit heavy and probably overkill for lighter Trail duty (Hayes offers the Dominion A2 and T2 for that role).

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. The Hayes Dominion is another option in a sea of great four-piston brakes like the Magura MT, Formula Cura4, Shimano Zee/Saint/XTR/XT, and SRAM Code. It’s spent several years data-logging braking habits and then developing … 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 Dominion isn’t just an excellent brake from Hayes, in my opinion, it’s now one of the best trail/enduro brakes on the market – regardless of brand.

The Dominion four-piston hydraulic disc brake has been developed for the rigors of DH and enduro riding provide. Speaking of the lever blade, Hayes goes so far as to offer two versions of it — the “Standard” version, and an “SFL” or “Small Finger Lever” version, meant for riders with smaller hands who run their levers closer to the bar. The rotors are 1.95mm thick and were designed specifically to cancel out any … To save you buying stuff you don’t need, it’s also available without rotors and adapters. It’s a simple system that works well, and makes fine-tuning the caliper alignment much easier. 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 Dominion A4 caliper is a mostly conventional design: two-pieces, four-pistons, and with a pivoting banjo fitting for the brake line to allow for adjustment of the hose routing. Hayes Performance Systems manufactures the highest quality brakes, suspension systems, wheels and components for all mountain bikes, including enduro, downhill, cross country and dirt jumping bikes. 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. The A2 and A4 share the same lever but have different calipers, with two and four pistons, respectively. Finding my ideal DH brake seems like a never ending quest and I always thought I wanted an adjustable bite point to my brakes. 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. The D-Series rotors are 1.95 mm thick and are available in 160, 180, and 203 mm diameters with six-bolt mounting. Having dominated the disc brake market in the late 2000s with the HFX, Hayes has been in the wilderness for a while.

The Dominions do, technically, feature a contact-point adjuster, but it’s not meant to be changed by the user. And tool-free adjusters tend to be bulkier, heavier, and more exposed to being damaged in a crash, but the Dominion’s version is quite neatly integrated into the lever blade. 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. 1 review for Hayes Dominion A4 disc brake black/bronze with an rating of 5 points. not being squeezed). At £44.99 the standard D-Series steel rotor … The Dominion A4 brakes can be ordered with either lever blade installed, and both are also available aftermarket if you’re inclined to experiment (or just happen to break one).

The A2 brakes are intended for XC and Trail bikes, with the bigger A4 brakes meant for use on Enduro and Downhill bikes. I was recently on a ride with K2 / Line Skis designer Jed Yeiser, where he crashed and broke one of his own Dominion A4 levers at the clamp. 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. I’ve been testing their four-piston Dominion A4, a brake intended for Enduro and Downhill bikes, and it is outstanding. The Hayes Dominion A4 goes for $230 per wheel without rotor or adaptor. Clark's. Aftermarket versions of the Dominion A4 brakes come with two sets of brake pads, in sintered metallic (Hayes calls these “T100”) and semi-metallic (“T106”) versions. The calipers and levers got some massive overhauls, but Hayes also developed an entirely new rotor around the new brakes. 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. But for my preferences, they’re fantastic. Dominion A4 features the proprietary QuickBite² system for fast and consistent burnish, coupled with Hayes’ D-Series rotor to manage the heat with less braking noise. At the lever end, the Dominion A4 brakes that I’ve been testing feature a symmetric lever body (no need to swap hoses depending on your preferred brake orientation); a tool-free reach adjuster; and a split clamp with options for SRAM Matchmaker and Shimano I-Spec II compatible mounts, in addition to a conventional standalone clamp (tested). With an extremely light lever-action and immense stopping power, the Hayes Dominion A4 are a great choice for aggressive enduro and downhill riding. Rather, it allows the factory to fine-tune the position of the seal to set it as close to the timing port as possible, to compensate for manufacturing tolerances and so on. 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.

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. I tend to prefer metallic pads to organic and semi-metallic versions since metallic pads generally offer more power and better wet-weather performance, at the expense of a bit of noise and sometimes a little less modulation. 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 Hayes bleed kit is really nice. The SFL is thinner, shorter, and shaped to be run closer to the bar. But if you absolutely insist on backing it off, there is a small screw hidden behind the lever blade to fiddle with. Preferences on lever feel are undeniably subjective, and riders who have found themselves getting along better with brakes with a less abrupt bite point might not be best served by the Dominion A4. To Hayes, the Dominion is a pull-the-goalie fight … 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. 02-22-2020 #4 Phoenix864 But for longer-travel bikes and / or bigger riders that need serious braking power in a reliable package, the Dominion A4 is excellent. 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. 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. Joining the master cylinder to … The lever pivots on a pair of sealed cartridge bearings and has remained smooth and free of play in my time with the brakes. But I've heard that the A4 caliper is a strange shape that requires their own Hayes caliper adapters.

But they’ve inevitably developed issues with the bite point wandering at random after a period of hard use. But the Dominion A4 is definitely easier to modulate than Saints, especially when using the A4’s semi-metallic T106 pads. 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. Hayes Dominion A4 is brake with tons of power and modulation. Hayes absolutely dominated the disc brake market at one time but lost that lead in a big way. The British-made Hope Tech 3 MSRP is just $20 more than that of the Dominions. Put simply, the Hayes Dominion A4 brakes are my current benchmark for a burly, four-piston Enduro / Downhill brake. I tested the A4 brakes with the standard lever and it is substantial, with a fairly large, flat, dimpled face and a deep hook that a single finger nestles into securely. I have the A4 and love them. 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. 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. The Dominion’s master cylinder is factory tuned for the shortest dead stroke possible and a … I wouldn’t mind if the lever blade was a little slimmer, with less of a broad, flat contact surface, but it’s a minor gripe and didn’t give me any real trouble.

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.

To go with the Dominion brakes, Hayes released a revised rotor design, which they call D-Series. The Dominion family of brakes all use DOT 5.1 fluid and feature newly revised, Kevlar-wrapped hoses that Hayes says are stiffer than before, reducing sponginess in the brakes by reducing their expansion under pressure. Compared to Shimano Saints, the top-end power of the Dominion A4 is a touch less strong, but only just. Caliper construction on the Hayes Dominion A4 utilizes a two piece aluminum body and four pistons to grip onto their D-Series Rotor. 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. Going in for a quick stab of brake and having it go to the bar is, to put it mildly, disconcerting, and I’ve given up on running Shimano brakes on my personal bikes for that reason. 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 Dominion A4, on the other hand, has been absolutely dead consistent in my time with them so far. New.

Only once the timing port is closed does the brake start to move fluid through the hose to the caliper, and build pressure to provide braking force. 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… What that means is that contact-point adjusters create a section of the stroke where the brake doesn’t do anything. A4 works great but I do have some wandering bite point – may air in the system? Features 4-piston brake designed for trail, enduro and DH use.
