SRAM Maven Long Brakes Long Term Review: The Power Benchmark

By: Trevor Mejia

Are these still the Most Powerful Mountain Bike Brake? 

There are a handful of parts that change how you ride. Tires, suspension, and brakes are at the top of that list, because they decide how fast you are willing to go and more importantly how much control you have when it gets real on trail. Maven has been that kind of change for me. Not because it magically makes you a better rider, but because it moves the ceiling on power so far up that you get to choose how much you want, instead of constantly hunting for more.

It has been 2 years since Maven was released to the world.  After countless trail rides, shuttle days, racing and enough sustained descending to cook any other brake system, my take is simple: Maven is the strongest brake I have ever run on a mountain bike, as long as the setup is correct. 

What Makes Maven Different

Maven was not a small update to Code. It is a different brake with different pads and fluid. The caliper piston sizes are enormous, and SRAM matched that with a larger lever and a leverage curve designed to keep the brake controllable instead of feeling like a light switch. With most brakes, you pick rotors and pads to find the most power possible. With Maven, you start with more power than you probably need, then you tune for feel and heat management.

SRAM put Maven and now other brakes in their lineup to mineral oil, and that matters more than the internet arguments would suggest. Mineral oil does not absorb moisture like DOT fluid, which helps consistency over time and extends service intervals. The tradeoff is that you need to use Maxima's specific mineral oil, and you need to be careful about keeping DOT tools and fluids far away from anything Maven related. 

Power and Feel on Trail

On trail, Maven’s character is a strong initial build into a deeper, more supportive ramp as you pull farther. With SwingLink on the higher tiers, the leverage changes through the stroke so you can stay precise at light braking forces, then access serious power when you need it. When set up correctly, the lever is solid and confidence inspiring.

Compared to the usual heavy hitters, Maven feels like it has more in reserve. Think of it as the first brake where I stopped thinking about “do I have enough brake” and started thinking “how do I want it to feel today.” That is a subtle but meaningful shift. It lets you brake later, shorten braking zones, and stay looser because you are not death gripping the bar to get the bike slowed down.

Rotor Tuning

I run 180 mm HS2 rotors on my trail bike most of the time. That is not a typo. With most brakes, 180s can be fine until you hit long descents, higher speeds, or heavier bikes, then you start chasing heat and power with bigger rotors. Maven changes the math. On any other bike I would be fiending for a 200mm or larger rotor just to keep them lasting long enough to last more than a few months. 

For bike park days, I will occasionally bump the rear to a 200 mm rotor, mostly for heat capacity and consistency when you are doing repeated high speed stops but have stayed with a 180mm on the front. On a bike like that, I do not see a need to go over 200 mm, something I would not do on any other braking system. I can understand 220 mm on a dedicated downhill bike, or a heavy e bike doing long descents where heat management becomes the entire game, but even then, 220 can feel like overkill with Maven in a way that it simply would not with most other brakes.

The hidden advantage of running smaller rotors with a powerful brake is control. You can keep the system in a happy temperature window and avoid the feeling of a brake that is either sleepy when cold or grabby when hot. Maven gives you enough power that you can size rotors for heat and feel, not just for survival.

Pads and Rotors: Tuning Instead of Compensating

Maven uses a larger pad shape, and pad choice matters a lot here because you are not fighting for power anymore. Organic pads are a great baseline because they are quiet, easy to modulate, have a harder initial bite but they make the brake feel less aggressive over the course of a run.  If you ride in wet conditions, or you want the most sustained bite on long descents, sintered pads are the right choice. The organics come as the stock choice from the factory but I much prefer the feeling of the sintered pad, changing to those before they get bedded in on a fresh rotor

Rotor choice is the other big one. HS2 rotors add power and manage heat better than CenterLine style rotors. That is an easy way to bump output without changing rotor diameter. And if you want a bigger change in power, stepping rotor size up or down is the cleanest adjustment you can make.

One important note that a lot of riders skip: if you change pad compound, do yourself a favor and run fresh rotors or at least dedicated rotors per compound. Mixing compounds on a rotor that is bedded to something else is a fast path to noise and inconsistent bite and feelings. 

The Main Flaw: Big Pistons and Big Inconsistency 

The same thing that makes Maven special is also its biggest weakness. Those massive pistons create a lot of seal surface area, and that can translate to more friction if anything is slightly off. When the pistons are not moving freely, Maven can feel like it has a heavier lever engagement, inconsistent bite point, or a vague “pump it up” feeling that shows up after the bike sits or after a hard descent. It is frankly a huge issue that can be pretty frustrating at times especially as a mechanic that expects 100%. 

This is where the chatter online has been the loudest, and it tracks with what I have seen in the real world: Maven is only as good as the bleed, and the bleed is only as good as the piston movement. People say Maven takes more hand effort or feels harder to engage. In my experience, when everything is right, it is amazing. The lever has a little more resistance in the free stroke, then it becomes extremely easy to access real stopping power once the pads meet the rotor. If the lever feels oddly heavy early, or the bite point wanders, the caliper pistons are almost always the first place I look.

Bleeding Maven: The Brake Is Good Only If the Bleed Is Good

Maven is not difficult to bleed, but it is less forgiving than many brakes because it has so much fluid volume and so much piston area. Trapped air that might be a minor annoyance on another system can become a real performance issue here. The biggest tip is to really follow the prescribed bleed process, then do the piston massage step. 

We made an article and video here: 

Piston Massage: The Secret Sauce for Maven Feel

If you remember one thing from this entire article, make it this: piston massage is not optional on Maven. The goal is to make sure all four pistons advance and retract smoothly, evenly, and with minimal seal stiction. That is what stabilizes lever feel and makes the brake easy to engage.

The method that works consistently:

Use a safe piston stop so the pistons cannot overextend. Two old 2mm rotors stacked to create the right spacing works well, and it gives the pistons a broad surface to press against.

Pump the lever until the pistons extend firmly against the stop. Do a few deliberate, stronger squeezes to help the seals settle and to encourage any stubborn micro bubbles to move.

Then, with a plastic tire lever or a proper piston tool, press the pistons back in slowly and evenly. Go in small increments. If one piston wants to run away, stop and correct it. Don’t go too fast or you will run the risk of a piston popping and the entire system will need a fresh bleed. 

Repeat the extend and reset cycle several times. You are not just moving pistons, you are reducing friction and teaching the system to return predictably.

When you nail this, a lot of the common complaints disappear. The lever engagement becomes consistent, the bite point stays where you set it, and the power becomes easy to access without inconsistent sensations in the brake lever. 

Long Term Durability and Maintenance

Once set up properly, Maven has been impressively stable for me. The mineral oil system is designed around longer service intervals, and it shows in day to day feel. I have had fewer “it felt perfect yesterday, why is it weird today” moments compared to some DOT systems, especially when the bike sits for a while, but this is only when the bleed is perfect. 

Pad life and rotor wear have been normal to slightly better than what I would expect given the power on tap. Because of the offset sized pistons, the leading edge does wear faster than the trailing edge. It is important to replace the pads when they get to their minimum because of this. You can check pad wear and rotor thickness using SRAMs included pad spacer. 

I have seen online about some people complaining of leaking calipers or squeaky levers, but on the Maven Ultimates that I have been testing, they have been pretty good as far as quality and durability is concerned. 

Maven Base vs the Rest: Why the “Simpler” Maven Might Be the Most Consistent Maven

If you look at Maven “Base” on paper, it reads like the budget option. In practice, it makes a strong argument as the reliability pick of the whole Maven lineup, and it comes down to one boring detail that matters more than anodizing or hardware: piston sizing.

The standard Maven caliper (Ultimate, Silver, Bronze) mixes piston diameters (18 and 19.5mm), which is a big part of how SRAM gets that signature ramp and ridiculous top end power. The tradeoff is that the system becomes more sensitive to anything that adds friction in the caliper. When you have huge pistons and two different sizes working together, any small difference in seal drag or piston cleanliness can show up at the lever as heavier initial engagement or a bite point that feels like it moves around. That is why the piston massage step matters so much on these brakes.

Maven Base takes a simpler approach with four equal 18 millimeter pistons. Even piston sizing seems to make the caliper feel more repeatable day to day, because it is easier for all four pistons to advance and retract evenly without one side trying to lead the dance. It does not magically eliminate the need for good bleeding or clean pistons, but it does feel less picky about staying perfectly synchronized. The end result is a brake that can feel more consistent for riders who do not want to chase differences in lever feel.

The compromise is that Base gives up some of the refined features. The higher end Maven levers have a more sophisticated feel and more tuning, especially when you step into Silver and Ultimate with pad contact adjustment, pivot bearings and swinglink lever ratio. They also have a banjo at the caliper on Silver and Ultimate, which helps hose routing and reduces stress at the caliper when your frame or fork wants the line to leave at an awkward angle. Base keeps things simpler, both in lever architecture and in the way the hose interfaces, which is great for consistency but not as premium in hand feel or adjustability.

So if your priority is the cleanest, most tunable lever experience, the higher models still win. But if your priority is getting Maven power with fewer variables and a calmer day to day personality, Base has a real case. Equal pistons, simpler behavior, and a brake that rewards good setup without feeling like it demands constant attention.

Who Maven Is For

If you ride steep trails, higher speeds, bigger bikes, bike park, enduro racing, or an e bike that sees real descending, Maven makes a ton of sense. It is also a great choice for riders who are tired of chasing power and want to tune feel instead.

If you are the kind of rider who never wants to touch a bleed kit and expects perfection from a sloppy initial install, Maven might frustrate you. It is not high maintenance, but it is high consequence if you skip the important steps.

Bottom Line

SRAM Maven has raised the ceiling on braking power in a way that actually changes your setup decisions. With conventional brakes, it is common to constantly be asking more out of your brakes. Mavens flip the script a bit, providing more than adequate braking forces for all types of gravity riding without much stress. 

But Maven is not a brake you can half install and expect to love. The huge pistons are the secret to the power, and they are also the reason the system demands a perfect bleed and free moving pistons. If the bleed is even slightly off, or if piston movement is sticky, the lever can feel heavier than it should and the bite point can wander. Do the bleed carefully, commit to the piston massage, and Maven becomes easy to engage, consistent, and absurdly strong with real control behind it.

If you want the most refined lever feel and tuning range, Silver and Ultimate are the picks. If you want the most consistent, least picky version of Maven power, Base deserves a serious look. Either way, once Maven is set up correctly, it sets the current standard for power and makes most other brakes feel like they are working harder than they need to.
