The German-engineered MT Next series of hydraulic disc brakes evolves into something even better than the original MTs for 2014. The Magura MT4 Next Brakes represent a step-up in hardware compared to the entry-level MT2s, which themselves are already world-class brakes.
To make the Next generation better, the MT was scrutinized top to bottom. Magura's engineers kept materials consistent, including the proprietary, injection-molded CarboTecture master cylinder, because CarboTecture is insanely light, strong, and reliable and finds perfect application here, but the housing and the piston itself were refined to be even lighter, stiffer, and more efficient in movement for greater control and consistency. The master cylinder also retains its radial (perpendicular to the handlebar) configuration, because that affords the best modulation and sensitivity for the lever. The hardware of the lever pivot, however, has been simplified to improve reliability, reduce weight, and it's been moved 20mm closer to the handlebar, increasing leverage for even greater feel and control. Of note is that the MT4 gets an alloy lever upgrade over the MT2's composite levers.
The MT's calipers saw revisions, as well. The 4's two-piston caliper is forged, as opposed to the 2's die-cast construction, making the metal more dense for increased rigidity and responsiveness. Like all the Next calipers, however, its one-piece construction has been both lightened and enlarged to increase stiffness and heat dissipation for still greater control. The brake pads are still top-loaded, too, for easy swapping, and any previous MT brake pads will work with the new calipers, but for the Next series, Magura engineered a new compound that increases friction, reduces noise, and prolongs pad life. As opposed to the MT2 fixed system, the MT4's caliper hose banjo is adjustable, to make it easier to route the brake's hosing, no matter where on the frame the caliper is installed. Finally, the MT's bleed plug has been reinforced to be more difficult to damage in the event of a crash, further ensuring that the Next generation of Magura disc brakes, like all before them, last years beyond the competition.
The Magura MT4 Next Brakes come in a Black/silver color scheme only, and one caliper/lever set weights approximately 345 grams. The calipers are post-mount style, and the brakes do not include rotors.
