Last year, I spent I long time riding and testing the top of the line Magura MT8 brakes, and I was highly impressed with them, and found them to be the epitome of German perfection. I was very interested to see how their little brethren, the MT6, stacked up against them, since they share many of the same basic traits and technologies.
The Magura MT6 brake is very lightweight (310 g w/ 160mm rotor) and extremely quiet, with great modulation, excellent power and resistance to heat, drag and squeal, which all combine to make it stand out in terms of performance. They use some amazingly innovative production techniques and materials to create a light and strong brake for any type of riding, from cross-country to downhill, and it transcends being categorized within any riding style.
The brakes use an open hydraulic system, using their Royal Blood mineral oil for hydraulic fluid, with an integrated all carbon reservoir, alloy levers and clamp, one-piece alloy caliper, and full aluminum fitting bolts. They include the trick Storm SL rotors (refer to Storm review), which are available in 140, 160, 180 and 203mm sizes (6 bolt or Centerlock adapter), with a wide assortment of adapters for attachment to any bike and fork.
The reservoir is created by injecting their proprietary Carbotecture material, which is comprised of mid-length carbon fibers in a thermoplastic matrix, into a mold. The fibers are aligned to optimize strength and lightness, in what they call their Carboflow Process, which uses extreme heat and high pressure. The mold work is so precise and exacting, that it requires no post machine processing. The flip-flop designed Carbotecture SL body attaches to the bar with a split handlebar alloy clamp (the MT8 uses a carbon fiber Carbolay clamp). The body uses their EBT or easy bleed technology, set up in a mirror imaged dual-port manner for the flip-flop system, so they can be set on either side of the bars. The alloy lever uses a trick and light hollow-pivot to attach to the body, and rotates on buttery smooth composite bushings.
The forged single-piece aluminum caliper uses a double arch design, just like their forks, and the shape optimizes the caliper’s strength in the direction that encounters the largest load forces, and they also absorb heat, and dissipate it away from the main body. The upper or front fin does the oil transfer between the sides of the caliper, which should provide an additional cooling of the fluid? Their stiffening effect, means that the calipers can be machined further, to remove any unnecessary material for a significant weight saving. The caliper uses top-loading pads, for what they call EPR or easy pad replacement, so the wheel doesn’t need to be removed for changes. The caliper has PM mounts, an adjustable hose fitting, and uses two Duroplastic injection molded composite pistons for less heat transfer to the brake fluid, and the pistons have an embedded magnet for brake pad attachment. The organic pads come in two models, the default 7.1 semi-metallic performance versions for maximum power, or the optional 7.2 endurance version for longevity.
