Sharing the same CarboTecture technology (German for carbon fiber-reinforced thermoplastic) as the flagship cross-country MT8 brake, the Magura MT6 Disc Brake matches the MT8's stopping power for a hair more weight and a lower price. While the MT6 outweighs the race-level MT8, they get the advantage of additional cooling fins -- making them ideal for heavy-duty use like all-mountain or clydesdale applications.The caliper features a double arch design, similar to Magura's fork crowns. This adds stiffness to an otherwise superlight caliper body. A banjo fitting on the MT6's two piston, forged aluminum, post mount caliper makes for clean line routing on current frame designs. To ensure there's no unwanted drag, Magura gives the piston seals a special treatment so they retract under dirty and dusty conditions. The pistons are made of a thermoplastic that insulates the fluid from heat generated by the pads, which helps keep braking consistent during steep descents. Magura continues to use magnets to help hold the steel-backed organic pads in place, but has made pad changes even easier with a top-loading design. This also adds an upper window to further vent heat, enhancing performance and increasing life. If you've ever struggled with installing your wheel due to aligning the rotor into the caliper, you'll appreciate the chamfer Magura adds to help guide the rotor between the pads.The CarboTecture master cylinder is stiffer, lighter, and stronger than comparable parts made of aluminum or magnesium. Magura made both sides identical so you can run your levers traditional or moto without worrying about creating a hassle when it's time to bleed the brakes -- there's a bleed screw on the top and bottom. Magura's Easy Bleed Technology (EBT) means that maintenance is simple and mess-free -- no more opening the reservoir and spilling mineral oil all over your bike and the floor. It should be noted that Magura uses mineral oil because it is non-corrosive and non- toxic.While the MT8 gets carbon fiber levers and clamps, the Magura MT6 sports an ergonomic aluminum lever and alloy clamp. The MT6 weighs in at 234 grams for the lever, caliper, and line -- rotors and adapters are available separately so you can choose the appropriate ones for your application. The MT6 Brakes come with a 5-year, leak-proof warranty, and they're Matchmaker compatible so you can mount your SRAM trigger shifters on the same clamps as your brakes.
Strengths: Modulation, no need for bleeding (so far), light weight, reasonable price
Weaknesses: bed in
Bed in took a while, but after they are bedded in, they work great. I've been riding in 2-10 degree celsius temps and have not had to bleed them. They work great when it's wet and are quiet. Modulation is logical and progressive. Power is good, even with a 140mm rotor on the rear. Easy installation and setup, with videos provided by Magura if you need help.
Strengths: Very logical modulation feel.
Easy to bleed.
Weaknesses: EBT screws are plastic, which makes them very easy to destroy
Needs xtra bleedings when temperature is less than -15C
Overall I am very satisfied with my MT6 brakes. Especially brake power modulation fits for me perfectly. Only downside on my MT6s is constant need to bleed them on colder winter days. System leaks a little when temperature goes under -15C and brakes needs bleeding after 20hr of riding (luckily bleeding is brain dead simple). When temperature rises leakage stops. Beside of small leaking, these brakes have no other issues with coldness.

Strengths: These German engineered and German made brakes have great power and modulation. The rotors are a bit thicker than
most of the rotors out there so they stay true. I have not had any significant fading problems with the mt-6 brakes. These brakes hardly squeal when they get wet. Nice full size levers. The unique caliper piston seals keep the brake pads centered
