Now that I have almost a year experience with these Shimano M8000 brakes, this is my up to date assessment. My initial positive report has changed. I would no longer recommend them for our bikes. Although they have strong stopping power, they fade badly after only one or two hard stops. They work well enough for typical city cruising, but they're not at all up to the task of even slightly fast riding. Even one hard stop on a downhill grade makes them fade badly. They also have a small pad area that wears out quickly. They would be great for a regular bicycle, but not a 100 plus lb 50 mph bike.
Besides this major shortcoming I like everything else about them. I love the easy to adjust levers, and they look good on the bike. The pads are easy to change, and they're easy to bleed. I can probably live with the rear brake, but I'm going to look for a better Shimano front brake.

Well, those are two pistons brakes so no wonder they fade. You need to go with four pistons.
So look for Shimano XT BR-M8020

Or
Magura MT5

Or
Best of the best:
Hope Tech V4, they have them in any color

And if you want better cooling go for:
Hope Tech 3 V4 Vented Floating Disc Rotor
Personally I own and use both Hopes and Magura. A like them both where magura are cheap and works good, but Hopes are truly THE gems and have the best premium feel. CNC made from a solid block of ALU, just can not be compared with the stamped alu Shimanos or plastic Maguras. They are a dream to bleed, just as any motorbike or a car out there and they use cheap DOT unlike other ones that need expensive mineral oil. Oh and that name alone, HOPE... Yeah they are the only hope.
