Review on SHIMANO Deore BR-M6120 Disc Brake: Premium Performance and Unmatched Precision by John Love

I love these brakes. Put them on my e-bike. It came with a Shimano MT-200 (I think that's the model number). But 4-piston brakes are good, they act like two sets of brakes in one. Pull the lever a little and they pull the rotor until you pull the lever harder then they stop you in a jiffy, they're two stage. Top quality, just what they should have put on my e-bike to start with as it's a lot heavier. Worth every penny for both front and rear brakes. (Upgrade for $300). Not bad.
