First, I think you made a good decision. Hydraulic disc brakes are the way to go, and the M355 are really nice for the price. Also, I assume brake pads/discs are not contaminated and caliper is straight in relation to the disc. These are indeed the cheapest brakes, and therefore there is not much place for adjustments. If without touching the lever the pads ...

Regarding Q2 -- I think both brakes should feel like your front brake -- when the pads contact the rotor, the lever feel should change instantly. If this is not the case for the rear brake, I assume it is due to (tiny) air bubbles somewhere in the rear brake system. It is strange that in spite of this, you observe that the front provides less braking power ...

All brakes work by converting kinetic energy into heat through friction. In disk brakes, the heat builds up in both the rotors and calipers. Under heavy sustained braking, such as down a long steep hill, the calipers can get hot enough to start to boil the brake fluid. Because gases are easily compressible, boiling brake fluid causes a loss of braking ...
