Think that 20v NA brakes are pretty good,if they are similar to bravo HGT.I don´t know better brakes than the HGT-when I lightly pressed the pedal,I was thrown against windscreen..
I have on my coupe and HGT Pagid "Blue" pads and AP rotors...I haven´t any problem with this combination -I coupe I could repeat braking from 180-200km/h to 0 in very short time without any problem...
The presumption of good brakes is good condition of every componet of brake system (main cylinder,hoses,pipes,calipers..)
