new pads/rotors all around, new lines at the wheels. pedal feels great 90 percent of the time, after long hard stops the pedal starts to go mushy and requires a lot of travel and force to stop. it is then soft for a while and then it gets firm immediately and works like it did before, im stumped at this point. gonna try gravity bleeding everything again and when the snow comes, ill try making heavy use of the abs and seeing if theres air in that.
