hydraulic e brake setups?

[concept2]

1. whats d difference between an drift e brake with a reservoir vs the 2 line type?
2. if u attach a 'T' to both rear brake lines while using the ebrake with a reservoir will d pedal feel change?
3. anyone has pics of their install

You'll need a check valve. Consider the fluid travel and return. Maybe a lock off valve with the 't'
