You wont get a huge gush.
Best way is to PRESSURTE BLEED THEM, fronts can be done normally, rear can be done by disconnecting abs pump then turning ignition to 1, then pressure bleed.
I use a GUNSONS EEZI BLEED, works great just lower tyre pressure to what it says on bottle, about 20 psi if I rememeber right.
Braided lines do make a nice improvement.
