You should bench bleed the new master cylinder before bleeding the rest of the system. Bench beeding can be done before you install the mew m/c on the car. That's why they call it "bench" bleeding

I just installed C5 brakes and a DRM bias spring & didn't know if using a vacuum brake bleeding kit at the calipers eliminated the need to bench bleed the master cylinder. Guess I'll still do it.
