+1 on flushing the system.

Getting all the air out of an empty hydrallic system is a pain.

I use a big 500cc plastic syringe (buy from any pharmacy) and suck almost all the fluid out of the reservoir. Refill the syringe from a new bottle and PUSH that new fluid from the bottom bleeder bolt UP towards the pump and reservoir.

That way you aren´t working against the air, since it wants to rise to the top anyhow. Works in 2 minutes on my front brakes and clutch. Rear is abit more difficult, but the same principle.

I had to take the rubber tubing of my "old" bleeder and attach it to the syringe to make an airtight seal between the bleederbolt and the syringe.

The syringe is purged of air in the same way that doctors do (top up and klicking it with your nail)

Since the bleederbolt is facing UP, i put the syringe on there (with the rubbertubing to conect the syringe to the bolt) and wait a while so that any air that has come in rises to the top of the syringe (Where the plunger is).

No air in the system at all, since your using the syringe to force the fluid towards the top, the entire system is under positive pressure. You´ll get a leakage of fluid instead of sucking in air.

No more bleeding is necessary, since your pushing the air towards and out of the reservoir.

It´s fast, easy and doesn´t leave a mess.
Just be sure to unbolt the master cylinder and tape it up so there is a continous rise in the lines all the way to the reservoir. (if you doen´t, some air may be trapped at the junction between master cylinder and hydrallic lines).
