Start from the furthest point from the master cyclinder and work your way forward from there.
So it will:
Rear left
Rear right
Front left
Front right.

Remember that Brembo calipers have two bleed nipples...

Yep there's a couple of really good videos for 06 sti brake fluid flushes but they are American and the brake master cylinder is on the other side of the engine bay so just wanted to make sure I got the order right. The hoses that connect to the nipple to drain the fluid I assume are sold by supercheap, autopro etc?

I just use a plastic container with clear washer fluid hose

Any suitable plastic tubing...eg Bunnings spec.

Thanks guys. This will be my first diy over and above an oil change so don't want to fuck it up :thumbup:

Did this today with a mate. Was really easy and took less time than we thought. Old fluid was not that bad but could definitely see the colour difference. Brake pedal feels a tad firmer too. :thumbup: for anyone considering doing this you need an 11mm wrench and 6mm tubing.
