Can also just throw some warm water over the calipers to neutralize any residual brake fluid.
Yea crap - I had a second thought that it was maybe 11mm but whatever.

You'll need:
- Power Bleeder
- Catch bottle
- Motul RBF600 (or your choice of DOT 4 fluid - RBF600, RBF660, or Castrol SRF). Minimum of 2L, but get 3 to be safe.
- 11mm wrench (for the bleeder screw)
- Turkey baster (yes, really)
- A floor jack
- 19mm socket + breaker + torque wrench for the wheels
- (optional) Jack stands or QuickJack to get all 4 corners up at once
You are the absolute best, thanks for taking the time to write this up! I was concerned that we needed those OBD tools to open a valve or something, but this seems pretty straightforward.
Good on the tip of the quantity, I was planning for 1.5L only as I had read somewhere else.

Thanks again!

I think the amount is something like 2L in the whole system, but bleeding it through is not an "exact" science and if you bleed too much (and you should never re-use it) you're going to inevitably bleed through more than the whole system contains.
