Just a quick one,
I'm away from my car at work so can't check and need to get me the correct size spanner to bleed breaks.
What size are they??
7mm?
 
On my S3, the brake nipples were M10 and required an 11mm spanner.

Safest to get a set of metric from 6mm up, they're not expensive?
 
11mm.

You'll want a 3/8 ratchet and a deep socket to shock them open with maximum purchase and safety if they haven't been cracked off in a while.

Otherwise you will risk rounding them.
