....and remember brake fluid really does need changing every couple of years (or more often) due to absorbing moisture from the atmosphere.
If you see old brake fluid you'll appreciate what it means.
I'm fairly sure Halfords branded stuff is actually Castrol (or at least it used to be). I use Halfords brake fluid too, any of the DOT4 types is fine. If you aren't familiar with the DOT5/DOT5.1 differences just steer clear of them!
