Changing brake fluid - how much?

  1. #1
    Sorry if this has been covered / asked before, but i've just had a search and not been able to find anything on it yet.

    I'm changing the front & rear discs/pads in the next week and thought i might aswell change the brake fluid too while i'm at it, as i haven't had it changed since last yr.

    Firstly, i hear castrol dot 4 fluid is a good upgrade? The discs and pads i'm going for are mintex which i understand are an upgrade to the standards.

    Secondly, how much fluid do i need, in terms of litres?

    Help appreciated, rep will be given!

    a litre should be more than enough
