Last year I replaced my Mav brake fluid, I bought 2 bottles of DOT4 about a litre in total.
There was some left over so I replaced the clutch fluid too.
Tip.
get as much out of the resevoir as possible then top it up with new, leave it a while for any bubbles to come out of solution, then start flushing through.
If you spill any fluid on the paintwork, wash off with water straight away, A water spray bottle is best so have this ready before you start.
DO NOT wipe it with a wet cloth, or you will take the paint with it.:doh
