bleeding brakes is a 20 min affair. very easy. Most fluds are Dot 4.1 or similar, dont be tempted by dot5 as they tend to have a short service life.
I woulld recommend a complete flush, buy a bleedig kit, or borrow one from me, from halfords. oh, and buy the new castrol synthetic brake fluid, its superb as it lasts ages before absornig water. its sort of a light violet colour fluid...in a silver bottle.
anyways, do the fronts and back, following the sequence in you haynes....but have somebody pumping the pedal for you, whilst you make sure the fluid level doesnt fall too low or you might suck air into the brake system. can give you a hand if ya want.
