With ref to below,when all fitted do i just fill up with fluid fit top and pump brake lever as never bled it before.

Yes and no....top up fluid and in sequence of pressing brake lever open bleed valve at caliper to release air and fluid...best use a piece of clear pipe and a bottle. A syringe from the bottom ooh.. er...is best as in pump it up the system rather than down...all of a sudden you have brake pressure!

don't fit the top til you're done, as you need to keep an eye on the level in the master cylinder to make sure you don't start drawing in air there, and have to start all over again....
of course, keep holding the lever in til you've tightened the nipple each time.
get a long piece of tube so that the bottle is higher than the caliper, then the air bubbles climb up it, rather than try to return to the nipple.
and try not to spill any fluid on your paintwork...

Spending 5 minutes with masking tape on the target area before opening the brake fluid bottle will not be 5 minutes wasted.
