couple of Qs:
1. what is the fettling required and does anyone have pics to highlight the issue and the fettling required - I've also heard that the caliper in situ is very close/fouls the disc ? is it really a straight swap - I'm not mechanical and have few mechanical tools , most of my stuff is for electrics
2. I've got 4 litres (2x2) brake fluid that I opened about two years ago and only used a bit. Is this no good for replacing brake fluid (after I do this mod)
As fizzy pies said, almost a straight swap. The issue is that on the standard 600 caliper bracket mounting holes will not line up with the Blue spot caliper they are about 1.5mm out. Filing about 2.5 mm off the bracket to get them to fit, this will also give a little clearance for any heat expansion issues.
Emijaydee has some pics when he did his in April http://foc-u.co.uk/index.php?topic=12420.0 It is difficult to see if he allowed any clearance from the pictures.
The original is quite a good caliper, but the drain holes block to easily holding winter salt laden water in the caliper for longer, thus allowing corrosion to take a hold if they are not cleared regularly. Bue spot caliper does not have the problem as the pads are removed from the bottom and does not rely on drain holes to drain off the water.
In reply to your brake fluid question, I would not use an unsealed one after 2 years, but a sealed one I would use.
