I did the usual the other week, no, replaced the rear brake cylinders. I bled the rear easily as they had new nipples and were well greased I thought I'd replace the brake fluid totally I bled the front offside lower nipple but couldn't budge any of the others. I didn't go for it as I was going away in a couple of days and didn't want to snap them. IF they do snap what's the replacement? Is it worth getting stainless ones? Only for the front calipers as the rear cylinders will need changing again pretty soon What size are they and where best to get them, fleabay??
Stainless nipples are a bit Gothy, don't you think ? Most suppliers sell replacements. I forget the size.
