Hi all, With a spongy front brake I started with the obvious brake bleed but that didn't help things much. So I ordered a master cylinder kit which arrived and looked to contain all the right bits but on measuring the old and new, the new one is about 1mm smaller in diameter so obviously won't fit. So I ordered another kit from a different supplier and have the same problem. Are there 2 sizes? The bike does not look like it's been mucked about with, but I could really do with some kind of front brake. Any suggestions or advice? Cheers!
