long story short, I need a new master cylinder and I don't have the old one for a guide.
Was about to click buy on a dual resevoir and noticed at least 2 different bore sizes available...
If I don't have the original, which one do I get? Does it matter? Currently have drums all the way around with no intention (in the near future) to convert to disc.
Do I need a proportioning valve?
Couldn't find much on a quick search, sorry if this is already out there somewhere.
