Going to be sorting my brake master cylinder soon - can anyone confirm that the size flare spanner I need for the brake lines is 11mm? I went out to check on the car and for some unknown reason, my spanner set jumps from 10mm (which was too small) to 13mm (which was too big) so couldn't make sure.
While I'm at it, I'm thinking about changing my brake lines to braided hoses. Is it worth it? If I'm going to be bleeding the system anyway, it's something I may as well do all at the same time. The existing lines are fifteen years and 160k miles old, and if it actually improves braking, so much the better...
