Sorry for the new thred but this is a more specific question. Set about bleeding my front brakes today, did one whole cycle of master, right and left. And then I think I let my master drop too low. As a result of this or whatever it is Ive done, the brake lever no longer has ANY braking. I believe Ive got a lot of air in there :/ Im looking at doing a reverse bleed tomorrow morning when I can get my hands on a syringe. Just wanted to ask if this was the right course of action. Do up all bleeders except the caliper Im pumping in from, pump in and remove fluid from resevoir as it comes up Thanks PS. Also, should engine oil level be checked when the bike is warm or cold.
