About 2 weeks ago I thought that I would try and change my brake fluid because the braking performance of my bike was (at least to me) less then satisfactory and the performance changed. Sometimes I would be pulling up to lights and the bike wasn't slowing down as much as I needed so I had to release to brake and pull again. I didn't read up much on it, just open nipple, reservoir and bleed top up. I did this and got no back brake and through a process of trial and error I got rear braking again with less performance then what I started with. There wear little bubbles in the bleed hose that would just keep on coming through, I was thinking that I might be in need of new hoses. Also I had trouble getting the bleed hoses on the nipple and had a few drips to clean. I didn't do the front at the time because I wasn't happy with the first attempt and wasn't to sure if I needed 2 bleed kits as I had dual brakes. I think I took about 30 min to do this and would have given any person that knew what they were doing watching a good laugh. Today I decided to read up on bleeding and the order and a few tips etc. Did the front brakes in maybe 5 min. Back about 5 again. I have taken the bike for a ride with e-braking and they are working much better and the front brakes are nice and consistent. A few tips that I picked up: Never let the master cylinder go empty when bleed as you just let more air in have the bike close to vertical esp with the front have a rag Aluminum foil is pretty good for catching drop as material rags seep through. Beer is needed Don't need 2 kits for the dual front brakes. (I did a bleed on both separately just in case I don't know if that's needed or not) Finally don't let your fluid get like this Oh and finally, since bleeding isn't needed often and fluid goes bad not long after opening. I have half a 500 ml bottle of ferodo dot4 is someone wants it.
