Hey everyone,
I wanted to make a video for people looking to replace all 6 brake lines in their e90 car. Mine is a 330i with 335i front brakes but believe the process is identical in all e90 cars. I couldn't find one good definitive guide with information, pictures or videos about the 2 central brake lines so figured a video on this might be helpful for others. I used 11mm and 14mm open ended wrenches but would suggest using an 11mm flex head flair nut wrench as it will save you ALOT of time and pain. I actually went back in next day with one of these to double check the tightness. Remember to still bleed your brakes afterwards.

Anyway, hope this is helpful and gives people some knowledge in terms of what to expect.
