Hey Dudes, Sean and I did a brake fluid flush on Sean's rig. The FSM does say to immerse your drain tube into some brake fluid and I've also seen other videos like from Chris Fix and Eric the Car Guy who say this step is necessary. I had never heard of this before doing the flush on Sean's rig and I honestly don't think it's necessary. If you do everything correctly, you should not pull any air into your brake system. My thinking is this, if it were actually crucial to do this step, than you would technically have to start off with your drain tube evacuated of air as well.

Anyway, I would like to hear some comments regarding the whole drain tube immersed in brake fluid. I've never done this and I've always had good results with my brake bleeds so I'm taking the position it's not necessary. Maybe it's more of a back-up in case the person doing the brake pedal pumping lifts up on the pedal before you had a chance to close the bleeder.

Enjoy the show!
