Got the MC installed, all lines attached.

Watched Ian Karr's video.


Started to bleed, seeing old brake fluid and lots of bubbles, after about fifteen minutes of this I am not seeing a stream of fluid coming down the clear plastic tube. Yes the end is submerged in brake fluid. Checked for leaks at the MC and dry as a bone. Check inside car and dry also.

I have never done this before so just wondering and asking for suggestions, ideas and don't do that.

Thanks

Renee

I couldn't get the air out until I replaced all of the bleeder valves with speed bleeders.

Try the long hose method. Attach a hose at the bleeder valve and then run it back to the reservoir. Makes it a one person job. You can sit in the car, pump the brakes and watch the lines to monitor when the bubbles are gone. Plus you don't waste any fluid because you're routing it back to the reservoir.
