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.

Using a motive power bleeder? I’ve never had to separately bleed the MC or proportion valve. I do it a bit different, but not so much.
When replacing a caliper or MC, i go though this process: Fill power bleeder with 2 liters of fluid (or more if you take it slow), pressurize and open all bleeders. Close them off one by one (bottom then top on each caliper) as bubbles stop at the caliper (I go closest to furthest). You’ll need to keep pressure up on motive watch fluid level. Once all are closed off, go around and tap all calipers, MC, and P-valve with rubber mallet. Then bleed one by one, bottom then top bleeder, furthest from MC to closest i tap the caliper with the mallet as i do this. |
