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.

Except for DOT 5 (which is silicone-based), brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This property can lower the fluid’s boiling point, leading to issues like brake fade and reduced performance under high temperatures. Water in your brake fluid also promotes corrosion.
As a regular part of maintaining your 914, you should flush your brake fluid to address this issue. So, you should avoid recycling old brake fluid into the reservoir during the bleeding or flushing process as the water present in your brake fluid will not get purged. +1 on the Motive bleeder and there are YouTube videos that document how to use one. Works well and you can bleeder your 914's brake system without a second person. |
