Dear Friends,

This weekend I bled my rear brakes with a Mityvac, but couldn't get all the air out of the lines. I sucked out almost 1.5 liters of fluid, but a continuous flow of small air bubbles still remain.

Any thoughts on what I have had done wrong??

FYI, I did exhaustive internet research before I did the job, turned "off" SBC by allowing the car to sleep before doing the job, etc.

Tips or suggestions to other threads I may have missed would be much appreciated!!

Ideally STAR should be used, this may help https://mbstardiagnosis.wordpress.co...g-brake-fluid/

Thanks so much for your response. I see that the Motive Power Bleeder pressurizes the reservoir, and I assume that is what forces out the fluid.

Perhaps this method is better than the Mityvac method to just suck out the fluid at the caliper nipple? And therefore better getting the air out??

I just wanted to close this thread; I did end up getting all the air bubbles out by applying heavy grease to the bleeder nipple. Turns out the air was coming from the gap between the bleeder nipple and the caliper. Suction method seemed to work fine for me.
