HELP! Power Bleeder problems - no fluid coming from caliper bleeder screw/valve!
So, I take a turkey baster and vacuum out some of the brake fluid out of the girling master brake fluid reservoir on the 1991 560SEL. I then place one quart of new DOT4 synthetic brake fluid into my pressure bleeder, then attach the cap to the reservoir, then pump up to 10 PSI.
Fluid begins to spurt around the cap so I check the fittings and retighten to stop the leaks, then wipe up the slight fluid spill. It appears that the new fluid has entered the brake master cylinder causing the fluid level to rise.
I then go to the right rear caliper and open the bleeder screw. NO FLUID COMES OUT!!! WHAT AM I DOING WRONG?
