How about connecting a long piece of .25" (or suitable size) hose to the bleeder screw and put the other side into your reservoir and keep pumping and watch the fluid get cycled thru. This will make bleeding easy and perhaps the bubbles make themselves thru eventually.

Default disconnect the lines

I disconnected the brake lines between the pilot and copilot master cylinders and bled one side, then connected the lines and bled the other side.

Cool BRAKE BLEED

I HAVE HAD TO BLEED SOME MATCO BRAKES FROM TOP DOWN. USUALLY ON A RV-4 THAT HAS THE MASTERS MOUNTED UPSIDE DOWN. I INSTALL A FITTING ON THE RES. AND PRESSURIZE, THEN OPEN EACH BRAKE BLEEDER. MAKE SURE BOTH PEDDLES ARE PULLED FULLY BACK.

That's the way Piper installs them on all of the pa 28 models. And you do bleed them from the top down with no problems. When I rebuilt my master cyl's in my Piper (5 of them) it took me about ten minutes to bleed the brake system by myself..................

When they are mounted "up side down", to rebuild them all you have to do is remove the one bolt on the end of the shaft and remove the snap ring and pull the entire plunger out of the body without removing any of the fluid lines. I think it is just a better way of installing the cyl's.

Why did Van mount them the way he did on the 6,7 and 9???

Smile Just to let you know....

I think (fingers crossed) I finally got all the air out of the system. But it wasn't easy. When pumping fluid from below, those darn bubbles would come down the tubes, appear to enter the bottom of the clinders, but not come out the top. Air seems to get trapped in the cylinder. No amount of tapping, repositioning, pumping, etc. would push those bubbles out. Finally expelled the air by positioning the bubble right at the bottom of the cylinder, then loosening the tubing connection enough to let out the air and some fluid.

Man! I hope those bubbles don't come back tomorrow!
