So been doing some reading around about my brake problem with my crx when I switched the fronts to the 91 DA rotor, spindle, hub, caliper bracket, calipers, MC, BB, and now we can't get the brakes to bleed. We found something knida odd though. Not sure if it's suppose to be this way or not. We hooked up the line near the MC to our air hose to blow air through after we've tried bleeding them like 15 times, and numerous different methods. When we blew air through one, it would send air out of the front left, and the back right, when we switched to the other line near the MC it sent air through the front right, and the back left....is this normal? or did someone do something to the brakes previously and mess that up? Shouldn't it be one line will blow air through both fronts and the other to both rears? Another thing I was wondering is with my regualr EF rear drums, and the DA big brakes up front, so I need the 4040 Prop valve...or should the one that came on my CRX work? Thanks for any help.
