Thanks guys. Leaks have been identified, corrected and fittings are dry. I spoke with both CPP (supplied MC, booster, and prop valve) and Brothers (supplied disk brake conversion kit). CPP agreed that the clamped hose test means no air in system from pinched hose to MC (due to hard pedal with all four brakes pinched off). Was not too worried about possibility of air in short line that goes up above MC fluid level and back down to prop valve. Suggested I bleed at prop valve fitting just to be sure. CPP wants me to adjust rear shoes tighter. Basically adjust so wheel will not make 1/2 rev by hand. Then leave it that way without backing off adjuster. CPP is concerned about flex in front caliper and mounting bracket. I will inspect to ensure pads are contacting disk square. Talked to Brothers about this as well and they want me to inspect caliper casting and pin to ensure caliper is moving on pin properly. CPP also wants me to remove caliper for bleeding and insure bleed valve is perfectly at 12:00 position...its more like at the 12:30 position while mounted.
Here is how system is plumbed:
Front (actuator rod end) MC reservoir/port is plumbed to rear inlet port on prop valve. Rear MC reservoir/port is plumbing to front inlet port on prop valve. front outlet ports on prop valve plumbed to calipers (one for each, no shared line). Rear outlet port on prop valve plumbing to rear "T" on axle. "T" plumbed to each rear wheel cylinder. There are no residual valves installed in the system. Both CPP and Brothers said not absolutely necessary and will only result in more immediate pedal, but will not fix spongy pedal. All hard lines are 3/16".
So, my plan of action. Tighten up rear shoes. Pinch all hoses closed and ensure I still have hard pedal. Release rear hose, check for firm pedal. Inspect and correct caliper/disk alignment issues, if any. unclamp one caliper hose at a time and fix pedal feel before unclamping other/last caliper. Fix pedal issues with last caliper.
After that, if I still have issues, I am getting my shotgun out.
