Brakes are going in and out of working.

Brakes were working fairly decent but going down the road all of a sudden it felt as if I just had the REARS working only. Pedal went down further(no pressure) and only lasted for a few miles. Then the brakes suddenly re-appeared but not great and this is kinda scary.

Just put on a new MC, dual 8" booster, new rear wheel cylinders, new proportional valve, and bleed the hell out of it.

No apparent brake fluid leaks, plenty of shoe on the rears, and no issues with the front rotor/pads.

Any ideas? I'm thinking I may have a nasty vac. leak somewhere but anything else?

Thank You!

I think your right. I just couldn't believe these needed to get bled again but the pedal going down more to the floor would indicate a loss of internal pressure and not vacuum, correct? It just weird how they came back sorta about 2 miles later.
