Hey all,

I recently replaced the Master Cylinder, all rubber lines, front calipers, rear wheel cylinders, pads, shoes, two new drums for intermediate axle, new springs inside the drums. The issue: I get GREAT pedal feel when the engine is off. Can practically stand on it and feels very firm. Virtually no downward travel before you hit the 'firm' wall. However when you start the engine and drive, the pedal will travel about 1/3 of the way down before it starts braking (then the coach does stop well once the brakes actuate), then when you release the pedal, it returns upward only until that same 1/3 point, then is VERY slow to come all of the way back up. The other day, the pedal would not come up at ALL. It stopped just fine, but I had to keep my left foot nearby in order to pull the pedal back up to get rolling again. That lasted for that short drive, and now today it is back to 'normal' - 1/3 pedal travel, and slow to return to upward position. What could be causing this?
