[T3] Brake Bleeding

[J. Jonik]

After replacing two rubber brake hoses (RF and RR), assuring that there's no leaks anywhere, adjusting rear brakes a few times (to be sure), checking that all brake pads are up to spec, and bleeding brakes today...twice...with two mechanically-competent people with actual feet....the brakes feel somewhat better....But they are still not right.   First brake push needs a 2nd or 3rd push to feel right. 

These are not brakes to use effectively if a deer jumps in front of you on a dark road.
Both of today's bleeds (with actual feet, not just the stick-against-seat trick) got good, got serious (no air evident) fluid squirts from front caliper valves...but just one little air fizzle from LR, and then just what might best be called "leakage" of fluid from both rear valves. Rear valves didn't squirt.


Why didn't rear valves SQUIRT out fluid when brake pedal was depressed as far as it can go?  Where's the pressure?  Again, RR brake hose is brand new....the LR to be replaced as soon as UPS delivers new hose...doesn't even look old.

How to know if this is, or is not, a Master Cylinder problem?  I'd hate to have to replace Master Cylinder "just in case".
