Lost back brakes

This is all very interesting.
I've had exactly the same problem with the front brakes for years, bleed them, they're good for a while then lever back to the bars again, repeat ... repeat etc.
Some one said fit two individual front brake lines, did that, no difference.
Stripped and cleaned the entire system, no difference.
Just last weekend I re kitted the front master cylinder, waiting to see if that makes any difference.

Also have bought a second hand front master cylinder, just to see if swapping that makes any difference.

Am holding Sonny's thought about the bleeder screws ......

Has anyone tried to replace the front rotors buttons? A set of new EBC rotors is $200 but, I wonder if I can rebuild the originals for $50.

The rotors are stamped with Min. thickness allowed.
