Got an '01 dyna with Lyndal rotors and pads and braided lines and the rear brake isn't much better than the rear brake on the wife's '08 stock lowrider...do I need to change the master cylinder out to get better rear braking and what's available??? Done the bleeding properly and did the pedal squashed down for a day trick and still no better...

 

Just wondering, is your pedal going all the way down?

 

Bleed it again with a vacuum pump. There is still air in the lines or it is down on fluid.
