I finally installed a 19mm MC to match the SC front brakes I installed last year. I have new brake lines front and year. No leaks anywhere that I can tell. I used a pressure bleeder with ATE Super Blue. Bleed brakes for 12 rounds and still am getting bubbles. Pumped brake pedal hard in between each round to free up any air trapped in proportioning valve. I bleed the MC connections prior to bleeding each wheel.
When I first push on the pedal it goes down quite a ways. second pump is much higher and stiffer but there is still some sponginess. Any suggestions?
thanks,
