Yes the bubbles are clearly visible through the tube on the bleed kit but there isnt much in the way of a spongy pedal and there is no leaks anywhere. I have tried bleeding the brakes with the bleed nipples in various stages of unscrew to see if i t was just dragging in air at the nipple but it doesnt seem that.

I am swaying more toward the discs being warped too because on top of the car juddering under braking the brakes feel as if they are on off on off in very quick succession. Are hi spec discs crap? Because these things are bloody brand new
