Ok, so I just installed new brembo slotted rotors and steal braided brake lines on the front and I'm still waiting to get my rear rotors in. Now when I litely tap the brakes the pedal is real mushy but when I hit them really hard and completely stop the pedal get real stiff. Also after heavy braking and sometimes even when I brake normaly the pads keep rumming on the rotors. Oh and I've bleed the brakes at least 3 or 4 times already. Anyone know what I can do to fix this?

 

Mushy = air in the lines somewhere. Are you using the right bleeding order?

And without the rear SS lines you will not have the nice firm brake pedal.

 

If you didn't have any of those problems before you did the work recheck everything you did. It almost sounds like a bad master but if it just started after you put the new parts on it could be a twisted or kinked line.
