No Brakes!! Please help...

[TrqMnstr]

Well I was driving home today and my brakes decided to act up. Brakes hold pressure, but if held on lightly the pressure just goes away. Their are no visual signs of external leaking. So my best guess would be that the BMC is no good?? Any thoughts?

when you say the pressure goes away, do you mean the pedal drops? If so id replace bmc and bleed thoroughly (thats if you're 110% sure theres no leaks and no air in the lines already)

There could be air in the lines. Bleed the system and see if it still does it. Are you losing any brake fluid?

Yes, the pedal drops. No leaks whatsoever.
