I would suspect contamination in your lines some where. What brake is coming on?

Are they coming on without touching the pedal at all, or just not releasing after they've been used?

If they're coming on without touching the pedal at all, I'd suspect a bad vacuum booster.

If they're not releasing after they've been used, I'd suspect a bad brake hose that's swollen shut.

same problem I have... I have SSBC disc on all four. After 20-30 minutes....same deal!

What's up?

Make sure the rod from the brake pedal to the master cylinder is in the right hole and not binding up against the firewall.

The right hole and not the left?
For real, which hole and how many would there be?
