My MC is level, but I think taking it off and bench bleeding is a great idea--going to work on that today.
One article suggested testing the seals by plugging the outlets and seeing if the brake pedal is stiff. I'll do that as well before I remove it to bench bleed.
I haven't heard about the exhaust issue, but my MC is pretty close, and may explain why the brakes get worse once I drive about 30 minutes. I'll look into either rerouting the lines or shielding.
Thanks!
