Something just occured to me that points that the MC may be the problem. 1st thing I did this morning was a test. I opened a rear bleeder valve and stepped hard on the brake pedal, thinking that if the piston in the brake valve was stuck in on the front side that this might push it back. It had no effect but the brake warning light did NOT come on either.

I think the brake warning light didn't come on because the front brake side of the master is not making proper pressure. I found another master and should have one tomm. instead of Tues.
