Thats what I was curious about
As a test a few years ago I removed the return springs, A member on this board speculated that you should not need return spring. That the MC would return the pedal.
This was incorrect.
The return spring was needed to activate the stop,switch arm.
When I did this test the brake light stayed on.
Sounds like your issue is with the MC.
But the brake pedal should still return
Just a troubleshooting suggestion
