Front brakes still locked up

[Rough75C20]

Replaced master. Didn’t fix my issue. Pissed off i started troubleshooting. The person before me rigged up the brake light switch such that the pedal was being stopped by it and slightly pushing the master cylinder piston.

Just wanted to update before someone else has this issue and replaces master without needing to.

Cheers!

...Still, ensure the brake pedal is fully returning and not hanging up...

...The pedal does return to the full home position after pushing down on the brake....

You said you checked for that.   

You're not the first to be tricked by a rebellious brake light switch, so don't be too harsh with yourself.

Thanks for your help bd. I did check to see if the pedal was fully returning to the point it was bottoming out on the switch. At the time I assumed this was as far as it was supposed to travel. You live and you learn I guess. I appreciate the help. Could be worse, at least the components are new now.

Cheers!

PSA: If you are a parts hoarder, keep your old unit, and buy a kit for it....they don't make USA-made master cylinders anymore.
