MC Pushrod Removal

If you use that method, be careful you don't break the brake light switch. I'd recommend you remove the switch before doing it.
Exactly.
Don't try to pry out the pushrod with master cylinder in the car. It is REALLY in there and takes alot of force to remove it. You will dent the firewall or ruin the brake light switch.
If you ruin the geometry of your braking system, get ready to replace everything.
