Default Front master cylinder wiper leaking

I had an issue with my brake switch, I thought maybe something was wrong with the piston. So I popped it out and put a new set in. I’ve tried to push the new wiper in the outlet gap of the master cylinder. I used a extended socket the same diameter and brake fluid to push in. I checked to make sure it’s seated all the way.

When I try to bleed my brakes, I don’t get any pressure with 100 pumps, I see tiny air bubbles coming out of the reservoir with the bleed screws tight. And the obvious sign is with a flashlight, I can see the leak from the ID of the wiper gasket along the piston cap.

What am I doing wrong??? How is the socket damaging the Wiper ID?

Try cracking the banjo joint at the MC, that is where all the trapped air goes. Make sure you cover your tank, etc., it likes to squirt everywhere!
