Rear brake felt spongy the day after bleeding. Went for a ride anyway, lifted the hood and saw a bit of mineral oil residue, seemed strange because I swore I cleaned it carefully. Depressed the lever and saw tiny bubbles emerging from the hole in the red circle. Cleaned and dried thoroughly hoping it was just moisture, waited a few hours, same issue so I assume it's oil. Any idea what's happening and if it's repairable?

You’ve blown the diaphragm. New one can be ordered but you’ll need to bleed the brake again.
