I expect it is likely the wheel cylinders. What I can't figure out is why both failed together, and both seem to be increasing the level of leaking in lock step.
Wharre to hammer the things to get them off. I tried with my 2lb short sledge to sort of tap them, then tried knock them off using a screwdriver to trasfer the blow to the lip of the drum. No luck. Lot's of penetrating oil around the hub to break up any rust. No results.
