No front brakes

[howzzzit]

Driving a 72 C10 with stock front disc brakes and drum rears. Haven't changed the front pads for years so I decided to do just that. When I pulled off the pads they looked new with no wear. The piston was still pushed in like I would have done before installing new pads. This is both front brake sides. Apparently I've only been stopping on the rear all these years. What should I be looking for?

There's a valve in the lines by the master cylinder that makes fluid go to the front or rear when one end loses pressure. There's a little tool you're supposed to use when bleeding to keep the pin from moving.

I did use that tool recently. I had to replace a rear cylinder. Years ago when I replaced the pads I wouldn't have needed to bleed the lines.
