Brake dancing. (Olympic Nod)
New booster helped. It was definitely bad. Bled my brakes 'cause all the fluid was Grade-A nasty. (I probably should've done that a few years back). That got me a soft pedal that got firmer after driving around. Not good. I figured since the brake fluid was so bad and had crunchies in there, it had to be a master cylinder issue. As far as I could tell, our master was original equipment. So out with the old, in with the new. Re-bled all the lines. Same soft pedal getting firmer after driving.
That got me thinking about the wheel cylinders. (I probably should've started there). They all looked good last time I was in there. But at least half have been completely submerged in the last year or so too.
I ended up finding three up front that were having trouble retracting after the brake was applied. You can see it in the second photo. All the boots and rubber seals looked good so I just cleaned with brake cleaner and fine emery cloth, smeared on some brake lube and re-installed. Much better. Still some tweaking to do on the brake shoe adjustment to dial the pedal in, but all-in-all it's a big improvement.
Master cylinder from @cruiseroutfit is a real nice unit. They carry wheel cylinders and rebuild kits too. If my quick cleaning doesn't work, I'll probably just order 4 new wheel cylinders for the front and rebuild the others and keep for spares.
