Squishy brake pedal. But no fluid change or drain

Agreed. The self adjuster rarely works properly in most cars and especially not in the Yaris. Is recommend adjusting every 6 months depending on how often and how hard you use your Yaris

That's exactly what my issue is. I think adjusting them now

Also I have the disc rear axle beam part number if anyone cares... I want disc rears just cause haha

A late update:

I adjusted the rear brakes manually, and it fixed the problem. They have returned to their previous feel. Also took the time to clear coat the shiny metal drums. Hopefully that clear will hold up over the long term against the rusty look.

I'm going to guess some how air got into the system. Not really sure how that's possible, but a squishy brake pedal is a sign of air being in the system.

Do a brake fluid flush with some DOT3/4 fluid, and see how it feels then. It's probably due for a flush anyway. I'll be flushing mine (probably with the gravity method unless I can have someone help me by pressing on the brake pedal) soon. I've flushed it once already, but I used Torque RT700 (DOT4), but it's changed color quickly (even became a little jelly in my FR-S [sucked out and topped off with new fluid for now]). I have some Amsoil DOT3/4 waiting for both cars, just need the time to do it.

When I bled my brake, I cut a $2 1/2" pvc pipe from home depot, pumped the brakes, placed the pvc pipe between the brake pedal and the seat, and made sure to place a cardboard piece between the seat and the pvc pipe to avoid any damage. Seemed to work well.
