Potential Really Really Bad Time? Rusted Out Rear Control Arm(?) +Seized Caliper Bolt +Introduction

Hi first post you may call me gobert

2011 Gen 3 Trim IV 126,xxx miles

Attempted R brake pads. Seized caliper bolt led to searches, realized no turny cube. Also noticed chips of rust falling out during my struggle. Originally thought the holes were OEM but it looks kinda bad. No offense to anyone but I've seen prettier.



How f*k'd am I?

Also, the parts diagram catalogues online for this car aren't very good and I'd appreciate it a ton if somebody could provide a part # for the caliper bolt (in the pic) and/or a reference for where this information is available in a more usable way.

Help me Prius Jesus (yk who you are, I been lurking a bit) you are my only hope.

Ah tried to post. Gotchaaa.

The rusted holes aren't in the caliper/rotor or any of the brake assembly. The chunk of metal for which I have correctly or incorrectly deemed the control arm is the rusted out part. Where the rotor and dust shield, as well as the caliper are directly mounted.

 

Emailing you right now, thank you sir. It's not really what appears to be a dire emergency, just something that may or may not be catastrophically expensive at some point. I'm not having issue with the brakes themselves, aside from that single bolt (in the pic) that I'll have to replace.

 

Ok, update.

The "potentially catastrophic whatever whatever" was pure schizophrenic ravings and ramblings that apparently arise within me when frustrated about being unable to free a seized bolt. The "rusted out" holes in the control arm, while rusty, are not what I thought they were, and the holes were manufactured, lol.

The bolt that gave me 2 full days of trouble though... well. I let it soak in the PBB overnight while waiting on an amazon care package, including: an enormous breaker bar, those flower pedal shaped, sharply rifled sockets intended for "eating into" seized and rounded off hex bolts, and swivel joints, extensions for my impact.

All of those tools, somehow, were to absolutely no avail. I was indeed turning it the right way. I wasn't somehow impacting, breaker bar-ing, or Peanut Butter Blasting it wrong, idk man, honestly.

But in my dejection I realized that the bolt was only holding the bracket to the thing, and not the caliper to the thing. I could've just wiggled the caliper free the entire time HAHA.

Lesson? Idk watch a video or something idc whatever doesn't matter.
