Attempted first brake job - Broke a pin in the caliper bracket
Hi everyone & merry Christmas! The weather in NY is super nice today and tomorrow, so I decided to attempt my first brake job. Rear Pads & Rotors on my 2008 4Runner Sport V8. My trusted mechanic said it's getting pretty tired underneath so it may not be worth putting much money into. Thus, I decided to try to DIY...
This one rotor pin bolt was super stuck, wouldn't break loose with an impact with an impact swivel so I decided to go old school with a breaker bar. The breaker bar, with a cheater bar broke it loose, unfortunately it sheared the pin off in the caliper bracket. I've tried quite a bit of PB blaster, attempted to beat it out from the other side with a punch that ended up bending, and I attempted to drill it out, but gave up on that too. All of the pin boots were also completely trashed. I've had the caliper bracket cranked in a vice multiple times while trying to beat the pin out. Is my best bet just to order new caliper brackets, pins, and pin boots/bushings for both sides? I'm pretty new to this DIY thing, so can you check what I think I need?
Rear Left Reman Caliper Bracket (current brackets seem to have 14BD & R22 etched into them)
Rear Right Reman Caliper Bracket
CARLSON 16005 Disc Brake Caliper Pin Boot Kit (x2 sets)
DORMAN HW14044 Rear Disc Brake Bolts (x2 sets)
I'll see if anyone local has these in-stock tomorrow, but want to make sure I'm on the right path!

Try inserting good pin from the other side and use as a punch.

Go with replacements, it will make the job easier and probably better in long run.

Replace... for the $50-60 for a caliper (what I've been paying at NAPA for their lifetime remans as I've been re-doing my brakes, I believe), it's just easier and more cost effective to swap the whole thing. I don't think there are different variations for the rear on a 4th gen (unlike the front).

The best way to get that out is by welding a nut onto what's left. Otherwise get a new caliper. Make sure you get all the parts you need as there may be variations as to what it comes with.

Alright here's the update and the final problem that I'm not sure if I adequately overcame. Bought new brackets, new rubber hardware, and new pins.
When I was previously taking everything apart, I found it odd, but didn't think much of it, that one pin loosened, but didn't zip out of the caliper. I ended up having to pry it gently with a screwdriver as I backed it out with the impact. I also noticed what I perceived at the time as really small and spread out "springs" came out at the same time. I thought maybe there were springs embedded in the rubber bracket hardware that were so trashed they just came out of the rubber.
Putting it back together, the caliper pin bolt threads into the caliper, but after a snug tightness then loosens. I can repeatedly tighten it, but once I tighten it to a certain point it loosens. I wonder if the "springs" that came out were some of the threads in the caliper? I'm not in a position to replace the caliper myself, I'm working on my stone driveway in the middle of winter and I also don't know how to bleed brakes or make new brakelines if needed.
My temporary (?) solution was to go buy orange Loctite (strength of red, doesn't vibrate loose, but can eventually break loose with standard tools like blue). I put orange loctite on the thread of the one pin and tightened it to the tightest possible point before it would break loose. I'm letting it fully cure for 24 hours before I break the brakes in. If I'm estimating based on the torque wrench on the other pins, I'm going to say it's 30-40lb of torque + orange loctite.
This is not my daily driver, I use it to plow my driveway and drive to work on ~5 of the snowiest days of the school year. Am I OK monitoring this "fix" or do I need to immediately have the caliper replaced? the other pin bolt is torqued to spec. The pin with loctite doesn't pull out easily even when it's broke loose, I had to pry it with a screwdriver.
Thoughts?

You should be fine for as little as you use the vehicle....BUT I would replace the caliper when you can.
