Glad I did my brakes because....

They were stuck on my '91 Nissan that had been sitting in a barn for 4 years. I was replacing the calipers anyway so I just took an oxy/acetylene torch to them. They can't be stuck if they're a liquid.

Two thoughts, 1) it had been a really long time since the caliper pins were serviced 2) someone used the wrong grease on the slide in and the boots for the slide pins swelled and no longer were properly sealing the pin to keep dirt and water out.

How were the pins? Did you get new pins? Boots for the pins?

I bought new pins from Rock Auto but they were too loose in the calipers so I cleaned up the old ones. No new boots

Which car? I would guess either one in your list had the brakes done once or twice.
Did you do them?
The boot must have been torn or not over the lip allowing moisture in.

To answer your question. None that I recall. And none of my cars and they get minimal brake servicing.

I did have one rear outer pad fail on the 2017 crosstrek and it was thin enough to jamin between the rotor and the bracket frame "window".
I think the pad ears were missstamped oversized a bit. I even had to file-fit the new ones.
Shims and bracket were brushed clean.

They were non ceramic, metallic cheapo duralast pads from autozone. Never has an issue before with
the cheap pads other than a bit of rotor chewing and dusting.

My Avalon. First time I have touched the brakes on this car. Old man had it before me.

Two caliper slide pins on two different calipers were totally stuck in the caliper brackets. At first they wouldn't slide/turn. Lots of heat, PB Blaster and time finally let me get them out. Of course they were the pins with the little rubber seals on the end.

How many times have you guys run into stuck caliper pins?

several times a week in the last 8 years. though to be fair the last year or so it was more like every couple weeks, guess I went through nearly every customer's car by then, only dealing with newer stuff.

In the 'rust-belt', it good to do a Brake Maintenance every two years.
I always feel better having an extra Hardware Kit (or two) just in case their needed.

TIME is MONEY + some shops neglect doing little things that count!! i am slooo but efficient + picky + my DIY rates are FREE! you gotta know if your service is correctly done BUT since you can only watch from a distance in most shops by law you gotta believe YOUR guy is doing it right!!

I think shops in a hurry are likely to reuse a pin that has some rusting rather than replace it. That may lead to it sticking in the future.

Or else the pin was seized to the caliper assembly and would have meant replacing the entire caliper assembly. Just like this assembly with one good pin that was well lubricated and one pin that was not and was seized to the assembly.

Yep, have a look at my photos in the posting above. I couldn’t remove one of the pins, so I cleaned it the best I could and re-lubed it. Notice the boot separated on that one.

Well I would think many shops would love to find a reason to replace the caliper.
