Couple of years since this thread started but I think it’s a fair working hypothesis at you should not expect more than than 3 years from the ‘rebuilt’ brake calipers from

Parts store chains?

Note -,seeing VOLVO on your rebuilt is false hope, the lifetime is determined by the parts used, not the core

Always keep the factory caliper slide pins even if your caliper is frozen rusted to hell etc. The factory pins are stainless and last forever - just sand them if they get pitted. The rebuilts tend to use the silver cheese metal slide pins.

Add Volvo to this list. I have posted about this in detail in the past including detailed pictures, but here's the summary:

My V70 suffered five caliper failures in five years, all using rebuilt calipers bought and installed by a Volvo dealership. Each time, the piston had seized in place either open (no breaks) or closed (brakes applied). I believe they each failed after about 30k miles and ~3 years. After the final failure, I removed and examined the caliper to find the dust boot wasn't fully seated. This allowed moisture in, rusting the piston, expanding it so it jammed into its hole in the caliper.

I bought a Volvo rebuilt caliper from FCP (so if it fails, they'll replace it for free!!). Before installing the caliper, I carefully examined it, even using shop compressed air to partially expand the piston so I could inspect the dust boot. Just like the failed one, the dust boot wasn't fully seated right out of the box. I used a small flat screwdriver to carefully press the boot back into the groove in the piston. Without doing this, moisture would have entered the caliper and rusted the piston.

MVS user cn90 posted this great thread about break caliper dust boots. I've attached it as a PDF (because that's how I save great threads for future use).

Now, I inspect my caliper dust boots once a year. I take their pads out, replace them with thinner blocks of wood, press the pedal to ensure they extend smoothly, then use my break pad spreader to press them back into the caliper to ensure they retract smoothly. I can see only some of the boot while the piston is extended, but testing for smooth operation lets me know if there are any problems.

Buy Volvo rebuilt calipers, pads, and rotors from FCP. They will pay to replace any caliper they sell which fails due to poor rebuild quality, including the break pads and rotors which the caliper ruined. I told them to complain to Volvo about the improperly installed boots since they're paying for it. I really hope they did.

Sorry abescate, the V70 I donated to you has three seized calipers. I think only the rear left is functional because it was never replaced. All the others are high priced, Volvo rebuilds probably with failed dust boots.

Neil recommendation on aftermarket calipers...Nugeon brand from NaPA

Clean and grease the slide pins when you're checking the dust boots, will add years to a rebuilt caliper. Or stop cleaning them if it is time for an FCP warranty swap!

Are you talking about front break calipers? Where are there pins? My 2000 front calipers have grooves which the pad ears fit in. I grease those grooves. The rears have pins which go through holes in the pads and calipers. I grease those pins as well.

I hope I'm not missing something. For the first time in longer than I can remember, I have all four break calipers, pads, and rotors functioning correctly. But I don't know about those parking breaks possibly dragging in the rotor hats...

The caliper slide pins are the bolts you unscrew to remove the caliper
