I am replacing slide pin boots on every brake pad change

I get them for my Mercury at Rock Auto.
Pin boots can be easily torn when removing them as rust can hold them in place, and I suspect that’s what caused the damage. Someone being careless during removal.
The seal between the glider pins and the boots is critical to avoid having to replace a caliper bracket. I've replaced several due to water infiltration and rotting of the sleeves.
I now get a bit aggressive on removing the rust/oxidation around the lip of the sleeve to ensure the boot gets a really good seal. I also ensure the Silicone brake grease I use extends over the lip to ensure an airtight seal and to prevent corrosion for the rest of the interval.
I don't always replace the boots if they inspect ok. But definitely if there's any deformation or swelling or compromise/tear.

Yep, that rust around the sleeve lip needs to be managed. I used to add anti seize around the base of the sleeve lip, where the boot attaches, but I use that Silicone brake grease and just extend it over the lip and give the boot a good few rotations after installing it to seat the grease around the base of the sleeve. Since I've been doing that my boots slide right off every time.
Molykote 111. Find it on Amazon. Grainger can also order it, your local dive shop also has it as Trident Silicone Grease.
Personally, I would use Sil-Glyde or Toyota rubber grease. Anything that isn’t Permatex or CRC brake grease.
Slide pins should be replaced if they don't look pristine after wiping them off. Don't use a wire brush or emery cloth, rather replace if any rust or putting.
Some disc brake lube can swell or damage the slide pin boots. I only use Syl-Glide.I may not always replace but good to have spares on hand if needed.

Doing a brake job next weekend, you guys just convinced me to pony up for new boots also. Good thing they are cheep.
I don't replace pins, I clean them, lube em, stick em back in. Make sure the boots are good.

Ive found that most of the binding comes from not only the lack of grease but from rust buildup in between the boot and the caliper. I always clean the hole with a wire brush and knock the rust off the center of the boot.

Another trick is to sort of "pack" the boot with some grease. It will add a barrier from any water intrusion. And by pack i mean just clean the boot out and then get a liberal layer where the boot contacts the parts.
Don't cheap out on the boots.
I also like to replace boots when replacing brake pads. But some of the hardware kits I have bought from Rock Auto have had boots that feel super thin, especially when compared to the boots that were being replaced.
Never replaced slide pin boots. Yet I would if I lived with lots of snow and salt. I usually just clean everything up with brake-clean let everything dry any spray them with Silicone spray before re-greasing the slides and sending it. Got a 96 Tacoma almost 300k with original boots. The silicone spray is what keeps them malleable.
Ordered some Carlson's. Never heard of them so hopefully not too bad. If they suck I will just return to amazon.
It's a new/used 2017 so figured they would be good to have incase OEM are ripped.
Carlson has been making brake parts since, maybe, the 70's ?? Never had a problem with Carlson brake parts or rebuild kits. Good product. You'll be happy with them.
Here is a shot of boots and bushings for a 2008 3/4 ton Chevy.
Mods, I used a screen shot from Rock Auto for the technical information on the difference between a boot and a bushing.

Too bad Raybestos is just a name now. They've been out of business for quite some time. Super Fund site now. Who knows where these parts are coming from. Friggin shame.
From a place that uses old worn out dies. When I got the last set of caliper pin rubber sleeves they grooves were not present and the bushing was oversized due to clearly worn/improper mold.
For what it's worth, never used Raybestos brake hardware. Normally Carlson hardware. I had no problems with their pads or shoes back in the day.
