Found a cheap fix for a stuck brake caliper slide pin
My 2012 Honda Civic had a dragging rear brake last month and the shop wanted $300 for a new caliper. I pulled the slide pin, cleaned off the crusty old grease with a wire brush, and put on some $5 silicone lube. Has anyone else saved a caliper by just cleaning the pins instead of buying a whole new assembly?

Respectfully, I've been down that road and it's not always that simple. The pin itself might be fine but the bore it slides into can get corroded or egg-shaped over time (especially on Hondas), which means even new grease won't stop it from binding. I've had a few calipers where cleaning the pin did nothing because the rubber boot was torn and letting moisture in, or the piston itself was starting to stick. So sometimes $300 for a loaded caliper with new hardware and a fresh rubber boot is the real cheap fix versus chasing a dragging brake for six months.

You said "the bore it slides into can get corroded," but I've also seen people overlook the caliper bracket itself being slightly bent from a previous brake job, which no amount of pin cleaning will fix.
