I thought brake grease on slide pins was a scam, then my pads wore uneven at 9,000 miles
A seasoned tech named Marco kept harping on cleaning and greasing caliper slide pins at every pad swap, and I figured it was just a way to pad the ticket. Last spring I did a quick pad slap on my own truck and skipped it, and by fall the inner pad was down to metal while the outer still had half its meat left. Pulled the pins out and they were dry and gummy, which is why the caliper was dragging and cooking one side. Now I keep a tube of silicone grease in the box and hit every pin I touch. Any of you run into a brand of grease that dries out faster than the rest?

Boy, you nailed it. The uneven wear is the tell every time. I got burned by the same thing years back on a car I thought I was saving time on, and the pins were so dry the caliper would not float at all. Here is what I want to know, when you pulled those pins, was the boot torn or did it still seal right? Because I have found that even good grease will not save you if moisture gets in past a cracked boot and turns everything to that sticky paste. And on your grease question, the cheap stuff in the little packets seems to harden up way faster than the tubes of silicone. Do you put anything on the pin ends where they sit in the bracket too, or just the shaft?
