I’d like to share my experience and likely may ruffle feathers. All the aftermarket lubricants will fail unless you regularly service them by removing the old stuff, cleaning, and replenishing with new lubricant within 2 years in rust belt area. I switched over to the AGS sil-glyde product for the caliper pins and after 3 years and 36K of not inspecting, the pin froze solid in the caliper for the ‘03 Corolla. Probably took me close to 3 hours of heating, soaking, rattling, and impacting that I finally freed the pin as it was destroyed regardless. No visually damaged boots and the solid pin with the non-rubber sleeve was the one that seized up. Upon further inspecting, the shaft looks more like orange peel so you can argue the base pin material corroded and the lubricant failed. I believe if you looked up the flat rate master on you tube, he expressed dissatisfaction with the Permetex purple ”decomposing” and turning gummy as I had. So now, I converted over to Toyotas supposedly factory rubber pinkish grease p/n 08887-01206 and see if any improvement. I serviced the caliper pins on my ‘15 Toyota Sienna that has never been serviced nor driven in the snow/salt water after 7 years and 50k, the pins are beautiful and free with no issues with the factory lubricant! Strange the color was more amber/tan/brown so I give up.
What I will say is only clean the pins with solvent clean and wipe, and NOT use a dremel, wire brush, sand paper, abrasive pads, grind wheels, etc. etc. because this will scratch the factory anodize or chromate dip in the pins and basically you just bought the farm like I did. I’m betting that‘s the culprit in my example frustration. Either replace pins if too corroded or aggressively clean as mentioned and shorten service intervals to 1 year. Choose whatever brand AGS, Super Lube, Permetex, Mission Automotive, 3M, factory…but properly service every 2 years minimum.
