Semi Truck Brake Lubes

Having extra lube like Permatex® 85188 is a good thing to have so you can lube the caliper slide pins any time you change the brakes (just pull the slide pin out of the rubber boots/guide bushing, put a good coat of lube on the pin and reinsert, don't be afraid:). Also any moving or contact spots. You should keep some at all times if you are a casual DIY'er.
