rear calipers
I'm inspecting brakes and don't understand what I found on rear caliper. When removing the retaining bolt, the threaded (inside) pin rotates with the bolt. I had to hold the pin with pliers to finish removing the retaining bolt. Once apart, the pin could be pulled out of the caliper. It appeared to have some sort of lubricant on it.
Is something wrong? Shoud I relubricate the pin? How to you torque the bolt on reassembly without the pin rotating with the bolt?
Thanks!!

What you have found is the caliper slide pin. The bolt on top is loosened by putting a wrench on the slide pin just above the boot. When reassembling you will want to put some blue Loctite on the threads of the bolt and if the pin appears somewhat dry you will want to very lightly add some lubricant. They sell small packets of this lube at most auto supply stores. Put only a small amount on the slide. When re-tightening the bolt, torque to 23 ft/lbs as per GM Service Manual. You don't really need to use a torque wrench for this. If the boot is torn or missing, it should be replaced. Also, the pin should slide very smoothly.

clean the old dirty grease off the slide pim, clean it with some brake cleaner, re grease it and re-insert it...
then torque as per above posts.
You can use some silicone grease or brake pad grease... most auto parts stores sell a single use packet
(about half the size of a single use ketchup packet at fast food outlets) forunder $1.
