Anti-seize on a slider pin?

Question

Is there any circumstance in which it would be acceptable to put anti-seize on a slider pin (for a brake caliper)?

A mechanic wrote this to me:

"When slider pins are serviced, they are removed from the mounting bracket, buffed on a wire wheel and lubricated with anti-seize or a synthetic brake lubricant. Both options are acceptable (contrary to your Google search) and provided by Napa."

As the mechanic says, I've already done research on the topic. I could tell you what I found, but I don't want to do anything to compromise the neutrality of the answers.

I can at least show you what research I have done in order to make sure this question wasn't a duplicate:

• What type of Brake Lube to use (gives one suggestion for a product to use on slider pins, but doesn't address the question of whether or not anti-seize would be acceptable).
• What brake components need to be lubricated? (has anti-seize mentioned in two of the answers, but neither mention refers specifically to using it on the guide pins).
• Replaced brake pads - one pad was full, the other was gone. Brakes now very hot after driving (anti-seize is mentioned in association with guide pins in one of the answer, but there's a lack of details and this answer has a net score of 10 lower than the top-voted answer, so it seems relatively poorly received).
• Sounds like brake disc is making contact with pad shims (for completeness, I'm listing here the last thread from, the 6 results in my search for "anti-seize sliding pin" which might be interpreted by some as being relevant, but it seems a lot less related than the previous three that I listed here).
• Squealing Brakes (2012 Chevy Cruze RS) (searching "anti-seize guide pin" gave me two results, one that I already listed above, and this one, which I think is fair to say is not very relevant).

Answer 1

What your mechanic told you seems to be spot on and good advice.

There is nothing wrong with putting anti-seize on the guide pins of a brake caliper. The idea is to ensure the caliper slides easily/freely without binding. Anti-seize should provide that without compromise. The only thing you have to look out for is to ensure you do not get it onto the rotor or friction surface of the pad. Either would compromise the stopping ability of the brakes. If you've ever dealt with anti-seize before, you'll know it tends to get everywhere. Care with handling fasteners which have been coated with anti-seize should be at the top of your list. If any does get onto either bit (rotor or pad), ensure you clean them with brake cleaner and a clean cloth prior to final installation.
