I'm finally getting the rear brakes put together on my car. Got the lines put into the calipers, and looked up torque values for the caliper bolts. Of course, while doing that I noticed that the manual (Haynes) says to replace the caliper bolts with new ones. Verified it with the Volvo manual, then swore a lot, went inside and started looking online for bolts.

Before we get too far into this, I'm probably going to replace them with new bolts. Going against the manufacturer's recommendation scares me, especially with something as safety-related as brakes.

That being said, the purpose of this post is to try to understand just why it is that Volvo would recommend replacing them. They seem fairly heavy duty, and the 48ft-lb torque rating (if I remember correctly) seems like far too low to be a torque-to-yield value. Only thing I can some up with is that the new ones (like these: https://www.fcpeuro.com/products/volvo-brake-caliper-bolt-240-244-245-genuine-volvo-947328) seems to have a red spot that I'm guessing is some sort of high-temp thread locker. I feel like some high-temp loctite could replace that. Does that sound right? Am I missing something?
