What’s the school of thought here? I’ve been dealing with a seized brake piston (OSF) and also old stuck slider bolts.
I’ve managed to free off the piston and I’ve cleaned and lubed the slider bolts with some high temp grease. It didn’t look like the slider bolts had had any grease on them and the rubber boots were in good nick.
I wondered if they were supposed to be dry??

Re: Calliper sliding bolts
Scratch that I’ll answer my own post. Silicon grease is supplied in the repair kit so my high temp grease should be fine for a while.

Re: Calliper sliding bolts
I have some experience from working with different brake calipers and sliding bolts. It seems that European cars mostly use ATE brakes and those are using sliding bolts made from stainless steel. Normally working good in salty winter roads, a long as the gaskets are ok.
But if looking at Asian cars, they often use Akebono brakes, using galvanized sliding bolts. Those, you normally have to remove every second year to clean up and use fresh grease again. The galvanization will also disapear, a change of sliding bolts is recommended.
According to one specialist in repairing Mazda, he told me to remove the sliding bolts every second year, then it will still not be any problem to get them out. Fill the hole for the sliding bolts with maximum amount of heat resistant grease! Really fill it, not any thin layer.
