I used brake lube for the caliper slides on my Corolla as I recall. I think a little packet of brake grease came with the new pads. The service data I’m seeing for the 2001 Cav says to coat the inside of the caliper bushings with silicone grease. I see no explanation how to install or remove the dust boots. I presume if they don’t come off easily then they have to be destroyed during removal and new boots installed on re-installation.
On my Corolla the recommended caliper bushing lube is either a lithium soap base glycol grease, or a high temperature silicone grease (which seems to be the preferred grease now). I seem to recall that I had to rotate the dust boots as I installed them to get them to seat properly.
