Caliper Pin seized

okay.. well what the problem is on my rear brakes, one of the pin always get seized for some reason. The grease that I put in there almost turns into sand and seizes up the pin. I even replaced the pin and it did it again..

I'm not too sure but is there a way to clean the caliper bracket, where the pins are inserted into? or does the bracket need to be replaced?

What kind of grease are you using?

I used:

Permatex ultra slick synthetic brake lubricant
-40c to +240c (-40F to +400F)

It does say on the packaging to use on caliber pins, slides, clips, bushings, pistons, rubber sleeves, and seals.

So I'm not sure why it is doing that always. Once I put the pin back in, it almost like a vaccum seal. It compresses into the bracket and if I pull the pin out half way it automatically compresses in.

I really don't have a good explanation for why that's happening but I'm no brake specialist. I usually replace the pins & goop them up good.

I am not sure of the caliper bracket bore is all gunk'd up or something. We are allowed to use a degreaser to clean the bore out, right?

I'd say that would be a good idea.
