The caliper pins on my front brakes were not bound up and the factory grease was not dried out.And this was almost 7 years from build date. I did use SYL-GLYDE silicone grease on the pins when doing the brakes.I mentioned not too long ago in another thread that I religiously high pressure spray down the brakes good at the car wash.Easy to spray thru the spokes.Just don't do it with hot rotors.I also put the wand thru the grille and spray the radiator,A/C condenser and surrounding area good, especially when the roads have been salted.
The front brakes are easy to do.Forget the dealer.And don't assume that they grease the pins when they service your car.And when retracting the caliper piston (with C-clamp or whatever) just open the bleeder screw and vent that old fluid.Then top off the brake reservoir or suction it out and fill it with new fluid.Or bleed the system which would be best.
