i have a '95 disco with new front rotors and pads. these were put on by an authorized lr dealer. i have noticed a squeeking on the left side, especially loud when the truck is really hot. i took off the wheel and noticed that the caliper seems to be too close to the rotor. it looks like the caliper pistons are not retreating back into their homes... :-)
is there a lubricant that is safe to apply to the pistons?
i already tried gunk brake cleaner (nasty stuff) which worked for about half a day.

thanks,
kevin

forgot to mention that the inside of the rotor (closost to the hub) has a bit more wear than the outside of the rotor, due to the excessive drag.

You can get it any almost any parts store.

If they will not retreat into their bores, I´m afraid they won´t respond too well on lubricating the piston. Try it, and if it does not work (never worked on any car for me), you're into a caliper overhaul (i.e. new pistons and seals). You´ll do it in a saturday. Chk my site for details.
Hope this helps!
