I have a 99 Caravan, and I replace my pads (I used the cheapest pads I
could get from Murray's) & turned my disks (within specs) last year.
However, for the last 5 months, the brakes were squeeking and constantly
made the sound of grinding (near the end of my stop). During that time I
was constantly checking the surface of the disks and they were OK.

Finally, I got tied of it and replace the pads with ceramic pads &
replaced the disks with new ones. When replacing these, I noticed a small
indentation forming on the caliper bracket, but didn't give it too much
thought. I put the anit-squeek grease on the back of the pads and on the
caliper bracket where the pads & caliper contact.

After replacing the above, everything seemed great for about a week. Then
we notice squeeking and then once in a while at the end of a hard brake, a
grinding noise.

Now I'm thinking of replacing the calipers, guide pins, and posssibly the
caliper bracket (because of the indentation I saw). However, with the
brackets at $350 for two wheels, I'm begining to think not to do it.

Anyone with some ideas?
