I use HAWK performance ceramic pads and Raybestos PG plus rotors as well. I'm starting to get a vibration as well after only 15,000 miles. Not a happy camper!

Well pat does have a VERY GOOD point.

I did some adjustments today and my rears were out of adjustment significantly and still have 90% of the pad left. I'm guessing I was able to crank them about 1/8th to 1/4 of an inch so they are barely rubbing now.

It makes no sense to why they are not adjusting by themselves..I regularly do the old go in reverse at wot then brake, go forward and hit the brakes etc about 5 times at least once a month. I also use the Parking brake on at least a monthly basis.

I have no idea how long it took the rears to loose the adjustment, it could have been days or weeks, I'm going to check on them in a month to see whats up.

The thing is IIRC braking on these cars is around 70/30 so even if I was around 90/10 or something I see no reason for them to warp SO BAD, SO FAST. either way I'm sure having the rears adjusted properly and if they dont stay adjusted I'll order new adjusters...we'll see how long I can get on the ultra cheap rotors on there now.

The car stops amazing right now, easily as good as my 2000. I see no differences comparing them. I'm going to take it really easy on them, no grandma'ing the brakes, just quick stops.

I also need to cut back on the sudden 100+ to 75mph stops too.

Were the rear adjusters removed, cleaned and relubricated the last time the brakes were serviced?

Keep in mind that the cermaic pads won't pass the heat to the caliper and mounting hardware. All that heat that needs to be disappated now only has the rotor, hub,..
with the rotor bearing the brunt of the load. I researched before I switched over to ceramics that without good rotors I could expect to warp them regularly. On my truck I have raybestos drilled/slotted which have held up well, but on my wifes olds98 I have the two year warranty bendix from partsamerica; since she drives like an old lady I figured they'd be fine witht he added benefit of stopping quick when she really needs to.
