Default ARRRGGHH!!!! WHY ARE MY BRAKES STILL SQUEALING!?!?!?

Okay, so I replaced my wife's front brakes about a year and a half ago as well as the front rotors. I installed Akebono ceramic brake pads.

A couple of months later they started squealing so I took them off and greased them down. The squeal went away but came back about 1 month or so later.

I then took the pads off again and this time used Wurth 2000 to grease the backs of the pads. The squeak went away for a while then came back.

Fast forward to last weekend. I removed the pads again and greased them with anti-squeal grease that Autozone sells. I applied the grease on the back of all four pads, the caliper bolts, and the calipers. One week later and the wife is reporting that they are squealing again. WTH!!?!?!?

Do I need new calipers? Is there something better I can use to rid these brakes of the squeal? Help!!!

Did you lube all areas of the pad backing that touches metal?

Default Most likely your caliper pistons are not retracting properly because you calipers are all sludged up

What's your hydraulic system PM history? To eliminate the problem you need to overhaul all 4 calipers and replenish the fluid.

Default IMO, not necessary nor desirable, inasmuch as lube in these areas just attracts dirt and becomes...

grime.

Default I had the car to the stealer about a year ago to drain/refill the brake fluid but...

I'm not sure that they actually did it. The stealership here is very shady and as a result I don't go to them for **** anymore.

Default It does, but the grime will lubricate.. I've had to pry pads out of the carriers..

when not lubed.. They get grimed up whether you lube them or not here in New England.
