I checked and the pads have plenty of material left and I lubed the slides and all the e-brake hardware, springs hinge, etc... To no avail except after i backed up and slammed on the brakes it was quiet for a while but not long. The squeel goes away when i touch the brakes at all though. Any ideas as to what else it could be its a 1997 with about 112,000 miles on it.
squeeling from rear wheels

Her are a few questions, Are the pads the original ones or has someone replaced them, Also are they semi mettalic or ceramic, and when you lubed everything did you also lube the back of the pad, and did you rough the pads up on the concrete? All questions I would need answered first. some cheap semi metallic pads will always squeak no matter what.
There ceramic, yes i did the back of the pads they have a rubberlike pad on the backing so i did not rough it up before lubing it. Though the piston did cut through a circle on all 4 wheels. Lubing it gets rid of the squeel when stopping for a while but this squeel when driving is within a few weeks.
Ok i thought you took it apart to lube the old pads and any time I do this I rub the pad material [not the backing plate] on the pavement to rough up the surface a little. It sounds like you may have a lubricant issue. At work I only use synthetic brake lube. because the rest of the world is picky and one little squeak will bring'em back. Try this and the little shims that go between the pad and the caliper bracket may need to be replaced and clean and grease under them. Use a wire brush to clean old dust off. Also what brand are these pads ? 
Im not sure what brand they are the better pads from napa but cant remenber the brand. I greased everything with synthetic universal/chassis grease after cleaning it off. Is it possible it could be the rear hubs in need of replacement?
Do you mean wheel bearings? If so you would have a howlin or a groan, and by turning the car while driving it you could take pressure off of the bearing and increase the pressure on the other side of the vehicle, in turn makin said moanin bearing become quiet or louder. When you turn left the weight of the car is on the right wheels and when you turn right it is on the left. So if you turn left and the noise increases you would have a bad right bearing or vise versa. Or you could just have bad junky pads. I prefer wagner thermo quiets or wagner ceramics. Also you said you are using chassis grease, though synthetic it can not handle the heat of a brake system you need brake lube it will not melt away in 2 weeks, or a year. Also were the rotors turned they could be glazed.

1bad4.6 is all over this, only question I had is, are you running ceramics on cheap rotors? or rotors designed for the extra heat. I've never run ceramics on anything in the back, just isn't enough pressure exerted IMO Also did you sand and lube the slides so they slide free?
A whole lot of the newer cars are ceramic only such as an monte carlo from 2000 up, struck me as odd also but they do create less dust and last longer. I think that since over the years weight distrubition and the advent of disc at all 4 corners has come along that the old law of 60/40 front rear has long been alleviated and it is more 50/50. Also on newer chevy trucks with only 40,000 miles I've been replacing all 4 pads and rotors. That build quality is sad to me. The rotors are so close to throw away spec on the rear [the hatted ones] that when they are new you couldnt turn them. thats G.M.'s throw away spec. Wich to me is ridicoulous. I also run ceramic on everything I own. front and rear.
