Does it turn freely with the caliper removed? if not, check the bearings or hub assembly. You only replaced one caliper? If one's bad, the other isn't far behind.
Frozen brake caliper
The brakes may make a clicking noise if the caliper is going bad. I just changed the brakes and the rotors and discovered my car was making a clicking noise. The garage I took it to replaced the caliper, so now it doesn't make the noise anymore.
Rotors out of round?

Disc brakes are supposed to drag on the rotors, if you think they are too tight you will have to replace the calipers. The caliper slides may need cleaning and new hardware to allow the calipers to move freely.
If it's only brake pads $40-60. If rotors have to be replaced too + $20-50 per rotor + labor. If calipers have to be replaced too, it's + ~$150 per caliper.

Vibration when applying brakes is most likely warped rotors. Another cause could be loose caliper bolts.
Check to see if the brake caliper pins are stuck or stiff. Also, if the park brake is part of the caliper assambly it may be stuck. I've seen this on rear disk Grand Prixs and Luminas.
It must be the rear brakes at fault.
Your brake rotors are warped and need replaced/resurfaced.
There are a couple of possibilities. One is lack of lubrication of brake system moving and/or contact points such as between back of pads and caliper housing and/or piston. Another could be that, the rotors/discs are warped/distorted and need to be machined or more preferably, replaced. If you replaced the front brakes (example) and you still have a squeal, it's possible it may be coming from the rear brakes.
