These are the culprits. I only did the fronts.
What you have to do is clean them up, lubricate them, and voila! No more squeal. I also cleaned/lubed the guide pins while I was there. Very gunky.
The area in Green is what I lubricated on the brake pad itself. I also lubricated that same area on the where the pad is held, on the pad guide. (shown by the red lines)
Try it, cost me 7$ for a packet of brake lube and can of brake cleaner. I just reversed out of my drive way without a sound.
For reference:

To make things easier for you here:
Front Brakes
Loosen and remove the bottom guide pin ...
... then rotate the caliper upwards
Remove the pads from the caliper mount
Compress the piston into the caliper
Lubricate the guide pin before installing it
Remove the cable bracket bolt then pull the bracket from the caliper
Remove the bottom caliper pin bolt ...
... then rotate the caliper upwards
Remove the pads from the mount
As an alternative, a pair of needle nose pliers can be used
Be sure to lubricate the guide pin before installing it
Front Brakes
- Raise and support the front of the vehicle, then remove the wheels.
- Remove the bottom guide pin from the caliper and swing the caliper cylinder body upward.
Loosen and remove the bottom guide pin ... ... then rotate the caliper upwards Remove the pads from the caliper mount- Remove the brake pad retainers and the pads.
- Compress the piston of the disc brake caliper.
- Install the brake pads and caliper assembly.
- Lubricate the guide pin. Tighten the guide pin to 16-23 ft. lbs. (22-31 Nm).
Compress the piston into the caliper Lubricate the guide pin before installing it- Install the wheels.
- Apply the brakes a few times to seat the pads. Check the master cylinder and add fluid if necessary. Bleed the brakes, if necessary.
- Raise and support the vehicle safely.
- Remove the rear wheels.
- Release the parking brake and remove the cable bracket bolt.
Remove the cable bracket bolt then pull the bracket from the caliper Remove the bottom caliper pin bolt ... ... then rotate the caliper upwards Remove the pads from the mount- Remove the bottom pin bolt and lift off the caliper body.
- Pull out the pad springs and then remove the pads and shims.
- Clean the piston end of the caliper body and the area around the pin holes. Be careful not to get oil on the rotor.
- Carefully turn the piston clockwise back into the caliper body (this can be done with a pair of needle nose pliers). Take care not to damage the piston boot.
- Coat the pad contact area on the mounting support with a silicone based grease.
As an alternative, a pair of needle nose pliers can be used Be sure to lubricate the guide pin before installing it- Install the pads, shims, and the pad springs. Always use new shims.
- Position the caliper body in the mounting support and tighten the pin bolt. Be sure to lubricate it first.
- Install the wheels and lower the vehicle.
- Apply the brakes a few times to seat the pads. Check the master cylinder and add fluid if necessary. Bleed the brakes, if necessary.
