Zach,

I suggest you investigate the brake caliper itself. It sounds like it
is sticking that's why you can here the squealing after braking. The
caliper does not retract far enough and the pads are touching the
disc. This produces a squealing sound. Sometimes it will be worse on
cornering as the stress from a cornering wheel creates movement on the
disc.

This is common and appears after new pads have done some miles. When
the pads were fitted the pistons were pushed back road dust and all
instead of being cleaned with an air line or something similar. Over
time as the brakes are used, the dust builds up on the caliper piston
seals and causes the sticking. Also, renew the pad fixing kit (little
bars and split pins). As these too, corrode preventing movement of the
pads.
