Rubber squeaking sound when breaking

98 Windstar 251K

I recently replaced wheel bearing on Front driver side, the noise was present before replacement.

When I step on the brakes I hear a squeaking sound like a rubber bushing squeaking, also it changes as the wheels turn. I have also cleaned the brake rotor but have not had it turned for being warped, could this be the piston seal in the caliper or pins.

Any suggestions greatly appreciated.

It might be the anti-sway bushings.
