Chirping brake

I replaced front rotors and pads on my 2005 Dodge Caravan. They’re OK, but when I release the brake pedal the right front brake makes a " chirp " sound. Any thoughts on what this might be?

Likely either some missing or misinstalled anti-vibration hardware (normally harmless to operation, only annoying) and/or some lack of lubrication such as on caliper slides.

Are you sure it is from the front right? I recently had exactly this kind of chirp on one of my cars and it turned out that the braking material on one of my rear shoes (I have drums in the rear) had separated from the backing.

Had the same trouble with my car - disc brakes all around - with the right rear after I did a 4 wheel brake and rotor job. I then changed the brake fluid and the annoying ever so slight chirp went away.
