Disturb the brakes manually.
Apply and release the brake a number of times. Shift into drive and reverse, and back between drive and reverse again to slightly move the vehicle back and forth. This may dislodge some of the rust.

This typically occurs due to rusting or ageing.
WD40 should not be put on your brakes since it can reduce friction where it is needed and even break down and damage brake components. While spraying WD40 may temporarily reduce a brake squeal or squeak, it could also cause the brakes not to function correctly when you need them most.
