That clicking noise you hear when you press and release the brake pedal is the "Shift Lock Solenoid" engaging and disengageing. The shift lock solenoid is located below the center console directly underneath the gear shift lever. That sound is normal.
that is the wheel getting ready to change gear
Brake booster problem?
No, on most newer cars you also have to press the brake pedal to shift out of Park.
when your brake pedal moves up and down when you press the pedal ,usually it is a warped brake rotor or a loose bearing on one or both brake rotors Warped front disk brake rotors.

Hardness in the brake pedal can because by low brake fluid. Air in the brake lines can also cause the pedal to push hard.
The power brake booster is failing.
press down firmly on the brake pedal and keep holding down the brake pedal
Make sure to press the brake before you take a break.
The 2001 Escape, with the gear shifter on the steering column, has an interlock solenoid located by the shifter assembly. The purpose is to lock the shifter in PARK until you depress the brake pedal. This is to prevent "sudden acceleration" where you engage the transmission with the brake off and the car shoots forward or backward. When you press the brake pedal a switch is closed that turns on the break lights and activates the solenoid, generating a magnetic field that withdraws the interlock pin, allowing you to move the shifter out of Park and into Drive or Reverse. The solenoid can make a clicking noise. We never noticed the clicking sound in our 2001 Escape until this mechanism had begun to fail, locking the shifter in Park regardless of the position of the brake pedal.
you probally need to replace the bulbs
