A loose belt is the most likely culprit, when you press on the gas all of a sudden the engine will respond quickly but a belt driven component like the alternator will give resistance thus causing the squeal.
A bad throw out bearing will make noise when the clutch pedal is pushed down.
Does the noise happen all the time you push on the gas pedal or only at certain speeds?
Start by checking the fuel pressure.
Breaks will often squeak when they are wet, such as after a heavy rain, on a humid day, or on a foggy morning. The water prevents the pads from properly grabbing the rotors. This causes the squealing noise.
A vibrating brake pedal is an indication of a warped rotor. Noise is common to disk brakes but depending on the noise it can mean that the brake pads are worn out and you are due for a brake job.
When the turbo winds up it can make a whistling sound when a driver steps on the pedal. A loose part can also cause a rattling sound when the pedal is used.
could be the throw out bearing
It will be noisy, squeaking or squealing coming from the trans, and you may feel roughness or vibration through the clutch pedal when holding it in, it may also give you a little extra resistance when pushed.
The pedal in the car you push to go faster is the accelerator pedal.
Do you mean when you push the pedal " hard " you hear noise..........if so could be the ABS..........if not, then please have your brakes checked for safety.
Your brake booster is malfunctioning
A short in the brake light circuit.
