i have checked the brake pads with a mechanic and they are OK. not worn out. i i looked at them and they looked OK indeed.
i asked the mechanic about the problem and he just said there is nothing to worry. the sound is because the car is old!

wtf (srr guys but i can't help it)
when i drove home i was going really slow (i was alone in the street at that time

) and i hit the break petal several times to research the sound location
a little more. It sounded coming from the break pedal towards the wheels. so basically the sound was coming from inside the car (driver side) towards outside of the car --> wheel location (driver side)!
When i completely stopped the car i hit the break pedal several times again and i didn't hear the sound. so only in motion the problem exist!
So i don't think is a WD40 problem because if it was, the problem would still exist even when i stop the car and try the break pedal!
Any other things you guys recommend to check? or maybe do?
Thanks in advance,
