Hyundai accent 2005 when starting up the vechile and driving there is a constant ugly sound coming from the front passenger side wheel and when applying the brakes on there is a high pitch squeel

In your brake system when the squealers are touching the rotors they will make a squeal noise when your foot has not applied the brake pedal when you apply the brake pedal is squealing noise goes away from the squealer indicators on the brake pad so with that being said it sounds to me personally with my experience that you have like I said another questions a bad wheel bearing or your brake pads are so worn that they're metal-on-metal to the rotor in any more rotors are fairly cheap so turning rotors is a thing of the past cuz if you do turn the rotors more than likely in five to ten thousand Miles you're going to have them come back with brake pulsation so you want to replace your brake pads with rotors no matter what so you have two new surfaces together and when they heat up and and they're able to see right and then you have optimum breaking as long as you have good calipers show you won't know until you pull the wheel and look and you should have a bunch of brake dust on the wheel and you know it would probably pull to one way or the other wherever the worst break is if that's what it is they could be a wheel bearing too but wheel bearing isn't going to have a squealing noise when you apply the brake but you could have two different things going on as well so the squeal noise could just be glazed up rotors and then the ugly noise could be the actual wheel bearing you know what I mean so until until you actually go out and drive it with a mechanic and swerved back and forth at 25 where there's no cars or any other instructions and the noise he determines is a wheel bearing which would be a growling noise and it would be faster the faster the vehicle goes and it would be louder one direction in the other with the weight of the vehicle shifting on that bearing and not if you follow me good luck to him

That screeching sound is a warning that your brake pads are worn down to the point where they should be immediately replaced. If you do not replace the pads, you'll score the rotor and incur an additional expense. Remember to replace the brake pads on both sides, i.e., driver and passenger side.
