Well today i was just moving my car to unblock my family car before they went off to work and me to school.
So i had the windows down and i put my car into drive and everything was perfect but when i reveresed it into my lil parking space i heard a noise coming from my back left tire area. Don't know if its rotors brakes or anything. Its liks squeaky like hmm nails on chalkboard kind of thing. Any ideas?
i really dont' know about maintenance just the usual stuff.
Please help i would like to get the problem solve!

 

By any chance did you just wash your car (or recently)?

Sometimes you'll get a bad grinding sound out of the brakes when they're freshly wet.

 

i belive that i was it on sunday. i think the noise was there for awhile i would always hear it when i cruise with the music down and its feeling really great outside. just when i hit reverse i heard something wierd.

 

did you check the rear brake pads?

 

This noise is pretty much normal after the rotors get wet due the pads rubbing on a thin rust layer...it usually goes away after 2-3 brake applications. If it doesn't, have the pad thickness checked to see if they are worn down to the point where the rivets underneath are hitting the rotors. If they are, you need a brake job......and maybe rotors..... immediately. The pad-wear screechers are supposed to audibly warn you of this but they don't always work right.
Another common brake noise on many Toyota-Lexus products is a clicking or tapping noise upon first shifting into reverse or any forward gear and pressing the brake pedal due to the brake pads or calipers shifting position slightly and hitting up against their stops. Again, this is pretty much normal and not indicative of a problem....it is simply the way the calipers are designed, although you usually don't hear it on a brand-new car...it usually takes a couple thousand miles to develop.
