Rep Power: 273 high pitch sound
Hi,
I need some diagnostic.
My 2002 Civic at 70k Km produces high pitch sound, somewhere in the rear, when I apply the break.
It happens in slow speed (while parking). It happens all the time, even when the car has been driven for hours and heated up.
What can it be? where should I check for problem?
thanks!

Rep Power: 295 huummm..... sounds like the rear brakes need new shoes. I would say 70k on the stock brake is pretty good, if you haven't changed them yet. I also had a problem with this once on an older civic of mine, it ended up just being a massive amount of brake dust built up in the drum.

Hi,
To give more detail, the high pitch sound ONLY happen when I RELEASE the break petal after a firm step-on. It actually happens at any speed.
So what diagnostic would you guys come up?
thanks!

Rep Power: 264 are you positive its coming from the back and not the pedal itself....might be squeaky....there was a problem with the sensor attached to the pedal that if you turned it like a quarter turn itd stop clicking i think.....

What I don't understand is that why the sound comes only when I RELEASE the petal.

Generally rear shoes don't go out that early, but perhaps if you do mostly city driving they would be used faster. Or if you have a sticking e-brake line. In any case you will have to check the rear brakes out, probably clean them off with some brake cleaner. While you have it apart, you should just change the brake shoes, they aren't that expensive. You could resurface the drum, but if the surface is not correct, you will hear some sort of cyclic noise. It is generally pretty cheap to get them resurface, I think I paid $10 per drum last time I had it done, but if are not rearing the cyclic sound, I wouldn't worry about it.

It won't make the sound when you press on the brakes because it is pressed to hard agianst the drum surface, but when you let off the brakes it will have just the right distance to make this sound. Then as you drive more the sound usually goes away. This is the first indicator that your brakes are going.
