Why does my car make a clunk noise when I release the brake?
Yes! All is well now. The clunk noise was the driver side control arm that extends forward from the spindle to the frame moving back and forth in the mount. I could see the arm moving but couldn’t tell if it was the bushing worn out or the mounting bolt until I had them out of the frame mount.
Why does my car make a noise when I put my foot on the brake?
Usually this is because the brake pad wear indicator is touching the rotor. If the wear indicator is touching the rotor, sometimes the noise disappears when you apply the brakes, and returns when your foot comes off the pedal. If you hear this type of noise when you’re not applying the brakes,…
What to do about clunking sound at back of car?
If you jack up the whole back end and put the car in neutral, you might be able to rotate the wheel on the other side and see if the noisy brake disk is warped, but I wouldn’t swear to it.

What should I do if my car makes a grinding noise when I brake?
