When you experience any kind of brake noise, you can safely assume there is an issue. The noise may or may not be a sign of a serious brake issue, however, whether the issue is minor or severe, it still needs attention and investigation. When you hear brake noise while your car is in reverse, this can be a sign that there is one of a few possible issues happening.
A common noise heard from brakes while a vehicle is in reverse is clicking. Most often, this clicking noise can be attributed to the brake pads moving or shifting into the new line of travel. A repeated noise, however, is likely created by too much movement between the surfaces of the pad abutments and caliper. This noise does not necessarily mean there is a dangerous issue going on. You can minimize and even eliminate this clicking noise by applying a disk brake caliper grease. The grease should lubricate the brakes and help eliminate the noise. After applying the grease, you should check further if you still hear it at the same frequency or level as before.
This clicking can also be made by a lack of anti-rattle clips. During brake change these clips were removed and possibly never replaced, particularly if you carried out your own brake change and didn’t have a replacement set. Simply get some new clips and put them back on your brakes to solve this issue.
SQUEALING – WEAR TABS
Squealing and squeaking while driving in reverse can be caused by several different issues, so after checking one issue you should research more if the sound still persists.
