Not only are squeaky or grinding brakes loud and embarrassing, but they can also be dangerous. The noise is a clear indication that you need to adjust, clean or most likely replace your brakes. Jeep Cherokees are equipped with drum brakes in the rear instead of disc brakes. These type of brakes differ from disc brakes due to the use of brakes shoes instead of brake pads. Drum brakes have many components, which requires a little more patience and special tools when replacing the rear drum brake shoes.
