My Brakes Squeal After Changing the Brake Pads in a Ford Ranger

The Ford Ranger has been around since 1983; and since that time, its solid reliability record and affordable price have made it a popular small pickup. As with all vehicles, when work is done on the brake system, the components may take some time to adjust to each other. One obvious symptom that is sometimes apparent is break squeal after a pad change. While irritating, this problem is usually not critical. Knowing the possible causes of brake squeal can help in addressing this issue and quieting the brakes.

Instructions

    1

    Allow the new pads time to wear in. Hard ceramic pads will take more time than soft organic fiber pads, but normally 300 to 400 miles of city driving should give the pads and discs time to break in. This distance could be double if only the pads were changed and not the discs. Once this process is complete, the squeal should be reduced or eliminated.

    2

    Add soft shims on the backs of the pads. These will dampen pad vibrations and reduce noise. If the newly installed pads were inexpensive, then they probably did not come with shims, and even if shims were included, they are likely not the best quality. Purchase proper noise dampening shims from your local auto parts store and install them. Sometimes applying anti-seize compound to the back of the brake pad where it contacts the piston will also help to reduce squeal.

    Disassemble the brakes and double-check all components. Be sure the slider pins are well lubricated and that the caliper moves freely. A partially seized caliper can cause squealing. Check the piston surface and be sure it is evenly contacting the back of the brake pad. Check the surface of the brake pads for any dust or other contamination, and check the surface of the discs for scoring or other damage. Clean and replace parts as necessary.

    Remove the brake pads and have the lining edges chamfered at a reputable brake shop. Chamfering the edges has been shown to reduce brake noise, especially with harder pad materials.
