How Do You Make Brakes Stop Squealing

How do you make brakes stop squealing? Consider the causes. The reasons brakes squeal is all related to movement of the brake pads. The scoring or grooving of the rotor usually starts the squealing by causing the brake pads to shutter in their mounting points.

Many items have been made to prevent this situation. Most cars come with some form of silencer, such as springs that put tension on the pad against its mounting point.

Shims come standard with many of the pads sold today. These shims resemble the shape of the pad and are meant to attach to the back of the brake. The shim has a rubbery side with adhesive. The shims are simply glued to the rear of the pad.

Another method of stopping a brake squeal is using a liquid called "Stop Squeak." The new pads are laid out face down and the liquid is applied to the back of the pad. It takes about fifteen minutes for the liquid to start to cure. Once it begins to cure, it makes a rubbery backing on the pads that absorbs the vibration.

To apply any of these methods the following tools will be needed:

  • Floor jack
  • Jack stands
  • Lug wrench
  • 3/8-inch drive ratchet
  • Set of 3/8-inch drive sockets
  • Set of wrenches
  • Bottle of stop squeak or other vibration stopping item

Raise and support the vehicle on jack stands. Remove the tire/wheel assembly. Remove the two bolts securing the brake caliper to the mounting bracket. Lift the caliper off the mounting bracket.

Remove the brake pads and lay them face down on a clean surface. Apply the solution to the rear of the pads in two wide lines. Allow the material to cure for fifteen to twenty minutes. Install the brake pads and the caliper. Install the two caliper-to-mounting bracket bolts and tighten.

Before you drive off, make sure the vehicle is in park or, in the case of a manual transmission, make sure it is in neutral with the parking brake on. Press the brake pedal three or four times to make sure the brakes are "pumped up." If the brakes are not pumped up and you try to drive the vehicle,  you will not have any brakes until they pump up.
