How to Apply Disc Brake Quiet to Brake Pads

Squealing brake pads are often believed to be symptomatic of failing or worn brakes. Unfortunately, if precautions are not taken, a new set of brakes can make the same annoying squeal. The squeal that brakes make is often caused by vibration between the metal backing of the brake pads and the metal brake caliper when pressure is applied to the brake. A simple application of "disc brake quiet" creates a barrier between the two metal surfaces similar to that of a rubber gasket. Without the pad and the caliper rubbing together, most often squealing brakes that aren't worn out are completely silenced.

Step 1

Lay the brake pads on a flat surface with the metal side up. You want to do this on a surface that can be sprayed upon and dirtied, in a well ventilated area.

Step 2

Put on rubber or latex gloves to protect your hands from the disc brake quiet spray. It is an irritant and is very sticky.

Step 3

Shake the can of disc brake quiet for several seconds, then remove the cap.

Step 4

Spray the metal surface of each brake pad evenly and in a sweeping motion until coated with a thin layer. Keep a clearance of about 12 inches between the pads and the spray nozzle when spraying.

Allow the brake pads to dry for at least 30 minutes, preferably in a warm place or in direct sunlight. This will ensure maximum adhesion of the disc brake quiet. Once 30 minutes has elapsed, the brake pads are ready to be installed on your vehicle.


  • Disc brake quiet, like paint, will permanently adhere to many surfaces. Try spraying your brake pads on a piece of scrap plywood, scrap paper or any other surface that will not be ruined by the spray.
  • You can remove disc brake quiet from some metal or smooth surfaces with the use of a degreaser or a brake cleaner product.
