Tips Getting Rid Of Brake Noise

DO NOT DELETE

There is nothing as annoying as constant brake noise. Here are a few tips to help you get rid of such noises.

Ensure Proper Lubrication

The braking system involves multiple moving parts. Braking also requires friction between different materials. The more work the moving parts have to do, the noisier they might get. Lubrication is one way of ensuring ease of movement and quieting the brake. Lubrication will also keep rust at bay, which is also good since rusty brake calipers can be quite noisy. Consult your auto repair shop for recommendations on the best brake lubricants.

Clean the Brake Drums

Your car's brake can also be noisy if they are dirty. Debris accumulation on the drums increases friction, and more friction means more noise. Rust or road dust are some of the worst culprits. A wire brush can help you get rid of such debris; sanding can also achieve the same purpose.  In many cases, you need to combine the cleaning with lubrication for the best results.

Dampen the Brake Pads

Brake pads that don't fit properly in the calipers make noise due to their vibrations. There are different methods for silencing such brakes. For example, some brake pads come with tabs that can be bent for a better fit. Some also come with clips or anti-rattle springs that absorb some of the noise. All these will only help if they are properly installed.

There are also different materials you can install to absorb some of the shocks from the brake vibrations. For example, there are insulator shims that you can install on the back of the pads to dampen the inherent vibrations of the pads.

Resurface the Rotors

Brake rotors are quiet if they are smooth and flat. Unfortunately, brake rotors lose some of their smoothness each time you brake. Over time, the accumulated wear and tear leads to uneven surfaces that increase brake vibrations, and hence the noise. Fortunately, you don't have to replace the rotors if they are still in good condition (other than the uneven surfaces). You can have the rotors resurfaced to regain their original smoothness.

Replace the Relevant Parts

Lastly, serious damage or wear and tear of various brake parts can also make noise. The brake pads, slides, and bushings are some of the parts you may need to replace. Note that some brake materials are inherently noisier than others. Thus, if you want quiet brakes, you may have to replace the existing ones even if they are not damaged or worn out.
