Why Do Brakes Squeal And How To Fix Them

Noisy brakes are not only annoying, they can also be a sign of ineffective stopping power which is

dangerous for you and others on the road. It is important to note that not all noise made by your brakes means they are failing, from time to time your breaks will make some noise.

What Makes Brakes Squeal?

Denver brake repair experts say, modern braking systems use a cast-iron disc that is squeezed between two brake pads which are lined with friction material. The disc, pads and caliper can at times begin to vibrate which causes the system to give off a high frequency noise. The noise that is produced depends on how hard you press down on the pedal. Some brake systems are more prone to squealing than others, so it is important to research the brakes you are recommended before having them installed. If you find your brakes to be too noisy, or suspect a problem with your brakes, bring your vehicle into a mechanic. Mechanics can dampen the noise, change the resonant frequency of the arrangement, or replace your brakes.

The Fix(es)

• Check for loose parts. 
• Replace shims or clips that are loose or damaged.
• Try applying a dampening paste. 
• Replace worn brake pads. 
• Change out the brake pad to one made with a different material. 
• Check the brake rotor or drum for scoring and other wear. 
• Have the rotors resurfaced if their wear is not too deep.
• Replace the rotors or drums.

Why Do New Brakes Squeal?

 If your brake pads and rotors have recently installed, but are still making that awful squealing sound when your brake you're not alone. Replacing your old noisy, worn brakes just to find that your new brakes squeal as well can be one of the most frustrating auto issues you'll encounter, so what's causing it? New pads and rotors vibrate together just like older brakes. Your new rotor is wedged in between the new brake pads causing a vibration motion which results that annoying squeal.

The new brake noise will not last forever. The sound will reduce after about 275 miles and by about 800 miles you should rarely hear any brake squeal at all. During all these miles your brake setup will settle into itself and work in a more efficient manner reducing the vibrations creating the noise. While you are waiting to rack up those 800 miles, try applying a dampening paste to the brakes.
