Why are my brakes squeaking/grinding on Audi S3?

If you hear brakes squeaking/grinding on Audi S3 whilst driving, it is most likely an underlying issue with the brake pads.

Below, we will highlight the common reasons for brakes squeaking/grinding on a Audi S3, and we will explain the steps to rectify these issues.

Brake Pad Wear:

Worn out brake pads on a Audi S3 is one main reason brakes make a squeaking or grinding noise.

Prolonged use will cause the friction material on the brake pads to wear down, which will cause squeaking. In more serious cases, grinding noises will be heard when you apply the brakes.

It is necessary to maintain regular brake pad inspections and replace the brake pads when needed to prevent this issue.

Brake Dust Accumulation:

A byproduct of brake pad wear is brake dust, which can pile up on the various brake components, including the brake pads and discs. Too much brake dust can form a gritty surface, causing squeaking noises.

Make sure to regularly clean the various brake components to help rectify this issue.

Disc Issues:

Brakes squeaking/grinding on a Audi S3 can be a result of unevenly worn, damaged or warped brake discs. Disc problems can usually be felt through the brake pedal as well. To rectify this issue, it is necessary to resurface or replace the discs. Seek help from a qualified technician who can diagnose and fix this issue.

Brake Caliper Problems:

Brakes squeaking/grinding on Audi S3 can be due to malfunctioning or stuck brake calipers, which can cause uneven brake pad wear.

To rectify this issue, it is necessary to inspect the calipers for proper function. Consult a qualified technician who can diagnose and fix this issue.

Low-Quality or Contaminated Brake Pads:

Poor quality or contaminated brake pads can lead to squeaky or grinding noises. Consider investing in high quality OEM (Original Equipment Manufacturer) or premium brake pads, and make sure they are free of contaminants during the installation process.

Weather Conditions and moisture:

Brakes squeaking/grinding on Audi S3 can be due to water or moisture on the brake components. This normally occurs after rain or in humid temperatures.

In this case, the squeaking and grinding noises normally disappear as the brakes heat up and dry out. However, if the noise continues, then it is necessary to inspect the brake system for any underlying issues.

Lack of Lubrication:

Brakes squeaking/grinding on Audi S3 can be due to
lack of lubrication. Make sure the correct recommended lubricant is used during brake service.

Foreign Objects or Debris:

Brakes squeaking/grinding on Audi S3 can be due to
debris or foreign objects being stuck in the brake components. Thoroughly inspecting and cleaning the brake system can help fix this issue.
