Grinding Noise When Braking But Pads Are Fine

Using poor quality brake pads

Although the performance of the gasket is still good, if the product you are replacing is of poor quality, it will cause noise to appear. It would help if you did not try to save money on essential car details because that’s the best way for you to ensure yourself and those around you.

When a poor-quality brake pad is put in and used, it will reduce the brake system’s performance.

In addition, these problems are also in their shortcomings. In particular, you will likely find metal fragments in the gasket material in the gasket. This debris will rub against the rotor and cause severe damage.

In addition, when you have selected good brake pads and still have noise, you will need to check their cause. One common cause of a blown head gasket, so knowing how to fix a blown head gasket is necessary. At this point, you need to repair or replace the brake pad with a new one.

Shims worn

Brake pads that are not replaced for a long time will corrode because they are in direct contact with the rotor or another metal part on the brake system.

From there, the grinding sound will appear when the metals collide with each other. At this point, you need to replace the shims to ensure the vehicle’s performance.

Debris stuck in brake

Debris trapped in the brake includes debris, rocks, gravel. When inside the brake system, the small one will be between the rotor and the caliper. Grinding noise will appear from there, and the vibration is the next phenomenon you may encounter.

In addition, when the amount of debris is high, you will hear the noise even when you do not apply the brake. After some time, the rotor will be at risk of failure due to too much debris inside. At that time, reduced engine performance is inevitable for your vehicle.

Less use of cars

Typically, a set of brake pads will be practical for 30000 to 70000 miles. But when you don’t use the car for too long, rust will appear and stick to the brake pads.

As a result, the surface of the brake pads and rotor will not be as smooth as the original due to impact rust. At this point, you will hear a grinding noise.

Worn brake rotor

A poor-quality brake rotor is when it appears warped or cracked. When it does, it will make many strange sounds. At the same time, the warped propeller will also make a creaking sound.

Also, when your rotor is too worn, it will create a lot of vibration from the brake system. These vibrations will appear when you apply the brake.

Do not lubricate the brake unit

When you install or replace brake pads, the back of the brake pads will need to be lightly lubricated using a brake caliper lubricant.

When you forget or intentionally skip this step, the metal gasket will become dry. From there, the metal piece and the piston caliper will combine and create a grinding noise when you step on the brake.

Caliper bolt

The caliper bolts need to be lubricated consistently and evenly, or they will not function properly. When the bolts are dry, it will make a squeak when you step on the brake. Over time, the bolts may be due to the lubricant setting.

Faulty wheel bearings

As for the cause of the wheel bearing failure, this is the least likely scenario. However, it would help if you did not ignore this case. Because when the wheel bearing fails, it will make a grinding sound from the wheel side, or you will feel the vibration from loud to quiet when you apply the brake.

Backing Plate Rubbing

According to the brake set structure, behind the brake rotor will be a pad. The purpose of the gasket is to protect the brake and rotor from road debris.

Sometimes, in some cases, some large foreign body can warp the pad. When it does, it will rub against the propeller and make a loud grinding noise when you drive. To fix this problem, you need to bend the pad back to its original position.
