Customer Question
Hello, on my 2014 Mazda...
Hello, on my 2014 Mazda 6 GT, I just replaced my rotors and pads with new ones on the front. It was working fine for a day or 2 but this morning it is making a groaning sound at slow speed. As I de-accerlate it will make the sound at the same time feel like it’s not stopping the car, like it will slip for half a second. I feel like if I slam the brakes it will stop, but maybe not fast enough if that makes sense.

Hello, I'm Brandon - Mazda tech.

What kind of brake pads and rotors did you use? Autozone?

Also have you replaced the brake fluid in the past?

Typically I tried not used aftermarket brake pad because you won't know if they are hard or soft brake pad.

There are various types of brake noise and many different conditions that can cause noise. Frictional co-efficient between brake pads and rotors varies depending on pad material, temperature, humidity, braking force, etc. During braking, the brake pads are pressed with great force against the brake rotor. This generates friction to bring the vehicle to a stop.

If the brake pads are of a soft compound, a larger amount of brake dust will appear on the wheels and the pads will wear more rapidly, but there will be less chance of brake noise.

If the brake pads are of a hard compound (as used in high-performance applications), less brake dust will appear, the pads will last longer, and braking performance will be improved. However, the drawback is that brake noise can occur more easily than with softer compounds.

Finding a balanced compound with the qualities of both hard and soft compounds is difficult.

You can apply some CRC Disc Brake Quiet to the pad backing plates and take a 80 grid sand paper and sand down the brake pads surface. These method will help reduce the noise.

Do not use grinding wheels or air power tools.

This is why we stay with OE brake pad or Akebono premium brake pad

Please rate me positive, thank you!
