In the customer complaints of brake pads. The most common problem is noise. There are many reasons that can cause noise. But Is usually caused by the following reasons.

2)Grind the edge of the pads, to make sure that the surface of the pads can touch the disc. Please remember to grind both of the up and down edge.
