As a result of the friction of the pads, the brake discs are worn out and a lip is formed on them. This is a common cause of squeaking brakes. Therefore, when a wear appears, the disks must be ground, removing the edge. This is possible in a garage environment with a minimum of tools.

Disc turning process
To sharpen the discs, it is necessary to jack up the drive axle of the car to raise the wheels above the ground. For safety, it is worth placing wooden blocks or other supports to securely fix it. After this, use a wheel wrench to remove the wheels.
In the car, turn off the traction control system and start the engine. Then we engage 5th gear to ensure rapid rotation of the discs without wheels.
After this, using a grinder with a flap wheel installed, you need to grind off the edge on the brake discs. Since they rotate, the metal is removed evenly. The edge is ground off from the front and back sides of the disc. Grinding in this way takes 2 minutes, and everything turns out smooth and neat.

This method can be used to sharpen discs only on the drive axle of a car. The remaining two will have to be temporarily rearranged on it, and also processed with a grinder. In the case of an all-wheel drive vehicle, you can immediately lift the whole thing and process all the disks without rearranging.
