Safety is one of the main advantages of a car. The car must not only accelerate quickly, stand firmly on the road, but also stop quickly. Disc brakes are now installed on all vehicles, proving their high reliability and efficiency.

Step 1
Despite their advantages, brake discs are more prone to wear than a brake drum. This is due to the fact that the disc is sensitive to beating and negative environmental influences. From this it follows that from time to time you will need to check the status of the disks.
Step 2
To check the disk, you need to do the following:
- raise the handbrake; - loosen the bolts of the front wheel; - use a jack to raise a part of the car; - remove the wheel; - while rotating the wheel, inspect the disc from all sides. If you notice significant seizures and cracks, then change the disc; - using a micrometer, measure the thickness of the brake disc. If at any point the thickness of the disc is equal to the minimum permissible thickness or even less - change the disc - check the runout of the disc. Position the gauge 5 mm from the outer edge of the disc and twist the disc. The maximum disc runout is 0.03 mm. If the runout is greater, then either replace the disc or grind - check the disc for cracks and other damage.
Step 3
The main problems with a brake disc are uneven disc thickness, roughness and disc curvature. You can replace discs with such defects, but you can also waste them without removing. This method is the most rational.
Step 4
Brakes don't have to be bad - it's life-threatening. Timely diagnosis is the best way to protect yourself and those around you.
