2. Symptoms that indicate potential brake problems: Vehicle pulls to the side when braking, noise when braking, increased brake pedal travel, pedal force pulsation, brake fluid leaks, especially along the side of the tires.
Disc brakes
3. Disc brakes use two brake pads, one outer and one inner.
4. Measure the thickness of the pads: if the thickness of the friction layer is less than the allowable one, replace the pad.
Note: The thickness of the friction layer includes the thickness of the metal plate.
5. Measure the thickness of the brake discs with a micrometer. If the thickness of the disc is less than acceptable, replace the disc (see chapter 9). Replacing the disk is also carried out in case of cracking, the presence of overheating zones and other damage (see chapter 9).
6. Before installing the wheels, check the condition of the brake hoses and the absence of harmful contacts.
Drum brakes
7. Dismantling procedure is described in Chapter 9.
8. Attention: Brake wear products contain asbestos: do not blow the drum with air, do not use oily solvents for washing, use a special cleaning fluid.
9. Examine a condition of a frictional layer of a block. If the surface is greasy, replace the block. If the thickness of the friction layer is less than 1.6 mm, replace the pad (always change both!).
10. Inspect the condition of the return and retaining springs, recirculation mechanism.
11. Examine the brake cylinder and a condition of anthers. If there are brake fluid leaks, replace the brake cylinder (see chapter 9).
12. Inspect the condition of the brake drum, see details Chapter 9.
13. The control of the operation of the brake booster and parking brake is described in detail in Chapter 9.
