Drum brake is one of the types of braking system, which consists of a rotating drum and braking is achieved by pressing the brake shoes to the drum. Brake pads consist of metallic components that are moon-shaped, to surface of which the shoes, made on the basis of the asbestos, are attached. On one of the pads there is placed a parking brake lever.

In a drum brake mechanism with two working cylinders beneficial effect increases in times due to rotation of the drum while moving the car, which tends more to press itself to it during braking. As a result, the necessary force on the brake pedal reduces. It is enough now the driver quite easy to press the pedal the drum pads to touch the drum. After this the effect begins to work as a kind of "booster."

Useful life of brake pads for drum system is up to 100.000 kilometres. Such a long life of drum brake system is easy to explain: it's a very simple and very safe construction. Drum systems shoes have a large working area, so the wear is much slower. If the slave brake cylinders are faultless, the system works without maintenance for several years.

• a significant increase in braking distance;
• whistling sound during braking;
• change of the vehicle path during hard braking;
• vibration or the wheels wobble during braking;
• material lining projection out of the shoe.

• failure to comply with the part operation terms and rules;
• sporty driving style;

One of the main signs of brake linings malfunction is a loud whistle when braking. Modern brake pads have a special surface that contributes to a loud noise when braking, if the pads have worn out. In this case, you should replace the linings or the pads themselves as soon as possible.

The limit for operating the brake linings is 15 000-20 000 kilometers. Its excess can have a negative impact on the quality of braking and traffic safety.

Repair of the brake linings is not carried out. Damaged components must be only replaced. Connection of the brake shoe and lining depends on the pads type. Replacement of the brake linings should be carried out only at a service station, because the braking safety depends on the correct installation of brake linings.
