Currently, two varieties of brakes are applied in the automotive industry - disk and drums. There are variations of cars that are equipped with disk brakes on all wheels. However, there are also such vehicles that have a disc brakes in front, and the drums are drum. About this further in the article.

Disk and drum brakes, differences from disk brakes from drum

If you think that these systems work approximately equally, they are strongly mistaken, since disc and drum brakes do not have a single similar node. Disc brakes - an open braking system, where the rotation of the disk decreases by pushing its brake pads. The main component of the disk brake is a pair of pads.

The difference between the drum brakes is based on the fact that their mechanism is hidden inside the drum, and the braking itself is carried out by contacting the brake pads with the inside of the drum. If the pads are pressed in disk brakes, then in drum species, they slightly expand to slow down the drum and, therefore, the wheel.

Disc brakes, device, advantages and disadvantages

Disc brakes consist of the following components:

1. Caliper.
   
2. Guide pads.
   
3. Brake disk.
   
4. Piston.
   
5. Shoe wear signaling device.
   
6. Cylinder.
   
7. Sealing ring.
   
8. Brake pads.
   
9. Protective casing.
   
10. Guide finger.
    
11. Protective cover of the guide finger.
    

The advantage of the brake data is the open system easier to clean from pollution, and it is faster cooled. Its disadvantage is a relatively fast laying of the pad.

Drum brakes, device, advantages and disadvantages

The design of drum brakes includes:

1. Brake shoe.
   
2. Bottom Spring Pads.
3. Wheel hub.
   
4. Nut fastening hub.
5. Wheel cylinder.
   
6. Spring guide.
7. Scroll plank.
   
8. Top blast spring.
9. Shield brake mechanism.
10. Manual brake drive lever.
11. Hand brake drive lever finger.

The dignity of the drum brake system is the simplicity of the design, and the lack of ventilation is considered its disadvantage. As a result, drum brakes are much more overheated than disk systems, which significantly reduces their effectiveness.

Brake pads disc brakes, why they wear out quickly

The pads are produced faster as a result of the fact that the clamping force of the brake pad to the disk is higher than several times than in the drum mechanism. In addition, unauthorized particles of dust and sand flying from the road are negatively affected.

What brake mechanisms are more powerful

Undoubtedly, disc brakes are much more efficient during braking than drum analogs. In fact, disc brake systems occurred only because the drums could not provide optimal braking speed for modern TS, which has significantly increased dynamics and speed.

Even if the drum system is completely new, according to its braking efficiency, it will continue to significantly give up a disc. To date, there is noticeably observed a gradual displacement of drum systems and their replacement to disk. Today it is difficult to find the TC, which use drum brakes on the front wheels. For security reasons, actually all manufacturers on the front wheels are installed disc brake.

As for the rear wheels, then drum brakes are still mounted in order to reduce the car. In other words, drum brakes can be mounted only on rear wheels of state employees. This is permissible, since such powerful motors, as a rule, are not installed on such TCs, and their dynamics are not so large. Drum brakes are quite capable of cope with it.

Drum brakes why they are cheaper to maintain

If we talk about cash flows, then the advantage of drum brakes, since the pads in this system are significantly less than the replacement, rather than the blocks of the brake disk system. Thus, the average service life of the pads of disk systems is about 25,000 mileage kilometers. As for the drum pads, they are able to work even 60 thousand kilometers, although these parameters are significantly dependent on the style of the ride.

Disc brakes why they are afraid of water puddles

Disc brakes one drawback - they are afraid of puddles. In the process of strong braking, the disk is able to heal greatly, so the cold water getting into it has a negative effect - the disk can simply burst.

Although the strong heating of the brakes is only in some cases, for example, if the driver is driving on a protracted descent on a highly overloaded car and does not know anything about braking by the engine.

Tips pro, disc or drum brakes and what is a stock of security

The drum brakes are not installed on the prestigious dynamic car, and if the TC is equipped with a drum system, it means you should not expect super-dynamics from it and special suquestness. This is definitely a budget car that is bought only in the case when saving funds go on the fore.

Naturally, disk systems are better than drum, however, at the same time, they are more expensive in acquiring and in service. Currently, the set of vehicles are equipped with both disk brakes mounted on the front wheels and drum systems that are installed on the rear axle of the car.

As a result - according to the safety measures, the vehicle has a permissible braking path (as a result of the effective operation of the front disc brakes), and the auto owner, while not carrying huge costs. In addition, many drivers prefer a quiet manner of driving, without overloading their cars, with what drum brakes will be perfect.

It is important to remember that the safety reserve is never superfluous, in particular, it is necessary in emergency cases, which, unfortunately, no one is insured.
