These phenomena are not noticed or may lead to brake failure

For car owners, brake failure is a very scary problem. Especially in the process of high-speed driving, once the brake fails, the car crash is not exaggerated. In fact, in the daily process of using the car, through many details, the owner can also judge the problem of the brake system, but these details are easy to be ignored by the owner.

1, partial brake.

To put it in plain English, when the brake is pressed and the vehicle is about to stop, the steering wheel will always deflect to one side more or less. The reason for this phenomenon is that the force of the left and right pump of the braking system is not uniform.

When the vehicle is in the process of driving, this bias brake is not easy to be detected, because at this time the brake drum or brake disc speed is relatively fast, and the friction between the brake pads is also very rapid, and the uneven pump force is very small under the high-speed friction. But when the vehicle is coming to a stop, this difference will become obvious, because the uneven force will make the two sides of the wheel stop time difference, the steering wheel will be biased to the side that stopped first. In this case, it is necessary to replace the pump in time.

2, the brake does not return.

The so-called brake does not return, that is, when the owner releases the brake pedal, the pedal cannot rise automatically, and the pedal has no resistance. If this phenomenon occurs, it is necessary to check whether the return spring and brake caliper are damaged, whether the brake fluid is missing, whether the brake sub-pump, pipeline and joint are leaking oil, and whether the main pump, sub-pump and other parts are damaged.

3. The car shakes when braking.

Under normal circumstances, the probability of this phenomenon in the old car is relatively large, mainly due to the brake drum/brake disc offset caused by, simply put, the brake drum/brake disc surface uneven or serious wear. If this phenomenon occurs on some vehicles that are not very old, it is often because the brake drum/brake disc is not qualified, or the owner of the brake is pressed hard under the continuous braking for a long time, resulting in the deformation of the brake drum/brake disc. In this case, it is recommended that the owner directly replace the parts with more serious wear.

4. Braking force cannot be provided immediately after the vehicle is started.

The principle of braking is that the engine provides pressure to push the brake pads to grab the brake drum, or push the caliper to grip the brake disc. General vehicles can be started with braking ability. However, some owners found that their vehicles to hot car after ten minutes to provide braking, in this case mainly because the pressure transmission pipe has a loss of pressure problem, resulting in its inability to provide braking force. The car mainly checks whether the vacuum booster tube of the main pump and the interface of the engine are cracked or loose.

5. Braking deviation.

Running off when you step on the brake is also a more common fault. In the process of driving the vehicle, the owner subconsciously steps on the brake because of sudden situations, the vehicle can not slow down in a straight line, but to one side, and the direction needs to be corrected after the end of avoidance.

Because this phenomenon is relatively obvious, it can attract the attention of many owners, but there are often repeated after maintenance, and even under multiple maintenance, it can not be improved. Because the vehicle is not serious, some owners will eventually be tired of maintenance.

In this case, the owner must first eliminate the problem of tire pressure and wear, because when the tire pressure or wear degree on both sides is different, the friction on both sides is wide, resulting in brake deviation.

Check the brake clearance, especially for vehicles without automatic adjusting arms, when the left and right wheel brake clearance is too large, there will be a difference in response time, resulting in brake deviation.

Check the braking torque. When the braking torque is different, it is also easy to lead to brake offset, such as different brake pressure, different friction loss of the brake system, brake pads or brake drum/brake disc there is oil.

The above content is for your reference only, and the specific problems should be analyzed according to the actual situation. Like the vehicle brake drum, brake disc, brake pads, calipers, etc., are the key components on the trailer axle, which have high requirements for material, strength, wear resistance, heat capacity, etc. Especially trailers, due to the large carrying capacity and more complex transport road conditions, the requirements for trailer axles and parts are higher than ordinary vehicles.

It is recommended that the owners still choose the products dedicated to the trailer, because whether it is the material, design or production process, will fully consider the use of the environment and needs of the trailer, stronger, more wear-resistant, higher heat capacity, not easy to appear soft or deformation, durable, can fully avoid stuck, stagnation, partial wear.

It is worth noting that some owners choose a maintenance-free trailer axle, maintenance-free ≠ inspection-free, although its maintenance cycle is long, owners still have to do a good job of daily inspection, especially the brake system, to prevent problems before they happen in order to better ensure safety.
