The saddle is one of the most important safety systems on cars, but there are many misconceptions about the way car users operate and maintain them. Here are 6 harmful misconceptions about car braking that drivers should know.
Phanh ABS helps vehicles stop faster
In fact, the main goal of ABS braking is to keep the controller from losing control, not to stop the vehicle earlier. When the wheel is stiff, the vehicle will slide and cannot be steered. At this time, ABS brakes will intervene to prevent slipping by activating continuous release brakes (40 reps/second). At the same time, keep the wheels moving enough so that the tires can maintain traction and help the driver to steer, avoiding danger, especially when there are obstacles in front.
When traveling on dry road, ABS brakes can make the stopping distance a little longer, but in return, they are stable and safe.
Phanh says "the end of the line" is due to wear and tear on the brake account
The sound of "going around the cage" when braking does not always mean that the brake handle is broken, even if the brake handle can make such a sound, especially when the integrated wear indicator (also known as a small piece of metal designed to create noise) begins to rub against the brake plate.
The sound of "casset" can also occur for many other reasons such as dirt, moisture, rust, enuresis, or weather.
If the noise disappears after a few brakes, there is nothing serious about car brakes. However, if this shout is prolonged, or switches to "confused" sound, the driver needs to take the car for more careful inspection.
Permanent brake force
Many people think that the brake plate is a large metal block and will last longer than the age of the vehicle. However, the brake plate (road wheel) also worn over time like the brake pad. In fact, each time the brake is pressed, the brake handle presses strongly on the plate with great force, generating heat and friction.
Gradually, the metal is eroded, warped or cracked. The brake pads are usually about 80,000 - 110,000km long, but can break down sooner if you often step on the brake excessively.
According to experts, car users can take care of the brake discs by applying the brake plate up to 2-3 times during the entire use period.
When the thinning of the brake disc is below the safety threshold, it will affect the braking performance. At that time, quickly replace it to ensure safety when driving.
Brake fluid needs no replacement
This is a misconception that can cause many drivers to be in serious trouble. In fact, the brake oil absorbs moisture from the air, causing the boiling point to drop sharply. The new brake oil can withstand temperatures above 200oC.
However, once steam has penetrated, it will only be able to withstand the boiling temperatures of nearly 100oC. When too hot, the oil can boil, creating a gas bubble that causes the pedal to "brake", causing a reduction in braking efficiency.
On the other hand, the water in the oil causes rust inside the system. Therefore, replace the brake oil every 2 years or according to the recommendation of the automaker.
Low numbers help save on brake pads
Swing down to slow down seems to be a smart way to help the brakes hold longer thanks to a slight reduction in the braking system's pressure. But this does not really help car users save money.
The car's wheels are designed to withstand heat and friction all day. While continuously using a lower gear ratio to slow down can put more pressure on the gearbox and clutch of the car.
And if the gearbox is broken, car drivers will have to face expensive repair invoices, which are often 5-10 times more expensive than the cost of changing the brake lining.
In fact, using engine brakes will be very useful for cars on steep roads to maintain control. But for daily travel, drivers only need to use brakes.
Larger brakes will stop better
The large accelerator helps to generate heat better, making cars look cooler and more useful when pulling heavily, racing or going downhill, so there is no need to argue about this.
However, under normal driving conditions, the factors that determine the stopping distance are the tires and the road surface, not the size of the brake disc. So, invest in a set of good quality tires instead of spending money to upgrade large brake discs.
