The Thickness And Replacement Of Brake Pads
May 19, 2021
Because the replacement cycle of brake pads is relatively long, people do not pay much attention in daily life, but everyone knows the importance of brake pads. Therefore, when you have time, you can carefully check your brake pads to see if they need to be replaced. The car masters here share if it is judged that the brake pads need to be replaced 3 kinds of phenomena, when measuring the thickness, there is a raised mark on both sides of each brake pad, the thickness is about 2-3mm, which is also the ultra-thin brake disc replacement Limit, if the thickness of the brake pad is parallel to the mark, it must be replaced.
1. According to the thickness of the brake pad
As the thickness of the brake pads becomes thinner, the braking performance will drop sharply, affecting driving safety. Usually the thickness of the new disc is about 1.5cm. When the brake disc is worn down to only 0.5cm, you need to increase your frequency of inspection. If the brake pads wear only 0.3 cm, you must replace them in time. This is the limit for replacing the ultra-thin brake discs. Don't delay, so as to avoid the danger of personal and property damage. The other is that there are raised marks on both sides of each brake pad, with a thickness of about 2 to 3 mm. If the brake pad is already parallel to the mark, it must be replaced. For some better models, when the brake pads are too thin, the position of the handbrake light on the instrument will prompt, and the car should pay attention to it in time.
2. Listen to the brake sound
When you step on the brake, try to listen to the sound of the brake. If you hear a sharp sound like an iron grinder, pay attention to that the limit marks on both sides of the brake disc have rubbed against the brake, which proves that the brake pad has exceeded the limit and must be replaced at this time. You should also know that car brakes are much more expensive than brake pads, so at this time you not only have to replace the brake pads, but also check the brakes.
3. Braking response and braking
As the brake pads become thinner and thinner, the brake response of the car also becomes slower. In order to obtain the previous braking effect, we need to step on the brake deeper and heavier. Before stepping on the brakes, it is found that the effect of the half-travel brake is significantly weakened, and when the brakes are softened and cannot stop, check whether the brake pads need to be replaced.
In fact, these methods are due to our inaccurate grasp of the condition of our vehicle, so the brake pads of the vehicle must be checked. In addition, some experienced drivers can easily determine whether the brake pads need to be replaced.
Look again at the friction coefficient relationship of the brake pads:
EE grade: 0.25-0.3, suitable for use in European and American autos, with large brake discs and low friction coefficient;
FF grade: 0.35-0.45, international standard friction coefficient;
GG grade: European model: 0.45-0.5;
HH level: 0.55-0.6, specifically for racing.
Teach you a few tricks to check the brakes, don’t forget to look at the thickness of the brake pads, the introduction of how to measure the thickness of the brake pads, hope it will be helpful to you
