How often are the brake pads changed?
30,000 to 50,000 kilometers
The replacement cycle of brake pads depends on a variety of factors, including the number of kilometers traveled by the vehicle, driving habits, driving road conditions, etc. In general, brake pads need to be replaced once between 30,000 and 50,000 kilometers, but this cycle is not absolute. If the brake pads wear to a certain extent, such as the thickness is less than 3mm, or abnormal wear, abnormal noise, etc., should be replaced immediately. Some models have brake pads with induction lines, and when worn to a certain extent, the alarm light on the dashboard will light up, indicating that it needs to be replaced. Therefore, it is recommended to regularly check the use of brake pads to ensure driving safety
Brake pads how to see the degree of wear
There are mainly the following ways to determine the degree of wear of brake pads:
Look at the thickness: under normal circumstances, the new brake pad thickness is about 1.5 cm. For safety reasons, when the brake pads wear to only 0.5 cm, you can consider replacing them. The owner can directly observe the thickness of the brake pads on the rim of the tire.
Listen to the sound: If there is an abnormal sound when braking, such as a harsh metal sound, and it does not disappear for a long time, this may be a sign of serious wear of the brake pads.
Look at the dashboard: Many cars are now equipped with brake system reminders. If there is a problem with the brake pads, the brake warning light on the dashboard will light up, and the owner needs to check the brake pads in time to see if they need to be replaced.
Brake effect judgment: If the braking effect is poor during the braking process or the pedal position is low during emergency braking, it indicates that the wear and tear of the brake pads may be more serious and need to be replaced in time.
In addition, you can also use a brake pad measuring instrument (brake pad measuring calipers) to measure the thickness of the brake pads, or judge the wear of the brake pads by feeling the force of the brakes. If the brakes become limp, or you need to use more force to slow down when you apply the brakes, it may be a sign that the brake pads have worn out.
In general, there are many ways to judge the degree of wear of brake pads, and the owner can choose the right method to check according to the actual situation. If it is suspected that the brake pads have been worn to the extent that they need to be replaced, it is recommended to contact a professional automotive maintenance technician as soon as possible for inspection and maintenance to ensure driving safety.
Do we need four brake pads
When replacing brake pads, it is not necessary to change four together, but to decide according to the degree of wear. Usually, a pair of brake pads are replaced at a time, that is, the brake pads of the front or rear wheels are replaced together. If the brake pads are seriously worn, not replacing them in time will lead to a sharp decline in brake performance and affect driving safety. Brake pads are composed of steel plate, adhesive insulation layer and friction block, which are the most critical safety parts in automotive brake system. Therefore, the choice of a good brake pad is crucial to driving safety. When replacing the brake pads, special tools should be used to ensure that the gap between the brake pads and the brake disc is appropriate to achieve the best braking effect.
