As the core component of the automobile brake system, the brake pad directly affects the braking performance and driving safety of the vehicle. This article will introduce in detail how to choose the high quality brake pads, as well as the correct installation and replacement methods to help car owners better maintain the safety performance of their cars.

The importance of brake pads

The brake pad is one of the most important components in the automobile brake system. It generates braking force through friction with the brake disc, thereby slowing down or stopping the movement of the vehicle. High-quality brake pads not only provide reliable braking performance, but also respond quickly in emergency situations to ensure the safety of the driver and passengers.

Components of the brake system

The automobile brake system mainly includes brake pedal, brake master cylinder, brake pipeline, brake wheel cylinder, brake pad and brake disc. These components work together to complete the braking task. The brake pad is located between the brake disc and the brake caliper, and decelerates or stops by friction.

The working principle of brake pads

When the driver steps on the brake pedal, the hydraulic oil in the brake master cylinder is compressed and transmitted to the brake wheel cylinders of each wheel through the brake pipeline. The brake wheel cylinder pushes the brake caliper to clamp the brake disc. At this time, the brake pads contact the brake disc and generate friction, thereby slowing down or stopping the vehicle.

Risk of poor quality brake pads

Inferior brake pads may cause braking performance to decrease, or even fail in an emergency, which seriously threatens driving safety. In addition, low-quality brake pads will increase the wear rate of the brake disc, shorten its service life, and increase maintenance costs.

How to choose the high quality brake pads

Material and performance

High-quality brake pads are usually made of high-performance composite materials with good wear resistance and stable friction coefficient. Common materials include metal matrix composites, ceramic matrix composites, and organic fiber matrix composites. When selecting, pay attention to the material description and technical parameters of the product.

Brand and Quality

Choose well-known brands of products can be more secure. Well-known brands usually have a strict quality control system, and the products have been tested and verified many times, and the performance is stable and reliable. You can check the relevant reviews and user feedback to understand the performance of different brands.

Price and Cost Performance

Price is not the only criterion for measuring the quality of brake pads. Within a reasonable price range, it is more important to choose products with higher cost performance. You can find the most suitable product by comparing multiple brands and models, considering performance, quality and price.

Purchase Notes

When purchasing brake pads, make sure that the selected product is suitable for your own model. At the same time, it is also necessary to pay attention to the production date and shelf life of the product, to avoid the purchase of expired or about to expire products. It is recommended to choose regular channels to ensure genuine goods and after-sales service.

Service life and replacement cycle of brake pads

Life under normal driving conditions

Under normal driving conditions, the brake pads of the high quality can generally be used for 30000 to 50000 kilometers. The specific life depends on factors such as driving habits, road conditions and vehicle load.

Accelerated wear in harsh environments

In the case of frequent braking or heavy load driving in mountainous areas and highways, the wear of the brake pads will accelerate and may need to be replaced in advance. It is recommended to regularly check the thickness of the brake pads to ensure that they are within a safe range.

How to judge the need to replace the brake pads

Auditory signal: abnormal sound

If you hear a sharp metal friction sound or other abnormal sound when braking, this may be a sign of severe wear or damage to the brake pads, and should be checked and replaced in time.

Visual signal: thickness reduction

Check the thickness of the brake pads regularly. When the remaining thickness is lower than the minimum value specified by the manufacturer (usually 2mm), it should be replaced immediately.

Sensory signal: braking force weakened

If you feel that the braking force is significantly weakened or the braking distance becomes longer during the braking process, it also indicates that the brake pads may have been severely worn and need to be replaced in time.

Installation and replacement of brake pads

Preparations: Tools and Accessories

Before replacing the brake pads, you need to prepare the necessary tools, such as wrenches, screwdrivers, jacks, etc. At the same time, new brake pads and other necessary accessories need to be prepared.

Removing the old brake pads

First, use a jack to lift the vehicle, loosen the tire bolts, and remove the tire. Then remove the retaining bolts on the brake calliper and carefully take out the old brake pads.

Installing new brake pads

Put the new brake pads into the brake caliper, making sure they are in the correct position. Refit the brake caliper and tighten the retaining bolts. Finally, replace the tires and tighten the bolts.

Debug and Test

After the replacement, the brake should be tested on a flat open ground to ensure the normal operation of the brake system. If there is any abnormality, it should be adjusted or checked in time.
