Some matters needing attention in the installation and maintenance of automobile brake pads

The owner often reflects that the brake pads are not wear resistant. This is actually an early wear phenomenon. The reasons for this early wear are mainly the following aspects.

1. The material and structure of poor brake discs or drums can easily cause early wear of the brake pads.

2. Due to the long-term use and damage of the brake caliper of the brake system, the brake will not return, causing the discs and discs (drums) to drag and wear over a long period of time, causing severe wear and tear.

3. The unsuitable materials used for the brake pads and the unreasonable design density of the brake pad friction layer (which is too small) are also one of the causes of serious brake pad wear.

4. The original vehicle brake pads have a small design area, and are used for long-term speeding, frequent braking, overload work, and long-term high temperature, which are also the main reasons that cause serious brake pad wear.

For these various reasons, it is recommended that you use the brake series (0e product) discs, pliers, and brake pads that are compatible with your car. The best time to replace the brake pads is that the thickness of the brake pads of the disc brakes can be checked by pressing on the brake pads. Inspecting the thickness of the brake pads on the brake pads of the drum brakes, the brake pads must be removed from the brakes. Pull it out for inspection. However, whether it is a brake disc on a disc brake or a brake disc on a drum brake, the manufacturer has specified that the thickness should not be less than 1.2mm, because, through all practical measurements, the brake pads wear out before and after 1.2mm. Peel faster. Therefore, the owner should check and replace the brake pads on the brakes at this time or before. In the normal driving situation, the front brake has a brake pad life of 30,000-50,000 kilometers, and the rear brake pad has a service life of 12 Ten thousand - 150,000 kilometers.

Precautions before and after replacement of brake pads

First of all, we must check whether the brake pads are genuine accessories (that is, ancillary products). Whether the integrity of product packaging, anti-counterfeiting marks, and packaging marks are consistent with the marks on the brake pads. The product model is consistent with the content of the certificate. Before lifting the vehicle, the brake fluid should be covered and the tire screw should be loosened. If you use simple jacks to support, jacks should be supported, and reinforce the wheels without replacing the brake pads. Remove the tire, loosen the clamping screws, and check the screws and pliers to slide the guide rod to remove the mud and sand from the top and maintain the lubricant. Remove the old brake pads and check the degree of wear of the brake discs. Severe wear (single side depth 3mm) should be replaced with a new brake disc with a cycle time of 80,000 - 120,000 kilometers. Otherwise it will speed up the wear of the newly replaced brake pad, and the direction of vibration when the brakes, the braking force is too small.

It is worth noting that: the installation of new brake pads should be distinguished inside and outside, the friction surface of the brake pads should be to the brake disc, so that the disc with the appropriate. Attachment, fastening the body. Before tightening the caliper body, apply a tool (or special tool) to push the plug on the caliper back into place to allow the caliper to fit into place. If you need to replace the brake pads on the drum brakes, you are recommended to go to a professional workshop to ask professionals to operate to avoid errors.

After installing the brake, the tire should be reset. When installing the tire screws, the corners should be tightened to help protect the tires and the brake hub. At the same time, it is also necessary to check whether the wear condition of the tread and the edge is normal. It is better that the left and right wheels can be changed and used regularly, which will help to prolong the service life of the tire. Finally, brake fluid needs to be checked. The brake fluid should be replaced and added periodically. At the same time, the brake fluid used should be of the same grade as the original brake fluid. This will help remove dirt from the brake line and make the brakes more sensitive. If brake fluids of different brands are used together, chemical changes will occur, resulting in the deposition of sludge and inorganic salts in the braking system. Over time, it will block the pipeline and cause brake failure. The consequences are unimaginable.
