Questions And Answers
Can you produce according to OEM part numbers?
Yes, we specialize in OEM brake pads tailored to your specifications. We support on-demand customization, including LOGO, color, and appearance/size customization.
What are your main products?
We focus on the R&D, production and sales of automotive disc brake pads and drum brake pads, covering ceramic, semi-metallic, low-metallic and other formulations.
In addition, we also sell grease, clutches, brake adjusting arms, brake fluid, oil seals and other products.
Do you have different sizes for brake pads?
Yes, we provide matching sizes according to specific vehicle models, and customization is available based on OE/model codes.
Do I need to grind the brake pads before installation?
Grinding is prohibited! Guanying products are pre‑run‑in and ready for direct installation.
Will high temperature reduce braking performance?
For our high-quality products, the friction coefficient decay is ≤15% within 350℃.
Do new brake pads need to be broken in?
We recommend avoiding hard braking for the first 300 km to allow the friction material to fully mate with the brake disc.
How long is the service life of brake pads?
Unopened brake pads can be stored for 5 years. Actual service life after installation varies depending on road conditions, vehicle component aging, load capacity, driving speed, foreign matter entry, and other factors.
What vehicle models are your brake pads suitable for?
Our brake pads cover European, American, Japanese, Korean and all Chinese domestic vehicle models. We can provide a detailed model list for verification, and also offer R&D and customization according to your requirements.
What materials are available for brake pads?
Main materials include ceramic, semi-metallic, low-metallic and so on. Different materials are suitable for different driving needs and vehicle models.
What is the difference between ceramic and semi-metallic brake pads?
Ceramic brake pads have low noise and less dust but higher cost. Semi-metallic brake pads feature sensitive braking and high temperature resistance, but may wear the brake disc more easily.
What does a friction coefficient of 0.3μ mean?
The higher the value, the stronger the braking force. 0.30μ–0.45μ is the common standard range.
Do the products have noise-reduction designs?
Yes. Some models are equipped with shims or special formulations to reduce braking noise.
What is the hardness of the brake pads?
Hardness varies by material. Ceramic pads are approximately HRB 80–90, while semi-metallic pads are about HRB 90–100. Detailed test data can be provided upon request.
How can I tell when brake pads need replacement?
When the thickness is less than 3 mm, the wear indicator is triggered, or a metal grinding noise occurs during braking.
Does the friction coefficient of brake pads change with temperature?
There may be slight variations. However, our products are optimized to maintain stable performance within a temperature range of -40°C to 600°C.
Are the products treated for rust prevention?
Yes. The surface is coated with anti-rust treatment to prevent corrosion during storage and transportation.
What is the weight of the brake pads?
The weight varies by model. Generally, each set weighs between 0.5–2 kg. Specific data can be provided upon request.
Do the products have anti-counterfeiting markings?
Yes. Anti-counterfeiting codes or laser markings can be added upon customer request to prevent imitation.
What is the thermal expansion coefficient of the brake pads?
For ceramic materials, it is approximately 1.2 × 10⁻⁵ /°C. Detailed test reports are available upon request.
Can you provide wear rate data for the products?
Yes. The standard wear rate is ≤0.015 cm³/(N·km), depending on material and operating conditions.
Is there any quality difference between different production batches?
No. We follow strict standardized production processes to ensure consistent quality across batches.
What material is used for the brake pad backing plate?
It is generally made of low-carbon steel, treated with galvanizing or painting to enhance rust resistance.
What is the thickness of the friction material on disc brake pads?
It is generally 10–15 mm. Different models are designed according to braking requirements, and replacement is recommended when worn down to 3 mm.
Do the products have a cushioning layer design?
Some models feature a cushioning layer to reduce vibration and noise during braking, enhancing driving comfort.
What are the storage requirements for the products?
They should be stored in a dry and well-ventilated environment, away from direct sunlight and high temperatures. The shelf life is 3 years.
Can you provide 3D drawings of the product?
Yes. We can provide 3D drawings in CAD or STEP format for you to verify installation dimensions.
If the product does not meet our market requirements, can the formula be adjusted?
Yes. Our R&D team can adjust the material formulation based on your market feedback to optimize product performance.
What are the precautions for installing brake pads?
The brake disc should be cleaned before installation. Bolts must be tightened according to the specified torque. It is recommended to perform a low-speed break-in for the first 200 km of use and avoid sudden braking.
