The 10 most common problems with brake pad products

Here are the 10 most common after-sales problems and professional solutions for brake pad products, compiled based on industry experience:

1. Brake noise (high-frequency issue)
Reason: The new brake pads and old brake discs have not been fully worn in, scratches on the brake discs have not been treated, or the cylinder has poor return
Solution: It is recommended to drive for 300-500 kilometers during the break in period. If there is continuous abnormal noise, check the flatness of the brake disc or the condition of the cylinder
2. The brake is too soft
Reason: Incomplete exhaust during installation or deterioration of brake oil
Solution: Re empty the brake line air and replace DOT4 standard brake fluid if necessary
3. The brake does not return to its original position
Reason: The cylinder piston is stuck due to stains
Solution: Professional cleaning of the cylinder piston components requires the use of specialized lubricating grease
4. The new film emits smoke after installation
Reason: Organic components decompose at high temperatures (especially on long downhill sections)
Solution: This is a normal phenomenon, continuous smoking requires checking if different materials of brake pads are mixed together
5. Brake direction deviation
Reason: Uneven braking force on the left and right wheels
Solution: Four wheel brake system pressure testing is required, and it may be necessary to replace brake pads from the same batch
6. Pedal bounce
Reason: Abnormal wear and groove on the brake disc
Solution: Brake discs/pads must be replaced simultaneously, and individual replacement is prohibited
7. Rapid wear and tear
Reason: Poor quality materials or intense driving
Solution: Provide legitimate channels for purchasing vouchers to apply for quality inspection, normal wear and tear is not covered by the warranty
8. The online shopping model does not match
Solution: Vehicle VIN code needs to be provided for re matching, and self polishing is prohibited for use
9. Material replacement questions
Important reminder: NAO material cannot be directly replaced with semi metallic material, and the entire system needs to be replaced
10. Anti counterfeiting verification
Solution: Official channels can verify laser anti-counterfeiting codes, and products without warranty will not be covered

Note: All repairs involving the braking system must be carried out by certified technicians, and self handling may result in the warranty being invalidated. It is recommended to check the remaining thickness of the brake pads every 10000 kilometers (not less than 3mm).
