Car brakes sampling failure rate exceeds 3%

According to the State Administration of Quality Supervision, Inspection and Quarantine issued a 2013 national product quality supervision and spot check results announcement, the related automobile sampling project also includes automotive brake linings, automotive hoses, automotive transmission belts, automotive lamps and motor vehicle coolant Wait. Among them, the failure rate of automotive brake linings commonly referred to by the industry as "brake pads" exceeds 13%.

The current annual output value of the Foshan auto parts industry has exceeded 30 billion yuan, and there are a large number of large- and small-scale enterprises. In this random inspection, many Foshan auto parts companies' products were included in the scope of spot checks. From the point of view of the total spot check, although the individual batches of products of individual companies in Foshan were unqualified, the overall performance was stable.

Brake Pad: Frictional coefficient deviation affects the braking performance In the tested auto parts, the most frequently contacted car owners are the brake linings for automobiles, commonly known as “brake pads”. A total of 129 batches of products produced by 129 companies in 10 provinces and municipalities were sampled. As a result, it was found that there were 17 batches of products that did not meet the requirements of the standard, involving the specified allowable friction coefficient, impact strength, friction coefficient, and package marking items.

According to statistics from the reporter, compared with other types of auto parts products that were spot checked this time, the brake lining of automobiles has the highest failure rate, exceeding 13%. When visiting the Foshan Express Auto Parts Market, businessmen introduced that the so-called brake linings for automobiles are commonly known as “brake pads” or “friction pads”. In automobile accessories, brake linings for automobiles are consumables that are used daily. It may be used at any time. In general, the quality of the brakes is one of the decisive factors in the quality of the brakes. Therefore, if the owner is private to purchase the brake pads, the merchant will usually recommend the more expensive Dachang Laochang factory accessories.

According to reports, the brake pads are mainly determined by the friction coefficient and impact strength of the accessories. Among the 17 batches of unqualified products of the 17 companies that were found during the spot check, the main problem was “specified friction coefficient allowable deviation”; secondly, the products that were found to have “impact strength” were unqualified. In addition, some brake linings for automobiles have been found to be unqualified because they have no specified friction coefficient. Among the 129 corporate products that were spot-checked, reporters found that 11 of the 11 batches were Foshan Auto Parts. Only one company detected the problem of non-conformity.
