Na usoro ndochi, ụfọdụ ụlọ ọrụ nwere obi ọjọọ, n'ihi na ha chọrọ ịchọ ime ihe ike, ọ bụghị naanị ogo ekweghị ekwe, kamakwa ọnọdụ siri ike ga-akpata nnukwu nsogbu na nchekwa nke owner. How to tell the truth?
1. Look at the product packaging and certification. Ewepụtara site na ndị na-emepụta oge, mbipụta nkwakọ ngwaahịa ahụ, ọnụọgụ akwụkwọ ikike akọwapụtara, na ọnụ ọgụgụ nkwakọ ngwaahịa, akara ngosi, wdg, ya mere Ọ dị mkpa iji chọpụta ma akara ngwaahịa a na - egbochi, akara mgbochi na akara ngosi kwekọrọ na akara ngwaahịa ahụ kwekọrọ na ọdịnaya nke asambodo ahụ. If the packaging is simple, the information is incomplete or no, or even "three no" products, you should consider it carefully. In addition, whether it is disc or drum, the manufacturer has strictly specified its thickness, and the owner can measure it by himself.
2. Compare whether the price is reasonable. Prices on the market range from dozens to hundreds, and businesses in the sale are emphasizing the original factory, in addition to price differences, for quality differences, businesses are also well aware. Ha abụọ nwere ike ikwu na ọ bụ otu nha na ụdị, mana ọnụahịa ha dị iche iche. Therefore, a point of price, a point of goods, is indeed the standard for judging the quality of things, as long as it is lower than the market price, it must be inferior.
3. Lelee ọdịdị ahụ. High quality in the proportion of friction materials in particular, and the appearance looks full of color, there will be a smooth touch, will not easily off the paint, good workmanship. A ga-eji ọgwụ mee ihe iji belata ụgwọ ọrụ, ọrụ na uche dị ukwuu ga-eji ya, a ga-acha ọbara ọbara, na-acha uhie uhie bụ nke ochie nchara.
4. The friction coefficient of the friction coefficient is too high or too low will affect the brake performance, especially in the high-speed emergency braking, the friction coefficient is too low will appear insensitive, the friction coefficient is too high will appear tire lock phenomenon. According to the SAE standard, the friction plate will choose the FF grade rating coefficient, that is, the friction rating coefficient is 0.35 ~ 0.45. In addition, according to the national standard, the appropriate working temperature of the friction sheet is 100 ~ 350 ° C, and the coefficient of friction will drop sharply when the inferior temperature reaches 250 ° C, and there is a failure.
