Some drivers think that although the vehicle to the maintenance period, but the technical condition is good, if the demolition, especially by hand washable, improper assembly operations, will lead to mechanical adverse consequences. Due to the above reasons, often can not be promptly maintained, causing the vehicle disrepair, affecting vehicle performance and normal use. Nissan brake distribution valve, due to regular and timely maintenance, replacement of new oil, the result of old oil aging, resulting in dirt, so that the piston can not be in the normal operation of the cylinder.
