We have to choose those with CCC mark, and the manufacturer's name marked on it is detailed, the production date is also very formal manufacturers, so that we can pick a guaranteed product.
Secondly, we have to choose the corresponding products according to the model of their own cars, one by one!
The body letters "HR" designate hydraulic hose with a standardized expansion volume; 'HL' designates hydraulic hose with a low expansion volume; and "A" designates hose designated for air brake systems; "V" indicates hoses for vacuum braking systems.
Finally, when we pick to carefully check whether there are bubbles, corrosion and cracked condition.
At present, the domestic automotive industry brake hose implementation of mandatory national standards GB 16897-1997 "brake hose". This standard is based on the U.S. Federal Motor Vehicle Safety Standard FMVSS 106:1993 "Brake Hose", but compared to it, there are actually deviations. A lot of experimental projects are not very perfect, and the system performance index is still on the low side.
The recent national mandatory standard GB 16897-200X "Brake Hose Structure, Performance Requirements and Experimental Methods" has modified the relevant definitions and tests, improved the new energy requirements of brake hoses, and enhanced the high temperature pulse test of hydraulic brake hoses.
