6.5. Brake hoses
It is necessary to check hoses of the brake system at least two times a year.
For the prevention of sudden failure of the brake system carefully check a condition of all pipelines and connections, paying special attention to the following:
Metal pipelines should not have scratches and the centers of corrosion and have to be located far from sharp edges which can damage them.
The brake hose has to be elastic, not have anguishes and cracks and has to be closed strongly up in tips. The carving of tips of a hose should not have damages. If when pressing a brake pedal the hose is inflated, means threads of cords are torn. At detection of any of these defects the hose needs to be replaced. On hoses the mineral oils and lubricants dissolving rubber should not get.
All brackets of fastening of pipelines have to be whole and are well fixed. Weakening of fastening or destruction of brackets leads to vibration of pipelines which causes their breakages.
Leak of brake fluid from connections of the main cylinder with pipelines and a tank is not allowed.
At detection of malfunctions replace the damaged details new. Irrespective of their state, replace flexible hoses new after 120 thousand km of a run or after five years of operation of the car to warn sudden gaps because of rubber aging. The brake hose rubbing against a suspension bracket detail wears out and finally fails.
For check use a mirror and illumination.
