Raise the car.
Clean the brake pipe.
Attention! The brake pipes are covered with a layer of plastic to protect against corrosion. If this layer is damaged, the pipeline must be replaced. Therefore, wire brushes, sandpaper and sharp objects should not be used for cleaning.
Check the lines from the brake master cylinder to the wheel cylinders using a hand lamp or flashlight.
Pipelines must not be bent or pinched. Otherwise, replace them.
On the moving parts of the car, the pipelines are connected to the wheel cylinders using brake hoses. The hoses are made of high pressure material, but over time they crack, swell and become damaged. In such cases, they must be replaced without delay.
To detect damage, bend the hose in different directions by hand. Do not twist the hoses, observe the color coding!
Turn the steering wheel left and right as far as it will go. In this case, the brake hoses should not touch the car parts.
Connection points of pipelines and hoses must not be wet.
Attention! If the reservoir or cuffs are wet, this does not necessarily indicate a malfunction of the master brake cylinder. Most likely, the fluid leaked out through the vent in the tank cap or through the seal of the cork.
