What is?
the outer rubber tube is coated with a brake oil passage high tensile steel wire, the outermost layer plus a layer of wear.

Function
Since the rubber elastic material is considerable, when the brake pedal , a sudden increase in hydraulic pressure, the brake pressure is partially converted to outward expansion of the rubber tubing having an inside diameter large thus forced. Brake pressure oil passage because of this change in the result, and the result is reduced braking force, the braking distance increases the braking time becomes long. This risk does exist for vehicle safety, especially at high frequencies, high strength brake, a rubber tube such defects will become more apparent. Solution is to use an alternative brake hose and rubber hose. Brake steel metal skin is mainly restricted throat swelling rubber hose, so that the braking force will not be lost because of the expansion.
