Abstract
The present invention provides a novel brake hose capable of sufficiently satisfying the fatigue resistance and the corrosion resistance, with the excellent expansion resistance. In a brake hose comprising a first reinforcing fiber layer ( ), an intermediate rubber ( ), a second reinforcing fiber layer ( ), and an external layer rubber ( ) provided successively on the outer circumference of an internal layer rubber ( ) for filling a brake fluid, the first reinforcing fiber layer ( ) is made of a polyethylene-2,6-naphthalate fiber. Accordingly, all of the fatigue resistance, the corrosion resistance and the expansion resistance can both be realized at a high level.
