On hydraulic brakes, the wheel brake calipers are operated by oil pressure generated by the master brake cylinder at the end of the brake pedal. The oil is pumped to the wheel brake calipers through a system of brake lines or tubes. Rigid brake lines can't do the trick entirely though, as wheels are attached to moving suspensions, allowing them to follow the road. That's why at some point, flexible brake lines or brake hoses are indispensable to make the connection complete.
Brake hoses are manufactured from reinforced rubber, which is impervious to oils and fluids. The hoses must be able to withstand the extremely high pressures in the braking system. Brake hoses are exposed to regular hydraulic movement as well as the outside environment, degrading the rubber over time. The hoses will get porous and elastic, allowing water to penetrate into the brake fluid, reducing its boiling point. The elasticity will create a spongy feel in the brake lever, decreasing performance of the braking system. And at some point, the brake hoses will break or shear, causing a direct brake failure.
The quality of a brake hose largely depends on the rubber quality and of the harness construction responsible for the form stability when pressure is applied. Bad rubber quality will degrade swiftly, an inferior harness will cause elasticity, manifesting itself in a spongy brake pedal and poor brake performance. To guarantee a minimum quality standard, DOT-, SAE- and FMVS set up standards to which all brake hoses must comply.
