Each hose is tested to 3000 PSi (207 bar).  The braided stainless lines have a clear plastic jacket to provide further protection from road debris like salt and dirt.  The benefits of stainless lines include:

1. Improved pedal stiffness
2. Reduces braking distance during panic stops
3. Eliminates pedal sponginess under heavy braking
4. Gives immediate brake pedal response
5. Provides compatability with all brake fluids
6. Design allows high temperature operation and longer life
