Steel
braided lines are used in place of conventional rubber lines which
carry high pressure fluids. The steel braiding helps the hose to
keep its shape when hydraulic fluids are being forced through, such
as brake or clutch fluid. Usually found as standard on high performance
vehicles or fitted as a aftermarket performance part, real braided
lines will provide stronger braking and feel.
Real steel raided lines should not be confused with the cosmetic
braided hose covers which can be fitted over existing rubber hoses
and which give no real performance benefit.
