This braided stainless steel line replaces the stock hydraulic hose connecting your clutch slave cylinder to the clutch master cylinder. Rubber hoses are known for swelling/deforming under pressure and vacuum, especially with age. This effects pedal feel. A firmer stainless line ensures less deformation and improved pedal feel.
