Replacing old worn out rubber hydraulic hoses is a must! Braided stainless steel lines are the best way to improve pedal feel. This braided stainless steel line replaces the stock hydraulic hose connecting your clutch slave cylinder to the clutch master cylinder. Over the years Condor Speed Shop customers have experienced a difference in quality, performance and reliability from our clutch line manufacturer, BrakeQuip®. For over 20 years, BrakeQuip® has been the professional’s choice and is a leading manufacturer of performance hose and fittings. Don’t be misled by other brands that claim performance, but buy all their products overseas. 100% of our hose is proudly made in the USA and assembled in sunny Florida using a 4-wire 304SS braid and PTFE inner core. Condor Speed Shop’s clutch line fittings and hose tolerances are engineered to match for a compatibility exclusive to BrakeQuip®. All clutch lines are pressure tested to almost 3X the rated working pressure prior to shipment to ensure safety and performance. Pressure tests have shown that braided stainless lines expand less than 50% when compared to brand new rubber replacement hoses at 1,500psi. Technical features: Fully compliant with DOT Standards (MVSS-1006) Lines burst-tested to 6000psi(maximum tested pressure from a BMW braking system is 1200psi) Teflon® inner line covered with a woven layer of stainless steel and covered with an abrasion-resistant material.
