These are the HEL BMW 1 Series F20 F21 Brembo Caliper Competition Stainless Steel Front and Rear Brake Lines (INC. M135I & M140I) for your BMW 1 Series F20 (5 Door Hatchback) and F21 (3 Door Hatchback) including M135i & M140i.

Each HEL Performance brake line kit is assembled in-house from the finest quality stainless steel fittings swaged directly to hard drawn tensile stainless steel braided hose.

HEL Brake line kits eliminate that 'spongy' feeling often found with rubber hoses under extreme braking conditions - the time when performance is needed the most. By replacing the original rubber hoses with our complete system you will remove this sponginess and your braking will deliver new levels of precision.

Don't risk using inferior brake lines when you can trust HEL to improve braking reliability and performance - They use stainless steel in their lines and fittings, while most competitors use zinc plated fittings which are at risk from corrosion.
