Upgrade the braking on your BMW 1 Series F20 and F21 with these HEL Performance stainless steel braided brake lines designed for cars equipped with Brembo calipers. Perfect for M135i and M140i as well as other RWD F20 F21 models, this front and rear brake hose kit delivers sharper pedal feel, improved braking response and consistent performance on the road and track. If you are searching for BMW F20 brake lines, BMW F21 braided brake lines, M135i braided hoses, M140i brake hoses or Brembo caliper brake lines for BMW 1 Series, this is the competition-grade solution trusted by enthusiasts.
HEL braided brake lines replace the standard rubber brake hoses with a PTFE inner and stainless steel braided outer for strength, precision and reliability. The result is a firmer pedal and a more direct connection to your Brembo calipers, eliminating the spongy feeling associated with OEM rubber lines under hard braking. We have fitted these ourselves and customer feedback has been outstanding for pedal feel and control.
