HEL Performance Braided Brake Lines – BMW 1 Series F20 M135i & M140i (Brembo) 2010–2019

Overview
HEL Performance braided brake lines replace the factory rubber hoses on your BMW 1 Series M135i & M140i (F20) equipped with Brembo brakes, delivering improved braking precision and reliability. Rubber hoses can expand under pressure during heavy braking, creating a ‘spongy’ feel. HEL’s stainless steel braided construction eliminates this expansion, ensuring a firmer, more consistent pedal feel whether on the road or track.
