BMW 4 Series F32 F33 F36 Braided Brake Hose Set - Black - HEL Performance

Transform pedal feel and stopping consistency on your BMW 4 Series with this HEL Performance front and rear braided hose package in stealth black. Designed as a direct replacement for the factory flexible pipes, this premium brake hose upgrade tightens response, improves modulation and delivers repeatable braking on fast road and track days. Ideal for owners searching for a BMW F32 brake hose upgrade, F33 braided flexi hoses, F36 performance brake lines, or black stainless brake hoses for 420i, 430i and 440i models from 2012 onwards.

We run these lines on our own cars and customer feedback has been consistently positive - firmer pedal, better feedback under pressure and confidence when braking hard from speed. Say goodbye to spongy, ageing rubber lines and enjoy crisp, consistent performance.
