HEL Performance Braided Brake Lines Hoses Kit – BMW 1 Series E81 E82 E87 E88, 3 Series E90 E91 E92 E93, Z4 E89 – Black Stainless Steel Front & Rear Flexi Pipes Upgrade, Direct Fit, M Sport Compatible – Lifetime Warranty (135i 320i 335i Z4 35i)

HEL Performance stainless braided brake hose set for BMW E8x, E9x and E89

Transform pedal response and stopping confidence with this complete black-sheathed stainless braided flexi hose set for BMW 1 Series, 3 Series and Z4. The HEL Performance assembly replaces ageing rubber brake pipes with a reinforced PTFE core wrapped in 303-304 stainless braid and a durable black PVC outer. The result is a firmer pedal, reduced hose expansion under pressure and repeatable braking on fast road and track.

We run these on our own cars and have fitted them for countless customers. Feedback is unanimous. Sharper bite, cleaner modulation and consistency you can feel, especially when braking hard or once the system is hot. The stainless end fittings resist rust far better than plated alternatives, ideal for UK road salt and year-round use.

Why this upgrade works

• Immediate pedal feel, minimal line swell under heavy braking
• Direct replacement for factory flexible pipes, no modifications required
• Stealth black outer for an OEM+ appearance on M Sport and non M Sport cars
• Stainless 303-304 fittings and braid for longevity and corrosion resistance
• Built by HEL to chassis-specific lengths for precise routing
• Suited to spirited driving, performance builds and track days
• Backed by the HEL Lifetime Warranty for long-term peace of mind
