V3 Stainless Steel Brake Line Set

The BimmerWorld V3 Stainless Steel Brake Line Set is designed to replace the original rubber brake hoses on G80 M3 and G82/G83 M4 models, offering a significant upgrade in braking performance and feel. By substituting the expandable rubber lines with a non-expansive Teflon center core surrounded by braided stainless steel, these lines dramatically reduce hydraulic fluid displacement under pressure. This addresses a common cause of a soft brake pedal and can prevent premature brake fade, especially during demanding driving conditions. Constructed with a durable Teflon inner core and a braided stainless steel outer layer, these brake lines are built for longevity and resistance to abrasion. A clear plastic sheathing protects the stainless steel braid and allows for visual inspection for signs of wear or heat damage. The lines feature heavy-duty steel ends with swaged fittings for a secure and reliable connection. Exceeding DOT standards, these lines are rated for pressures up to 5,000 psi in short bursts and 4,000 psi for extended periods, demonstrating superior tensile strength and expansion resistance compared to standard rubber lines. Proper installation and maintenance are crucial for safety and performance. BimmerWorld recommends inspecting all brake components regularly, especially after track use, and replacing brake lines every 100 hours of track time or approximately 2-4 years due to natural aging and fatigue. It is imperative never to allow the brake caliper to hang solely from the brake line during installation or maintenance.
