Internal hose degradation from environmental exposure and rubber aging can lead to pressure loss, uneven caliper response, and internal fluid leaks that compromise braking performance. This replacement DFC True-Arc brake hose offers superior structural integrity to restore immediate hydraulic response, prevent volumetric expansion under heavy-duty braking, and eliminate common failure points associated with aging fluid lines.
Designed for severe-duty applications, this high-burst-pressure hose drop-in replaces OEM lines in BMW 330i models from 2010 to 2016. Its heavy-wall construction ensures durability against chaffing and abrasion, making it ideal for commercial fleet operations and industrial vehicle transport where reliability is critical. The hose features a 10mm inlet fitting with industry-standard INV thread for secure, leak-free connections.
- Overall Length: 17.78 inches
- Fitting / Outlet Size: 10mm INV thread
- Application: Commercial-Grade / Heavy-Duty Fleet / Passenger Automotive Cross-Over

Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of routing hoses to prevent chassis chaffing and ensure full-lock steering clearance. Always verify that the hose length and fitting threads match your vehicle’s existing components before installation. Proper line routing and secure mounting brackets on heavy-duty frames are critical to prevent chafing, reduce vibration, and maintain hydraulic integrity during demanding fleet operations.
Before ordering, physically inspect your existing brake line length, banjos, and flare fitting threads. Variations in wheelbase and production batches can alter line routing on fleet and utility vehicles. Confirm measurements to ensure perfect fitment and avoid costly installation errors.
