R1 Concepts rncHSK-74027 Front Stainless Steel Brake Lines for 2015–2019 Audi Q3

The R1 Concepts Stainless Steel Brake Lines are engineered to deliver improved braking performance, enhanced pedal feel, and long-lasting durability for both daily driving and performance applications. These brake lines feature a PTFE inner core wrapped in a high-strength stainless steel braided weave preventing hose expansion under high hydraulic pressure and consistent brake response. An abrasion-resistant clear PVC outer coating provides added protection against chaffing, dirt, debris, and corrosion for extended service life.Unlike traditional rubber brake hoses that can expand under heavy braking, R1 Concepts Stainless Steel Brake Lines help reduce line flex to provide a firmer, more responsive brake pedal feel and more consistent braking performance. This improved hydraulic efficiency allows for better brake modulation and increased driver confidence during aggressive driving, towing, off-road use, or spirited street performance.Each brake line kit is United States DOT approved to meet strict safety and quality standards for street use. Precision-engineered fittings and included mounting brackets (where applicable) ensure a direct-fit installation with secure factory-style mounting.

• Stainless steel braided exterior for enhanced durability and reduced line expansion
• PTFE inner core for superior pressure resistance and consistent brake performance
• Clear abrasion-resistant PVC coating protects against chaffing and corrosion
• Ideal for daily driving, towing, off-road, and performance applications
• Improved pedal feel and brake response compared to factory rubber hoses
• United States DOT approved for street use and safety compliance
• Banjo bolt and copper washers included (where applicable)
• Mounting brackets included (where applicable)
• Direct-fit design for easy installation

The R1 Concepts rncHSK-74027 Stainless Steel Brake Line Kit is engineered to improve brake pedal feel, hydraulic response, and long-term durability on select Audi, Volkswagen, and related applications. Designed for the front braking system, these replacement brake lines use a PTFE inner core surrounded by a high-strength stainless steel braided weave. This construction helps minimize hose expansion under high hydraulic pressure, supporting more consistent braking performance during daily driving, towing, off-road use, and spirited street driving.

An abrasion-resistant clear PVC outer coating helps protect the braided lines from chafing, dirt, road debris, and corrosion. Compared with conventional rubber brake hoses, the reinforced design helps reduce line flex and delivers a firmer, more responsive brake pedal. Precision-engineered fittings and included mounting hardware, where applicable, support a secure factory-style installation. The kit is United States DOT approved for street use and is intended as a direct-fit replacement for compatible vehicles.

Fitment includes the 2015–2019 Audi Q3 and 2015–2018 Audi Q3 Quattro, along with select Volkswagen Beetle models from 2012–2019, Volkswagen Jetta models from 2011–2018, Volkswagen Passat models from 2012–2022, and Volkswagen Tiguan models from 2009–2017. Always confirm vehicle configuration and brake system compatibility before installation. This R1 Concepts kit includes one vehicle-specific set of front stainless steel brake hoses.
