The APR 15-20 Audi A3 Quattro Rear Brake Hose Kit is a high-performance braided stainless steel brake line upgrade designed to enhance braking response and durability. Constructed with braided 304 stainless steel and a smooth-bore Polytetrafluoroethylene (PTFE) / Teflon core, these lines significantly reduce expansion and flex compared to factory rubber hoses. This results in a firmer brake pedal, less pedal travel, and improved fluid transfer for more consistent braking performance. Fully tested to withstand 3,000 psi, the lines are independently certified as SAE "low-expansion" and meet all relevant safety standards, including FMVSS106 and SAE J1401. The clear PVC outer jacket with red anodized inserts provides an attractive appearance while allowing visibility of the braided lines, and the steel fittings ensure a secure, leak-free connection.

Designed specifically for 2015-2020 Audi A3 Quattro models, these direct-fit brake hoses replace the factory lines without modification. They are compatible with DOT 3, 4, 5 (silicone-based), and 5.1 brake fluids, making them suitable for street and performance driving. The kit includes the necessary hoses and fittings tailored to the vehicle’s specifications, ensuring proper fitment and function. Ideal for enthusiasts seeking improved braking feel and reliability, these lines are a straightforward upgrade for street, track, or daily driving applications, providing enhanced safety and performance with a simple bolt-on installation.
