APR Braided Stainless Steel Brake Line Set - Audi A3 / Volkswagen GTI - Rear
APR builds its brake line upgrades to replace the factory rubber hoses that expand under load and degrade over time. This rear brake line set for the Audi A3 and Volkswagen GTI uses braided 304 stainless steel construction with a PTFE core, giving you a firmer pedal and more consistent braking feel as fluid moves through the lines with far less flex than the factory hoses allow.
This listing covers the rear brake lines for the Audi A3 and Volkswagen GTI. Each line is application specific, built to the correct length and fitting configuration for these models rather than relying on universal adapters, which reduces potential leak points at the connections. Please confirm your exact model and generation using the fitment tab before ordering.
