Audi RS3 Brake Line Kit - Rear - APR - Braided Stainless Steel - Smoked Clear (2017–2020). This direct-fit rear set replaces factory rubber hoses to improve pedal firmness and consistency.

APR pairs a braided 304 stainless sheath with a smooth-bore PTFE core to reduce line expansion. The smoked-clear PVC jacket reveals the braid, with red inserts and durable Cr3+ steel connectors. Application-specific lengths and fittings minimize potential leak points, and each line is pressure-tested to 3,000 psi. Independently certified as SAE low-expansion (0.07 cc/ft @ 1,000 psi; 0.11 cc/ft @ 2,900 psi), they’re DOT-compliant, meet FMVSS106/SAE J1401, and work with DOT 3, 4, 5, and 5.1 fluids. Includes hardware and copper crush washers; made in the USA. Please compare your factory brake line connectors before ordering.
