The DFC brake hose is a replacement line for 2018–2021 Subaru WRX STI (rear left). It restores the hydraulic link between the chassis and the left rear caliper to help recover brake fluid flow and consistent pedal response after wear or leakage. Verify the WRX STI year range and left rear location to ensure correct fitment before installing.
