AMS Performance WRX Stainless Steel Brake Lines | AMS.50.01.0001-1

AMS part AMS.50.01.0001-1 replaces the flexible factory brake hoses with PTFE inner lines, a stainless-steel braid, and a protective outer coating. The construction is intended to reduce hose expansion and provide a firmer, more consistent pedal under repeated braking. This kit is only for 2022+ WRX 6MT cars with the standard brake package. AMS explicitly excludes SPT/CVT cars because the rear electronic-parking-brake plumbing differs, and it does not fit TR or tS Brembo-equipped models. Installation opens the hydraulic system, so every connection must be torqued and checked for leaks before the brakes are fully bled with suitable fluid. This is not a substitute for fresh fluid, correct pads, or proper brake maintenance.
