The GKTECH ZN6 FR-S/ ZC6 BRZ stand-alone stainless steel braided brake line kit is designed to be used when setting up a dual caliper hydraulic handbrake kit. These lines go all the way from any selected master cylinder with a 3/8-24 thread to the rear calipers. The GKTECH braided brake lines are assembled by us in-house in Australia using stainless steel fittings, stainless steel braided line with a Teflon inner tube and PVC outer for protection.
