The GKTECH Wilwood stand alone SS braided brake line kit are designed to be used with Wilwood calipers in the rear (1/8-27 NPT) and to be used with a Wilwood master cylinder (with a 3/8-24 thread). These lines go all the way from the master cylinder 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. Will suit ALL S/R/Z/A chassis Nissans.
