StopTech brake lines consist of a PTFE (commonly referred to as Teflon) inner line that carries the brake fluid, which is then covered with a layer of stainless steel woven braid. The PTFE tube is very resistant to expansion under pressure and will not degrade from exposure to brake fluid.
Every StopTech brake line is 100% tested in-house to a pressure of 4,500 PSI. This is almost 4 times the typical line pressure exerted by a production vehicle’s master cylinder.
Sold as a pair, front lines only.
All E30 (up to 4/91), 1995-1997 750iL, and all Z8s
