Improve vehicle brake performance and feel with DOT-Approved Stoptech?. Stainless Steel Braided Brake Lines. 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.
It's been over a year with these installed on my IS300 and I have no issues. Brakes on a dime instantly. Well worth the money spent and would purchase again for my other vehicles.
