I am thinking about purchasing some SS brake lines, and do have prior experiance with them,had them on two previous Karmann Ghias I own, and worked great. But heard on these new brake systems, hydroboost, pressure system, ect. They don't help as much. Anybody have experience with them on there Tahoe, Yukon, Escalade? Just lookin for personal experience from some people, and how it worked for them. Are they worth the price?
