These lines are very well made with a nice smooth finish and quality fittings. I really appreciate the fact that they are DOT approved. I ordered them (part number 950.42013) specifically to use Z32 300ZX front brake calipers on an S13 240SX. Kit includes (2) new bleeder caps and (4) retaining spring clips. The installation was spot on with plenty of steering play. I could see that they are inconvenient to install when the calipers are on the car as you have to scroll the entire line. Fortunately, the brake calipers were removed from the car.
