Description Reviews These stainless steel brake lines will a perfect replacement line for our Detroit Tuned Big Brake Kit. It will more than likely fit other Big Brake kits that use the same type of fittings. These lines are 24 inches long and makes a 90 deg end with a AN fitting that fit the line and an 1/8 NPT end to screw into your caliper. We also only use OEM bushings on our lines so they stay clipped in their proper place on the shock. Note: The rubber bushing is just placed in the line during manufacturing and needs to be adjusted to make sure the line is routed correctly. It helps to put a bit of lube on the line at the bushing, slowly working it around a bit, pulling back and forth and twisting. Once you get a bit of lube in there, it will slide easy. You need to have the biggest service loop from the shock to the body, with the smallest length from the shock to the caliper, just make sure it's not touching anything and you’re good to go. This can be done for all of the lines, any position on the car, any year. MAKE SURE THE LINE IS NOT RUBBING ON THE WHEEL IN THE FRONT!
