Replace Rubber Flex lines on not
I'm installing a 2001 Chevy S10 Blazer Disc brake rearend that has two rubber brake lines, one for each side. Both lines are in excellent condition no cracks or rub marks, should I replace them now? I would like to replace them but all the replacements are Chinese and I've had some bad experiences with Chinese brake parts, had 2 new Oreillys rear wheel cylinders fail within a month and one brake light switch leak.
Should I keep the original USA lines or use the Chinese?
