Novice Bruce here. Restoring 66 sprite. Put new seals in front brake caliper. Bleeding the lines the brakes would not release from disc. Checked the rubber lines from caliper to hard lines, while I could force air through just normal breath I had to blow hard. I assume the line has colasped inside ( look to be the original lines so forty plus years old). When they locked up I could let of most pressure by cracking the bleeder I could turn the disc but there still seemed to be more resistant than I think should be. Question: when brakes released should disc turn without any resistance. Have ordered new brake lines are there any other areas I should check out. thanks Bruce
