After 30+ years in storage, everything brake-related has to be replaced. The brake hoses, however, don't clip on, the end is threaded and thus I assume just needs a nut. But it's 5/8-20 tpi, no such nut exists. Am I missing something? Just when I start to feel like I might know what's going on. Thanks anyone who has ideas. | | | | | Joined: Mar 2010 Posts: 10,272 Renaissance Man | | Renaissance Man Joined: Mar 2010 Posts: 10,272 | What are you referring to as a "brake hose"? Hard lines or soft lines? Which line are you referring to as being threaded? Can you post pics?

The lines they specify use a horseshoe clip to retain the lines to frame brackets. The part numbers I come up with are UP13841 for the fronts and UP4497 for the rear, those are Napa part numbers. If you want to check RockAuto the Raybestos part numbers would be BH13841 for the fronts and BH4497 for the rear. Incidentally all the lines I saw in my catalogue that used a 5/8" thread had an 18 t.p.i. pitch, hope that helps. | | |
