I think the issue is how the hoses are constructed. On factory style rubber hoses the crimped area is part of the fitting but on the braided hoses they aren't. So on the braided hose the small nipple is the only thing holding the hose on and it takes almost nothing to break the nipple.I used stock c5 corvette brake lines. I took broke my lines when using stock gbody lines. No issues. I'm also using kore3 brackets
