I had thia work done by a local and "reputable" shop. The rear brake line fittings have been leaking since the work had been finished. He used JB weld to join the brass T fitting to the two adaptors. It still leaked. He then used AN fittings with PTFE. Its still leaking. My question is, should I try and repair the leak with the current parts that he used as pictured? Or should I scrap all that and use new lines and fittings? I already spent a decent amount of money and want to see if it can be fixed easily. Thanks!
