Good day everyone. I have recently replaced my handlebars and upon completion, I now have no front brakes. During the bleeding procedure, I was able to get one of the two pistons to respond, this confirmed I had internal pressure in the lines and system. I took the front brake caliper off the bike and began troubleshooting. However, I now have no response from the caliper and neither piston moves. I continue to troubleshoot and bleed the brake system getting out all air bubbles but the front brake continues to not work (no movement of pistons in the caliper). I'm fairly knowledgeable about the brake system but am stuck on this issue. I did have to replace a brake line that runs from the master cylinder to the ABS module. However, the line and installation went perfectly and have not found any indication that it may have something to do with the new line. One idea is I might have damaged the front master cylinder during install by accidentally dropping it. No visible damage from fall but I am concerned that it may have something to do with this issue. The bike only has 6K miles and the front brake system has had little wear and tear. PLEASE ADVISE & THANK YOU IN ADVANCE!!
