I finally some serious front brake issues resolved on my Monster. It all began when I came out of my driveway and found out I had zilch front brake, dumping the bike on the curb across the street. The bike had about 8000 miles on it at the time. It was soon after I returned from my 4300 mile western loop tour.At Ducati Newport Beach, they bled the lines, but could not get good pressure, so they got warrantee approval to install a new master cylinder. Some 600 miles later the brake lever was spongey again!Back in the shop, it was completely disassembled, reassembled and bled again. Then it sat for a few days--same spongey lever! Finally the shop got approval to replace the lines with a new set that had different fittings with a proper bend exiting the master cylinder and the problem now appears to be solved. Apparently, after so many miles, the bend in the line out of the master cylinder resulted in it developing an air leak. It is likely a recall will be issued.I am thankful to Ducati Newport Beach for their diligence and their persistence in getting warrantee approvals. I finally feel safe again. That's good, as I plan to go to the CLASS All Women's Trackday on April 6 and then to go coast to coast with the Suffragists Centennial ride this summer, Covid-19 willing. Syl S.2018 M8211984 GPz550Sent via the Samsung Galaxy S7, an AT&T 4G LTE smartphone
