sort of, the rear brakes are still connected to the front. but the front brake only operates the front brakes. most of the factory lines are still there up too the connectors behind the radiators everything else is gone and been replumed. while i have no issues with the front brakes on the left in pic rightside on the bike they are isolated now no long lines to hold bubbles. the rear brake connection other side to the front is a different story. eurowing builders remove the proportioning valves out and direct connect everything. i still have the valves and the long lines on both sides. big issues with bubbles now that i fixed the leaks. if i had the money i would pull the rest of the factory lives and valves. direct connect the rear brakes and have just one line to the front. i believe its having the 2 lines going to the same place and using both valves is confusing the system. this is the way i was told to install it and the only way the lines fit.
added; on the rightside is the front brakes, you can see the caliper line the bent one on the bottom. the 2 lines coming out the top go to the calipers. on the otherside at the top are the 2 feed lines from the rear, they only fit here try it every way possible. the 2 on the bottom go to the calipers. its the top rear lines were im sure the bubbles are collecting. im sure having these 2 lines connected is messing with the proportioning vales which would cause pedel issues. except for the fact i have had a hard pedel, so i know im not done yet. i ran out of fluid, my air bleeder will change all the fluid in a minute. just pulls it through, have to push the peddle though weird.
