help brakes Just spent all day and a lot of brake fluid on trying to fit twin brakes to the front of my bike. i have a 1994 ducati 600 ss. i got off ebay a 600ss disk and the right hand caliper from a 750ss i also got a twin bolt to fit my master cylinder so i could run two line from it. but after an age of trying several ways to bleed the system the brakes were still very spongy. so i tested each line and each caliper in turn and when i did that they were fine rock solid. so what am i doing wrong, do i need to fit a different master cylinder. i.e one off a 900ss or from a 916. im real ****ed off i through this was going to be a simple job pleases help |
