I`m working on adding a second set of disc brakes to my trailers back axle. The front axle is already disc braked. I have looked into purchasing calipers and rotors and that part seems pretty straightforward on adding to the rear axle. My question is how are the hydraulic lines ran to the new calipers. Are the back calipers fed from a jumper line from the front caliper on each side or are they fed by a " 1 into 4" Tee that I would need to purchase and install replacing the current "1 into 2" Tee split from the main hydraulic supply line? Any help would be appreciated.
