They are separated on a Champion kit.The install instructions detail how to do it.They may still be posted on their site.I have them but not on this computer.I'll try to post when I get on the other one.

California Side Car & Champion both used to put both front brakes on the handlebar using cross over SS lines and rear brakes on rear MC only. I even obtained parts numbers list to do it from CSC located just an hour east over the mountain, but didn't.

My reasoning for not doing it … is I have really good brakes now that I can jump on and not worry about the rear locking prematurely and the trike getting out of shape in an emergency stop … & I have the front brake lever to add to them. If separate, it could get ugly, especially on wet roads.

CSC used a 2 psi RPV and a sugested rebored (larger) master cylinder on handlebar with the front brakes … and had one move the line for rear brakes over to former front brake port on side on rear MC & plug unused rear port. They used some several SS lines & fittings. As best as I recall, the installer sent your front MC in to be modified, I seen no part number for it.

Champion used a 3 psi RPV and stock front handler bar MC & crossover lines to do both front brakes, I think they maybe also used a RPV with the rear brake lines which also got moved to the formerly front port at the rear MC.

Motor Trike just had the front and rear lines reversed on the rear MC. (they specifically state in their manual that the rear MC side or "front" port is 60% and the rear or "rear" port is 40% of the rear MC's capacity)

Lehman … just ran rear brakes off a tee without moving lines on the rear MC. It is how mine is.

I have seen it written in places … like in MT's manual … that the GL1500 rear MC put 60% to the front brake and 40% to the rear most port that feeds rear brake lines. Maybe so, I don't know.

I know my Lehman has rear drum brakes with wheel cylinder for like a 1980 Ford Pinto with 9" drums, they work well. I did add a 10 psi Residual Pressure Valve (RPV) in the rear line to keep wheel cylinder seals full, it lets all but 10 psi brake pressure release when you lift your foot, but drum brakes have return springs and can pull the shoes away from drums. You do not want more than 2 or 3 psi RPVs on disc brakes.

I have considered doing the swap of lines at the rear MC as MT does, just running that left front brake on it but at the 40% rear most port, putting my drums on that side located 60% port, leave the right front on the handlebar OEM, but have not yet done so. My left front rotor does wear faster, it takes a beating I think, (so I picked up extras off a lightly wrecked & parted out low miles '97).

Below is all I have now, and it is like 2005 era stuff.
