98 tropi-cal brake blues- i by passed the 4 parts of the system electric,hydrolic, vacum. i ran the flex hose from the tag to the steel line on the dully axle i just have to test drive to see what hapens, i hope my tag wheel don't lock up
if they do i can add a simple valve an reduce the fluid going back the the wheel cylinders on the tag axle my dully has dule pistoin calipers ( disc ) this all cost me about 50 dollars for parts an took one hr to change an cap off the old lines
