Disk brakes wearing too fast?

I have a 1995 Dogdge Ram Van where the penger front side brakes wear out faster than the left front side. I changed the caliper with a new one and bled all four wheels starting from the fartest side and then eventually down to the front right side. After w few months I check on the pads and sure enough the same thing is happening. Is there a manifold that balance the fluid? If so how do I correct the pressure to be all equal.
