HarleydocDavidson, the soft braking may also be due to air in the lines or old fluid. You might try bleeding the brakes using Hobbit's overnight brake bleeding technique...once you have parked you bike for the night, 1) use a bungee cord and wrap it around the handle and grip firmly. 2) use a soft rubber mallet and gently tap from the brake caliper, up the hose to the crossover, and then up to the master cylinder, 3) hold the lever and unwrap the cord, and slowly release the lever, then actuate it two or three times moderately, the lever should be further from the grip than before (got rid of most of the air bubbles). 4) Press the lever to the grip and rewrap the bungee securely and leave overnight.
In the morning, remove the m/c cover, check that the gasket "bellows" is flat and fluid is to full mark, repeat step 2) to with the rubber mallet from caliper up to the m/c, you may see bubbles rise in reservoir. Do step 2, holding the lever, but unwrapping the bungee, when you release and actuate 3 times you will see the final trapped air bubbles release and your lever should be nice and firm with good distance between it and the grip. You may do this over a couple days, but the biggest improvement will be the 1st day.
The second method is not so cheap...adding a 2nd disk may not be an option using the stock 'Bob parts, so you may have to find the equivalent diameter forks assembly and correctly spaced triple tree compatible with the steerer tube. Which will require careful measurements of the stanchions, fork tubes and wheels. The Sportsters for example use 39mm stanchions and XL-R models came with dual disk brakes from 2004-2008... I saw a CVO Fatboy that had dual disk brakes with similar hardware, and I am sure that FatBob model as Hobbit elated to could be made to work (who needs mud guards anyway?)...some call my Sporty a "dirt bike" from the XR days, but thats another story. Gonna take a lot of research, but hey if you are going to spend your hard earned cash, honest to gosh research is "peanuts" and ensure it will be done right.
