I just got back from a 600 mile test drive with great brakes. I did have a few issues installing. One of my bogies was 50 thousands different width (thinner) than the other 3 ??? I found some 50 thou stainless flat washers at O`Reillys and shimmed the back block making my bogie thicker. I also had an issue with a wheel cyl being the wrong one, changed it and all was good. Also had the LR drum scrub the backing plate just a little so I relieved the drum with a grinder.
All in it was a straight forward install and I believe if it had been on anybodys coach except mine there would not been any issues. I did install the rear wheel bearing greasers also. On the trip I checked bearing temps and IIRC the rear bearings were running about 10*-15* cooler than before. After I hand packed the bgs and rotated the drum by hand I could hear the bearings rolling, but after filling the cavity with the new greaser the noise went away. Valvoline molly blend.
As far as time. 40 hrs by myself. well I am slow getting back and forth to the tool box, and did have to replace a bit I dulled running too fast, had to track down washers, wheel cyl, new wheel bgs & cups, grind drum, broke off 2 drill bits drilling the last cross hole when I ran out of cutting oil. So about 1/2 the time was not planned. So I figure 20 hrs to do the reaction arms and the grease fittings for anybody else.
I highly recommend both mods.
