In our latest 78 Royale. That we got in 2015. I've rebuilt, replaced, or updated everything that can be rebuilt, replaced, or updated. I've even cleaned/painted the bottom side. Replaced a nice awning with a new one. Then widened the entry door by 7 inches. The only things that I haven't done is Ken Hendersons electric wipers. ( Thinking about it) And going to 6-wheel disc brakes. So. Now what should I do?
Back in 2005. I got some rear disc brakes off of a Tornado. And a Eldorado complete. Drilled the holes that needed to be done. Blasted/painted, Then put them on the shelf. About 3 years ago. A friend had an extra set of Lee Harris disc. I bought them. Not thinking that I had 2 sets at home on that shelf. (Not bright on my part.)
Now what do I do since I have the parts? The original 4 drums were fine. If you manually adjust them every year. And about no one does that. The ONLY reason that I had ANY interest in rear disc. Is that my GVW ( Gross Vehicle Weight ) runs between 17,000 LBS to 24,000 LBS all the time. And what would happen if my trailer brakes failed. This put me past my Comfort Zone. ( I just don't ever do that)
So, what to do with the extra disc brake set up? I have 80mm front. 78?mm on the mid axle. Drums rear, And a stock master cylinder up front. With the brake lines switched. I have reservations. As to what I'm really gaining. Other than not having to adjust the rear drums ever year. And getting parts off that shelf.
This topic has been batted around for DECADES. So, what's the latest thoughts. Doing nothing sounds nice. ( GRIN)
