Power voltage to brakes??

Never been happy with braking on our C Creek. Just installing all new brake assemblies and checked voltage at right rear and it shows only 9.5 volts!!
This is not via the truck. I have it connected directly to a tested 12.6 volt battery .
Should I see that kind of a drop from the battery?

No. Not normal.

Shouldn't have that much voltage drop, I would expect perhaps a few tenths of a volt drop due to wire resistance.

Sounds like you may have severe corrosion at some wire spices.

Or like one of my TTs, it came from factory with three splices between the trailer tongue and the first axle (near as I could tell the factory was using up all of the leftover floor drops on that TT that should have been discarded).. All of the splices were corroded.

You have the option of cutting and replacing every splice or abandon the existing wire and refresh with a much heavier gauge wire.

Typically RV manufacturers will use the lightest gauge wire they can get away with, it works, but due to increased resistance of the lighter wire and distance of the wire it will rob you of brake performance.

I used two pairs of 10 ga wire on my 26ft TT, made a large improvement over the factory 16 ga wire that I found they used.
