It is a 2018 TT so I am hesitant about rewiring the whole thing. I will explore the whole system again. I can never reduplicate it without driving hundreds of miles. I appreciate all the suggestions. I thought about replacing the magnet in the suspected wheel first.


Your first post said "2008 TT", never the less if you think these things are made correctly think again. My KZ had one brake wire crimped on the insulation, so only three worked.

Since your controller reported a disconnect, I would think that three brakes working would not cause the warning. Also, a short is probably not the issue.

Have an assistant apply the brakes while you go around and listen for the hum noise at each wheel. If one wheel is silent, that is a good place to start looking. Inspect the brake wiring the best you can. You may have to pull the brake drums off to have a look at the wiring in there too

Start simple and apply some dielectric grease to the 7-pin connection.


Why people do this is beyond comprehension.

Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion. ... The grease does not conduct electricity, so it shouldn't be applied directly to the mating surfaces (pins and sockets) of an electrical connection


Agreed, fix the connection and then if you must, apply that junk.
But dielectric grease has never made a connection better. Nothing works better than a clean, dry connection.

I made a lot of money fixing avionics that had nothing more wrong with them than some av-tech having slathered that muck on the connections.

I had trailer brake problems and found it in the crimps on the wires connecting the axles to the feed from the brake unit.

9times out of 10 it will be the ground for the brakes, check that first! A lot of times the manufacturer will only put one ground per axle, hence causing a problem. I will always ground each brake any more and this usually cures any brake issues. Good luck and happy camping!
