Can Hydraulic Brakes of Demco Tow Dolly be Converted to Electric Brakes
Question:
I have a Demco 2 wheel tow dolly that currently has surge brakes on it that are in need of replacement. I really dont like the surge brake system and would like to convert it to electric brakes. The tongue modification is something I will resolve. My tow vehicle is already equipped with the brake controller. I would need to replace the brake backing plates with the brakes and the wiring for the electric brakes. What more might this conversion entail?

Expert Reply:
Since Demco uses 3,500 drum brake assemblies part # DMSB24429M and # DMSB24428M what you'd need is similar 3,500 electric brake assemblies like the etrailer part # AKEBRK-35L-SA for the left hand side and # AKEBRK-35R-SA for the right hand side.
To wire these up you'd just need 10 gauge wire like the part # 10-1-1 which we sell by the foot. Then to add a 7-way the easiest way to do that is with the 7-way junction box # e99011.

So the problem I Demco, brake part, specifically back plate doesn’t have studs Studs, which will interfere with mounting the spindle flange properly. Are those studs removable?
