Dropped trailer off at dealer yesterday. They said shoes and magnets were fine. Tested electrical and discovered rear axle brakes working fine but the front was not. Found a broken wire. No juice was getting to the brakes on front axle.
My question is even in this scenario shouldn't the rear axle lock up when I had the gain set to 10? It never did. Maybe the 9500 lb TT was too much for just one axle to lock up but I wanted to ask before picking it up tomorrow. tks
Makes one wonder, when testing at dealer, were rear brakes just working, or showing full amps? I have seen trailers brakes wired differently, so depends, on second axle locking on it's own. Some brake wires are just spliced behind front hubs, then added wire to second axle from same splice. In this case, some loss from broken connection, could be passed on to rear axle.
On my current FW, the brakes for each axle are wire independent of each other. Each axle has heavy wire coming down through coroplast for each hub. In this case, I should be able to lock the rear axle brakes, even if the front axle brakes were not working.
While there are lots of ifs/ands with brake wiring, including wire size, plus hub size/shoe size, the Ford IBCs should be pretty standard, one new truck to the other.
