First, trailer brakes don't work. Why: bearing seals leaking onto drums, all four wheels. Fixed that. Put wheels back on ground and test run. EEEK, still no brakes. Replace all four magnets, still no brakes. Found bad splice, Repaired it. Now all magnets work. Have four spare used magnets. About to go for another test run, check underneath first, notice freakin' broken spring on left side of rear axle. All three leafs broken, one old break and two new breaks. Those shackle bolts are tough, especially after being on there for sixteen years! I'll try to get photos up after I get thru with this crap, if I haven't burned it up!!!!
