Been fixing up my 78 Chrysler Conqueror after it sat for 2 years so I can put it up for sale and the trailer brakes were in bad shape, so i bought brand new backing plates, they came complete with new shoes, all springs, adjusters, and wheel cylinders. Hooked it all, bleed the brakes, and when you jack up a wheel and manually depress the surge brake housing you cant spin the wheel, so the brakes are expanding.
Yet when you hook it to the car and pull foward a few feet and stop the trailer...
Trailer brake help Surge brakes
