I just had a round with my 7" brakes on my 2010 Scamp
. I adjusted the "Road" side because when I was giving my Scamp a test run earlier this spring and using brakes, the curb side heated up more than the road (driver) side...apx 107 F vs 98 F which is not bad either way. But, I did as instructed-- tightened the shoes until it locked the wheel then backed off about 5-7 clicks. While pulling, the road side then became VERY warm (Not hot according to Dexter) at apx 124 F-- and this was with NOOO brakes! My hubs have NEVER ran that warm so I knew the shoes must be "dragging".
Here's what I found.... that jarring the wheel, it would spin free as usual/normal. But when I would have the wife activate the brakes with the Tekonsha brake controller lever, they would "bind" again. Finally, I backed them off about *10* clicks. I originally tightened them about 25. They still slightly bound...but just the least jar would free the wheel up. I towed to about 900 miles round trip afterwards with NO problems with the hubs heating.
I just checked a couple a weeks ago while pulling about 80 miles on a trip and the road side now heats up to about 106 F while the curb side is about 5-8 deg F cooler. So I NOW know the road side it "carrying its load" more.
Speaking with Dexter, they agreed that probably, since I adjusted and the shoes are in "new" territory, they're "sticking". But really...I wonder about the "clip" you guys speak of. But since they worked as well as they did on both trips and I'm basically done with long trips this year, I'm not tearing the goofy things down on this 13'er right now in 95+ weather and humidty
