    I wouldn't doubt they hadn't been changed.

    95% don't change anchor pins if they're stuck, even slightly.

    And pin busings? I've not seen anyone else change since the late 90's.

    Yes, anchor pins wear hard, especially when they quit moving. Always replace, and use anti seize.

    I always called the ones you refer to as “anchor” as “cam” since they are on the cam shaft side.
    I referred to the other side as the anchor. And I have never messed with that side. I don’t know if you even can.
    It might be a “soda” or “pop” thing.
    No big deal just an observation.

    The ones on the s-cam that have retaining clips holding them to the shoes are called rollers, and the ones in the spider with bushes are called anchor pins-at least in Euclid Parts manual. The anchor pins can be removed with a specially designed press like the Tiger Tool I have. 3 lb sledge almost always work for me-but I change them at the same time as shoes. Tiger Tool even has an arbor plate for the bushes around the anchor pins. But I've found it easier and quicker to use a punch tool and sledge and then pop them out.

    I have encountered new and reman linings not riveted square on the steel shoe saddle. They well have a slight kickout on one end like @Rideandrepair described. I’ve had old timers tell me it would happen more often back when it was common to take your old shoes in and have them relined and reuse them on same truck again. I’m guessing the holes would waller out or get drilled oversize to remove the old material so when the new lining was put on it could be a pain to get it straight.

    Boy does that bring back memories.
    As a kid in the 60’s I would help my dad’s mechanic help replace brake shoes all the time.
    You had to take a chisel to knock off the old rivet heads, then punch out the rivet, then drill out each hold so you could put on the new shoe with bolts with screw heads, lock washer, and nuts.
    I can’t remember for sure but there were around 8 or so bolts for each half.
    And all bolts were tightened by hand
    Ah, the good old days…..,

    I bought my trailer brand new 11 years ago. My left front has always been this way. I always assumed that the spider wasn’t installed perfectly (Hendrickson Intatraxx).

    Hello guys. I’m running in the same issue. my top shoe on the trailer is off and i did not change the drum was thinling is good but the top one is hitting the lip and the bottom is lined up but its locking up when i brake. I think if i install new drum it will fix it. What do you guys think ? Btw i replaced anchor pins brake shoe springs scam bushings are good. What do you guys think ?
