    63 rear drum brakes

    Doing my annual inspection of the original drum setup and the fronts checked out fine, the rear - not so much. Memory isn't so hot but I don't recall seeing a shoe crack like this (PS rear wheel trailing shoe). Just crappy off-shore materials maybe ?

    The drums look fine and don't even appear to need "dressed up"..no "checking", no scorched/glazed spots, nada...plenty of "meat" still on them.

    Frank,

    I would look for a NOS GM set and in the near future put them on, It probably won't hurt to leave it until you find a set. The size was probably used on quite a few models of the era.

    Do you recall where the existing parts are from?

    PS, did your wife throw you out of the garage again...

      IIRC the brakes on the car are generic NAPA brakes I put on in 2016 before judging...and I would assume the shoes would have self-arced by now... I don't know of any outfit the "old school" arcs drum brakes any longer.

        I wouldn't be too concerned about it, but if you detect any kind of problem with the rear brakes do another inspection. I've had semi-metallic disk pads loose chunks or material from race track hot lapping, but it had no discernible impact of performance, and I ran the pads to the usual 4/32" thickness before I replaced them. If only street driven I would let them wear to 2/32s, but the less material the hotter the brake fluid gets, so if tracking a car my replacement criterion is different.

        The crack might be thermal related, but I didn't think you ever drove the car very hard. One thing that might be worth doing is taking a something like a dental curette and beveling the edges of the crack down to solid material to remove any loose flakes that might be pulled off in the future.

          Those are not Harbor Freight jack stands in the picture!

          And I always have a floor jack or sometimes two (under pressure) in a critical spot (as shown) even when using quality jack stands...even when I'm not sojourning under the car...
