More Dust than Rust
Member
Although I've been taking the chance driving it around the neighborhood as it came out of the barn after 30 years of storage, I think it's time to get it to stop properly. Today I took the front hubs off and examined the brakes. Everything looks pretty good and certainly the drums and shoes look good enough to leave as they are given how little I will be driving it.
My question is in regard to the operating shaft, operating wedge and wedge stud. My operating shaft is pushing on the wedge at an outward angle, so much so that over time it has loosened the outer "washer" on the stud. I am assuming that the outer wedge washer should be fixed to the stud. My feeling is that either the operating shaft, bushing, or bore in the king pin is worn, maybe all of them. When I actuate the brakes by hand, it appears that the wedge binds and possibly is limiting the outward force and stroke to the shoes.
I am trying to make this an inexpensive 20/20 driver that looks decent but can be driven around somewhat safely. I will likely be replacing the stud and wedge as they are relatively inexpensive and look pretty universal to PUs and the big trucks but am not really looking to replace the king pins if that is what is possibly worn, any other remedies or tricks?
Also, is it fair to assume that if the rivet heads are still recessed below the lining surface, that I should be able to get the brakes to pretty much lock up once adjusted?
