I get a slight squealing squeaky lope noise at a specific rotational point from the driver drum area as far as I can tell . It’s only when I’m 2-3mph in a parking lot or mostly faintly heard when making a turn which is weird .
The noise is only at a certain repetitive rotational point when the wheel is turning. So I assumed a warp area rubbing on new shoes .
Yeah, out-of-round brake drum(s) is a good possibility.
The e- brake was adjusted correctly the drum slips on with just enough contact to know it’s not loose or to hard to fit over the shoes .
My e- brake catches a lot sooner then before and it releases just fine I tested that as well with suspension off ground.
When the park brake is released, do all four rear shoes rest solidly on the anchor pin at the top of the brake assembly?
If not, FIX THAT FIRST. The park brake cable is adjusted too tightly, and the service brake not adjusted tightly enough.
I didn’t take to much notice with contact point wear !
I will surely relook this over and consider the new backing plates .
SOME contact point wear is not the end of the world. There can be a point where the wear really does interfere with brake operation.
The worn metal can be replaced with weld filler, then ground flat again. You could dimple it a little like the unworn part of the contact pad, to hold some lube. MIG recommended, but TIG can work, too. Gotta be careful to not heat the backing plate so much that it would warp.
I am planning on little shops rear disc swap
Oh,
HELL NO.
Those bottom-feeder disc brake conversions are bad enough when replacing the 254mm (10") brakes, they're probably worse than what you have now.
If you just have to have rear discs, at least get GOOD rear discs, that have been appropriately sized,
properly engineered, and with a functional park brake.
