1984 ford ranger 4 speed. 2wd brake issues

[Derekzee]

I've noticed both of the rear rims were really hot when I last drove the truck. I noticed while down shifting (coasting, no brakes touched, not mid shift) I would have a bang come from the rear. There was a smell at the back by the wheels as well. I don't drive it much, but engage and disengage the parking brake often when I do drive? Seems like the parking brake is the culprit, but just curious if there are anything things I should look for. Or should I just go ahead and pop both wheels off and see how the drums and shoes look? They only have a few thousand km's on them. I should mention that I just drained and refilled the 4 speed transmission. I checked for leaks and it shifted fine, I don't think this is related, but it was the last thing I worked on before driving it.

Taking the drums off for inspection is your first step.

Be sure to look for leakage from wheel cylinders and axle seals.

If they've been hanging up... brake shoes will likely be glazed and signs of heat present on the drums.

Look at the area where the brake shoes meet the anchor pin at the top of the backing plate. The shoes should be full contact with the anchor pin when brakes are at rest. If either of the shoes aren't resting tight against the anchor pin... park brake cables are adjusted too tight or seized in the housings.
