It appears the right rear brakes are rubbing as there's a slight vibration above 60 mph, that and the last time I drove it I could smell the super heated shoes and the wheel was too hot to touch. So I looked at it today, and it appears to be manually adjusted only. My question is; Is the return spring on the bottom supposed to have the adjustment wheel in the coils? You can see it's kind of on top of the wheel. And the shoes are mounted correctly, short shoe in the front, long shoe on the back. I backed off the adjustment a little, but in the course of fiddling around with it, I lost some fluid through the wheel cylinder so haven't driven it yet as I will have to bleed that brake. Just curious if the wheel is supposed to engage the spring. Thanks.
