Brake Question

[psaboic]

Hi folks,

Got a question regarding the brakes on my 83 300D. I have a pretty good idea of the answer, but I want to ask the collective experience here just the same.

Driving the car home this evening, it really didn't feel different, but when I got home after a 40 mile freeway drive I got out of the car and smelled something similar to hot rubber. As I walked by the left rear wheel I could feel heat coming off of it. I put my hand closer to the wheel and it was definitely hot.
Not hot enough to seriously burn you, but you definitely did not want to keep your hand on the wheel for any more than a couple seconds. The other three wheels were fine and cool to the touch.

What is causing it? I'm thinking stuck brake caliper. I replaced all the calipers on the car about three years ago but this one could be sticking I suppose. Anything else to consider/check when I pull the wheel off tomorrow (weather permitting). Any tips on the best way to check......I'm thinking visual and feel for dragging on the wheel.

Thanks in advance
