1984 244dl manual transmission B23F.

I posted a few weeks ago that I had a buyer for my 240. When we test drove it, after a 20-minute ~12 mile drive, the rear wheels were hot and smelly (like hot wiring). I figured something must be dragging in the rear - brakes or wheel bearings, or axle... Something.

Anyway, I took it out today, drove it about 15 miles on the freeway, then about 5 off, and the rear wheels were slightly warmer than the front. When I really stomped the brakes at one point, I had a pretty bad shudder like warped rotors from the front driver's side. It settled down after a few more hard stops (don't think it's related, but it might be). The front rotors are new (<5000 miles).

Short version:
Went out driving, rear wheels were warm to the tough - about 100F. Last time I drove, they were too hot to touch on both sides. When I pull the handbrake while moving, it makes noise - a loud thump/slap - but only the first time after a stop. It still works though.

I have two questions:
1) Is there a way to tell if the e-brake shoes have delaminated or are sticking without disassembling/removing the rear brake rotor? Also, how much work is it to get to the e-brake? It seems unlikely that both would delaminate simultaneously, but maybe I didn't notice one and the other followed months later.

2) Could rusty brake rotors or anything like that account for extra hot brakes? The car sat for about 2 months before being driven when the wheels were too hot to touch.


Cheers!
