Overheated rear brakes

I drove 15 mi to work, via high way, with e brake partially on. When I got there, the wheel was smoking. I pour gallons of water on them and let it cool down and drove again for about 10 mi. Now I found the brake didn't seems to returned after it's applied, the rear wheels would be almost fully locked after no more than 10 times of braking. The more the brake is applied, the the shallower the pedal gets. So I towed the car back home. What could the heat do to have caused my rear brake to stuck whenever it's applied?

'83 240D Power Steering "Slop"

I've got a '83 240D with Power Steering. Riding down the highway, the steering has quit a bit of play. I'd estimate I can turn the wheel about an inch (5-10 degrees) without any noticeable effect on the wheels. With the car parked and off, if I grab the input shaft to the steering gear box I can turn is about 5-10 degrees before I see any noticeable movement underneath at the control arm. SO I believe most of the "slop" I am experiencing is coming from the gear box and not further down (tie-rods, bushings, etc.). I noticed in the shop manual that there is an adjustment procedure for the gear box. It looks simple enough but shows torque curves through the steering handle travel.

240D Starter Issues

I've got a 1977 240D with a starter that won't turn (or do much of anything) when the key is turned. It will, however, start right up when I bridge the two screw terminals on the smaller cylinder on the starter assembly (solenoid?). I'm not too clear how exactly the starter motor works, so I'm looking for some help on what to look at/for. More, possibly relevant, info: Drove about 150 miles through 100+ degree heat. When I stopped for lunch, car exhibited above symptoms. Banged on large starter cylinder, car started with minimal fuss. After sitting in a driveway overnight and most of the next day, starter wouldn't turn at all (or even "click"). My friend suggested bridging the two screw terminals on the solenoid with a screw driver, and this started the engine right up.
