k.. this car obviously needs a ****LOAD of TLC.... It looks like theres stuff leakign in some of the pics... if you want to find out if the fluid leaking is significant you will have to clean those areas up and inspect it periodically. Go to your local pepboys or autozone and get some "engine degreaser". Get the stuff that comes as a foam, you spray it on and let it sit, then rinse it off.... does wonders!
Those BBs possibly came from your passenger side strut hat. The top of the strut assembly on the 240 has a bearing which allows the assembly to rotate slightly as the spring compresses and expands. When that bearing is going out normally the bearing will "pop" under hard braking (as the spring compresses from the weight moving to the front of the car). It appears as though this has gone passed the popping phase and the bearing is completely destroyed. This is what is causing your camber problems as well. Replace the top of the strut assembly and your good to go.
The wire on the battery tray looks like the AC Tank Pressure sensor, doesnt look like you have AC so your fine
When bleeding brakes you should only be using the bleeder valve, just losening the line is not the correct way to do it... if the valves themselves are scared/rusted up, buy 2 sets of russel speed bleeders and replace the old ones, it will make life much easier and youll be able to bleed it correctly.
Also, if a brake/clutch line nut is rounded off, dont be afraid to use the ol vise grips on them.
