'85 300TD why sudden rear braking ??

This is a new one on me...I just bought another W123...and after the second real drive for any miles..I heard a noise in the back the sounded like a cable wrapping around something...then the right rear wheel locks up...then lets go. My kids were 15 miles behind me, so I pulled over. We assessed the situation and the noise was coming from the right back wheel....clank, creak, clank at slow speed. I thought it was a CV shaft falling apart or the parking brake drums, but it was from the wheel area. But, the rotor still looks good on the outside.

Yikes...put in DOT 3 brake fluid! Suggestions ??

Yikes! I didn't realize the W123 uses DOT-4 and I've been using DOT-3. I have only topped off on DOT-3 (about two ounces, maybe 3 between two cars that were a little low), not bled and filled...so...the question...can I just bleed out and refill w/DOT-4? Or would it better to vac out the resovoir, put DOT-4 in and then bleed/refill. The brakes on one have been getting worse after sitting overnight...the first stop is an adventure if I forget to pump once before stopping (goes to nearly to floor).

Thanks a bunch.

81 300SD transmission seals are leaking ??

My transmission has developed a leak at the front seal. How difficult a job is it to perform as a DIYer? What other seals should be replaced at the same time? If out of the range of DIYer, what would be an estimation of how much professionals would charge? Is this something one could expect a local Aamco could perform correctly? Thank you in advance for your response.
