1977 240d Brake pedal hard no travel
I have a 1977 240d The brake pedal has gotten hard to push over the last three days. Now I cant press the pedal at all. I checked the brakes at the wheel and the all look fine. I checked the master cylinder but the fluid level looks fine. I checked the booster and there is very little vacuum on the line, Could this be the problem. Is there a certain amount of vacuum that needs to be on there. Also is there a way I can bypass the vacuum on the booster to see if this is the problem.Am I chasing my tail is there some other avenue I should look into. let me know

1980 300td wagon WVO Starting w/STC
Howdy. I'm considering installing a STC conversion to my 1980 300TD wagon, but have a few questions before I do so. When you are running on WVO with the STC 1000 and all the upgrades (Boost Pump, Heated Pathway, Heated filter), how does the engine not need to be flushed out with diesel before shutting down to have proper starting the next day.

1977 300D Transmission identification
I’m trying to identify the transmission model in an early production 1977 - 123 - 300D? The transmission has no vacuum lines running to it only electrical wiring (driver side) and a mechanical connection (passenger side). The car has been owned since new, so it’s the original transmission.

'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.
