Sometimes booster repair kits are available.....
I remember fixing one in the distant past.... I remember talcum powder being part of the process....

Thought I would give you all an update on what all I've done on the 240D.

First necessary repair was the alternator. I assume the seller must have used a charger to charge up the battery, because the alternator definitely wasn't charging. That was a relatively easy repair, and I was glad it was a bad alternator and not a battery, because the alternator was cheaper.

Next up was the instrument panel lights. Based on research I suspected it was a bad rheostat. I took it apart and cleaned contacts, etc., but it still wasn't working, so I soldered in a jumper wire. Having previously owned a '71 250C, I couldn't ever remember saying "gee, I wish my dash lights were dimmer," so I didn't really mind giving up that function.

Finally, today I did the project I'd been putting off, replacing the brake booster and master cylinder. I had been getting along without power brakes. I planned to replace the MC as well, because i suspected it had been leaking into the booster. Then yesterday I lost pressure in the brakes. I think the MC finally gave out. Anyway, the operation was successful. Hardest part was definitely getting the booster unbolted up under the dash. Now we have good brakes!

New tires on Tuesday and that should be it for a while. Meanwhile, my boys are loving their winter car.

THANX for letting us know how it's going .

FWIW , the alternators rarely ever give out m, it's just the voltage regulator and brushes , specifically the brushes that go kaput .

$30 +/- , 15 minutes and you're good to go again .

I just did this to my Brother's '87 300SDL , he wanted to argue and fight it needed more $ thrown at it , in the end I told him " fine ~ I'll pay for whatever it takes to fix it if the voltage regulator replacement doesn't fix it " .

Then I gave him a BOSCH branded V.R. , he slapped it in and VIOLA ! not only was it fixed , it now charges 14 + V.D.C. unlike any other branded V.R. so he's butthurt because I was right .

Brothers , whatare ya gonna do ? .

I look for the BOSCH branded ones on sale and keep a couple handy as I have three old Mercedes that use it as does VW . BMW , Volvo , Saab etc. .
