Can an SD brake booster be wedged into a W123?
Yes. But just barely.
Pics coming.

Sorry for the delay.

wow!
what are benefits with the larger volume booster? less pressure on the pedal, more stored stopping power after the engine is off? what was the goal? Interesting swap

I needed a new brake booster and thought... hmmm.... I've upgraded to SD brakes... why not the brake booster as well. What the heck, does it fit?

Let us know how the pedal feel has changed!
Is the fuse box cover still a bear to remove? -J

I'll add a few more pics in a bit. The SD booster is a bit smaller in diameter, but much longer.

Any other changes you had to make? Are you using a 126 master as well? The whole car going to end up that red? That will look quite nice

From astralsilber.de ![]() astralsilber.de - Infos Rund um die Mercedes-Benz Baureihe W123 und mehr... I bought the car as Champagner (Champagne) 473. It'll take a year of two for me to get around to painting the rest. Right now I'm trying to get it on the road, so I've replaced/painted the driver's fender you can see in the picture, the hood, the two front doors and a few other bits in Champagne. That way it'll all match until I repaint to Desert Red.

Glad it's going to be you and not me, if you need to ever replace the vac shutoff valve

That's pretty much the extent of connections to the motor. I pulled it to paint the engine bay and still have to finish putting everything back together. At the moment I'm finishing up the brakes, rebuilt calipers all around (1st gen SD calipers in the front), new hoses, new master cylinder and DOT 5 brake fluid.

What steps are you taking to start using DOT 5?

The brake system is going to be effectively brand new.
I've rebuilt the calipers, reassembling them with DOT 5. The new MC was primed with DOT 5. The brake lines were flushed with Denatured Alcohol and then blown out with air. I was starting from scratch on the brake system to begin with. All four calipers were seized.
