Title: IN NEED OF A BRAKE BOOSTER
Post by: duke on September 19, 2025, 15:17:57: I HAVE A 1964 230SL. MY car is at the Mercedes service shop in Indianapolis to have the brakes repaired. They have told me that I am in need of the Brake Booster and the supply line. The service shop in Indianapolis says that none are available thru their sources. Does anyone know where i might be able to locate the Brake booster and supply line?

Make sure your old one, especially the plastic / bakelite parts don't get damaged while handling the booster.

Post by: stickandrudderman on September 25, 2025, 10:39:21: We rebuild them here in the UK but if you do a search on this forum I'm sure you'll find a company in the USA that rebuilds them.

Post by: JedinDetroit on September 25, 2025, 22:29:05: Get it rebuild. I had one rebuilt here in the states a few years ago. Quick turnaround and I don't remember it being outrageously priced. I am sure I can look up the rebuilder if needed.

I don't think this one will work on a 230 / 250 SL.

Post by: Peter h on September 27, 2025, 03:38:13: Yes, for the t52 you need the late bracket A113 435 0440. Unfortunately, it's hard to find. The t52 offered is also just a replica. It's all complicated, I just wanted to point out another possibility.

Post by: mauro12 on September 30, 2025, 10:53:03: Guys What Is the brake booster model for 230 and 250? The t51 or t52 ? I believe that the 280sl has a different type of booster . They are not interchangeable? Do you reccomend a company in Europe who rebuilds these units ? By the way I’ve tested mine and at idle I have a vacuum between 400 and 500 mmhg which should be within specs . I’ve noticed that after replacing last week all brakes components ( discs , pads , hoses and master cylinder, the brake pedal seems to be harder . I don’t know if it’s only a feeling.. any advice is appreciated

What is "the Mercedes service shop"? Dealership? Independent shop? Friends house?
