Brake booster T51/200

Post by einar » Sat 06 Jan, 2018 7:30 pm

Has anyone fitted the brake booster equivalent to T51/200 available at Niemöhler to w111, 1964? See attached picture. I’ve got one, and Niemöhler insist that it fit. However, due to the “spacer-thing” – see arrow, it does not fit into the intermediate flange. The “spacer” can be removed, but then the rubber grommet cannot be fitted properly. Before claiming a return, I would just check if I’ve overlooked something. Any feedback from anyone?

Are you sure Niemoeller is not talking about the W111 coupe?

AFAIK a 1964 sedan always comes with a remote booster (sitting near the headlight)

There are two Diameters of booster, One will fit into the space provided ,and one is larger by 12 mm . The should be a bulge on the inner fender panel to allow it to fit. That spacer needs to be there to hold the rubber boot in place and our RHD cars have a three bolt alloy mount peice to fit the ac accelerator linkage etc. The later finnys have a firewall mounted booster . I cant remember from when but all of the early cars have a booster besides the radiator.

You might be right. Source: Heckflosse.nl:

From 04/63 the 220Sb received disk brakes, and from 08/63 with dual circuit (which is probably when the booster went to the firewall)

The brake booster is mounted on the firewall – as it should be, and also confirmed by Bart. Original part no. is 000 430 55 30 (according to “Teilekatalog”) and type is T51/200. The link shows pretty identical to the one that I need to change: https://www.niemoeller.de/en/w111/w111- ... t51-200-sw
The one I received has the same diameter as the old unit. Plenty of space and no bulge on the inner fender. I suppose that the pre-04/63 is smaller – the remote one placed in the front, next to the radiator. Yes, the “spacer” need to be there to hold the rubber boot/grommet on the booster I’ve received.
However, the one received is the one shown in the picture. “No other option” according to the vendor. Due to the “spacer” (red arrow) it does not fit into the intermediate flange. Is there a variety of this intermediate flange? Attached is a picture on the one in the car.

Job done. Had to grind out the intermediate flange. Not a “big job”. All went very well and the brake booster was easy to fit. FYI :-)

Well done! That would have been my first fix too.
