brakes Touring 250Mm Rear Drum Different Than 320I Drum?

[Slightly Larger Roundies]

Is the stock 250mm drum on the Touring different than the 320i drum that people use on rear big brake upgrade? Do these parts interchange? Thanks!

If it was used with the 2002 hub, it probably wasn't hubcentric on the touring. 

 

But that shouldn't prevent you from using one.  Wonder if the shoe width and position is the same.

 

The E21 part is cheap- order one and see if it works!

 

no help here,

look both parts up on realoem.  if the part number is the same, they you have your answer.

Real OEM only shows the Swedish 230mm part number.

As far as I know, all Tourings (except 1600) had the same 230mm brake drum as the sedans (part# 34 21 1 101 741)..my Touring does anyway.

The Turbo had the 250mm drum (part# 34 21 1 117 047)

Only Neu Klasse & Turbos got the 250mm drums 

2002s all variants (plus 1502 & 1802) got the 230mm *see pic

and 1600-02s got 200mm 

 

If you car has 250mm drums on it now, then a PO has probably done the E21 rear brake swap.

All E21 drums were 250mm also.

Possible my dad did the rear swap and that is most likely the case, however the Haynes manual says Tourings have 250mm drums. Not saying it's correct. here is a photo.

Haynes also shows the 1500-1600 as 250mm, so I think there is two errors on that page.

The info I posted is from the BMW Original Parts Catalogue, which I would believe over Haynes.

 

Have you measured your drums to confirm they are indeed 250mm? Best confirm that, then look for the correct parts.

Yep I have 250mm drums on my car.  Also the Real OEM link shows 2 parts for the 230 and 250mm drums, however the 250mm part # is not listed.  More research needed on my end. 

 

Thanks fellas!

My touring has 230mm drums

My 250mm drums did not have a touring...

250mm part numbers #34 21 1 101 787 & #34 21 1 117 047  -  have been replaced with #34 21 6 752 373.

Which are the same number the E21 & NK part numbers.

So Yes E21 250mm drums will fit.

There are two errors on the Haynes page but what´s wrong with 1500-1600 NK Sedan being described as having 250mm drums? Those cars in fact had 250mm drums.

 

Error 1: Touring never had brakes any different from Sedan with the same engine. 1,6L always came with 200mm from factory, all others had 230mm.

 

Error 2: 1502 had 230mm drums with different wheel cylinders and no 200mm.

 

Regards, Lars.

Thanks for the clarification. New drums ordered.
