318 & 325 brakes, what's the difference and are they exchangeable?

[Korbee]

From what I've read, 318i's come with drum brakes at the back and Disc brakes up front however 325i's come with discs all around? If so changing a 318i's brakes with a 325i's would be an upgrade right?

As you can read I'm quite the noob when it comes to brakes, hence the fact I wanna stick with BMW's parts.

A search on here.....or realoem/bmwfans would have given you your answer 3 hours ago.



Not sure if its 100% the same in Australier, but..

318i's with an M10 (early 318 - ie metal bumpers) have drum brakes in the rear, discs in the front

318i/is's with an M42/(40?) have 4 discs.

325e, 325is, 325i, 318is (91+), 318i(91+) all have identical brake setups. Completely interchangeable.

Early 318s have smaller shock diameters than 325s and later 318s.


Hope that'll help,
Cheers brah....

early 318's (84-85) ran different disks up front than later 325i/e's.

Early 318's AND 325's (85 and under iirc) ran solid front brakes and drum rear brakes, 3 line brake master cylinders, and smaller diameter strut tubes.
