For hand brake, you have to make custom shoes. e90post has most info on this.
- Most make 128i brake shoes larger, it requires cutting 135i shoes in a C shaped cut and attaching to 128i
- it is possible to make 135i brake shoe fit using more parts( 135i back plate pieces). But you will need to add a triangular metal from 128i shoes to make sure 135i shoe catches the Brake shoe pivot point on the rear knuckle
- the previous solution can have welding avoided if you use e46 m3/e60 hand brake shoes direct from BMW( aftermarket cut corners and shave off metal you need). Then one has to file away the metal that is not needed to match the 128i catch point. Potential problem is that e46 m3 brake shoes may be 30mm wide compared to 135i which are 20mm wise. The rotor may have a groove that can have a problem with this.

Andrey; Just to clarify, The e46 M3 shoes will allow the e-brake to work when going from 128i to 135i rear brakes, but I will have to swap out the 128i supporting ring for the 135i part?
I know your post is 4 years old but do you recall if any other parts need swapped, or just the supporting ring?
