"bigger" Master cylinder

[Lietuvis]

Hi,

I have made BBK to my e30 325i, but the brake pedal is soft. Want to put "bigger" MC. So, is it the same like from e32 750i/L (m70) and e32 730i/735i (m30)? diameter 25mm? Because in realeom code is the same 34311156643. And its enaught only MC or should I put bigger brake booster also from e32?

Thnx.

The e32 mc is a different mounting style than regular e30. So to swap it you will have to use the e32 booster. There are swap threads that show how.

I prefer to use the e34 mc because it is a 25/22 staggered mc. It is the same mounting style as the e32 so use the e32 booster with it.

I just did this on my car with larger brakes up front and stock rears and I like it.

Today I bought MC with booster from e32 735i, will see how it teak and fit.
