What's the difference between an E32 750 m/c & a 735 m/c?

I found the front callipers had the same part no. so bagged a set from a 735 for my 635. I took the m/c too but all the how-to guides suggest using a 750 m/c.

Is there a difference?

The 750 has ATE,

 the 735 depending on year

Brake Master Cylinder (Lucas-Girling)
For models with Lucas-Girling brake system only - please verify manufacturer prior to ordering. This unit will not replace ATE master cylinder if so equipped.

Brake Master Cylinder (Lucas-Girling)
This master cylinder has 2 brake line fittings of the same size. If your car has a large fitting in the front and a small fitting in the rear, see 34311162915. For models with production date from 9/1991, this unit can substitute for earlier model Lucas-Girling system

ATE, Brake Master Cylinder
For models with production date through 2/1988

 

If you have such a question, best is you specify exactly the month and year of production. There have been so many changes over the years.

Not sure on the 735's production date though I can probably find out.

The 7-series m/c is to replace the 635's in order to avoid an over long pedal travel. I'm guessing if the 735 piston bore/stroke is the same as the 750 then it won't matter which one I use. However, if the 750 is larger (or the 735 is the same size as the 635) then I'll have to get a 750 m/c.

I know I'll have to get some new brake pipes made up as the m/c connections are on the 'wrong' side for a Highline 635.
