GB Master Cylinder

[lchilds82]

I was just wondering if the master cylinder from galants with bosters are any different from those with out???? I have beeen told that they are the same. Have the same bolt patern etc....
Anyone have any idea

[Torana68]

they are diferent, not the same, different part numbers, differnet internal parts.

[lchilds82]

But can booster master cylinders be used on non booster applications, what is the part number for non brake booster, are they still available.

[Torana68]

no they are DIFFERENT! they do not interchange and no they are NLA your only chance for a new one is NOS, get yours rebuilt new rubbers are available?

Apart from the fact that they don't interchange, they are also a different bore size anyway.

Also, the disc & drum front brake MCs are different diameters.

You can swap pedal boxes i think to swap between the two.

I have a 15/16' (boosted) running without the booster in my GC.
