are the tandem master cylinders stepped bore?
if so what are the secondary bore sizes?

is

.882 for a 140
and
.940 for a 160
correct?


does anyone have the bore diamaters for a 740 abs master cylinder?


what is the piston size for girling front and ate rear calipers?

thanks

The actual sizes are 7/8" & 15/16". Most 164's have 7/8"(0.875") like 140's. The bigger master cylinder gives less travel & less feel.

Hi,
Those are the correct bores for the MC's, they are not stepped.
I believe the front girling piston size is 10.25cm/2(squared cm) for the 142 and 144 and 10.17cm/2 for the 145,(if I am reading my green manual correctly). I do not know the size of the ATE rears, but I believe the girling's are 11.43cm/2 for the 142,144 and 11.33cm/2 for the 145.
I did not realize they would be different for the wagon, but that is what the manual indicates...and smaller?...maybe that increases the pressure per sq.cm?
This is to the best of my knowledge, (which isn't always that much!)
