Brake calliper piston sizes

[kasbatts]

Hi guys, any one know off the top of there head the brake calliper piston diameters front and rear please.

Starting to plan my new brake system and need these to do the math.

I have a RHD car and while it stops ok, the brake feel on these is horrible.
Planing to convert to a e24 or similar hydro booster, powered from an electric pump and accumulator.

Thanks in advance

OK, so no answers, but that's OK as I realized in the weekend while thinking about it, all I need to know is if the brake master cylinder size is the same on the LHD car as the RHD.

Anyone know?

Cheers

Yes,

is the last answer to your question. There were two versions listed in the repair manual.

Early- 23.81 mm

Late- 22.20 mm
