Hi all,
Does anyone know the diameter of the standard front and rear brake pistons?
And if possible the Toyota OEM part numbers for both too.
That's one hell of a question. I reckon someone will have to push out some pistons and measure them.
Out of interest; why do you ask?
51mm front / 45mm rear.

For a second opinion That seems to check out with Budweiser repair kit info.

Glad you like it Carolyn ;)
Its for my Claper refurb small (very small) bussiness i'm setting up for club folk both here and on FB by a club guy.
I have just about finished - equipped the shed / workshop to start.
I'll also be able to do small job powder coating too, (600mm x 900mm max size of the oven) :) 8)
I think the measurements are as said 52mm fronts and 45mm rears, still don't know the oem numbers yet though :-\
Perhaps the supplier of the rubber bit kits will know?
@manos3003 knows. He told me but I forgot
Found his message :)
Front is 50mm,rear is 44.32mm(https://uploads.tapatalk-cdn.com/20180303/ef470032393e22671bc75d78db081549.jpg)(https://uploads.tapatalk-cdn.com/20180303/118063b3925823f9cdb4fdb61fd136af.jpg)
You may be able to find the part numbers on this site?

As my earlier post Budweg, manufacturers of brake calipers and components give fdimensions of Caliper pistons and indicate an EAN number with their parts.
Instantly-recognisable, EAN/UPC barcodes are printed on virtually every consumer product in the world. They are the longest-established and most widely-used of all GS1 barcodes. The EAN/UPC barcode family has transformed the world of retail.
Maybe that is what is wanted, otherwise I have found a visit to Mr T can provide a printed quotation for a component that contains their OE number which may or may not be an EAN number.

With reference to the Amayama catalogue as Topdownman/ Carolyn 's post
the EAN number is NOT the OE part number.
