Anyone know what size the pistons for the standard front disc brakes on a 200tdi defender 90 is?

is it 46mm?

Only sure way is to measure them yourself, you never know who has been there before.

On a older defender, the only bit I'd always trust as stock and matching the theoretical spec is the VIN plate...

Pre tdi pistons 41mm, just measured one. But as others say only way to be sure is to measure yourself. Just taking a pad out should be enough to do the measure I recon.

I’ve just measured the new OEM calipers I’ve got to fit on my Defender 200tdi. Pistons are 46 mm diameter

Cool. Thanks chaps. You make a very good point. Will just go and measure them.

Yup, the different sizes used are so different that it's hard to make a mistake - 41 versus 46 mm - even just guesstimating with a ruler with the brakes still on the car.
