Outer Limits 4x4 Board

Hello... just cruising on ebay today and saw a good deal on a brake booster and master cylinder for Daihatsu, but the seller doesn't know if it's for a Charade or Rocky... so my question: Are the the brake boosters and master cylinders for Charades and Rockys the same? I would like to buy this item for a back up, if it's gonna work, so please, if anyone knows, let me know!
thanks!

I know that Charades even have a number of different brake boosters/ master cylinders depending on the model and engine. You'd really have to see it in the flesh to be sure.
