chances are the calipers on your kart came from the same suzuki donor vehicle
So first check if the RM80 calipers visually match your busted one.

And this sir is why your awesome. I didn’t even catch that he was the one asking about the leaking caliper. Should merge the two so somebody else doesn’t answer weird also.
If I see a pic I can tell you what it is. I was a assistant manager for cycle gear and I’ve had those dirt bikes. And I’ve had the shifter kart style calipers also. So any pic of the caliper will do just fine.
