Are there any better calipers I can put on my xb not a big brake kit but something off of another car I can use?

 

If you are looking to upgrade your braking performance, start with better pads, stainless braided brake lines and better brake fluid. If you still aren't happy (I would be surprised) than you can start looking to swap calipers and or big brake kits.

 

I have done brake pads I just ordered new rotators and im going to do the lines but I want more then one piston

 

What are you looking for? Better braking performance or looks?

edit -

Whoops, just saw you posted above me.

And they are rotors, not rotators.

 

both but more on the performance side

 

good brake pads and good brake fluid is just about what you need. the rotors and the brake lines are minimal compared to the pads and fluid. what type of pads do you have? what type of driving/racing are you planning to do? you generally want to match the type of brake pad to the specific driving you plan to do. brake fluid you might want to consider ATE Super Blue or Motul RBF600. the Super Blue by far is better for the value/size of the bottle.
