New to go karting, need help identifying my kart!

Ok, you may want to soak them in PB Blaster first...

Good Idea

PB Blaster would really help if the pistons/bores are rusted stuck, but the components are prolly all some type of Aluminum alloys and/or Magnesium... So spraying brake cleaner in the inlet ports and outer piston area (and letting it soak) might help dissolve/emulsify that brake-fluid gunk even better.

If the blow gun wont pop the pistons out without soaking, you could certainly try both types of soaking.

Just the answer i was looking for. What dot fluid it takes. Btw! Mbakarts got back to me and and this is their exact words.

"cik from 1996\99 vintage mean

if u need parts send pics"

So i guess they only built these from 96-99?

Yes, I'd translate that reply to mean: Its one of the MBI models that were made between 1996 and 1999

I will give that a try later this evening and see if they free up. Thanks!

You are in the same situation that i was in!
I took my brakes apart and they looked identical to this. I could depress the brake pedal and one or two would pop out but the other 2 were stuck inside pretty bad. I pushed the pistons through the cylinder with a hard plastic punch type thing so i wouldnt scratch/damage the metal and after i struggled with getting the right angle to push through, they popped right out. I took some rubbing alcohol and wiped away all the gunky stuff around the top and they cleaned up pretty good. The seals in the piston were still good, but they were full of white gunky brake fluid from years of sitting in a shed without removing brake fluid i believe. I then disconnected the caliper from the lines and let all the old black fluid drain out of the lines and washed it out with new brake fluid a couple times. I wrapped plumbers tape around all my threads of connecting lines just in case. after i cleaned it all up i connected all the lines and put the fill screw back in and depressed the brake pedal a couple times. all 4 pistons came right out no problem
