hey everyone,
would any one know where i can get a caliper kit for a jzz30 soarer? my right caliper has 'seized' and i've been told that i need a caliper ket which has all the seals for it so i can actually brake properly.

yeah i think thats the problem because when i tried to change my pads, the top pin seems to be jammed as in it wont slide in and out easily like the bottom one and i think that is causing the brakes to like shutter or seize? would that be right?

Nah peter i didn't get what you had however i had no brakes i had to double tap the brakes for them to work I thought it was normal till niall pointed it out when he serviced the brakes.The cost was added to the service but around $100 he had to spend a lot of time trying to get it out without snapping the pin(common) it needed to be heated to release.

Same issue here, one of mine has seized up, front passenger side... I pulled it apart today to have a look... The top pin wasn't "stuck" as such, but it amazingly tight. I got it moving a bit more smoothly, however I found after that the caliper was still locking.
Had another look, seems like the pistons/cylinders(what ever they would be called in this case) in the caliper are not going in and out smoothly.
The thing was covered in that much brake dust and grit I'm not surprised it's seized. I WD40'ed the crap out of it and it has freed up somewhat.
So I'm just wondering, what do you guys think another caliper would be worth. And how easy should the pistons/cylinders go back into the caliper?

Caliper kits are about $30 a side from most brake places.
They don't come with the rubber ring that goes on the slide pins though.
I'm in the process of rebuilding some TT calipers before to fitting to my v8. I notice that the slide pins had light gall marks on them from metal to metal contact. There wasn't a lot of grease in them. That was in there was at the end of the slide way and not along the pin.
Anyone wanting to avoid seized slides, check your dust boots for holes the or damage that might let moisture get in and clean the regrease the pins.

It takes about an hour per side if you do it yourself and replace everything. The slide way dust boots are pressed in so getting them out was a pain in the but. If the old boot is ok, don't take it out. Once you get the piston out, replacing the piston seal and dust boot is very easy. The piston might be a bit tight on the new seal. A g-clamp will help to get the piston back in.
If you have to pay to get it done, it'll only be about 1 hour labor if you take the caliper off the vehicle.
Make sure you have the rubber ring that goes on the slide pins (what appears to be part number: 47769).
The aftermarket kit i got for my calipers didn't include these but the brake shop threw a set in.
When these rings wear and break, you end up with metal on metal contact and the slide pin can sieze in the slide way. Rust is the other culprit.
