Does anyone know where I can get some good front calipers. Mine have been froze up for a while so I was just going to get some new ones and they’re ~$200 each. I can’t find any that will fit that aren’t super expensive.

 

Just checked eBay and there are suppliers of new and used calipers for under $55 each in the US. Kawasakis have just about gone out here in the UK but a regular job when servicing the newer models of Hondas and Suzukis I do work on, is freeing the sliding pins. Remove disc and pads, refit caliper to hub, hit it hard, left & right with a soft hammer, taking care not to damage the pad holding pin hole threads, the caliper can usually be freed off enough to remove it from the pins, remove rust, grease up and re-fit with new rubbers if needed. Check piston isn't seized. If pins on either pads or caliper sliders are well seized, remove all the rubber parts you can and warm the caliper with a blowlamp to free the pins off. All those pins should have been made of stainless, it would only cost a few cents more to make, and stop all this seizing up.

 

The main problem I have is the piston in the calipers are froze up. I tried to at least push them in some to maybe try and get them to move and no luck. I was able to get everything else off except pistons.

 

I shove them in with a Carver clamp and back out using hydraulic pressure from the brake lever, not far enough for the seal to pop out. A small amount of brake fluid on the piston helps them slide in. Can take a few goes to get them free enough. Test is, do they let go of the disc when you release the brake, once assembled?
