i need to get new brake calipers and whats best new ones or rebuild my old ones
Looks like new OEM-style calipers go for ~$90/each whereas a caliper rebuild kit goes for ~$29/side. I went with rebuild kits twenty years ago, and had no problems with them or with the brake system after that.
A third option might be to install good used calipers that don't need a rebuild. I took my stock calipers and rotors off a year ago when I upgraded to a big brake kit - so I'd be happy to sell my old parts at a low price. Let me know if you're interested. Do you want/need rotors too?
