brake upgrades?

[americanmuscle]

I need to do a brake job, pads and rotors are pretty much done. But instead of trying to just replace the light duty brakes I'm trying to see if I can just upgrade them.

I know with some other trucks you can just swap out the spindles from other cars or suvs with better better brakes. But I don't know if that's the case for these.

My truck is an 84 c10 swb. And I want to keep the 5 bolt pattern.
