Rotor replacement

Years and years ago, rotors and hubs, came together as one unit.
That's how they were sold and marketed.
You needed a new rotor, you got it with a hub.
That's how it was, back in the day.
Then back in the 80's or so these parts became obsolete, and you couldn't get them any where any longer.
Then slowly Raybestos started making rebuild kits, and replacement pistons again.
Then wow, whoopee, we can again rebuild calipers.
After awhile rotors came back on the market, and Centric, really cashed in on those repop ones.
Now you can rebuild the entire KH brake system.
Thats why HUBS for the KH brake system are so hard to find, and come across in this day and age.
They were thrown out with the old, worn out rotor.
Who would have thunk it, rotors would come available again, but they would be rotor only.
But it's good that rotors are available.
Good luck, with your brakes.
