2 piece rotor disassembly
 

Looking for some help on how to disassemble a two piece rotor. Anyone have a photo of the two parts separated? I'm not sure where to apply press pressure to separate - will be easier to restore as two pcs instead of one.

Shouldn't need a press, mine separated very easily once the 5 bolts were out. That took a 4-foot breaker bar though.

Having trouble getting the vision on the breaker bar method?

Impact gun is the way to go.

I was going to suggest that too. That Lynn is a smart guy.

Be sure to assemble the hub and the rotor in the same position as it is a balanced assembly.

Both rotor assemblies with steering arms, backing plates etc still intact had been removed from the car, and as the bolts were seized, I needed some way of holding the assemblies to stop rotation in opposite direction while undoing the bolts. So I used the 4-foot breaker bar as a reaction brace off the work bench, and then the rotor-to-hub bolts could be undone easily.

Yep, still feeling like a dumba$$. The 5 bolts came out no problem, just can't get the rotor separated from the hub. I need to go back out to the garage and stare at it for a while, maybe my dim light will brighten:confused2:

Workin' thanks for that tip - I had no idea.

Victory is mine! Stared at it a bit and said to myself, "self, your a dumbass". Put it in my shop press, gave it a little encouragement and it popped loose.

Not to hijack, but related question- my rotors are marginal on thickness after machining; I've read a few posts here and there about using new rotors (from reproduction 2-piece units) on original hubs. Now wondering about balancing those, following Warren's reminder above..... anyone had that done?

Good question Tim, as I have contemplated the same. The topic has me wanting to offer up a FB ad I could act on myself, but chose not to. There is a complete disc brake with 2 piece rotors and appears to be N44 arms on FB off a 69. What I saw right- steering box, all linkage, including idler arm that looked correct, 2 piece rotors, upper A arms, N44 ( pitman looked short and I did not ask for numbers). Has hard to come by clips on hoses to attach to A arms. Looks like original hoses, too. Wrong: calipers, upper ball joints replaced, everything a little crusty. PM and I’ll try and get you hooked up with seller.

I got the cheap Rightstuff rotor assm. I just used the rotors & my original hubs. If you put 3 lug nuts on the studs it will give you 3 flat areas to put in the vise so you can torque the 5 attaching bolts to 65 foot pounds. Didn't think about balancing. We'll see what happens...Joe

HBC USA made rotor
 

Another consideration.

A few more $$, but this is a good quality USA made reproduction that I used a few times.

Napa used to carry the rotors. The last set I bought was in 2015. They were made in USA (at least it was on the box). Exact as originals too!

I'd even be inclined to check them (or take a light cut) on a brake lathe after all was pressed back together.

I started doing that with front drum brakes to eliminate any sort opportunity for a pedal pulsation.

Thanks Mike, so you used both rotors and hubs? I wonder if they come already balanced.

I used them as a assembly as received. I see now reason to think that they were not balanced. I would be hesitant to use cheaper chine eezz rotors on a driver.

Thanks Mike, would always spend up for quality brake and fuel system parts.

NAPA sold 2 piece rotors?? The only ones I could get were 1 piece replacements.

I ended up buying an NOS set off this site :)
