Removing front disc from rotor?

[jangell]

I’m doing the DMC UK Big Brakes upgrade. I got the hub/rotor assembly off the driver’s side without issue (the wheel bearings disassembled themselves as expected), but I’m not sure hit to get the hub off the rotor. I don’t want to risk damaging the hub by hitting it with a hammer too hard. I guess I can clamp the hub somehow so I can hit the rotor? Any tips for getting the rotor off?

Thanks!

Use a block of wood to cushion the impact or use a rubber hammer.

I'd also put the rotor down so the hub is between two items, like the stack of pallets/wood you have in the background, and hit the hub downwards between the gap. If all else fails, use heat on the rotor.

So, directly into the hub bit in the center of the second photo (the one showing the bake of the rotor), then? I’ll give it a go.

One more question: is the disc in the middle of the spindle in this picture part of the bearing that I also have to remove? I removed the dust shield and just noticed that but was still there. Just want to make sure I get everything.

Thanks!

Recheck my first post, I edited it to include more info. Also, that is a spacer in the photo and can be left there (part #100025).

The block of wood and a 4 pound hammer was the key — thanks again!

Now off to the parts manual to see if that disc on the shaft is part of the bearing or not.

It is just a spacer essentially. You can leave it on. It is not part of the bearing.

Excellent — because it really didn’t want to come off. :)

It is best to just leave it alone anyway, I've had these break trying to remove them in the past.
