Hi Folks,

I can use some help here. First time "mechanic" here, and I'm trying to remove one of my rear PCCB rotors from the wheel hub so that I can measure it. I removed the wheel, brake caliper without problem, but for some reason the rotor will not come off the hub. It wiggles a bit, but it appears to be stuck at one of the bolts. Not sure how much force I can use either. Any suggestions are greatly appreciated.

Have you removed the small bolts that attach the disc center to the hub?

Yep, they were on very loose.

I should add that I also have the electronic parking brake engaged. Not sure if that matters though.

I thought so but sometimes it is the easy things we forgets... not sure what to suggest next - too expensive if fail

You can see the blue drum parking brake in this photo.
The parking brake may make a difference on the rears. Take the brake off and see what happens.

When you measure the density of the disc make sure they are on a solid piece of wood to get the most accurate reading. There are three reading points on each carbon disc.

Yep, thats the plan. If I can get the rotor off, I'll be measuring them on Monday. I'll post the results in the other PCCB thread.

Thanks! Once I get home I will give this a shot! Quick question here, if I disengage the parking brake I need to depress the brake pedal. Should I first mount the caliper back on the rotor? I'm concerned I won't be able to open the calipers in the future if they fully close.

Just give the disc a few whacks with a hammer...



Kidding!

It was indeed the parking brake. After disengaging it, the rotor came off effortlessly. Thanks for all the help!
