I'm looking to remove the rear rotor for the RDX and the rotor is rusted on pretty good. Does anyone know the thread and pitch of the holds circled in red on the rotor?

use an impact driver

or Drill them out with a drill and drill bit.

You dont need them for re-installation.

The holes he circled are for the 2 screws you use to "pop" the rotor off, Justin...IIRC they are the same thread pitch as the rotor screws but I'm not certain.

A block of wood and a sledge/or hammer going around in circles or a rubber mallet have been more than enough to remove from the hub. Then a light sand on the rusted hub surface to ensure ease of re-installation.

^as you can tell, I didnt read. womp womp womp.

i do the same as rockstar, and just pound the rust off.
a few whacks with a rubber mallet usually loosens all the rust.

Justin and Jeremy...just walking around "pounding the rust off"...
ahhh...the college days, where have you gone?!?!

On an old Nissan, even the holes/ bolts were not enough - I used PB Blaster. My Chevy rotors don't have the bolt holes, but PB Blaster, a couple of hours wait, and the hubs just pulled off by hand - whereas pounding with a hammer did not work. You need to get the PB Blaster between the hub and rotor back, which can be difficult - start with the bolt holes.

Use a smear of anti-seize (aluminum type) on the back of the rotor hub when replacing - esp around the center hole in the rotor.

Thanks guys, I pounded the rotor for a good half hour. I found out you need to take out the rubber gromet (#5 in the picture) and locate the star wheel to loosen the drum brakes to release the rotor -_-;

I had read that too but never had to do that for my rears...they came off. I guess you could probably release it in the center console too with the cables.

^I wish we had a center mounted hand op e brake.

I'm assuming it would work, I could be wrong...there's that set of cables with the 14mm nut to tighten up the ebrake pull. Thought maybe dropping that might relieve the pressure? I might be wrong about how that works.
