I have a 2005 rx330 and I am trying to remove the rear rotors.

Resolved Question:

I have a 2005 rx330 and I am trying to remove the rear rotors. I have gotten as far as removing the wheels & calipers and using machine screws to dislodge the rotors via the two holes but I can't seem to pull either one off. It feels as if a spring or something is holding them on. Am I missing something?

the rotor is getting caught on the e brake shoes, you need to pull the plug and down adjust the parking brake

John, I am having difficulty down adjusting the parking brake on my RX330.

You said to pull the plug. Is that the black rubber plug on the face of the rotor. I have pulled that out but don't see how to adjust the parking brake with a screwdriver or other tool.

I searched the internet for how to adjust the parking brake on the 2005 RX330 and have tried everything I found but I cannot find where to adjust it. (at the wheel, under the car where the left & right side merge, under the dash by the pedal?)

Any assistance that you can provide would be appreciated and I would be willing to pay another $15 for your help.

thanks,

Paul

I also found this on the Internet:

Pull the rotor straight off of the hub to remove it. On the rear rotors on some models, the emergency brake pushes on the inside of the rotor when the emergency brake is applied. The emergency brake shoe needs to be adjusted and loosened so that the rotor can be removed. Locate the small hole on the rotor for inserting a screwdriver. Rotate the rotor so that the hole is on the bottom of the rotor. Shine a light in so that you can see the adjuster for the emergency brake. Insert a flat-head screwdriver into the hole and rotate the adjuster so that the rotor cannot be turned, then back it off until the rotor can spin. Turn the E-brake adjuster it until you can pull the rotor off of the hub


I tried above and can't seem to figure out where the adjuster is inside the hole or what it looks like. When I turn the rotor I do see three nuts each with two raised parallel lines but I can't turn these with a flathead.
