Disk thing on back of rotor?

[91five-o]

I am in the process of replacing my wheel studs on my 91 GT. I have taken the rotor off and when I flipped the rotor over I noticed a disk thing that looks like the disk of a mountain bike brake. I was wondering how you remove this disk as it seems like it won't move. Any help would be appreciated?

ABS ring? Does it look like a gear with straight teeth?

If you have 5-lug then it could be that, but other than that I have no idea what your talking about.

Dust sheild on the back of the rotor??

I think it's the ABS exciter ring. He either has a pair of 5-lug conversion rotors off a Mark 7, or he bought a pair of parts store stock rotors that were cross-referenced to a set of 87-88 t0bird rotors with ABS.

ABS ring on a '91, was ABS an option in '91?

Sounds like the dust shield, I removed mine, three bolts.

Do you guys not use the dust shield at all?

The dust shield in the rear is suposed to keep dust off the front end parts and keep water off the rotor, but I clean my car a lot and the dust shield also shields airflow off the rotors preventing them from cooling as well.

I have no dust sheilds on my car, front or rear.


Also, no ABS was not an option in '91, but like i said, our front rotors cross reference with the front rotors off a 87-88 turbocoupe which did come with ABS. Sometimes when buying parts store rotors, they use 1 rotor for everything

I do believe it is the abs ring. It is inside the back of the rotor covering over the back of the wheel studs. It looks like a disk with lots of slots cut out of it.
