Anyone know how the rear rotors come off on a 84 gsl? Factory service manual isn't clear

 

This is for the GSL-SE but they are very similar to the GSL.

seems as though they just slide off but there is a lip that it has to fit over i will take pics tonight and post them, do you have to remove the axle bearings first.?

 

nope! you need to remove the screw that holds the rotor to the axle and then it should come off.
unless its rusted. then it'll need some help

 

You may be making the job harder than it needs to be. The rear rotors on disk brake cars are easily slid off of the lug nut studs after you remove the brake caliper and mount (2×17mm bolts). The bolts may be difficult to reach, as a standard box-end won't quite fit and using the enclosed end of the wrench is impeded by the shape of the mount backer. Once those are off, the rotors are held on only with a single Cross-Head screw of coarse pitch that may need an manual impact driver to remove if it's rusted in place. Many are if they've not been serviced or greased to avoid corrosion welding.

Once that screw is out - which is only there to retain the rotor while you're working on brakes - the rotor slides right off. If yours is sticking, it may have corrosion behind the rotor to the axle, which you can break loose by tapping the rotor gently on all sides. If corrosion is an issue, you can spread a thin coat of axle grease on the mating parts when you reinstall, which will prevent this in the future. A very thin coat is all it takes. Good luck,
