HELP - rotor removal problem!
I have the J55 brakes (heavy duty) and need to turn the rotors but they don't what to slide off the spindle. They such look like they are designed to do so but they won't budge! I just want to make sure these remove just like the regualr brakes before I beat on them to much.
Anybody have any advice?

Re: HELP - rotor removal problem! (Half Fast)
I saw that tech tip but I am still wondering if they changed something on the J55 option. They don't mention the J55.
I just don't want to damage anything beating on the car without being absolutely sure. My manauls aren't due in teill next week.

Fronts, yes.
I put some WD-40 around the hub so I will let it sit a while before try again. I guess it is rusted on a bit. I don't think they have ever been off. The car has 50k miles on it.
Hey, I noticed you have the Corsa exhaust. I would like to hear that!

Now - first off - dont take my word by it - (I dont have the 13" brakes).
But - when I did my brakes on my 93, they were a PAIN!!!!! I beat and beat and beat on them. Tried every trick in the book. Finally - they came off. Then, when I went to get them turned, they just wouldnt cut well. I truly think that mine were warped beforehand, but the beating may not have helped. So - excuse to get new rotors!!!!
If the rotors have been on there a long while, it is possible that they may have somehow metallically rust/bonded. They'll come off, but will take some work.
Doesnt the Grand Sport rotors have some treatment to prevent the rusting at the hub?

Might take a rubber mallet for some persuading. They go through some pretty extreme heat cycles and can be stubborn. Good luck BTW, I'm Slow Vette on Badrap. Speaking softly and building up a "big stick". :D

If the lug nuts are off and the calipers removed, there is nothing holding them but a bunch of rust. It might take forever to soak them with penetrating oil because there is a good bit of surface contact between the rotor and the hub.
I'm afraid the hammer route, as recommended previously, is the only way to go. Sometimes a steel hammer using frequent, but moderate tapping (like a woodpecker) will cause viabrations that will slowly free the rotor. Try tapping for a while then give it a good wack.
P.S. Look for a really good machine when you turn your rotors. The standard tire shop junk will not hold the tolerances that you need to keep 'em from doing the shimmy.

Re: HELP - rotor removal problem! (olephart)
I found the solution!! A mechinic friend stopped by and he beat the rotors hard in between the lug nut area and they came loose!. He said that is only place to safely beat on them.

Re: HELP - rotor removal problem! (ericcer)
Your mechanic was right. The first thing to do when attempting this is do liberally spray around the base of all the lugnuts with penetrating oil. WD-40 is not the right product to use here. Just a bit of trivia, the WD in WD-40 stands for Water Dispersant. It was originally developed for the military to minimize corosion on missle casings.

Ray, thats what it originally meant, but its been improved a lot and has a lubricant in it, as well as rust penetrant and solvent.
Don't be fooled by the name, it does so much more.
