Stupid brake rotors!
Just brought some new front rotors for my vy ss ute and I got one side done easy as but when I got to the other side the bloody rotor won't come off the hub!
Any ideas? I've hit it a thousand times with a mallet and a hammer and it hasn't moved at all. Have also sprayed about half a can of CRC 5-56 on it but still with no luck. Used the search function but couldn't find anything.
Cheers

Im not 100% sure on VY rotors, but a firm hit, spinning it abit each time should get it.
Otherwise they have two holes normally where you can screw bolts into, to pull them off. Not sure if VY's have that though, but it works similar to a steering wheel puller.

From what I can find on google people cut them off or heat them up but I don't have the tools to do either of those things.
i had the same problem when doing my rotors, i ended up getting a sledge hammer and giving them a tap.
it worked after about 5 or so hits but damn was it a pain as it started getting dark

just keep banging mate, its pretty much all you can do.
The rear rotors have the two holes but the fronts dont.
I changed mine couple of days ago without a problem. There might be locktite between the hub and disk knowing holden lol.
Or their rusted on.
Have you completely removed the calliper from the disk?

Bit the bullet and managed to find the only mechanic shop thats open on anzac day.
He turned the wheel hard right(was the drivers side rotor that was stuck) and hit it once with a ball-pen hammer and it almost came all the way off
Must of had the magic touch or maybe turning the wheel made all the difference. He only charged me $30 and he fitted the new rotor as well.

Glad it worked out for u
Did he clean off the crap that was between the rotor and hub before fitting the new one?
And what was making it stick?

Nah he didn't clean it at all. It was rust that was sticking it.
Hiya Juzdvs.
This may be handy for others with the problem in the future.
I had the same problem but was scared I'd damage the hub if I belted it with a hammer so used a cheap gear puller instead. Took the load off the hub with a metal drift.
Came off with some cursing.

Seeing you now have new discs fitted, it would be worth taking them off before they get a chance to seize on with corrosion like the old ones, clean the hub thoroughly with wet and dry, till the metal is clean, then smear a very thin coating of high temp grease around the hub where the disc seats.
This is an extremely common problem with Commodores and is caused by corrosion build up between the disc and hub, but can be addressed very simply whenever you remove the discs. Cleaning off the crud also ensures the new disc sits correctly against the hub.
Glad you found a workshop that didn't charge a fortune for the work. But I must agree with Calaber, its worthwhile now taking the discs off and cleaning the mating surfaces, and while grease will work I'd recommend an anti sieze compound. Had the same issue on my old VP and similar result.
Just changed the Disc's on my WK Stato had the same prob, was not sure whether to belt them or not, once again this forum came to the rescue, suffice to say job done & all is well
Thanks guy's & gals
I had same problem on my VS - the trick is to belt them hard with hammer once, then rotate a quarter turn, and repeat about a hundred times until the rotor comes off. I did ruin a hammer this way because I was hitting so hard though - needless to say if you have to remove the rotors this way they will be rooted and need to go in the bin.
maybe just hit it on the other side?
idk maybe you did that but yea happens to allcommodores.
First most noticable when even the whole wheel is a prick to get off.
