Rear brake disk removal

[jrj512]

I am ready to get the bearings on my rear wheel fixed, so I am trying to remove the brake disk. I have the lug nuts, wheel, caliper, and axle nut removed, but the dang ol' brake disk won't come off. Should I just use some penetrating oil and let it sit overnight? Anyone else know a trick getting the disk off off?

Thanks,
Jerrett

That's the best part. You need a bigger hammer!!!!

There is a tapped hole in the rotor, put a bolt in it and tighten it up. It will pop it off nice and easy!

Or crack the rotor. The hammer is more satisfying!!!

This method worked for me. Bo tried the hammer with no luck while I was digging through my misc. Mazda bolt drawer. Once I found one that worked, the rotor popped right off.

Yes its always more fun when you can introduce a Hammer into a project!

A little PB, couple of bolts, and a tappy tappy with a rubber mallet and Presto. They should come right off.

Well, it turned out there were better issues waiting for me. I'm sure anyone who has done this is probably good laugh by now, but here we go...

While I was waiting for help on the disk, I decided to use the puller I rented from Autozone to get the drive axle free from the hub. Yeah, right. The axle was not moving. I talked to POS Racing about this and he sent me a link to a article on Miata.net (http://www.miata.net/garage/axle.html) that talks about having to use an air hammer to get it out! Not having one, it suggested pulling the whole axle and taking it (with the hub attached) to a shop that does, so that is what I have done now. The whole darn assembly is on my work bench, so now I have to find a place to separate them. Hopefully the guy at the axle place can, but if not, then I'm sure I will find someone. Sigh.

Thanks for everyone's help so far.

A great way to get the rear brake discs is to use the bolt that holds the spare tire in. It'll make a loud pop. Good luck with the repairs.

I soaked it in WD-40 for an hour and THEN beat the out of it with a hammer. Very satisfying only if you're replacing the rotors...





...but don't forget the earplugs...

When Bean and I were swapping my diff the other night, we had to pull the axles. One slid right out, the other didn't. I pulled out the air hammer that came with my compressor tools starter kit. Once I figured out how to assemble it and after Bean stopped laughing from my inexperienced first try, it took all of 15 seconds to pop the axle out. Very cool tool!

Titus was close to putting some speed holes in the side of his car...

Great! Will you be over tonight with it or do I need to wait until tomorrow night?

I really need to get an air compressor some day.

Sure looks like a front rotor to me

[trickyrix]

huh?

The discussion was on rear rotors, but the pic you posted was of a Front rotor.

Ah yes... duh. Well, that's the only one I got a picture of, but all 4 were seized on...

But ya get the idea...
