Today i tried to get the rear brake disc out to adjust the parking brake. Unfortunattely i was not able to get the disc off. The rotor sits so tight that it doesnt move at all !
I tried to hammer the disc, twist and wiggle . . . no success ! I dont want to hit the disc too hard, as it is still in good condition and dont want to damage it. I know some people got this problem here before, so maybe somebody found a way to get it out !

Thanks for your help.

This is not meant to be sarcastic.....but is the parking brake off?

We had to pull really hard. Make sure the emergency brake cable is off or loose. I think we ended up placing a piece of wood on the rotor and hitting against the wood with a hammer.

or you can use this shade-tree-mechanic method:



if the bar clamps are tight but the rotor still won't budge, then tap the back of the rotor with a rubber mallet. With the existing pressure - it should pop right off.

AS you can see by the photo above, there is alot of rust... the rotor sits on a hub boss.. if you spray alittle bit of WD-40 between the rotor and the hub boss, if you have a brass or bronze hammer, it would help... the rotor will come off.. it is only rusted tight.. it needs some shock to break this rust... Dont be shy with the hammer...

Jochen

Great idea, thanks guys . . .

And yes, the e-brake was not enganged, and i hanged out the cable at the backside of the brakeassembly.

Mike, I was thinking about some kind of "tool" like you created . . . This will be the next thing i will try.

Great Forum, great ideas, great guys !

Thanks again - that will help.

if you have a torch just heat the rotor around the spindle,just warm it a little to open up the inside diameter of the disk to free it from the hub.

I believe a "real" rotor remover has 3 pry points. But that was too much for this DIY'er to try and fabricate.

Ditto on "Don't be afraid to use a hammer"
When I pulled mine the driver side came off easy and I was expective a fight with some frightening posts I've read on the E Brake. Well it wasn't long before I understood - the passenger side was a real PIA. The rotor finally can - with the E Brake shoes and all. I readjusted the E Brake before putting them back on.
Good Luck!

Guess I've been lucky. I can't count how many times I have replaced rotors and mine come right off. Probably because they're never on there that long.

Good luck!

Use penetrating oil on the rust on the hub.
Take a piece of wood and a favorite hammer leave the car out of gear so you can rotate the rotor. Keep rotating the rotor as you beat on it. By rotating the rotor you will find a weak spot in the "rust weld". Get a lttle angry!

Jochen

Oh man, i WAS very angry . . . and i did that :



well, thanks for all your support. I will try next time when i have the car up on my "little lift" from C5Frederik

After i realized that i will not get the rotor out, i was so frustrated that i just installed a new set of Ceramix brake pads (from NAPA) in the rear - just to make me feel better, and the old ones where really worn. I still had a new set lying around somewhere in the celler (you should always do )

I have a little DIY section on my homepage www.CorvetteC5.de. You can see the installation process of the pads in the rear ! My site is in english and in german, so you can choose your path. Unfortunattely the DIY (in the Technical Section) is at this time only available in german. English will follow soon . . .

Dont forgett to sign my guestbook. You can find it in my Gallery !

Thanks again for all your help.

Take care,

Jochen

BTW, here is the link were i show how to exchange the rear brake pads. Yes, its in german, but the pictures might explain all !

OK folks,

its been a while that i asked you how to do it, and i tried all your tipps. The puller from Mike and heated the center of the disc . . . Nada !

Finally i went to the garage because i heard a grinding noise from the rotor assembly.

They did it this way: Where the e - brake cable is hanged to the lever that actuates the brake shoes, you have to take out the rubber seal. Then you can turn the adjuster wheel and turn it so the shoes diameter decrease. the point was not rust, it was the shoes hanging inside the drum . . .

the noise was the spring that holds the shoes inside the e - brake assembly. The spring was broken and touched the rotor making noise when mooving . . .

Thanks again for all your support !

LITTLE LIFT

Jochen

Well, acctually i use the little lift to get the car high enough to get the floor jack under the rear crossmember . . .
You dont like the little lift ?

Richin Chicago

If it wasn't for quite a few little lifts there would be several cars that would of had short roadcourse days.

Jochen from your post above you seem to imply that the E brake can be adjusted by removing the rubber boot/seal & turning the star wheel without removing the rotor. Is this right or do I misunderstand ?

Jerry

Jochen

Well, i did not see it when they do it, but as far as my dealer said, you can turn the adjuster wheel whithout removing the rotor. BUT to adjust the shoes, you have to meassure the outer diameter of the shoes, so you have to get the rotor off to adjust it the right way . . .
