Is there anyone as stupid as me?

Update: This shit won't come off until a 4lb sledge hammer came. Whack the heck out of it. FINALLY! Please see the pics, new vs old. Thanks for the help from here, guys. It can't be done w/o your input. XOUTPOST ROCKS!!!

I was doing a simple front brake rotor replacement last night. Got everything out of the way, wheels, caliper, carrier bracket, rotor retaining bolt, etc. Now comes my stupid part: Time to remove the old rotor. It just stuck to the hub and won't come OFF. I tried rubber mallet, hammer, crawl under the car and hammer it HARD. Just won't come off. After making all kinds of noise for over 30 minutes, ya, 30 minutes, I quit! This shit must be soooooo rusted to the hub, I was thinking. Better let the garage to handle it. Next 20 minutes, I put everything back on..........

This morning, I just can't help thinking the whole process in my head over and over again. Suddenly I realized, SHIT! I was SOOOOOO stupid!!!! I forgot one thing! No wonder why it stuck to the hub and not come off.

I'm sure you all know what I forgot...:D

Say what? What does hand brake have anything to do with the front rotors? :dunno:

Small rotor retaining screw, allen head.

I thought you said you removed it in your post? Handbrake wouldn't apply to front wheels. Did you take the car out of gear so you could rotate the rotor as you were hammering?

I hope 30 minutes of sweating it out you didn't damage anything in the hub lol!

LeiZ 08-15-2013 10:22 AM

Are you guys sure handbrake won't affect the FRONT rotors? When I did my REAR rotors, it did affect. So all right, now I'm DOUBLE STUPID!!!!! :bustingup

You got it right, 30 minutes of hammering, seems to knock something loose, :( Now I can feel the wheel has some free play. Dayum!!:hitanykey:

PB Blaster is your friend, i'm sure its just rusted on there pretty good. Spray some PB blaster around the hub where the rotor meets the hub and on the backside too, should penetrate and you can knock it loose.

If you took the caliper off and the retaining screw, that's all you need. Leave the car in neutral so the wheel can rotate as well (not sure if you can do this with an auto, I do it on my stick though), that way you can hammer the rotor all around evenly as you go.

Yeah, you might have forgotten the 6mm retaining screw or it is just rusted on there pretty good.

The handbrake mech work differently on our cars than most cars. Ours is a drum brake design. Where the rear rotors effectively have a drum/shoe set up. Pulling the handbrake spreads the shoes out whereas others have a floating caliper. Where pulling on the handbrake engages the caliper to apply pressure to the rotor. But its all rear, nothing up front.

Check the ring of the hub and make sure you wire brush the crud on there. Then use PB plaster or liquid wrench to have the oil penetrate. If you are going to waste the rotor, rubber mallet isnt gonna cut it, use a hammer or 3lbs sledge. Had the same problem on my 01 4.4 Hub wouldnt come off for anything. Sprayed some PB and used a 3lbs sledge. LIGHTY tapped around to loosen and then just gave it a few whacks to get it off.
