Front brake rotors

Any suggestions on how you separate the brake rotor from the hub after removing allen screw and two expansion sleeves. Mine just don't want to break free. Have tried pentrating oil and taping
with plastic hammer on back side.

If you are replacing the rotors...

beat them up with a hammer from the inside. Keep rotating the rotor until they get loose. Cruel but, effective. I did it with my car and it worked.
If you want to be politically correct, get a big puller and pull them out. Autozone may have them.
Good luck!

If you don't want to save the rotor (they are being replaced) whack evenly front, edges and back.

Keep in mind not too hard so you don't damage the wheel bearings. I have found hitting the face in the lug nut area works well. Also dribble some pentrating oil around them.

Be sure to use a metal hammer. A plastic one is just too gentle.

I have learned that it isn't how hard you whack it, it is how much. All you have to do is to get one microscopic section to break free.

I was told years ago when I was wrenching and ran up against a stubborn rotor to think it will take 500 whacks to get it off. It came off after about 40.

To make it easier in the future, I suggest using a light film of anti-sieze on the mating surfaces. Anti-Sieze because it takes high temperatures well.

Keep us posted,

Haasman

Thanks to you both, the heavy hammer was the answer. New rotors and pads installed and back in service. Thanks again.

Great! Stubborn rotors can be very frustrating. Be sure and take it easy on the first few brake applications. After a hard brake to a full stop, it is best to let the car move forward just slightly, so the hot pads do sit on one section of the new rotors for too long.

Once the rotors pads are fully seated this isn't so important obviously anymore, but neve a bad idea.

Thanks Haasman for the advise. I always take care in breaking in new pads and rotors so that the pads are not glazed and the rotors warped. I have a few friends who do not heed advise and can't understand why this happens to them.
