Spiral or a fluted extractor. Soak it in PB Blaster overnight

Do NOT overtighten it; for some reason people thing this holds the rotor on. It's just a set screw to position the rotor.

EXACTLY! This is one of the few screws you can and should add antiseize lube to. And don't worry about it "falling off", cause it can't, the wheel won't let it even if it vibrates loose.

 

if you are replacing the rotor, grab a big hammer and give it a big whack

 

And what, exactly, would that have done, except make alot of noise?

If you are replacing the rotor, and have exhausted the extractor method, cut a slot in the head with a dremel and use an impact driver (the manual kind) to back it out.

Failing that, drill the head off with a carbide/nitride drill bit and back the stub out with a Vise-Grip after soaking/heating.

I've been wrenching on cars for 30 years and I never cease to be amazed by the level of misinformation posted here. It's truly epic.

 

thanks for reply i managed to get them out today good quality allen keys even bought new screws to replace and copper greased them and didnt overtighten them also handbrake works now had to fit screwdriver through the nut hole and turn tooth

 

I once used an oversized torx bit socket and used a hammer to pound it into the hole making a tight fit. Then SLOWLY turned with a big ratchet. This is why I ALWAYS pay the extra $5 for new retainer nuts when I do rotors.

Ya see! That's what you get when your 'torque meter arm' gets miscalibrated and carried away...

 

An option for the future, drill the head off with with a bit the same size as the shank or just a little larger. Don't worry about the rotor, it's being replaced. When the head pops off remove the rotor and use vice grips to remove the remaining portion of the screw.

 

Is there an echo in here? :angel:

 

I like the hammer method best, but I usually go with the scream at it till it backs out on its own will.
