I was trying to replace my brake rotors and pads, but I stripped one of the two screws holding the rotor to the hub. Any suggestions as to how I can take it out without having to replace the knuckle and everything?

tapp or torch?

Use a drill. The screws just hold the rotor on while you work with the caliper off. Not using them doesn't cause a problem, I don't use them because the screws never come out and I'm sick of dealing with it. The wheel holds the rotor in place and aligned.

drill off the head of the screw and use vise grips to take the rest off once the rotor is out of the way.

what u can do is there is a tool for stripped screw heads which is the shave of a square and u can do that to take it out

An impact driver would be best (hit it with a hammer to operate) a good mechanic may have one or you may be able to rent one. Craftsman makes a 3 piece philips extraction set but I don't know if that would do it. Probably you should just drill the head off.

I tried to get those out on my 05 and they are stuck already. I was going to try to lube them to prevent this from happening when the pads need changed.

****, i did the same thing.. i was turning it the wrong way. You prob didnt just strip the screw but messed up the threads. The metal used to make the screws is very soft, best thing to do is go to a machine shop and get them to tap in a new hole. It cost me $30 cnd and it was a lot better then going to the dealer and getting new parts.

That's good to know. I rotated my tires two weeks ago and when I took off one of the wheels, both the screws in my rotor fell off. One I screwed back all the way, but the second was stripped, so I just semi-put in in, but left enough for me to hand unscrew.

****, i was thinking of a diff screw
Um.. once u get the screw out i hear that it doesn't really matter if have it. Apperantly its just there to hold the rotor on during the assembly process.

No, they do more than hold the rotor on during assembly. The screws align the rotors to ensure it is concentric. The lack of these bolts will not result in catastrophic failure of the braking system, but may result in vibration due to lack of concetricity.

The rotors are hubcentric, the screws serve no purpose other than to hold the rotor in place when the brake caliper is being installed. I do on average prolly one brake job a day that has these type of screws that hold the rotor in place. And to this day after 19? years iv'e never had a brake job come back for a vibration with this being the cause. I dont recall ever seeing a rotor that wasn't hubcentric that was a slide off rotor!

No matter what anyone says, you need an impact screw driver. You can prob retread the screws also with an impact screw driver as well.

tap and die set. first drill a whole into the screw. small one, then go one step bigger, and keep going till the screw itself is hollowed out. then there should be no more screw left. clean up the rest, and order a replacement at a honda dealership. if not this, then use a tap and die to re-thread the threads.

another method i saw on removing these screws is to get a pick, and ram it in the screw and wack with a large hammer. Also make sure to use some sort of penetrating lube to help in the removal of this screw. Then just get some new screws if you are bound of having these screws in.

I did the same thing two weeks ago - stripped the head of the same bolt. I drilled a small hole straight through the entire screw (plenty of clearance for the bit to come through the other end). Then I used a screw extractor. The screw extractor is reverse threaded, so as you are screwing it into the hole, the screw loosens and comes out. A screw extractor set should cost you less than $20. Then I bought a replacement screw from Honda for less than $1.
