As the topic title and description says, Im going to replace my front rotors.

The problem is, I have no Phillips screw head to detach my rotors.
I've searched on the forums for DIY and all have the "impact screwdriver" and various sprays to assist in un-tightening them.

There are 4 threaded taps on both rotors, each having something in them that resembles the remains of screws. One of which on the drivers side actually looks like someone tried drilling it out. From what i discovered really irritates me and stumps me.

As bad as it sounds, i haven't replaced all rotors or pads in my 3 years of ownership. They have been inspected every year with flying colors so far. Front pads as of right now is just under 3/16ths pad left. But anyway, issue at hand, how the hell can i get these things off?

passenger side rotor
drivers side rotor

 

I don't know if I can help, but I'll try.

It looks like the screw heads are gone. I would try to gently hammer the rotor off with a rubber mallet. After the rotor is off use some PB blaster and soak the remainder of the screw shafts. wait for 10 minutes then use a needle nose vice grip on the shaft to unscrew it.

That's what I would do. Good luck.

 

Wow just one reply... Ill try it. Was hoping for a few more to try out.. But pretty sure its not a common issue.

 

Oh..... that's not good. There are two screws per rotor that look like they were destroyed. The other two holes are M8 x 1.25. You thread two bolts into them and they push the rotor off the hub.

So... you'll need to figure out how to undo the screws. Good luck!

 

hmm..try this
heat the screws with small torch.
with a chisel or flat screw driver and hammer, tap it counter clock wise.
keep tapping it until screw turns.

 

Nice! I have time this weekend to try that out too. I really need these damn things off, not that it can be a greater issue with them on.

 

^ similar to this idea but better imo:

get a punch and hit the screws/screw heads straight-on to detach the rust inside.
then dont heat them(that will make it swell), but get a chisel, start straight to get it to bite, then start trying to chisel the screw to the left. you'll get it if you follow those steps.

 

An impact is something you hit with a hammer, and its got a bit you can put in. This helps, as many people tend to overtighten these little screws. If that doesn't work, heat helps, and finally, the chisel method always works, but it'll scratch the rotor (no big deal) however that screw won't be usable again.

Remember on a Honda with STOCK rotors on its stock hub, rotor screws are not necessary. No added vibration or brake reduction will occur.

If you get the screws off, those bolts he speaks of can be found in your suspension, usually holding on like a brake hose or e-brake cable, Honda uses these in the suspension to something like that so you can remove it and shove it into the threaded holes. If the rotor is seized to the hub, by tightening them, it threads into the hole, and when it hits the hub, you keep tightening the bolt and the tip of the bolt pushes against the hub to separate the rotor. Cool huh?

I think most knowledgeable mechanics would use an "easy out" or"grabit". Both of these tools are used to extract damaged screws and bolts. You can get them at Home Depot, Lowes and etc. Look them up on Google so you may understand the concept. Also, soak the screw in PB Blaster as previous poster stated but shoot it in fro the back side.

Good Luck.
