I just have a quick question (actually 2)

1) What is the size of the rear rotor retaining screw (the one which holds the rotor to the hub)?? Is it really needed (my previous cars didnt have any)

2) The head of the screw is a little chewed up. What do you guys recommend doing to remove it??

Cheers

 

1) I don't recall the thread size but it's not needed

2)if it's already chewed up then just drill it out.

To remove them (before messing up the head) you should use an impact driver, it has a screw bit in the end and you hit the other end with a hammer and it generates a twisting motion to remove the screw without chewing up the head.

 

Not sure of the size man, but yes, if it has a retaining screw then yes you will need it. And as for getting it off, sounds dumb but an impact gun may do the trick if it is on that tightly, but if you are replacing it anyhow, then its not really that big of a deal.

 

Yeah, I have an impact driver and for some reason it (or my incompetent hands) screwed the head up trying to use it.

I will probably spray some PB blaster on there and let it soak tonight and head into the garage tomorrow to take care of it.

If it aint needed though, go. I will call home (or advaned) and see if they can give me more details

Thanks for the quick response guys. Well appreciated

 

no, it's not needed.

sure it was on there from the factory but that was most likely to keep the rotors in place while on the assembly line or something. For us though, once you put that wheel on that rotor isn't going anywhere. So that small retaining screw isn't needed.

On my 95 EX when I replaced the rotors I was able to get all the screws out fine so I replaced them and put new ones in. When I did the front rotors on my Civic 1 screw on each side got messed up so I just drilled the heads of those screws and didn't install any new ones.

Like I said, they aren't needed. No need to go through the trouble, just drill the heads of and call it a day.

 

OHHHHHH!!!!! That screw hahaha. For some reason I thought he meant the caliper retaining bolt. No the only reason for the rotor retaining screw is for assembly line reasons. They needed it to stay on firmly and in place so the could do the assembly line brake part a lot easier. And yes and impact hammer works everytime or just drill them out and throw them away.

 

Make sure you are loosing the screw instead of tightern it. Once I had trouble to remove this screw using a impact drive. When I almost gave up and would drill it out, wife pointed out I were tightering the screw. Yes it is right, wife found it out.
