Does anyone know the thread size for the little pain-in-the-*** phillips head screws that hold the roters on? I have never been successful at removing those little suckers and have always had to drill them out. Well, I need to know what size tap to use and was wondering if you guys have ever had the same situation and if so, what did you do? (like as in how did you remove/loosen the screws)

Thanks again for your time.

I went and bought an impact screwdriver at work for like $25. Works great. I belive the thread size is either 8mm or 10mm. I belive its 8mm but im not sure.

 

I've always used an impact screw driver. You could also try a large phillips screw driver and tap it with a hammer while your trying to turn it.

 

i use a a crewdriver that has a sharp point on it and tap it with a hammer so that it diggs into the screw

 

phillips srew head on a 1/4 in ratchet and socket for the phillips bit

 

couldnt have said it better

 

Yeah, I tried that. I ended up making the bit into a hand drill.

 

Impact driver with a #3 Phillips bit. If the screw is stripped, drill the head off and leave the rest of the stud in the hub. Don't worry about replacing it; it's not important.

No, it rounded the screw head out.

But it's still the wrong tool.

An impact driver is the correct tool.

 

gonna strip it more if its spinning too fast and its already stripped, get a chissel and hammer it out

Do you even know what an impact driver is?

 

i didnt sound like something u hook up to a compressor, I usually can take it off with a big phillips and muscle sorry

 

impact screwdriver

 

impact screw driver
thats what i used to my rotor to be replaced...

 

Hammer and a center punch.

 

yeah dude u definetely want to use an impact driver.
that is(as stated) the CORRECT tool to use.
easiest to use,
it works every time,
I don't see any reason not to!

Just being cocky, because I see the problems everyone else has. It DEFINATLY helps to have all the right tools.

They're only there from the factory to hold the rotor in place during it's journey through the assembly line. Not even necessary afterward. Take them out and leave them out.

Are you sure?? Because my screws were loose for a while and the brakes vibrated like a mo fo.

The loose screws were not the cause of your vibration. The wheel holds the rotor onto the hub and keeps it from moving. If your wheels aren't torqued down properly, you're going to have some more serious issues than just a vibration . . .

The first time I do a brake job on all of my cars, I take out all of the rotor screws and throw them away. Me and rotor screws have a bit of a history, and we don't get along very well. I've never had any vibrations under braking without them.

 

The same thing happened to me the first time I changed my rotors when I wasn't using an Impact Screwdriver. There is a kit you can pick up at any hardware store that does a reverse drill. Basically it drills into the screw as if you were drilling through metal or what other material, then when it enters you switch the drill on reverse and it gets the screw out. I used that and replaced the screw. On my drivers side I opted for an impact screwdriver. Good luck.
