What size bolt fits those two holes that are used to help free stuck front rotors?

 

the ones that hold the rotor to the knuckle, or the ones that hold the caliper bracket?

 

Not the caliper bolts. The two holes on the front of the rotor...I need a bolt that would fit in there. So pretty much the rotor to the knuckle...

 

you got me there, mine didnt have those bolts when i got my car. usually theyre phillips screws. sorry i couldnt help but if you do some how take them off i wouldnt put them back on

 

They're just empty holes right now (as they should be), but I can't get the rotors off for the life of me. So I wanted to try using bolt(s) to push them out...

 

If the rotors are no good, try shocking it with a rubber malet. It should release the hold that the rust has on it.

 

yeah tapping one side with a hammer, then tap the opposite side, should free it up. or maybe a few repeats.

 

Been there done that...

I mean I've slapped these things silly

 

maybe kicking them, heat probably fused them together. the holes are probably big enough for 8mm or 6mm bolts

 

Definitely calls for something larger...

 

I think they are m8 in the front. The rears are m6.

 

Use a BFH wack them from behind as you rotate the rotor. Might take a good 5 minutes but they will pop off.

 

apparently hes already "been there done that." to which i wanted to respond, "then man the f up and hit it harder," but ill give him the benefit of the doubt. its just ive NEVER fully failed at getting a rotor off. just took more oomf.
