Brake Rotor Nut

[Jetski]

Got a 92 bmw 325is, e36 and was doing a brake job to it. I want to remove the front rotors but the nut is huge. Does anyone know what size the nut is that holds the front brake rotor on? Thanks,

the rotors are held on by a small 6mm hex bolt. The big nut you are refering to does not hold down the rotor. The hex bolt is located between two of the lug holes. Also you must remove the caliper carrier bracket to take off rotors..

thanks man for the info

no prob, how'd you make out?

the rotor is stuck on and I don't want to runin it by having to beat it off. I tried a rubber hammer but no luck, probably has a little rust build up around the hub, might try a little heat on it to see if that works. I don't want to ruin the rotor since it is still good.

Mine were stuck pretty good as well. I tried some penetrant but it still wouldn't come off. Since I was changing the rotors as well I just beat on them with a hammer.

Spray PB Blaster on that bitch. Soak it real good...Let it sit for like an hour and then hammer it off. It will come off after a few smacks. Why are you taking them off it they are still good?

just wanted to turn them

are you sure you know what you're doing? it's obvious from the 1st post that you were trying to take off the wrong bolt.
