parking brake nut?

[iruyle]

I have a '72 FJ40 and I need to get into the P-Brake rotor to reattach my cable...
My largest socket is 25mm and it's not even close. Anyone know what size I need?

Thanks.

I just took mine apart and a 1 1/8 standard worked just fine.

I think it's either a 27 or 29mm nut,... it may take a decent impact wrench to get it off, depending whether or not it has been removed before... if it has the flange bent into the grooved output shaft, you will need to use a flat punch to "unlock" that locknut.
