Need Help Bad! 1989 Nissan sentra Rotors

ok so this is the thing. there is a large bolt on the outside of the rotors in the middle. I was told to take that off. the problem is I don't know what size of socket to use. I know it's mettric but I don't want to spend a forton on a set that i only need one socet from. the cheepest one is like $300.00 and i really can't do that with all the work i have to do on the car. can anyone help me get this fixed?

$300 for a socket? Is this this platinum or gold? It's probably a 30mm, but I'll check my books.

Wire, this vehicle has front rotors, and rear drums.

Ok no it's not a $300 socket just the set of sockets that has a variety. And it's the front rotors that I'm doing. and thanks I just need the right one before i buy it. Money is tight right now.

I'm pretty sure it's a 30mm. Autozone has let me "borrow" the socket(s) a few times. You can ask them if they will let you do this.

the big nut in the center typically holds th cv axle in place and does not need to be removed to replace the brake rotor. You should only need to remove the caliper and caliper bracket then the rotor should slide off.

Yeah, I still have the 30mm from my '89 Sentra and I paid too much for a black socket that can withstand impact wrench use.

You can measure the circumference of this hex nut by wrapping it with a narrow strip of paper, marking lines on the paper, measuring the distance between the lines, looking up the formula for the circumference of a hexagon and the formula should tell you distance "across the flats." This method might be accurate to 1 mm.

Same method for measuring the diameter of trailer tow balls.

Who needs a micrometer?
