Re: when removing the rotors on a 2007 nissan versa,
Look at the rotor on the face of it. some autos have big phillips screws that hold it on, sometimes the factory puts small retaining clips around the lugnuts to hold the rotor in place. if al else fails, yes you need to remove the big nut............WARNING your gonna need an impact tool to put that back on, because it is the driveshaft that is sticking thru there and your not gonna get it to ppull back into place by hand

1Loosen the lugs nuts using the tire iron. Place the wood blocks in front of the tires you will not be removing.
Raise the vehicle using the floor jack. Set the jack beneath the support strut that runs along the outer edge of the undercarriage. Raise it enough to allow the tires to clear the ground. Place the jack stands underneath the same strut as the jack.
Remove the lugs nuts completely and take the tire off. Set these all aside.
Remove the mounting bracket bolts with a socket wrench. The mounting bracket is the metal half-circle that is revealed when you remove the tire. Tie the mounting bracket to the undercarriage with rope to prevent stress damage to the brake line.
Remove the brake pads from the bracket by hand.
Compress the caliper cylinder with the C-clamp. The caliper cylinder is the 3- to 6-inch wide cylinder in the center of the bracket. Make sure that it is flush with the bracket.
Install the new brake pads where the old ones were.
Reattach the mounting bracket to the rotor. Reattach the tire and finger-tighten the lug nuts. Lower the vehicle and the tighten all of the nuts with the tire iron.
Its fairly easy actually just remove the tires. Remove calipers and caliper mounting brackets (when you put the caliper mounting brackets back on lock tite hould be used). and they should be east to hammer off (there may be a little clip on one of the studs holding on the rotor).
Notice: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from it's mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
Remove the brake caliper and brake caliper bracket as an assembly and support with heavy mechanic's wire or equivalent. DO NOT disconnect the hydraulic brake flexible hose from the caliper.
Remove the rotor retaining push nuts from the wheel studs, if applicable.
It may be necessary to strike the end of the hub or the rotor with a deadblow hammer to separate the rotor from the hub.
Remove the rotor by slowly fuming the rotor while pulling the rotor away from the axle.
Notice: Whenever the brake rotor has been separated from the wheel bearing flange, clean any rust or foreign material from the mating surface of the rotor and flange with the J42450 hub cleaning kit. Failure to do this may result in increased lateral runout of the rotor and brake pulsation.
Use the J42450-A to clean all rust and contaminants from the mating surface of the hub flange.
Use the J41013 to clean all rust and contaminants from the inside diameter of the hub section of the brake rotor to prevent any foreign material from getting between the brake rotor and the hub flange.
Install the rotor by slowly fuming the rotor while pushing the rotor towards the axle.
Install the caliper and the bracket as an assembly to the vehicle.
Perform the following procedure before installing the caliper bracket mounting bolts.
Remove all traces of the original adhesive patch.
Clean the threads of the bolt with brake parts cleaner or the equivalent and allow to dry.
Apply Threadlocker GM P/N 12345493 (Canadian P/N 10953488) to the threads of the bolt.
Notice: Refer to Fastener Notice in Service Precautions.
Install the caliper bracket mounting bolts.
For the 15 Series, tighten the brake caliper bracket mounting bolts to 175 Nm (129 ft. lbs.).
For the 25 series, tighten the brake caliper bracket mounting bolts to 300 Nm (221 ft. lbs.).
Install the tire and wheel assembly.
Lower the vehicle.
With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
Slowly release the brake pedal.
Wait 15 seconds, then repeat steps 9-10 until a firm pedal is obtained. This will properly seat the brake caliper pistons and brake pads.
Fill the master cylinder reservoir to the proper level with clean brake fluid.
Remove the tires.
Remove the brake hydraulic caliper.
Remove the brake pads.
Remove the brake hydraulic caliper mounting bracket. Now the rotor is free to be pulled off. If it is frozen on, than a little WD40 at the center hub and a little taping with a hammer will free it.
PS:sometimes there is a small screw that mat be holding the rotor to the hub-- may have to remove that first.
front or rear brake rotor? b sure to shut off the air ride system! the switch is located in the rear kick panel! lift and support front remove tires !the caliper has two mounting bolts remove those and hang caliper to the side using a metal coat hanger! now look at the bracket that was connected to the caliper remove those two bolts !the rotor should come off
After removing the caliper body, unfasten the retaining bolts and remove the caliper mounting bracket, in order to remove the rotor
Use a siphon or clean turkey baster to remove about half of the brake fluid from the master cylinder.
Raise and safely support the vehicle and remove the tire/wheel assembly.
Remove the caliper mounting bolts, then lift the caliper assembly away from the brake rotor.
Use a suitable piece of wire to suspend the caliper assembly. This will prevent the weight of the caliper from being supported by the brake flex hose which will damage the hose.
Once the caliper body and brake pads are removed, unfasten the caliper bracket mounting bolts, then remove the bracket from the rotor.
Remove the rotor retaining screws.
Remove the brake rotor by pulling it straight off the wheel mounting studs or if seized in place, remove the stubborn brake rotor by threading in two 8 x 1.25mm bolts, two turns at a time until the brake rotor is released.
If necessary, completely retract the piston into the caliper using a large C-clamp or other suitable tool as provided in the front disc brake pad replacement procedures in this section.
Install the brake rotor onto the wheel hub and tighten the mounting screws.
Install the caliper mounting bracket and secure with the retaining bolts.
Install the caliper and pad assembly over the brake rotor and mounting bracket and install the mounting bolts.
Fill the master cylinder to the proper level with fresh brake fluid.
Install the tire/wheel assembly and lower the vehicle.
Pump the brake pedal until the brake pads are seated and a firm pedal is achieved before attempting to move the vehicle.
Do not move the vehicle until a firm pedal is obtained.
Road test the vehicle to check for proper brake operation.
remove tire remove both bolts from caliper remove caliper and secure out of way dont let hang by brake line remove both bolts from brake caliper mount bracket located on backing plate remove and slide rotor over hub
