### Brake Rotor

#### REMOVAL AND INSTALLATION

##### Sentra and 200SX

CAUTION
Brake pads may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

1. Raise and safely support vehicle. Remove the wheels from vehicle.
2. Remove the disc brake caliper assembly and support with wire.

   NOTE: Do not disconnect the brake hose (if possible).

3. Remove the disc from the hub without removing the halfshaft nut and bearings.

   To install:

4. Install the disc rotor to the hub assembly.
5. Install the disc brake caliper assembly and brake pads.
6. Install the wheel and tire assembly.
7. Bleed brake system if necessary.
8. Pump the brake pedal several times prior to moving the vehicle.

##### Altima, Maxima and 240SX

1. Raise and support the vehicle safely.
2. Remove the wheel assembly.
3. Remove the disc brake caliper assembly. Using a wire, support the caliper assembly; do not disconnect the brake line from the caliper.
4. Remove the caliper mounting bolts and remove the mount.
5. Remove the brake disc (rotor) from the wheel hub.

   NOTE: On some rotors there are two threaded holes in the rotor. Two 8mm×1.25 bolts can be placed in these holes. When the bolts are turned evenly, the rotor is pressed away from the hub.

6. Inspect the disc for wear, cracks, runout and thickness; if necessary, replace the disc.

   To install:

7. Install disc onto the wheel hub.
8. Install the disc caliper mount and torque the torque mounting bolts to the following specifications:
   1. Front wheel — torque the mounting bolts to: 53–72 ft. lbs.
   2. Rear wheel — torque the mounting bolts to: 28–38 ft. lbs. (38–52 Nm) for all vehicles except 1995–97 Maxima.
   3. Rear wheel — torque the mounting bolts to: 16–23 ft. lbs. (22–31 Nm) 1995–97 Maxima.
9. Install the caliper assembly to the caliper mounting bracket. Tighten the brake caliper mounting pin bolts to 23 ft. lbs. (31 Nm).
10. Check the level of fluid in the master cylinder. Top off fluid as necessary.
11. Install the wheels and torque the wheel lug nuts to the proper specification.
12. If the brake system was opened, bleed the brake system.

    NOTE: Make sure to pump the brakes and get a hard pedal before driving the vehicle!

##### 300ZX

NOTE: When removing the disc brake rotor it is not necessary to remove the axle shaft nut.

1. Raise and support the vehicle safely.
2. Remove the wheel and tire assembly.
3. Remove the disc brake pad pins and remove the disc brake pads.
4. Unbolt and remove the disc brake caliper, but do not remove the brake hose. Support the caliper with a wire; do not allow the caliper to hang from the hose.

   WARNING
   DO NOT remove the 4 bolts that hold the halves of the disc brake caliper together. Only remove the 2 bolts that secure the caliper to the steering knuckle.

5. Matchmark the disc brake rotor to the wheel studs.
6. Remove the brake rotor by pulling it from the hub.
7. If the disc brake rotor is hard to remove, install 2 M8 × 1.25 bolts into the holes on the face of the disc brake rotor and gradually tighten the bolts. This will press the disc rotor from the hub.

   To install:

8. Align the matchmarks and install the disc brake rotor.
9. Install the brake caliper and tighten front disc brake caliper mounting bolts to 72–87 ft. lbs. (98–118 Nm). Tighten the rear disc brake caliper mounting bolts to 28–38 ft. lbs. (38–52 Nm.)
10. Install the disc brake pads and install the brake pad mounting pins.
11. Install the wheel and tire assembly.
