Step 8

Step 8: Resurface the Rear Brake Rotors and Replace the Rear Brake Pads.

A. Remove the rear wheels and brake caliper assemblies.

^ Refer to section BR in the ESM for rear brake caliper assembly removal.

B. Inspect! measure the rotors to make sure they are serviceable (they can be reused / resurfacing is possible).

^ Refer to the ESM section BR for brake rotor inspection.

^ Minimum Thickness:
12 mm (0.472 in.)
Any thickness under that: Replace both rotors.

IMPORTANT:
If new rotors are required index them to the hub (see Rotor Indexing).

C. Resurface both rear rotors using the Pro-Cut(TM) PFM Series On-Car Brake Lathe.

IMPORTANT NOTES:

^ The on-car brake lathe is more effective in reducing brake rotor runout than the conventional off-car lathe method.

^ You must use the Pro-Cut(TM) PFM Series brake lathe. It is an Essential Tool and can be ordered from Nissan TECH-MATE.

^ While using the on-car brake lathe place a jack or jack stand under the bumper support bar or trailer hitch to stabilize the vehicle.

^ Stabilizing the vehicle will prevent vehicle wobble that may affect the final rotor runout.

^ Each line on the cut-depth knob moves the cutting tip 0.002 (0.05 mm).

> For the best surface finish and the longest tip life, cut 0.004 in (0.1 mm) on each side with each pass.

> Do Not make cuts of less then 0.004 in (0.1 mm) per side unless absolutely necessary.

> Rotate cutting tips after 7 cuts. Mark the tips so you can tell which tips have been used. Replace the entire bit after all 3 tips (corners) have been used (total of 21 cuts).

> See the Pro-Cut(TM) operation manual for additional information.





^ When using the on-car brake lathe you must prevent metal shavings from contacting or collecting on the ABS speed sensors or collecting in the rear parking brake drums.

^ Remove any shavings that stick to an ABS speed sensor magnet or collect in a parking brake drum. It is best to clean an ABS sensor or parking brake drum with the rotor removed.

^ If the rotor must be removed for any reason mark the exact location (rotor to axle hub) before removing the rotor (see Figure A). The rotor must be reinstalled back to the same location.

^ Do not tighten the wheel lug nuts with an air impact driver. Uneven or high torque applied to the lugs may distort (warp) the brake rotor and hub. This may result in increased rotor runout and excessive rotor thickness variation as the rotor wears.

^ Always use a torque wrench to tighten the wheel lug nuts to the proper torque specification.

D. After the rotors have been resurfaced:

^ Recheck the rotor thickness. Specification: 12 mm (0.472 in.) minimum thickness.

^ Recheck the rotor runout:

Armada: 0.05 mm (0.002 in) maximum runout.

Titan: 0.07 mm (0.003 in) maximum runout.

NOTE:
For Titan; push in constantly on the rotor/axle while checking the runout. This will keep the floating axle in the same place. If the axle is allowed to move (in and out) while checking the runout it will create a false reading.

E. Install the new rear brake pad kit.

^ The new rear brake pad kit is listed in the Parts Information.

^ You'll be reinstalling the old brake calipers.

^ After installation of the Knuckle Slides apply a light coat of Molykote(R) M77 grease-P/N 44003-7S000-to both of them.





^ Make sure to install the outer pad with the spring facing UP (see Figure 13).

^ Refer to section BR in the ESM for rear brake pad kit replacement information.

CAUTION:
Don't get any grease on the friction surface of the brake pad or rotor.
