2002-2009 Nissan 350z Brake Job Tools and Torque Specs

By Core Brake Parts Tech Team — Circleville, OH warehouse

A Nissan 350Z brake job needs ordinary hand tools plus three things people skip: a click-type torque wrench, a dial indicator for checking rotor runout, and the factory service manual for your exact year. The caliper bolt and lug nut torque values are year- and caliper-specific, so take them from the factory manual, not from memory or a forum post. Nissan's own brake service bulletin is clear that over-tightened lug nuts, especially from an impact gun, are a known cause of brake judder.

The 350Z was sold for the 2003 through 2009 model years, and it came with two different front and rear brake setups: a standard caliper package and a Brembo package. They use different pads and rotors, so the first job is figuring out which one is on your car.

Step One: Know Which Brakes Your 350Z Has

Look through the wheel spokes. Brembo-equipped cars have the Brembo name cast or printed on the caliper body. Cars without it have the standard Nissan calipers. Pads and rotors are not interchangeable between the two, which is why every part for this car is listed as "with Brembo" or "without Brembo."

Even within one package, part numbers changed during the run. Our own catalog shows two different front Brembo rotors for 2006-2007 cars, the DBA 4000 Series T3 front rotor for 2003-2007 350Z with Brembo and the DBA 4000 Series T3 front rotor DBA42308S for 2006-2007 350Z. Measure the old rotor's diameter and thickness, or match it by VIN at a parts counter, before you order.

Tools for a 350Z Brake Job

• Floor jack and two jack stands. Never work under a car held only by the jack.
• Breaker bar and the correct lug nut socket. Loosen the lug nuts by hand while the car is still on the ground.
• Click-type torque wrench. Needed for the lug nuts and caliper bolts. This is the tool that prevents judder.
• Metric socket set with extensions. For the caliper mounting bolts and any pad retaining hardware.
• Piston spreader or a large C-clamp. To push the pistons back so the thicker new pads fit.
• Wire brush. To clean rust off the hub face where the rotor sits.
• Dial indicator with a magnetic base. To check rotor runout after the new rotor is on.
• Brake cleaner, brake grease and nitrile gloves. Lubricate only the points the manual calls out.
• Bleeder wrench, clear hose and a catch bottle. In case you open the hydraulics or flush the fluid.
• Factory service manual. The source for every torque value on this car.

Torque Specs: Where the Numbers Come From

Three fasteners matter on a 350Z brake job: the caliper mounting bolts, any caliper or pad hardware bolts, and the wheel lug nuts. The correct values depend on the year and on whether the car has the Brembo or the standard calipers. That is why this guide does not print one number for every car. Use the torque table in the brake (BR) and wheel sections of the factory service manual for your year.

Torque matters more on this car than most people think. Nissan's brake bulletin NTB00-033J, which covers every Nissan except the GT-R, names lug nut over-torque as a contributor to brake judder, especially when the nuts are run on with an air impact wrench. Uneven clamping pulls the rotor out of true. Over time that creates rotor thickness variation, which you feel as a pulsing pedal or a shaking steering wheel.

Do it this way:

1. Run the lug nuts down by hand, then snug them in a star pattern.
2. Lower the car so the tire carries weight.
3. Do the final tightening with the torque wrench to the manual's value, again in a star pattern.
4. Re-check the lug nut torque after a short drive.

One number in Nissan's bulletin often gets misquoted. The bulletin says to tighten the lug nuts to 40 ft-lbs while you index a rotor and measure runout. That value is for the indexing process only. It is not the road torque. Use the manual's lug nut value before the car goes back on the ground.

Rotor Indexing and Runout: The Step That Prevents Judder

Nissan's bulletin says to index any new rotor, any rotor resurfaced off the car, and any rotor that has been removed. Here is the procedure in brief:

1. Clean the hub face so the rotor sits fully flat. Rust or debris on the hub will show up as runout.
2. Install the rotor and all the lug nuts, and tighten them to the bulletin's indexing value.
3. Put a reference mark on the rotor and on the hub.
4. Measure runout with a dial indicator about 10 mm (0.39 in) in from the rotor's outer edge.
5. If runout is over the manual's limit, remove the nuts, move the rotor one stud clockwise, and measure again. Repeat until you find the position with the least runout.
6. If the best position is still over the limit, Nissan calls for resurfacing with an approved on-car brake lathe.

The bulletin also warns that a car that sits for long periods can rust on the part of the rotor the pads do not cover. That can cause judder even after the rust wears off. If your Z is a weekend car that sits through winter, plan on rotors as well as pads.

Pads, Hardware and What to Replace Together

Nissan's bulletin says correct installation and lubrication of the pads, caliper parts and hardware is "essential." The shims, springs and clips damp the movement that causes noise. It also warns never to get grease on the pad friction surface. Reuse the hardware only if it is in good shape. Otherwise, replace it with a brake hardware kit.

Replace together:

• Pads in axle sets. Never replace just one side.
• Rotors if they are at or below the minimum thickness stamped on the rotor, have deep circular scoring or radial cracks, or have dark or blue spots. Those are Brembo's own replace-the-disc criteria.
• Brake fluid if it is dark or past its service interval. Use the fluid type printed on the reservoir cap.

For street driving, a ceramic or street-performance pad is the right call. Race compounds like the Hawk DTC-60 front race pads for Brembo-equipped 350Z are made for track use, not daily commuting. On non-Brembo cars, the Hawk ceramic rear pad set is a quiet street choice, and the Hawk HP Plus rear pads suit a car that also sees autocross.

Bedding New Pads and Rotors

New pads and rotors need a break-in to lay down an even layer of pad material. Nissan's bulletin gives this burnish procedure:

1. Drive on a straight, smooth road at about 30 mph.
2. Use medium pedal effort to stop completely, taking about 3 to 5 seconds.
3. Drive at about 30 mph for roughly one minute without stopping, to cool the brakes.
4. Repeat 10 times.

Hawk's street-pad procedure is a little different, so if you install Hawk pads, follow theirs:

• 6 to 10 moderate stops from 30 to 35 mph.
• Then 2 to 3 hard stops from 40 to 45 mph.
• Do not drag the brakes.
• Let the system cool for 15 minutes.

Hawk's motorsport compounds use their own multi-stage track procedure. Brembo notes that the full break-in period runs about 300 km of gradual braking.

How Hard Is This Job?

For someone who has done brakes before, a 350Z pad and rotor job is a normal driveway job. The hard parts are torque and cleanliness, not access. Allow extra time for the first axle, for cleaning the hubs, and for checking runout.

A few things should send the car to a shop:

• A pedal that sinks.
• Fluid leaking at a caliper.
• A caliper that will not release.
• A runout reading you cannot index out.

Nissan's bulletin fixes uncorrectable judder with an on-car lathe, which most home garages do not have.

Frequently Asked Questions

What is the lug nut torque on a Nissan 350Z?

Use the value in the factory service manual for your year, tightened in a star pattern with a torque wrench and the car on the ground. The 40 ft-lbs figure in Nissan's brake bulletin is only for rotor indexing, not the final road torque.

Can I use an impact wrench on my 350Z lug nuts?

Not for final tightening. Nissan's brake bulletin names lug nut over-torque, especially from an air impact wrench, as a cause of brake judder. Run them down by hand and finish with a torque wrench.

Do Brembo and non-Brembo 350Z pads interchange?

No. They are different calipers with different pads and rotors. Check for the Brembo name on the caliper and order the matching "with Brembo" or "without Brembo" part.

Why do my new 350Z brakes pulse?

Nissan traces judder to rotor runout and thickness variation. The usual causes are a rusty hub face, rotors that were never indexed, uneven lug nut torque, or rust from long storage. Clean the hub, index the rotor and re-torque the lug nuts correctly.

Is there a brake recall on the 350Z?

NHTSA's recall lookup for the 2006 350Z shows one campaign, 11E024000. It covers an aftermarket clutch kit, not the brakes. Check your own VIN at nhtsa.gov/recalls for your exact car.
