Brake pads for an Infiniti are not one-size-fits-all: the correct pad shape, friction material, and hardware depend on the specific model, generation, and trim, since Infiniti has used several different brake platforms across its sedans, coupes, and crossovers. Getting fitment right the first time means matching the pad to the caliper design on your exact vehicle, then choosing a friction material suited to how you actually drive it.
Why Infiniti Fitment Isn't Universal
Infiniti's lineup has moved through several distinct brake platforms as the brand evolved - the G35 and G37 coupes and sedans, the M-series and its Q70 successor, the Q50 and Q60, and crossovers like the QX50, QX60, and QX80 that share underpinnings with related Nissan models. Each platform change can bring a different caliper casting, rotor diameter, and pad shape, so a pad that fits one generation of a model will not necessarily fit the next. Trim level matters just as much as model year: performance-oriented trims on cars like the Q50 have shipped with larger, multi-piston caliper upgrades that use a completely different pad than the standard single-piston or dual-piston setup on the base trim. Always confirm fitment against your specific year, trim, and engine - not just the model name - before ordering.
Front vs. Rear: Different Pads, Different Jobs
Like nearly every modern car, an Infiniti uses a different pad front and rear. The front pads do the majority of the stopping work under braking load and typically wear faster, while the rear pads balance the car and, on many Infiniti models, also integrate with the parking brake mechanism. Buying the correct front-specific or rear-specific pad set - not a generic "fits front or rear" part - matters for both pedal feel and parking brake function. For a deeper look at how the two differ, see our guide on front vs. rear brake pads.
Ceramic vs. Semi-Metallic Pads for an Infiniti
Once fitment is confirmed, the next decision is friction material. The two most common replacement options for an Infiniti are ceramic and semi-metallic pads, and each trades off differently.
| Factor | Ceramic | Semi-Metallic |
|---|---|---|
| Composition | Dense ceramic fibers with fine filler material | 30-70% metal content - typically steel, iron, and copper |
| Noise | Quieter, engineered against squeal | Can be noisier under hard or repeated braking |
| Dust | Finer, lighter-colored dust | More visible dust buildup on wheels |
| Heat behavior | Handles high heat with quick recovery | Conducts heat well across a wide temperature range |
| Best for | Daily commuting, city and highway driving | Performance driving, towing, sustained hard use |
If your Infiniti is primarily a daily driver, ceramic brake pads are the more common choice for quiet, clean, consistent stops. If you drive a Sport or Red Sport trim hard, tow, or track the car, a semi-metallic pad built for sustained heat may suit the vehicle better - weigh that against the extra noise and dust.
Low-Copper and Copper-Free Pads: Why the Label Matters Now
Brake pad copper content is no longer just a performance spec - it is now a legal one. California's Motor Vehicle Brake Friction Material Law prohibited brake friction materials exceeding 5 percent copper by weight from being sold in the state starting January 1, 2021, and tightens that limit to 0.5 percent copper by weight starting January 1, 2025. The same law also caps cadmium, lead, mercury, chromium (VI) salts, and asbestiform fibers at trace levels. Because manufacturers do not generally build separate formulations for separate states, these limits have effectively reshaped the national aftermarket.
Brake pad manufacturers now mark compliance directly on the pad: a "Level B" designation means the pad contains less than 5 percent copper, while "Level N" means less than 0.5 percent copper. Akebono, which supplied original-equipment friction material to Nissan and Infiniti for years, states it was the first manufacturer to bring a copper-free OE formulation to a passenger vehicle in North America. The push to cut copper isn't just regulatory box-checking - copper from worn brake pads washes off roadways into waterways, where it is toxic to fish and interferes with their sense of smell, and brake pad wear has been identified as a source of up to half the copper entering urban waterways. When you shop Akebono-brand pads or any modern brake pads for your Infiniti, check for the Level B or Level N marking on the box.
How Fitment Changes with Performance Packages
Infiniti's own parts catalogs make the fitment-by-trim point concrete. On the Q50, for example, the factory upgrade brake package pairs a 380mm, 32mm-thick two-piece front rotor with a 6-piston monoblock caliper, and a 380mm, 28mm-thick two-piece rear rotor with a 4-piston monoblock caliper - a setup built around a Brembo-style big-brake pad shape. The standard-trim Q50 pad package, by contrast, uses a narrower OE-style pad (listed at roughly 152mm wide up front and 105mm wide at the rear) designed around an Akebono-supplied caliper, complete with acoustic wear indicators and anti-squeal shims. The lesson applies across the lineup: before you buy, confirm which caliper your specific trim actually has, because a base-trim pad will not fit a Sport-package caliper and vice versa.
Signs Your Infiniti's Pads Need Attention
Most Infiniti pads use a metal wear tab that contacts the rotor and produces a sharp, metallic squeal when friction material is low - that sound is a deliberate warning, not a minor noise issue. Other signs to watch for: a brake pedal that feels like it travels farther before engaging, a grinding sound (which usually means the pad has already worn through to bare metal and is now cutting into the rotor), visible pad thickness under 3mm when you look through the wheel spokes, or vibration under braking that can also point to rotor issues. For the rotor side of that inspection, see our guide on brake rotor minimum thickness.
What to Replace Along With New Pads
A new set of pads performs best on rotors that are still within spec and free of deep grooves or heavy glazing - resurfacing or replacing badly worn rotors at the same time as the pads prevents uneven new-pad wear and brake pulsation. Replacing the hardware kit (the clips and shims that hold the pad against the caliper bracket) at the same time stops rattles and keeps the pad seated correctly; reusing worn, rusted hardware is a common cause of a new pad job feeling disappointing. Whatever pad and rotor combination you land on, give it a proper break-in period - see our guide on how to bed in brake pads - since the first several stops are what transfer an even layer of friction material onto the rotor face and set how the brakes will feel and sound going forward. For help narrowing down which friction material fits your driving, our guide on how to choose brake pads covers the decision in more depth.

Will the same brake pad fit every Infiniti model?
No. Pad shape and thickness are tied to the specific caliper design on your model, generation, and trim. Always match pads to your exact vehicle rather than assuming a part that fits one Infiniti fits them all.
Do Sport or Red Sport trims need different brake pads than the standard trim?
Often, yes. Performance trims on models like the Q50 have used larger, multi-piston brake packages that take a different pad than the base-trim setup, so confirm your caliper type before ordering.
Are ceramic brake pads a good choice for a daily-driven Infiniti?
Ceramic pads are a strong fit for daily driving thanks to lower noise and lighter dust. Drivers who tow, track, or push a Sport trim hard may prefer a semi-metallic pad built for sustained heat instead.
What does a "low-copper" or "copper-free" brake pad label mean?
It reflects how much copper is in the friction material, now regulated by law in several states. A Level B pad contains less than 5 percent copper; a Level N pad contains less than 0.5 percent copper.
Should I replace the rotors when I replace the pads?
Not automatically, but check them. If a rotor is below its minimum thickness, deeply grooved, or heavily glazed, replace or resurface it at the same time so the new pads wear evenly from the start.
Why does my Infiniti squeal before the pads are fully worn out?
That is almost always the built-in metal wear indicator doing its job. It is designed to contact the rotor and make noise once the friction material has worn down to the point that replacement is due soon.
