2016-2022 Infiniti Q60 Front vs Rear Brakes: What Wears First and What to Replace

By Core Brake Parts Tech Team — Circleville, OH warehouse

On a 2016-2022 Infiniti Q60, the front brake pads almost always wear out first, and the front rotors usually follow. The rear pads and rotors last longer because weight shifts forward every time you brake, but they still wear and should be measured at every inspection rather than assumed to be fine.

This guide explains how the front and rear brakes on the Q60 split the work, what each end looks like when it is worn, how the sport brake package changes the parts you buy, and what to replace together so the car stops straight and quiet.

How the Q60 Front and Rear Brakes Share the Work

The Q60 uses disc brakes at all four corners. When you press the pedal, hydraulic pressure pushes the caliper pistons, which clamp the pads against the spinning rotors. Infiniti describes the system simply: the calipers press the pads against the rotors, and the resulting friction slows the car and gradually wears both parts.

The front and rear do not share that work evenly. Under braking, the car pitches forward and load moves off the rear tires and onto the front tires. A front tire carrying more load can put more braking force to the road, so the system is designed to send the larger share of braking effort to the front axle. That is why the front calipers are larger, the front rotors are thicker and vented, and the front pads run through their friction material faster.

The rear brakes do less of the stopping, but they matter for stability. If the rear pads are worn to the backing plate or the rear rotors are scored, the car can feel less settled in a hard stop, and the ABS and stability systems have less to work with.

Standard Brakes vs the Sport Brake Package

Before you order anything, find out which brakes your Q60 has. Q60 Sport and Red Sport 400 models were built with a larger sport brake package, and those parts do not interchange with the standard brakes found on other trims. The easiest check is to look through the wheel: the sport package uses opposed-piston calipers with a fixed body (4 pistons front, 2 pistons rear), while standard brakes use a floating caliper that slides on pins.

The thickness figures above come from published replacement rotor specifications for the sport package. The number that governs your car is the minimum thickness stamped on the rotor itself or listed in the factory service manual, so measure against that. If your car has the standard floating-caliper brakes, the rotor sizes are different; match parts to your trim and compare the old pad shape to the new one before installing.

Notice the rear rotor on the sport package: it is a solid disc with a small drum machined inside the hat. The parking brake uses its own set of shoes inside that drum, separate from the rear pads. Those shoes see very little wear in normal use, but they should be inspected whenever the rear rotors come off.

What Wears First, and How to Tell

Expect the front pads to be the first service item. The rear pads typically outlast them, often by a wide margin, but driving style changes the gap. Hard stops, spirited driving and frequent hills load the front even more; mostly highway miles are easy on both ends.

Front brake wear signs

• A high-pitched squeal while braking that goes away when you release the pedal. That is usually the pad wear indicator, a metal tab that touches the rotor when the friction material gets thin.
• A grinding or scraping sound, which means the pad material is gone and metal is contacting the rotor. Stop driving on it and replace pads and rotors.
• Steering wheel shake under braking, usually from uneven rotor thickness or pad material deposits on the rotor face.
• A deep groove or a raised lip at the outer edge of the rotor face.

Rear brake wear signs

• A squeal or rubbing sound from the back of the car, sometimes more noticeable at low speed or when backing up.
• A pulsing felt through the seat or pedal rather than the steering wheel.
• A pad that is worn on one edge (tapered), which points to a sticking piston or a caliper that needs cleaning.
• A parking brake that needs more travel than it used to, which can mean the drum-in-hat shoes need adjustment.

Infiniti's maintenance schedule for the Q60 calls for inspecting brake pads and rotors every 10,000 miles or 12 months under standard driving, and every 5,000 miles or 6 months under severe driving. A quick look at pad thickness through the wheel spokes at every tire rotation is an easy habit that catches wear before it becomes rotor damage.

What to Replace Together

Brakes are serviced by axle, not by corner. Always replace pads on both sides of the same axle at the same time, and replace or resurface rotors in pairs. Mixing a new pad on one side with a worn pad on the other causes the car to pull under braking.

• Front pads and rotors together. On the Q60, the front rotors take the most heat. If they are below minimum thickness, grooved, or cause steering shake, replace them with the pads. New pads on a worn rotor bed in poorly and can come back noisy. Browse replacement brake rotors and brake pads by fitment.
• Hardware. New pad clips, anti-rattle springs and pins keep the pads moving freely and quiet. A brake hardware kit is inexpensive insurance against a return trip.
• Rear pads when they are close. If the fronts are due and the rears are near their limit, doing both axles in one visit saves labor and gives the car even pedal feel.
• Brake fluid. Infiniti lists brake fluid replacement every 20,000 miles or 24 months under standard driving, and every 10,000 miles or 12 months under severe driving. Fluid absorbs moisture over time, which reduces braking efficiency and promotes corrosion. Use the fluid specified on the reservoir cap or in your owner's manual.
• Calipers only if they fail. A caliper with a stuck piston, a torn boot or a leak should be replaced. Otherwise, the calipers usually just need cleaning and fresh hardware. When replacement is needed, see our brake calipers.

For front pads on this car, we carry Bendix front ceramic brake pads for the 2016-2022 Infiniti Q60. Ceramic compounds suit a daily-driven Q60: low dust on those large wheels and quiet operation. Confirm your caliper type before ordering, since sport and standard brakes take different pads.

How Hard Is the Job?

A front pad and rotor job on the Q60 is a reasonable driveway task for someone who has done brakes before. On the opposed-piston sport calipers, the pads usually come out after removing the retaining pins and anti-rattle spring, and the pistons are pushed back evenly on both sides. Replacing the rotors means removing the caliper assembly from the knuckle. Torque every fastener to the value in the factory service manual; guessing at caliper bolt torque is not worth the risk.

The rear is a little more involved on the sport package because of the drum-in-hat parking brake. Release the parking brake fully before pulling the rotor, and if the rotor will not come off, back off the parking brake shoe adjuster rather than hammering on it. After reassembly, adjust the parking brake shoes per the service manual so the parking brake holds and the shoes do not drag.

Finish by pumping the pedal until it is firm before moving the car, checking the fluid level, and bedding in the new pads with a series of moderate stops from moderate speed without coming to a full stop while the brakes are hot.

Frequently Asked Questions

Why do my Q60 front brakes wear faster than the rears?

Braking shifts the car's weight forward, so the front tires can use more braking force. The system is built to send most of the braking effort to the front, which wears the front pads and rotors faster.

Do I have to replace rotors every time I replace pads?

Not always. If the rotors are above minimum thickness, smooth and do not cause vibration, they can stay. If they are grooved, lipped, below minimum or causing shake, replace them with the pads.

Will sport brake pads fit a Q60 with standard brakes?

No. The sport package on Sport and Red Sport 400 models uses opposed-piston calipers and larger rotors, and its pads have a different shape. Check your calipers before ordering.

How often should I have my Q60 brakes inspected?

Infiniti's schedule calls for a pad and rotor inspection every 10,000 miles or 12 months, or every 5,000 miles or 6 months under severe driving conditions.

Can I replace only the front brakes and leave the rears?

Yes, if the rear pads and rotors measure within spec. Brakes are serviced per axle, so the front pair can be done alone. Just measure the rears while the car is in the air.
