2015-2022 Nissan Murano Brake Noise: Squeal, Grinding and Pulsation Causes

By Core Brake Parts Tech Team — Circleville, OH warehouse

Brake noise on a 2015-2022 Nissan Murano usually comes down to three things: a high-pitched squeal from pad vibration, dry or worn hardware, or a wear indicator touching the rotor; a grinding sound that means friction material is gone or a caliper is dragging; and a pulsation you feel in the pedal or steering wheel from rotor runout or thickness variation. The sound tells you where to start looking, and most fixes are pads, rotors and fresh hardware, not a major repair.

This guide walks through how the third-generation Murano's brakes are built, how to tell the noises apart, what causes each one, and which parts actually fix it.

How the 2015-2022 Murano Brake System Is Built

The third-generation Murano runs ventilated disc brakes at all four corners. Nissan's 2019 press kit lists a front rotor of 12.6 x 1.1 inches and a rear rotor of 12.1 x 0.6 inches, with ABS, Electronic Brake force Distribution (EBD) and Brake Assist standard. The same press kit lists a foot-operated parking brake, not an electronic one, so there is no parking brake motor on the rear caliper to retract before a rear pad job.

Two details matter for noise. First, the front rotor is much thicker than the rear, because the front brakes do most of the work and wear fastest. Second, the Murano is a midsize crossover with a 3.5-liter V6, and heat from repeated stops is what glazes pads, fatigues anti-rattle clips and helps rotors develop uneven thickness over time.

Always confirm rotor size and pad shape against your own vehicle before ordering, since trim and model year can change the part.

Squeal: The Most Common Murano Brake Noise

Wagner's technical guidance is direct about it: vibration is the main source of noise in a brake system. A squeal is the pad and rotor vibrating at a frequency you can hear, and anything that lets the pad move or ring more freely makes it worse.

What causes squeal

• Wear indicators. Many pads carry a small metal tab designed to rub the rotor when the friction material gets thin. Bosch lists worn pads and their wear indicators as a leading cause of squeaking. If the squeal appears while driving and changes when you touch the brakes, check pad thickness first.
• Worn or missing shims and clips. Wagner notes that anti-rattle clips and springs lose their spring tempering from brake heat. A tired clip lets the pad rattle and sing in the caliper bracket.
• Dry or corroded guide pins. Corroded slide pins keep the caliper from releasing cleanly, which causes noise and uneven pad wear.
• Brake dust and rust. Dust trapped between pad and rotor, and rust on the hub face, both contribute to noise.
• New pads that were never bedded in. Pads that have not transferred an even layer of material onto the rotor are more likely to squeal early on.

How to diagnose it

Note when the noise happens. A squeal only in the first few stops on a damp morning is often surface rust being cleaned off the rotor and usually fades. A squeal on every light stop that goes away under firm braking points to pad vibration and hardware. A steady chirp while driving with no pedal applied points to a wear indicator or a dragging pad. Pull the wheels and measure remaining pad material at both ends of each pad; uneven wear between the inner and outer pad is a sign of a sticking caliper pin.

Grinding: Stop Driving on It

A coarse grinding sound usually means metal is touching metal. Once the friction material is gone, the steel pad backing plate cuts into the rotor, and a rotor that could have been reused becomes scrap quickly. On a Murano, the front pads are the most likely culprit because they carry most of the braking load.

Grinding is not always worn pads. Bosch points to a sticking caliper, which keeps the pads pressed against the rotor, as another cause of grinding and a jittery feel. On the Murano, check for:

• A wheel that is noticeably hotter than the others after a drive (dragging caliper)
• A pull to one side under braking
• Pad material worn down to the backing plate on only one side of one caliper
• Stones or debris caught between the rotor and the dust shield, which can grind even with good pads

If the rotor is scored deep enough to catch a fingernail, or is below the minimum thickness stamped on the rotor, replace it rather than resurfacing it. Pads and rotors are both available in our brake pads collection and brake rotors collection.

Pulsation and Vibration When Braking

A pulsing pedal or a steering wheel that shakes under braking is usually called "warped rotors," but the cause is almost always uneven rotor thickness or excessive lateral runout. Wagner lists excessive rotor runout, hub rust and loose wheel bearings as causes, and Bosch notes that a rotor with an uneven contact surface produces vibration and rattle.

Why Murano rotors develop it

• Rust or scale on the hub face. Even a thin layer of rust between the hub and rotor tilts the rotor slightly, so it wobbles as it spins. Over thousands of miles the pads wear the high spots and create thickness variation. Wagner calls for cleaning hub rust and corrosion during any brake job.
• Uneven lug nut tightening. Impact guns and uneven torque can distort the rotor hat. Tighten lug nuts in a star pattern with a torque wrench to the value in the owner's manual.
• Heat and pad deposits. Holding the brakes hard at a stop right after a hot, hard stop can imprint pad material onto one spot of the rotor.
• Worn wheel bearings. A loose bearing lets the rotor move, which shows up as pulsation and noise.

How to tell front from rear

Vibration felt mostly in the steering wheel usually points to the front rotors. Pulsation felt mainly in the pedal and seat, with a steady steering wheel, points toward the rear. A shop can confirm with a dial indicator on the rotor face and a micrometer at several points around it.

ABS Recalls to Rule Out First

Before chasing noise, check your VIN for open recalls. NHTSA lists several ABS actuator recalls that cover these model years:

• 15V364000 - certain 2015 Murano vehicles built December 4, 2014 to March 17, 2015, for possible contamination in the ABS actuator solenoid valves.
• 16V636000 and 18V601000 - certain 2015-2017 Murano vehicles, for ABS actuator pumps that may allow brake fluid to leak onto an internal circuit board.
• 19V807000 - an expansion covering certain 2015-2018 Murano vehicles that were previously recalled and unrepaired, where dealers replace the ABS actuator.

These recalls are not about pad or rotor noise, but an ABS warning light, a burning smell or a change in pedal feel should send you to a dealer for a recall check first. Recall repairs are done free of charge.

The Fix: What to Replace and How Hard It Is

Most Murano brake noise is fixed with a complete brake job on the affected axle, not just pads. Replacing pads alone on a rotor with thickness variation, or reusing fatigued clips, is the most common reason noise returns within a few months.

Replace together

• Pads on both sides of the axle, always as a set. For the rear, see our 2015-2022 Nissan Murano / Pathfinder rear ceramic brake pads by Bosch.
• Rotors if they are below minimum thickness, deeply scored, or measured with excessive runout
• New abutment clips and shims from a brake hardware kit
• Caliper slide pin boots and fresh high-temperature brake grease on the pins
• A replacement brake caliper if a piston is seized or a pin will not free up

Install tips that prevent noise

• Follow the shim instructions for your pads. Wagner advises a light coat of silicone lubricant on the back of constrained-layer shims only, and no compound at all on pads with bonded insulators.
• Clean the hub face to bare metal before fitting the rotor.
• Clean new rotors of dust and residue. Wagner recommends soap, water and a bristle brush.
• Bed the pads in. Wagner's burnish procedure is 20 slow-downs from 50 mph to 20 mph with light pedal pressure, allowing at least 30 seconds between each.

For a home mechanic with jack stands, a torque wrench and a caliper piston tool, one axle of pads and rotors on a Murano is a moderate job. Ceramic pads are a popular choice for this vehicle because they run quiet with light dust; browse ceramic brake pads for options.

Do Not Forget the Brake Fluid

Brake fluid absorbs moisture over time, which lowers its boiling point and promotes internal corrosion in calipers and the ABS unit. Nissan's maintenance schedule for the 2015 Murano calls for replacing brake fluid every 20,000 miles or 24 months in standard driving, and every 10,000 miles or 12 months under severe conditions. Use the fluid type printed on your master cylinder cap and in your owner's manual. A flush does not cure noise directly, but it helps keep pistons and pins from corroding and sticking, which is a root cause of grinding and uneven wear.

Frequently Asked Questions

Why do my new Murano brakes squeal?

New pads often squeal when they were not bedded in, the shims or clips were reused or left out, or the slide pins were not lubricated. Check the hardware first, then perform a proper burnish procedure.

Is it safe to drive a Murano with grinding brakes?

No. Grinding usually means the pad backing plate is contacting the rotor, which reduces stopping power and destroys the rotor quickly. Have it inspected right away.

Can I just resurface my Murano rotors to stop pulsation?

Only if the rotor will stay above the minimum thickness stamped on it after machining. If it will not, or if the rotors are heavily rusted, new rotors are the better fix.

Do the front and rear Murano brakes use the same pads?

No. The front and rear use different rotor sizes and different pad shapes, so they are sold separately. Always match pads to your year and axle.

Could my brake noise be related to the ABS recall?

The ABS actuator recalls address fluid leaks and valve contamination, not pad or rotor noise. Still, run your VIN through NHTSA or a Nissan dealer, since open recalls are repaired free.
