Brake discs <em>Nissan Murano Z50</em>: how to choose and replace correctly

Brake system Nissan Murano Z50 (2007–2014) is a critical component, the condition of which determines road safety. The brake discs of this crossover are subject to intense wear, especially during aggressive driving or use in city traffic jams. Unlike newer models, Murano Z50 has specific requirements for materials and disk sizes, which complicates the selection of spare parts.

In this article we will look at everything the owner needs to know: from signs of wear And compatibility of original and analog discs to step-by-step replacement instructions. We will pay special attention A unique feature of the Murano Z50 is the increased diameter of the rear discs (320 mm) on versions with AWD, which is often overlooked when selecting spare parts. We will also debunk the myths about “eternal” perforated disks and explain why ventilated discs They don't always justify their price.

Technical characteristics of brake discs Nissan Murano Z50

Before purchasing new disks, you need to know exactly their parameters. An error in size or material can lead to vibrations, accelerated pad wear and even brake system failure in a critical situation. Below are the official data for all modifications of the Murano Z50:

Parameter	Front discs	Rear wheels (2WD)	Rear wheels (AWD)
Diameter, mm	320	302	320
New disc thickness, mm	28	12 (solid)	22 (ventilated)
Minimum thickness, mm	26	10	20
Type	Ventilated	Solid	Ventilated
Fastening	5 holes, PCD 114.3	5 holes, PCD 114.3	5 holes, PCD 114.3

⚠️ Attention: On all-wheel drive (AWD) versions, the rear discs are identical in diameter to the front ones, but have a different hub design. Installing disks from the 2WD version will lead to incompatibility with caliper and will require mounting modifications.

It is also worth considering that Murano Z50 with engine VQ35DE (3.5 l) is equipped with more massive wheels than versions with VQ25DE (2.5 l). This is due to the increased vehicle weight and higher braking loads.

Signs of wear: when is it time to change discs

The manufacturer recommends checking the condition of the brake discs every 20–30 thousand km, but actual service life depends on driving style and operating conditions. Here are the key symptoms indicating the need for replacement:

• 🔴 Steering wheel vibration when braking - a sign uneven wear or disc deformation (so-called “beating”).
• 🔊 Creaking or grinding - may indicate contact of the pad with a worn edge of the disc or ingress of foreign particles.
• 📏 Reducing disc thickness below the minimum value (see table above). You can check this with a caliper.
• 🔥 Brake overheating — if after intense braking the discs remain hot for longer than 10–15 minutes, this is a signal of a decrease in their heat-dissipating properties.
• 🚗 Pulling the car to the side when braking, uneven wear or warping of the discs is possible.

⚠️ Attention: If there are deep furrows (more than 1 mm), it must be replaced even if the minimum thickness is maintained. Such defects accelerate pad wear and reduce braking efficiency by 30–40%.

For diagnosis, you can use a simple test: when driving at a speed of 60–80 km/h, slow down slightly. If it is felt pedal pulsation or steering wheel, the discs require sharpening or replacement. In service centers they use runout indicator, which shows deviations from the plane of more than 0.05 mm.

Original vs analogues: what to choose for Murano Z50

Owners Nissan Murano Z50 Often faced with a dilemma: buy original discs or high-quality analogues. Let's look at the pros and cons of each option.

Original wheels Nissan

Article numbers of original wheels for Murano Z50:

• 📌 Front disc: 40520-4M000 (ventilated, 320 mm)
• 📌 Rear drive (2WD): 40530-4M000 (solid, 302 mm)
• 📌 Rear Disc (AWD): 40530-4M010 (ventilated, 320 mm)

✅ Pros:

• 🔹 Ideal compatibility with calipers and pads.
• 🔹 Guaranteed quality of metal and processing.
• 🔹 Compliance with factory heat transfer standards.

❌ Cons:

• 💰 High price (from 12,000 rubles per disc).
• 🛒 Long delivery times (often made to order).

Analogs from leading manufacturers

High-quality analogues can be no worse than the original, but require careful selection. The best brands for Murano Z50:

Brand	Article (front)	Article (rear AWD)	Price, rub.
Brembo	09.9662.11	09.9663.11	8 500
ATE	24.0120-0179.2	24.0120-0180.2	7 800
TRW	DF4830	DF4831	6 200
Febi	22621	22622	5 500

💡 Expert advice: When choosing analogues, pay attention to alloy composition. Discs from high carbon steel (For example, Brembo) last longer, but require longer break-in. Discs from cast iron (For example, TRW) are cheaper, but wear out faster under intense loads.

The myth about perforated discs

Drilled or slotted wheels are often marketed as "sports" wheels, but... Murano Z50 they are not always justified. Their advantages:

- Better removal of gases and dust.

- More stable braking at high temperatures.

However, the disadvantages outweigh:

- They wear out faster (20–30% less service life).

- Reduce pad life due to increased abrasive action.

- Prone to cracks during sudden temperature changes (relevant for the Russian climate).

The exception is if you drive the Murano in mountainous areas or engage in motorsports.

Step-by-step instructions for replacing brake discs

Replacing disks with Nissan Murano Z50 - a task of medium complexity that can be completed independently if you have the tools. You will need:

• 🔧 Set of sockets and keys (14 mm, 17 mm, 19 mm).
• 🔨 Socket wrench for caliper guides.
• 🛠 Jack and stops.
• 🧲 Brake disc remover (sticky discs).
• 🧴 Copper grease for guides.

⚠️ Attention: Before starting work pump out some of the brake fluid from the tank! When the caliper piston is pressed in, the fluid may overflow, which will lead to air entering the system.

Procedure:

1. Removing the caliper:

   Unscrew the two caliper mounting bolts (usually 14 mm), then carefully hang the caliper on the wire without disconnecting the brake hose. Don't press the brake pedal in this position!

2. Removing the disk:

   If the disc is stuck to the hub, use a puller or gently tap it through a wooden spacer with a hammer. Do not hit the disc itself, as this may deform it.

3. Cleaning the hub:

   Thoroughly clean the seat from rust and dirt. Apply a thin layer copper grease onto the surface of the hub to prevent corrosion.

4. Installing a new disk:

   Install the rim and secure it with the wheel bolts (do not fully tighten). Then return the caliper to its place and replace the brake pads (it is recommended to always change them along with the discs).

5. Bleeding the brakes:

   After assembly, press the brake pedal several times until the caliper pistons are in their working position. Bleed the system if you notice softness in the pedal.

🔧 Important: After replacing disks first 200–300 km Avoid sudden braking - the pads need time to break in to the new surface. During this period, braking efficiency may be reduced by 10–15%.

Common replacement mistakes and how to avoid them

Even experienced car owners make mistakes that shorten the life of discs or worsen braking properties. Here are the most common:

• 🔧 Ignoring hub runout. If the hub is deformed, a new disc will quickly repeat its shape. Check runout indicator (tolerance - no more than 0.03 mm).
• 🧴 Using unsuitable lubricant. Never apply to caliper guides. graphite lubricant or Litol — they destroy rubber boots. Only copper or specialized brake lubricant.
• 🔨 Retightening caliper bolts. The tightening torque of the caliper mounting bolts is 30–35 Nm. Exceeding will lead to deformation of the bracket.
• 🚗 Failure to follow the replacement procedure. Always change disks in pairs on the same axis (both front or both rear), otherwise there will be a difference in braking force.
• 🔥 Neglecting break-in. In the first days after replacement, avoid aggressive braking And long descents with brakes - this leads to overheating and deformation of new disks.

⚠️ Attention: If, after replacing the disks, extraneous noise (for example, a whistle when braking), this is not always a defect. New pads and discs can “break in” within 1–2 weeks. However, if the noise persists or gets worse, check:

• Installation quality anti-whistle plates (if they are provided for by the design).
• No gaps between the pad and the caliper.
• Condition guides (they should move freely, without jamming).

📌 Recommendation: If you choose disks for Murano Z50 with a mileage of more than 150 thousand km, pay attention to the condition of the wheel bearings. Worn bearings can cause new discs to wear unevenly.

Caring for and extending the service life of brake discs

Average life of brake discs Nissan Murano Z50 amounts to 50–70 thousand km, but with proper care this figure can be increased by 20–30%. Here are the key recommendations:

• 🚿 Disc washing. Regularly clean the discs from dirt and salt (especially in winter). Use special cleaners (For example, Liqui Moly Bremsen-Reiniger), but avoid harsh acid-based products.
• 🚗 Driving style. Try to avoid sudden braking from high speeds. Use engine braking on the slopes.
• 🔧 Control of pads. Worn pads (friction layer thickness less than 3 mm) accelerate disc wear by 2–3 times.
• 🌡 Overheating After intensive braking, let the discs cool down (do not put the car on the handbrake immediately after stopping - this can lead to deformation of the disc).
• 🛠 Diagnostics. Every 10 thousand km, check the thickness of the discs and the presence of cracks. For Murano Z50, the critical thickness of the front discs is - 26 mm, rear (AWD) — 20 mm.

⚠️ Attention: If you frequently drive off-road or in high humidity conditions, treat non-working surfaces of disks (for example, internal ribs) anti-corrosion composition. This will prevent the disc from sticking to the hub and will make future replacement easier.

💡 Advice: When replacing brake fluid (recommended every 2 years), check the condition brake hoses. Cracks or swelling in the hoses can lead to uneven pressure in the calipers and, as a result, accelerated wear of the discs.

FAQ: Frequently asked questions about brake discs Nissan Murano Z50

Is it possible to sharpen the discs instead of replacing them?

Grooving is possible if the disc thickness exceeds the minimum allowable (see table above). However, keep in mind:

• Grooving reduces the disk life by 30–40%.
• On Murano Z50 With AWD, it is more difficult to grind the rear discs due to their large mass.
• The cost of turning (from 1,500 rubles per disc) is often comparable to the price of new budget discs.

🔹 Conclusion: Grooving is justified only for new discs with slight runout (up to 0.1 mm).

Which discs are better - perforated or ventilated?

For Murano Z50 ventilated discs (standard) are preferable in 90% of cases. Perforated discs:

• 🔹 Cool faster, but also wear out faster.
• 🔹 Effective only under extreme loads (for example, towing a trailer).
• 🔹 Requires more frequent replacement of pads.

🔹 Recommendation: Unless you drive your Murano in extreme conditions, opt for standard ventilated wheels.

Do I need to change the pads along with the discs?

✅ Yes, definitely. New discs and old pads will not rub in evenly, which will lead to:

• 🔹 Accelerated disc wear (up to 20% faster).
• 🔹 Vibrations when braking.
• 🔹 Reduced brake efficiency.

The exception is if the pads are almost new (have driven less than 5 thousand km).

What to do if the brakes squeak after replacing the discs?

Creaking in the first 1–2 weeks is normal (the pads are rubbing in). If the noise continues:

• 🔹 Check it out anti-whistle plates (they must be installed between the pad and the caliper).
• 🔹 Apply special lubricant on the back of the pads (for example, ATE Plastilube).
• 🔹 Make sure that the pads and discs are from the same manufacturer (incompatible materials may squeak).

⚠️ If the creaking is accompanied vibration, the disks may be defective or incorrectly installed.

How often should you check the brake rotors on your Murano Z50?

Recommended schedule:

• 🔹 Every 10 thousand km — visual inspection for cracks and corrosion.
• 🔹 Every 20 thousand km - measure the thickness of the disks with a caliper.
• 🔹 Every 30 thousand km — check the runout (in the service).
• 🔹 At every maintenance — assessment of the condition of calipers and guides.

🔹 Important: After riding in deep puddles or in salty environments (in winter), rinse the discs with water to remove aggressive chemicals.
