Brake discs <em>Nissan Murano Z51</em>: how to choose and replace correctly

Crossover Nissan Murano Z51 (2015-2021) is a car that combines comfort and dynamics, but even such characteristics depend on the condition of the braking system. The brake discs here experience serious loads: the weight of the car exceeds 1.8 tons, and the powerful 3.5 liter V6 (260 hp) requires reliable deceleration. In this article we will look at which discs are suitable for Murano Z51, how to determine their wear, which brands are trustworthy and whether you can handle the replacement yourself.

Feature of the model - ventilated discs on all wheels (even on the rear axle), which improves heat dissipation, but complicates the design. Standard sizes: 320×28 mm front and 324×12 mm behind. However, after 2018, some trim levels were equipped with wheels with changed parameters - more about this in the compatibility section. If you notice vibration in the steering wheel when braking or hear a squeaking sound, it's most likely time for a diagnosis. Now let's move on to the details.

Original brake discs for Murano Z51: part numbers and analogues

Factory wheels from Nissan are marked with articles 40520-5M000 (front left), 40520-5M001 (front right), 40530-5M000 (rear left) and 40530-5M001 (rear right). Their average cost at official dealerships is from 12,000 to 18,000 rubles per piece. However, many owners prefer analogues from trusted brands, which are often not inferior in quality, but are 30–50% cheaper.

Popular alternatives include:

• 🔹 Brembo is an Italian brand known for sports braking systems. For Murano Z51 suitable for series wheels Max (articles 09.9692.11 And 09.9693.11).
• 🔹 ATE - German quality at an affordable price. Articles: 24.0120-0190.2 (before) and 24.0120-0191.2 (back).
• 🔹 TRW - a budget option with good reviews. Suitable models: DF4885 And DF4886.
• 🔹 DBA - Australian wheels with slots for better cooling (series Street Series).

When choosing analogues, pay attention to disk thickness: The new one should be no thinner than 28 mm (front) and 12 mm (rear). Minimum permissible thickness after wear - 26 mm And 10 mm accordingly. Exceeding these values threatens overheating of the brake fluid and system failure in an emergency.

⚠️ Attention: On restyled versions Murano Z51 (after 2018) sometimes discs with an increased diameter were installed 330 mm front. Check the dimensions before purchasing by checking the nameplate on the old disk or in the electronic catalog Nissan.

Signs of wear: when is it time to change discs

Brake discs Nissan Murano Z51 designed for 80,000–120,000 km mileage, but the actual period depends on driving style and operating conditions. Here are the key symptoms indicating the need for replacement:

• 🚨 Vibration on the steering wheel or brake pedal when slowing down - a sign disc deformation (often due to overheating).
• 🚨 Creaking or grinding - may indicate critical wear or foreign particles getting between the pad and the disc.
• 🚨 Increased braking distance — even with serviceable pads, worn discs adhere worse.
• 🚨 Visible grooves or cracks on the working surface of the disk.
• 🚨 Uneven wear (one disc is thinner than the other) - often associated with a stuck caliper.

For an accurate diagnosis, use caliper or special wear indicator. Measure the thickness of the disc at 3-4 points around the circumference. If the difference exceeds 0.05 mm, the disk needs to be replaced. Also note collar along the edge of the disk - if its height exceeds 1 mm, this is a signal to action.

Don’t ignore even small cracks: when heated, they can expand and lead to disk destruction at high speed. This is especially true for Murano Z51 with its heavy weight and powerful engine.

Portable vs. perforated wheels: which is better for Murano Z51

When replacing disks, many owners think about modifications with slots or perforation. Let's figure out whether this is justified for a crossover.

Disk type	Benefits	Disadvantages	Recommendation for Murano Z51
Standard (smooth)	Longer service life, cheaper, less noise	They dissipate heat worse and are prone to deformation during heavy braking.	✅ Optimal for a quiet ride around the city
With slots	Cool better, self-clean from dust	Wear out faster and may cause vibrations	⚠️ Suitable for active driving, but requires frequent replacement
Perforated	Maximum heat dissipation, minimal risk of deformation	Expensive, noisy, wears out pads faster	❌ Redundant for everyday use

For most owners Murano Z51 best choice - standard ventilated discs from trusted brands. Perforated options are justified only when aggressive driving style or participation in competitions. Slots can be useful if you often drive on mountain serpentines or tow a trailer, but remember: they reduce the life of the disc by 20-30%.

Step-by-step instructions for replacing brake discs

Replacing disks with Nissan Murano Z51 - a task of medium complexity. If you have the tools and minimal experience, you can do it in 2–3 hours. You will need:

• 🔧 Jack and stops (or lift)
• 🔧 Set of sockets and keys (including Torx T50 for caliper guides)
• 🔧 Brake pad puller
• 🔧 Torque wrench (for tightening with torque 100–120 Nm)
• 🔧 Copper grease for guides

Sequence of actions:

1. Jack up the car and remove the wheel. Be sure to secure the machine with supports — Murano heavy, and the jack may fall off!
2. Unscrew the two caliper mounting bolts (usually 17 mm) and hang it on a wire so as not to damage the hose.
3. Remove the brake pads and disconnect the wear sensor (if equipped).
4. Unscrew the screw securing the disc to the hub (Torx T50) and remove the disc. If it is stuck, use a puller or gently tap it through a wooden spacer with a hammer.
5. Install the new disk, maintaining alignment. Tighten the fixing screw to a torque 8–10 Nm.
6. Reassemble the caliper in reverse order, lubricating the guides. It is recommended to replace the pads at the same time as the discs.

⚠️ Attention: After replacing disks be sure to bleed the brake system, if the hydraulic line was opened. Also, avoid sudden braking for the first 200 km - the pads need to get used to the new surface.

If you are not confident in your abilities, contact the service. Average cost of replacing drives Murano Z51 in Moscow - from 3,000 to 5,000 rubles per axle (excluding spare parts).

Common replacement mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to premature disc wear or malfunctions. Here are the most common:

1. Ignoring hub runout. If the hub is warped, the new disc will quickly warp. Check it before installation dial indicator (permissible runout - no more 0.03 mm).
2. Lack of cleaning of seating surfaces. Rust or dirt between the disc and hub causes imbalance. Always clean surfaces wire brush.
3. Bolt tightening. Excessive tightening torque will deform the disc. Use a torque wrench!
4. Saving on pads. New discs + old pads = uneven wear and squeaking. Always change them in pairs.

Another typical problem is corrosion of caliper guides. If they are not lubricated, the caliper may jam, which leads to uneven disc wear. When replacing, be sure to:

• 🔧 Clean the guides from old grease.
• 🔧 Apply a new layer high temperature copper grease (For example, Permatex 24110).
• 🔧 Check the guide boots - if they are torn, replace them.

FAQ: Answers to popular questions

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

Grooving is possible if the thickness of the disk after processing remains within the tolerance (at least 26 mm front and 10 mm rear). However, on Murano Z51 This is a temporary solution: due to the heavy weight of the machine, the discs quickly wear out again. The groove is justified only when slight runout (up to 0.1 mm).

Which pads are best to install with new discs?

For Murano Z51 Recommended pads:

• AKEBONO ACT907A — original, soft for discs.
• Ferodo FDB1989 - good balance of price and quality.
• Brembo P85060 - for an aggressive driving style.

Avoid cheap pads with a high metal content - they accelerate disc wear.

How long do brake discs last on a Murano Z51?

The service life depends on the conditions:

• 🏙 City riding: 80,000–100,000 km.
• 🛣 Route: up to 120,000 km (less loads).
• 🏔 Mountain roads: 50,000–70,000 km (due to frequent braking).

Check the thickness of the discs regularly - this will prolong their life.

Do I need to bleed the brakes after replacing the discs?

Pumping is only required if you opened the hydraulic line (for example, the brake hose was disconnected). If you simply removed the caliper without breaking the seal, bleeding is not necessary. However, after replacing the discs, always check the brake fluid level in the reservoir - with worn pads, the caliper pistons are extended to their maximum, and after installing new pads, the level may drop.

Is it possible to drive with a cracked wheel?

Absolutely not. Cracks in the disk are a risk destruction on the go, especially when heated. Even small cracks expand over time. If you find a defect, replace the disk immediately, even if the thickness is still normal.
