Brake discs for Nissan Qashqai J11: how to choose and replace correctly

Brake system Nissan Qashqai J11 (2014–2021) is one of the key safety elements, and braking efficiency directly depends on the condition of the brake discs. Owners of this crossover are often faced with the question: when to change discs, which ones to choose (original or analogues), and how to avoid mistakes when replacing. In this article we will analyze everything in detail - from signs of wear to the nuances of installing new disks on the front and rear axles.

Feature Qashqai J11 — sensitivity to the quality of brake components. Cheap non-original discs can lead to vibrations on the steering wheel, accelerated wear of the pads, or even deformation of the hub. We analyzed owner reviews, technical data and manufacturer recommendations to create a checklist for the correct selection and replacement.

Signs of wear on brake discs on a Nissan Qashqai J11

The first signal about disk problems is steering wheel vibration or beating when braking. This indicates deformation or uneven wear on the working surface. On Qashqai J11 With a mileage of over 60–80 thousand km, this symptom is common, especially if the car was operated in an aggressive style or with low-quality pads.

Other warning symptoms:

• 🔊 Creaking or grinding when braking (even if the pads are new), deep grooves on the disc are possible.
• 📏 Reducing disc thickness below the permissible value (the minimum thickness is indicated on the disk itself or in the manual).
• 🚗 Pulling the car to the side when pressing the brake pedal - may indicate uneven wear or warping.
• 🔥 Brake overheating (a burning smell or smoke appears) - often associated with a jammed caliper or too thin discs.

On Nissan Qashqai J11 with engines 1.2 DIG-T, 1.6 dCi And 2.0 MR20DD The front discs wear out faster than the rear ones due to the greater load. The critical thickness of the front discs is 22 mm (with standard 25–26 mm), rear – 8–9 mm (with standard 10–11 mm). Exceeding these values leads to the risk of disc destruction during intense braking.

⚠️ Attention: If sharp "shoulders" (protrusions around the circumference) appear on the edge of the disc, this is a sign of extreme wear. Such discs are subject to immediate replacement, as they damage the brake pads and reduce braking efficiency.

Original brake discs vs analogues: what to choose?

Factory wheels for Qashqai J11 supplied by the company Akebono (Japan) or TRW (depending on the batch). Their articles:

• 🔧 Front disc: 40520-JM00A (left) / 40521-JM00A (right).
• 🔧 Rear disk: 40530-JM00A (for versions with rear axle drum brakes, discs are not provided).

The cost of original discs is high (from 8–12 thousand rubles per pair), so many owners choose analogues. Among the trusted brands:

• 🏆 Brembo (Italy) - optimal price/quality ratio, suitable articles 09.9362.11 (before) and 09.9363.11 (back).
• 🔹 ATE (Germany) - durable, but require running-in. Articles: 24.0120-0168.1 (before), 24.0132-0094.1 (back).
• 💰 TRW (UK) - a budget option, but the quality is lower than the original. The article numbers match the factory ones.
• ⚠️ Fenox/AvtoVAZ - not recommended due to the risk of warping and rapid wear.

Brand	Article (front)	Price per pair, rub.	Features
Original (Nissan)	40520-JM00A	10 000–14 000	Maximum resource, minimum vibration
Brembo	09.9362.11	7 500–9 000	10–15% lighter than the original, good cooling
ATE	24.0120-0168.1	6 000–7 500	Requires 500 km running-in, squeaking is possible
TRW	GDB1406	5 000–6 500	Budget option, average resource

When choosing analogues, pay attention to ventilated design (for front discs) and diameter matching (280 mm front, 260 mm rear for most versions). Discs without ventilation overheat during heavy braking, which is critical for Qashqai J11 with turbo engines (1.2 DIG-T, 1.6 dCi).

When to change brake discs: regulations and real experience

According to the regulations Nissan, brake discs on Qashqai J11 They do not have a fixed replacement period - their condition is checked at every maintenance (every 15 thousand km). However, in practice:

• 🚗 Front discs serve 60–100 thousand km (depending on driving style).
• 🔄 Rear discs (if installed) - up to 120–150 thousand km.
• ⚡ When driving aggressively (frequent sharp braking) the service life is reduced by 30–40%.

Important nuance: on Qashqai J11 with 1.5 dCi (diesel) and 2.0 MR20DD (petrol) rear axle is often equipped with drum brakes, which do not require disk replacement. You can check the type of brakes by VIN code or visually (disc brakes have a visible caliper and disc, drum brakes have a closed mechanism).

⚠️ Attention: If you notice that after replacing the pads the braking distance has increased and the pedal has become “soft”, this may indicate disc deformation. On Qashqai J11 This problem often occurs after overheating (for example, during a long descent from a mountain with constant braking).

To extend the life of disks:

Don't brake suddenly unless necessary

Avoid holding the pedal for long periods of time on descents (use engine braking)

Wash your wheels from salt and dirt in winter

Check the free play of the calipers every 30 thousand km-->

Step-by-step instructions for replacing brake discs on a Nissan Qashqai J11

Replacing disks with Qashqai J11 does not require special equipment, but will require care. To work you need:

• 🔧 Set of sockets and keys (for 14, 17, 19).
• 🔨 Jack and stops (be sure to fix the rear axle!).
• 🧲Brake fluid DOT-4 (for bleeding, if the system was opened).
• 🛠️ Lubricant for caliper guides (Molykote G-4500 or analogues).
• 🧴Brake cleaner (Brembo Cleaner).

Procedure (using the example of front discs):

1. Raise the car on a jack and remove the wheel. Be sure to secure the machine with supports!

2. Unscrew the two caliper mounting bolts (14mm wrench) and hang the caliper on a wire so as not to damage the hose.

3. Remove the brake pads (if necessary, replace them at the same time).

4. Unscrew the screw that secures the disc to the hub (an impact screwdriver or WD-40 may be required).

5. Remove the old disk. If it gets stuck, gently tap it through the wooden spacer with a hammer.

6. Clean the hub from rust and dirt, install a new disk, secure with a screw.

7. Reassemble the caliper in reverse order, lubricating the guides. Don't forget bleed the brakes, if you opened the hydraulic system!

For rear discs (if equipped), the process is similar, but you may need to remove the handbrake (release the cable through the adjuster under the car).

Common replacement mistakes and how to avoid them

Even experienced car owners make mistakes that lead to quick disc failure. Here are the most common:

• 🔩 Incorrect tightening of caliper bolts - leads to misalignment and uneven wear. Tightening torque: 30–35 Nm for front, 25–30 Nm for rear.
• 🧴 Lack of lubrication on the guides — the caliper may jam, which leads to local overheating of the disc.
• 🔧 Using old pads with new discs — the pads are already “ground in” to the old surface, which will accelerate wear.
• 🚿 Grease or dirt on the working surface of the disc - reduces braking efficiency.

Another typical problem is incompatibility of discs and pads. For example, if you install the pads Ferodo to disks ATE, squeaking may occur due to the different composition of the friction material. Always check compatibility using manufacturer's catalogs.

⚠️ Attention: After replacing disks first 200–300 km Avoid sudden braking - the new discs and pads should get used to them. During this period, the braking distance may increase by 10–15%.

What happens if you don't replace worn out discs on time?

Damage to brake pads and calipers, which leads to expensive repairs. Risk of disc rupture during heavy braking (especially at high speeds). Increase in braking distance by up to 30–40% due to a decrease in the contact area of ​​the pad with the disc.

Running in new brake discs: why is it important?

Breaking in (or "breaking in") new discs and pads is a critical step that many people skip. On Nissan Qashqai J11 With its sensitive braking system, improper break-in can result in:

• 🔊 Constant squeaking when braking.
• 📉 Reduced braking efficiency.
• 🔥 Local overheating and disk deformation.

How to roll in correctly:

1. For the first 100 km, avoid sharp braking (brake smoothly, with an effort of no more than 50% of the maximum).

2. From 100 to 300 km, gradually increase the load, but do not allow the wheels to lock.

3. After 300 km, perform several test brakes from 80–100 km/h to a complete stop to check the evenness of the pads.

During the running-in process, a uniform layer of friction material is formed on the disc and pads, which ensures optimal braking. If you skip this step, the surface will remain uneven, which will lead to vibrations and accelerated wear.

FAQ: Frequently asked questions about brake discs on Nissan Qashqai J11

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

Grooving is possible if the thickness of the disc after processing remains above the minimum permissible (22 mm at the front, 8 mm at the rear). However, on Qashqai J11 This is a temporary solution - machined discs last 2-3 times less than new ones due to reduced heat capacity. We recommend grinding only in case of slight deformation (runout up to 0.1 mm).

Which brand of pads is best for Brembo discs?

For disks Brembo pads of the same brand are optimally suited (P68055 for the front axle) or Ferodo Premier (FDB1887). These pads have a soft friction material that does not damage the discs and provides quiet braking. Avoid cheap pads (eg. Bosch QuietCast) - they can cause vibrations.

Why did vibration appear in the steering wheel after replacing the discs?

There are several reasons:

1. Incorrect tightening of the hub nut (torque should be 100–120 Nm).
2. Dirt getting between the hub and the disc (always clean the surface before installation!).
3. Defect of a new disk (rare, but occurs with non-original spare parts).
4. Unbalanced wheels (check after replacing rims).

If vibration remains, check the disc runout with an indicator - it should not exceed 0.03 mm.

Do I need to change the brake fluid after replacing the discs?

If you did not open the hydraulic system (did not disconnect the brake hoses), there is no need to change the fluid. However, on Qashqai J11 It is recommended to update the brake fluid every 2 years or 40 thousand km - it is hygroscopic and loses its properties. Signs of “old” fluid: dark color, burning smell, decreased braking efficiency.

Is it possible to install perforated wheels on the Qashqai J11?

Technically yes, but it's not practical for most owners. Perforated discs (Brembo Sport, EBC Ultimax) are better cooled, but:

• They wear out faster (resource is 30–40% lower).
• Requires more frequent pad replacements.
• Effective only for extreme driving (track, mountain serpentines).

For urban use, standard ventilated discs are sufficient.
