Replacing brake pads on a Nissan X-Trail T31: instructions with photos and tips

Brake system Nissan X-Trail T31 (2007-2013) requires regular maintenance, and replacing the pads is one of the most common procedures. Depending on the driving style and operating conditions, the front pads wear out over time. 30–50 thousand km, and the rear ones - for 60–80 thousand km. Ignoring their condition leads to damage to the brake discs, an increase in braking distance, and even system failure in a critical situation.

In this article you will find step by step instructions for replacing pads X-Trail T31 taking into account the features of the model: from selecting spare parts to running in new parts. We'll look at what tools you'll need, how to avoid common mistakes (for example, incorrect installation of guides or forgotten lubrication), and give recommendations for diagnosing related problems - for example, squeaking or vibration when braking.

If you've never done brake repair, don't be alarmed: the procedure is simpler than it seems. The main thing is to maintain consistency and not skimp on the quality of consumables. For clarity, the article has unique data on fastener tightening torques for T31 (they are often missed in general instructions), as well as tips on working with the electronic handbrake, which makes replacing the rear pads more difficult.

When is it time to change brake pads on a Nissan X-Trail T31

The manufacturer recommends checking the thickness of the pads every 15 thousand km, but the actual timing depends on several factors:

• 🚗 Riding style: aggressive braking in the city wears out the pads 2-3 times faster than quiet driving on the highway.
• 🏔️ Operating conditions: Frequent off-road or mountain driving increases the load on the brakes.
• 🔧 Parts quality: cheap pads (for example, no-name brands) can be washed out in 20 thousand km, while the original ones Nissan or Brembo last longer.
• 🚨 Wear symptoms: creaking, squealing, increased pedal travel or steering wheel vibration when braking.

The minimum permissible thickness of the friction layer is 2–3 mm. If the pad has worn down to the metal base, it must be replaced urgently, otherwise it will damage the brake disc. You can check wear visually through the wheel spokes or using wear indicator (a metal tongue that begins to creak in critical condition).

⚠️ Attention: On X-Trail T31 with electronic handbrake (EPB) the rear pads wear unevenly due to automatic tightening. If you hear a squeak on only one side, this is a reason to check the condition of both wheels.

Another indirect sign - dust on wheels. If it has become darker and more abundant, this indicates accelerated wear of the friction material. Also note brake fluid: if its level in the reservoir drops without visible leaks, this may indicate wear on the pads (the caliper pistons move out more, compensating for the decrease in thickness).

Which pads to choose for Nissan X-Trail T31: original vs analogues

There are dozens of pad options on the market for T31, but not all of them are equally effective. Original spare parts from Nissan (article 40520-4M000 for front and 40520-4M010 for the rear) guarantee compatibility and long service life, but their price is often too high. Alternatives from trusted brands can be just as good, and sometimes even better.

Brand	Article (front)	Article (rear)	Features	Average price, rub.
Nissan (original)	40520-4M000	40520-4M010	Optimal balance of wear resistance and braking properties. Suitable for any riding style.	3 500–4 200
Brembo	P 24 056	P 24 057	High coefficient of friction, minimal disc wear. Ideal for active driving.	4 000–4 800
ATE	13.0460-7207.2	13.0460-7208.2	Soft pads with low noise level. Good for the city, but wear out faster.	2 800–3 500
TRW	GDB1466	GDB1467	Budget option with good braking properties. May squeak at low temperatures.	2 200–2 800
Ferodo	FDB1466	FDB1467	Eco-friendly (low-metallic), but require running-in. Suitable for a quiet ride.	3 000–3 700

When choosing, pay attention to friction material composition:

• 🔥 Semi-metallic (semi-metallic): durable, but noisy and aggressive to discs. Optimal for off-road use.
• 🌿 Organic (organic): quiet and soft, but wears out faster. Good for the city.
• 🧲 Ceramic (ceramic): the most expensive, but they practically do not wear out the discs and do not generate dust. Ideal for premium versions X-Trail.

⚠️ Attention: On X-Trail T31 with engines 2.0 MR20DE And 2.5 QR25DE the front pads are wider than on diesel versions (2.0 M9R). Check the articles by VIN code to avoid mistakes!

Do not buy pads without packaging or with traces of counterfeit. Original parts always have:

• 📦 Hologram or protective stickers on the packaging.
• 🔢 Clearly printed article and brand logo.
• 📄 Warranty card or installation instructions.

Tools and materials for replacing brake pads

To work you will need specialized tool, some of which can be replaced with analogues, and some of which will have to be bought or borrowed. Here's the full list:

• 🔧 Jack and stops: be sure to use rolling jack or rhombic with support under the threshold. Do not work on the same jack under any circumstances!
• 🔩 Keys and heads: spanner for 14 mm (for caliper guides), socket heads on 17 mm And 19 mm (for wheel bolts and caliper brackets).
• 🔨 Hammer and chisel: may be needed to remove stuck pads or bolts.
• 🧴 Lubricants: copper paste for caliper guides and extreme pressure lubricant for the back of the pads.
• 🔧 Special tools: sliding pliers for the caliper piston, caliper puller (optional, but simplifies the work).
• 📏 Vernier caliper: for measuring the thickness of pads and discs.
• 🧤 Gloves and glasses: Brake dust is toxic; avoid contact with skin and eyes.

If you have X-Trail T31 with electronic handbrake (EPB), additionally you will need:

• 🔌 Diagnostic scanner: to enter the caliper into service mode (for example, Launch X431 or Autel MaxiCOM).
• 🔋 Cordless screwdriver: to unscrew the motor EPB (if the mechanism needs to be replaced).

Don’t skimp on lubrication: cheap analogues can boil when heated, which will lead to the caliper jamming. Recommended brands:

• 🧴 Slipkote 220-R DBC - for guides.
• 🧴 Permatex 24110 - universal anti-seize lubricant.
• 🧴 TRW PFG110 - for the back side of the pads.

If you plan to replace the brake discs as well, please note that for X-Trail T31 their minimum thickness is:

• 🚗 Front: 22 mm (new - 25 mm).
• 🚙 Rear: 8.4 mm (new - 10 mm).

Step-by-step instructions: replacing front brake pads

Front pads on X-Trail T31 They are easier to change than the rear ones, since there is no electronic handbrake. Follow the instructions to avoid errors:

1. Preparation:

   Place the car on a level surface, engage first gear (or P for an automatic) and place chocks under the rear wheels. Loosen the wheel bolts, but do not remove it completely.

2. Removing the wheel and caliper:

   Raise the car with a jack, remove the wheel and clean the caliper of dirt. Unscrew the two caliper mounting bolts (key on 14 mm) and carefully remove it, hanging it on a wire from the spring - Do not let it hang on the hose!

3. Replacing pads:

   Remove the old pads and clean the seats from rust. Install new pads, first applying a thin layer extreme pressure lubricant on their back side. Make sure the retaining springs (if equipped) are in place.

4. Recessing the piston:

   Using sliding pliers or a special tool, press the caliper piston back. Do this evenly so as not to distort the cuff. If the piston does not recess, check the cap of the brake fluid reservoir (it needs to be opened to relieve pressure).

5. Assembly:

   Install the caliper in place, tighten the bolts to a torque 30–35 Nm and put on the wheel. Repeat the procedure for the second wheel.

After replacement press the brake pedal several timesso that the pistons are in working position. Then check the brake fluid level and add if necessary.

⚠️ Attention: On X-Trail T31 with engine 2.5 QR25DE The front calipers are wider than on 2.0 MR20DE. If you are installing pads from a different version, they may not fit in place!

If the brake pedal becomes soft after replacement, bleed the system. To do this:

1. Place a transparent hose onto the caliper fitting and lower the other end into a container with brake fluid.
2. Have an assistant press the brake pedal 3-4 times and hold it down.
3. Unscrew the fitting ½ turn, release the air and screw it back on.
4. Repeat until no more bubbles appear in the hose.

Replacing rear brake pads: EPB features

Rear pads on X-Trail T31 with electronic handbrake (EPB) are more difficult to change due to the need to enter the system into service mode. If you ignore this step, the caliper will not allow the piston to sink, and the new pads will not fit.

Replacement algorithm:

1. Disabling EPB:

   Connect the diagnostic scanner and in the menu Brake system → EPB → Service mode activate the function Retraction (piston retraction). Alternatively, you can disconnect the negative battery terminal for 10 minutes, but this will reset all settings (eg radio and clock).

2. Removing the caliper:

   Unscrew the two caliper mounting bolts (key on 14 mm) and remove it by hanging it on a wire. Be careful - the rear caliper is heavier than the front due to the motor EPB.

3. Replacing pads:

   Remove the old pads and clean the guides. Install new ones by lubricating the back side. On X-Trail T31 rear pads have asymmetrical shape - do not confuse left and right!

4. Recessing the piston:

   Rotate the piston clockwise (viewed from the caliper side) while pushing down on it. To do this, use a special tool or pliers with flat jaws. If the piston does not rotate, check whether the service mode is activated EPB.

5. Assembly and calibration:

   Install the caliper in place, tighten the bolts to a torque 30–35 Nm and put on the wheel. After replacing the pads on both wheels, connect the scanner and perform EPB calibration (menu Brake system → EPB → Reset).

If you don't have a scanner, you can try to trick the system:

1. Turn on the ignition, but do not start the engine.
2. Press and hold the brake pedal.
3. Activate and deactivate the handbrake 3-5 times in a row.
4. Turn off the ignition, wait 10 seconds and repeat the procedure.

In 70% of cases this resets the error EPB, but there is no guarantee.

What should I do if the EPB is not calibrated?

If after replacing the pads the handbrake does not work or the light is on EPB on the panel, check:

1. Correct installation of the pads (they should fit tightly, without distortions).

2. Motor wiring condition EPB (wires often fray).

3. Presence of errors in the control unit (a scanner is needed to reset).

If the problem remains, the caliper motor may have failed (part number 40527-4M000 for X-Trail T31).

After replacing rear pads Be sure to check the operation of the handbrake:

• 🚗 Turn off the engine and pull the handbrake 5–7 clicks.
• 🔧 Try to move the car forward/backward - the wheels should be locked.
• 📏 Measure the lever stroke: if it is more than 8 clicks, adjustment is required.

Common mistakes when replacing pads and how to avoid them

Even experienced mechanics sometimes make mistakes that lead to squeaking, uneven wear, or brake failure. Here are the most common:

• 🔧 Unlubricated guides: if not applied copper paste on the caliper fingers, they will turn sour and the pads will jam. Symptom: overheating of the wheel after a trip.
• 🔩 Overtightened bolts: the caliper mounting torque should be 30–35 Nm. If you overtighten, the thread will break, and if you undertighten, the caliper will “walk”.
• 🔄 Incorrect running-in: new pads require a gentle regime for the first 200 km. Avoid sudden braking to allow the friction material to rub in evenly.
• 🔊 Ignoring the squeak: If the pads squeak after replacement, this is not always a defect. But if the sound does not disappear after 100 km, check the presence anti-squeak plates (they come with some pads).
• 🚫 Forgotten brake fluid: When the piston is retracted, the liquid rises in the tank. If you don't release it, when you press the pedal it will overflow.

Another common problem is uneven pad wear. Reasons:

• 🔧 Stuck caliper (the guides need to be cleaned and lubricated).
• 🔩 Bent brake disc (needs to be grooved or replaced).
• 🚗 Malfunction EPB (on the rear axle).

If after replacing the pads the car pulls to the side when braking, check:

• 🔧 Correct installation of the pads (they must be the same on both sides).
• 🔩 Condition of the brake hoses (if damaged, the pressure is distributed unevenly).
• 📏 Runout of brake discs (permissible value - no more than 0.05 mm).

On X-Trail T31 with all-wheel drive (4WD) pay attention to condition of wheel bearings. When they wear out, they produce play, which is mistaken for a problem with the brakes. Check the play by shaking the wheel in a vertical plane.

Running in new brake pads and caring for them

New pads required running-in — the process of grinding friction material to the disk. If you ignore this step, the braking performance will be worse and wear will accelerate. Follow this algorithm:

1. First 200 km:

   Avoid sudden braking. Brake smoothly, with no more than 50% of the maximum force. This will help distribute the friction layer evenly.

2. Next 300 km:

   Gradually increase the load. Perform 5-6 smooth brakes from a speed of 80-60 km/h at intervals of 1-2 minutes.

3. After 500 km:

   The pads are completely worn in. Now you can brake as normal.

During this period, avoid:

• 🚗 Long-term braking (for example, on descents) - this overheats the pads.
• 🚧 Driving through puddles immediately after intense braking - a sharp temperature change can cause disc deformation.
• 🔧 High pressure wheel washes - water should not get on the brake mechanisms.

To extend pad life:

• 🧴 Once every 10 thousand km, clean the calipers from dirt and lubricate the guides.
• 📏 Monitor the thickness of the discs - if it is close to the minimum, replace them along with the pads.
• 🚗 Avoid holding the brake pedal for a long time at traffic lights - this leads to local overheating.

If you have installed ceramic pads, please note that they require a longer break-in period (up to 800 km) and may brake worse at low temperatures. But they practically do not wear out the discs and do not generate dust.

Frequently asked questions (FAQ)

Is it possible to change the pads on only one wheel?

No, pads are always replaced in pairs on the same axle (front or rear). Otherwise, the braking force will be distributed unevenly, which will lead to skidding when braking. An exception is if the pad is mechanically damaged (for example, a piece of friction material has broken off).

How often should I check the brake pads on the X-Trail T31?

The manufacturer recommends inspecting the pads every 15 thousand km or once a year. However, if you often drive around the city with heavy braking, check them every 10 thousand km. Look for squeaks, vibrations, or extended braking distances as these are signs of wear.

What should I do if the squeaking does not go away after replacing the pads?

Creaking can be caused by several reasons:

• 🔧 Lack of anti-squeak plates (they come complete with some pads).
• 🔩 Dirt getting between the pad and the disc (needs to be cleaned).
• 📏 Low-quality friction material (cheap pads often squeak).
• 🚗 Incorrect running-in (the first 200 km need to be slowed down smoothly).

If the squeaking does not go away after 500 km, try applying anti-squeak paste on the back of the pads.

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

Pumping is only needed in two cases:

1. If you have disconnected the brake hoses.
2. If, when retracting the piston, brake fluid spills out of the reservoir and air enters the system.

In other cases, it is enough to press the brake pedal several times until the pistons are in the working position.

Is it possible to replace the pads on an X-Trail T31 with EPB yourself without a scanner?

Technically yes, but it's risky. Without a scanner, you will not be able to enter the caliper into service mode, and the piston will not sink. Alternative methods (disconnecting the battery, manipulating the handbrake) do not always work. If you don’t have a scanner, it’s better to contact a service center or borrow a tool from a friend.
