Original articles of rear brake pads for Nissan Pathfinder R51

Factory pads from Nissan guarantee 100% compatibility with the brake system Pathfinder R51, but their price often forces owners to look for alternatives. Below is a current list of article numbers for different years of manufacture and modifications:

• 🔧 40520-4M000 - original pads for most versions R51 (2005–2012), including models with engines VQ40DE (4.0 l) and VQ25DE (2.5 l). Suitable for vehicles without system VDC.
• 🔧 40520-4M001 — updated version for restyled Pathfinder (2010–2012), often equipped with a wear indicator.
• 🔧 40520-4M010 - pads for versions with VDC (stability control system). They differ in the composition of the friction material for better performance with ABS.
• 🔧 D4052-4M000 — kit for rear brakes with extended service life (often installed on export versions for the Middle East).

Important: articles may be duplicated in catalogs Nissan And Infiniti (For example, 40520-4M000 also suitable for Infiniti QX4 2003–2006). When purchasing, check availability certificate of conformity - counterfeits of the original are often found on the market.

⚠️ Attention: Pads with article number 40520-4M010 incompatible with earlier versions Pathfinder R51 (until 2008), as they have a different wear sensor profile. Their installation may lead to false alarms of the indicator on the dashboard.

The best analogues of the original pads: comparison of brands

If the original pads seem too expensive (their price reaches 8,000–10,000 rubles per set), it is worth considering analogues from trusted manufacturers. We analyzed owner reviews Pathfinder R51 and tests by independent experts to rank the best alternatives:

Brand	Article	Average price (per set)	Features	Rating (out of 5)
Akebono	ACT907A	5 200–6 500 ₽	Non-asbestos composition, low dust level, soft operation	4.9
Brembo	P 85 020	6 000–7 300 ₽	Increased service life (up to 60,000 km), optimized for aggressive driving	4.8
TRW	GDB1446	4 500–5 800 ₽	Good compatibility with VDC, average noise level	4.6
Ferodo	FDB1446	3 800–4 900 ₽	Budget option, suitable for a relaxed driving style	4.4

Critical moment: pads Akebono ACT907A have a unique friction material composition that minimizes wear of brake discs. This is especially important for Pathfinder R51 with a mileage of 150,000 km, where the discs are often already worn out.

When choosing analogues, pay attention to:

• 📌 Certification (must meet standards ECE R90 or FMVSS 135).
• 📌 Presence of wear sensor (if it is provided in your version).
• 📌 Material composition (non-asbestos pads last longer but may be more expensive).

How to determine rear pad wear on Pathfinder R51

Rear brake pads on Nissan Pathfinder R51 wear out more slowly than the front ones (on average 1.5–2 times), but their condition requires no less close attention. Main signs of wear:

• 🚨 Creaking or whistling when braking (especially at low speeds).
• 🚨 Increased brake pedal travel or its vibration.
• 🚨 The pad wear indicator lights up on the dashboard (if a sensor is installed).
• 🚨 Visible output (friction material thickness less than 3 mm).

For an accurate diagnosis:

1. Raise the car on a lift or use a jack (be sure to secure the wheels with chocks!).
2. Remove the rear wheel and inspect the pads through the inspection window in the brake caliper.
3. Measure the thickness of the friction layer with a caliper. Minimum permissible thickness - 2 mm (but replacement at 3mm is recommended).

⚠️ Attention: On Pathfinder R51 with the system VDC Worn rear pads can cause false alarms ABS when braking on uneven roads. This is due to a change in the gap between the pad and the disc, which confuses the system sensors.

What to do if new pads squeak?

The creaking of new pads in the first 200–300 km is normal (they rub against the disc). If the sound does not disappear for longer, check:

- Quality of installation (perhaps the caliper guides are not lubricated).

- Compatibility of pads with discs (for example, Brembo may squeak with original discs Nissan).

- Presence of anti-squeak plates (their absence is a common cause of post-warranty problems).

Step-by-step instructions for replacing rear pads

Replacing rear pads with Pathfinder R51 more difficult than on the front ones, due to the integrated parking brake (if it is drum type). Below are universal instructions for versions with disc brakes rear (most trim levels after 2007).

Required tools:

• 🔧 Set of sockets and ratchet wrench (size 14 mm And 17 mm).
• 🔧 Special puller for caliper pistons (or clamp with adapter).
• 🔧 WD-40 or similar penetrating lubricant.
• 🔧 Copper grease for guides.
• 🔧 Torque wrench (preferably, but not required).

Work order:

1. Loosen the rear wheel nuts, jack up the car and remove the wheel.
2. Unscrew the two caliper mounting bolts (usually 14 mm).
3. Remove the caliper and hang it on a wire (do not let it hang on the brake hose!).
4. Remove the old pads and clean the seats from dirt.
5. Press the caliper piston using a puller (rotate it clockwise, as it Pathfinder R51 a threaded mechanism is used).
6. Install new pads, lubricate the caliper guides and reassemble everything in reverse order.

- Check the brake fluid level (it will rise when the piston is pushed in)

- Buy new caliper guides (it is recommended to change them together with the pads)

- Prepare a jack and stops (at least 2)

- Clean brake discs from rust (use a special cleaner)

Tightening torques:

• Caliper bolts: 30–35 Nm.
• Wheel nuts: 100–120 Nm.

⚠️ Attention: On versions with VDC after replacing the pads it may be necessary brake adaptation reset via a diagnostic scanner (for example, Launch X431). Without this ABS may not work correctly for the first 50–100 km.

Compatibility of pads with different versions Pathfinder R51

One of the main difficulties when selecting pads for Nissan Pathfinder R51 — a variety of brake systems depending on the year of manufacture and the sales market. Below are the key differences:

Year of manufacture	Engine	Rear brake type	Recommended article
2005–2007	VQ40DE (4.0 l)	Disk (without VDC)	40520-4M000 or ACT907A (Akebono)
2008–2010	VQ25DE (2.5 l)	Disk (+VDC)	40520-4M010 or GDB1446 (TRW)
2011–2012	All engines	Disc (+wear sensor)	40520-4M001 or P 85 020 (Brembo)

Features:

• 🔹 On cars for USA and Canada (market code USA) pads with an increased friction layer were often installed (article no. D4052-4M000).
• 🔹 For versions with all-wheel drive (4WD) pads with a higher friction coefficient are recommended (for example, Brembo P 85 020).
• 🔹 Restyled models (after 2010) may require replacement anti-squeak plates (article 40528-4M000).

Common replacement mistakes and how to avoid them

Even experienced car owners make mistakes when replacing rear pads with Pathfinder R51, which leads to premature wear or incorrect operation of the brakes. Let's look at the most common ones:

1. Incorrect installation of anti-squeak plates.

   Plates must be installed friction side to the block. A mixed position leads to squeaking and vibrations.

2. Ignoring the condition of the caliper guides.

   Soured guides are the main cause of uneven pad wear. They need to be cleaned and lubricated special high temperature lubricant (For example, Slipkote 220-R DBC).

3. Failure to follow the caliper tightening order.

   Caliper bolts are tightened criss-cross with effort 30–35 Nm. Failure to comply with the torque leads to misalignment and accelerated wear.

4. They forget to bleed the brakes after replacing them.

   After retracting the caliper piston, you need to press the brake pedal several times to get the pads into place. Otherwise, the braking distance will be increased during the first 100 km.

Critical error: using conventional lubricant (for example, Litola) for caliper guides. When heated, it loses its properties, which leads to caliper jamming and uneven braking.

FAQ: Frequently asked questions about rear pads Nissan Pathfinder R51

Is it possible to put front pads on the rear axle?

No, this is strictly prohibited. Front and rear pads on Pathfinder R51 They have different shapes, friction material composition and contact area with the disc. Installing front pads at the rear will result in:

• Incorrect operation ABS And VDC.
• Accelerated wear of brake discs.
• Increased risk of skidding when braking.

How often do you need to change your rear pads?

Rear pad service life Pathfinder R51 depends on driving style and operating conditions:

• Quiet driving (city/highway): 60,000–80,000 km.
• Aggressive driving/mountain roads: 30,000–50,000 km.
• Operation with a trailer: 20,000–40,000 km.

It is recommended to check the thickness of the pads every 15,000 km or when changing tires seasonally.

What to do if the light comes on after replacing the pads ABS?

This is a typical problem for Pathfinder R51 with the system VDC. Causes and solutions:

1. Brake adaptation has not been reset. You need to perform a reset procedure using a diagnostic scanner (for example, Launch CReader).
2. The pad wear sensor is damaged. Check the integrity of the wiring and connector.
3. The pads are not installed correctly. Recheck the position of the anti-squeak plates and clearances.

If the light does not go out after resetting, contact a service station for diagnostics. ABS.

Which pads are best for off-road?

For operation Pathfinder R51 in off-road conditions (mud, sand, water), pads with:

• Increased heat resistance (For example, Brembo P 85 020).
• Reinforced anti-corrosion coating (series Akebono ProACT).
• Aggressive friction material (For example, Ferodo Premier), but they wear out the discs faster.

Avoid pads with a high metal content - they perform worse when wet.

Is it possible to drive if only one pad wears out?

No! Uneven wear of the pads on one axle (for example, the left one is worn out, but the right one is not) is a sign of a serious malfunction:

• Jammed guide caliper.
• Damaged brake hose (does not allow liquid to pass through).
• Curved brake disc.

Operation in this condition leads to:

• Car skidding when braking.
• Overheating and deformation of the brake disc.
• Refusal VDC And ABS.

It is urgent to diagnose and eliminate the cause!
