SUV operation Nissan Pathfinder The R51, in Russian off-road and city traffic conditions, places increased demands on the safety system. The braking system of this car experiences enormous loads, especially when towing trailers or driving along mountain serpentines. That is why the condition brake pads is a critical factor in your safety on the road.
Many owners ignore early signs of wear until they hear a characteristic squeak or notice a decrease in braking performance. However Nissan Pathfinder - a heavy car, and the safety margin of its brakes should be maximum. The original front pads on the R51 have a working layer thickness of 16 mm, which provides a range of up to 40,000 km with moderate use. Timely diagnosis and replacement will avoid costly repairs of calipers and discs.
Design features of the R51 brake system
Brake system Nissan Pathfinder the second generation (R51) is built according to the classical scheme, but has its own nuances that affect the choice of consumables. Large-diameter ventilated discs are installed at the front, which allows for efficient heat dissipation during heavy braking. Disc brakes are used at the rear, although some early trim levels feature drum brakes, which require special attention when selecting spare parts.
The key is to have a system ABS and EBDwhich require precise operation of brake cylinders and pads. Any misalignment or uneven wear can lead to errors in the operation of the electronic stabilization systems. Therefore, when replacing, it is important to strictly observe the installation geometry and the tightening torque of fasteners.
Owners often face the problem of quickly contaminating the brake system with dust from the pads. This is especially true for budget analogues that use soft friction material compositions.
The presence of a wear sensor on the front pads is standard for most trim levels. If you hear a metallic grinding sound when you lightly touch the pedal, this is a signal that friction lining wear reached a critical level.
Original spare parts and their analogues
The choice between original parts and high-quality analogues is an eternal dilemma for owners of Japanese cars. Nissan recommends using pads with article number 41060-1YV0A for the front axle and 41060-1YV0B for the back. Original products are characterized by a stable friction coefficient and low noise level, but their cost is often inflated due to the brand.
There are many worthy substitutes on the market, which often surpass the original in terms of resource. Brands specializing in Japanese cars offer excellent friction material compositions adapted for heavy SUVs. It is important to pay attention to the packaging and the presence of holographic protective stickers, since there are a lot of fakes on the market.
- 🏎️ TRW - German quality, excellent price-to-braking ratio.
- 🛡️ ATE — premium segment, ideal for aggressive driving style.
- 🇯🇵 Nisshinbo - Japanese manufacturer, often placed on the conveyor, soft and silent operation.
- 🔧 Textar is a reliable European brand with a wide range of products for the R51.
You should not save on brakes by buying products from unknown Chinese brands without certificates. Cheap pads often lead to overheating of the discs and their deformation, which ultimately costs more than purchasing quality spare parts.
When choosing an analogue, always check that the kit contains the necessary brackets, springs and lubricant, since original repair kits are often sold separately, which increases the cost of the repair process.

Wear symptoms and diagnosis
Determine the need for replacement brake pads This can be done not only by the wear sensor, but also by a number of indirect signs that are often ignored by drivers. One of the very first signals is a change in the nature of braking: the pedal becomes less responsive, or, conversely, vibration appears when pressed. This may indicate uneven wear or warping of the disc due to overheating.
A visual check through the wheel rim allows you to assess the remaining thickness of the friction layer. If the thickness of the pad is less than 3 mm, operation becomes dangerous. In some cases, wear is accompanied by a characteristic whistle, which occurs due to the fact that the metal base of the pad begins to touch the brake disc.
Particular attention should be paid to the condition of the guide supports. Soured guides cause the pad to not move away from the disc, causing constant overheating and rapid wear.
If you smell something burning after a ride, this is a sure sign that brake pads overheated or jammed. In such a situation, you must immediately stop the car and let the system cool down without trying to pour water on the discs.
Replacement process and necessary tools
Replacing the pads with Nissan Pathfinder R51 is a task of medium complexity that can be handled by an experienced car enthusiast with a minimum set of tools. You will need a jack, a wheel wrench, a set of sockets and wrenches, and a special tool for pressing in the caliper piston. Be sure to have brake cleaner and high-temperature lubricant ready.
The process begins by removing the wheel and inspecting the condition of the caliper. It is necessary to remove dirt and rust from the seats so that the new pad will fit smoothly. After this, you need to unscrew the lower bolt of the caliper guide, move it to the side and remove the old pads.
☑️ Replacement tools
When installing new pads, it is important to check the condition of the piston boots. If they are torn, moisture and dirt will enter the mechanism, causing corrosion and jamming. In this case, replacing the anthers is mandatory.
After installing all the elements, you need to press the brake pedal all the way down several times so that the pistons fall into place and you do not drive on an empty pedal. This is a critical step that should not be skipped.
Common mistakes when replacing
Improper installation of the wear sensor may result in false alarms or no signal. It is also important not to confuse the inner and outer pads, as they may have different geometries or the presence of a sensor.
Article table and compatibility
For ease of selection of spare parts, below is a summary table with the main articles that are suitable for various modifications Nissan Pathfinder R51. Please note that there may be size differences between diesel and petrol versions so always check the VIN before purchasing.
| Brake type | Original number | Analogue (TRW) | Analogue (ATE) |
|---|---|---|---|
| Front | 41060-1YV0A | GDB1307 | 13.0460-5362.2 |
| Rear (disc) | 41060-1YV0B | GDB1308 | 13.0460-5363.2 |

| Guide kit | 41060-1YV0D | GDB1310 | 13.0460-5365.2 |
When ordering spare parts from catalogs, be sure to check the year of manufacture of the car, since in the middle of production of the R51 model there may have been minor changes in the design of the calipers. An error in the article will result in the pads simply not fitting into place or touching the suspension elements.
Before purchasing, measure the thickness of the old pads with a caliper and compare them with the stated characteristics of the new ones. This will help avoid purchasing incompatible parts with different friction layer thicknesses.
Recommendations for operation and running-in
After installing new brake pads it is necessary to carry out a running-in procedure. This is the process by which the friction material adapts to the surface of the brake disc. Without proper lapping, braking performance can be reduced by 20-30%, and the life of the pads will be reduced.
During the first 200-300 km, avoid sudden and extreme braking. Try to brake smoothly without overheating the system. This will allow the friction layer to be evenly distributed across the disc, ensuring maximum contact. Sudden stops at this stage may result in disc staining and vibration.
- 🛑 Avoid prolonged braking in mountainous areas without breaks.
- ❄️ Do not wash your wheels and brakes with hot water immediately after an intense ride.
- 🔍 Check the brake fluid level regularly, as when the pads wear, the pistons move out, increasing the volume of working fluid in the system.
If you use ceramic pads, the breaking-in process may take longer, but they provide more consistent braking at high temperatures.
Proper running-in of new pads directly affects their service life and braking safety in emergency situations. Neglecting this step can lead to rapid failure of the entire braking system.
⚠️ Attention: Never use expired brake fluid. The hygroscopicity of the fluid causes moisture to enter the system, which lowers the boiling point and can cause brake failure under heavy load.
Frequently asked questions from owners
How long do the original pads last on the Nissan Pathfinder R51?
On average, original front pads last from 30 to 45 thousand kilometers, rear pads - up to 60 thousand. However, the actual resource greatly depends on the driving style, the quality of the road surface and operating conditions (city or highway).
Is it possible to change only the front pads?
Technically it is possible, but it is recommended to change the pads on one axle at once (both wheels). This will ensure uniform braking and prevent the car from skidding during an emergency stop.
Why do new pads squeak?
The squeaking noise can be caused by insufficient running-in, lack of lubrication on the metal parts of the pad, or dirt getting between the pad and the caliper. This may also be a sign of poor quality friction material.
Do I need to wipe brake discs when replacing pads?
Yes, definitely. Discs must be cleaned of dust and dirt with a special cleaner. If the discs have deep marks or grooves, it is better to replace or sharpen them, since the new pad will not be able to provide proper contact with the uneven surface.
