Nissan Sunny FB15 - a reliable sedan that has gained popularity due to the balance of price, quality and efficiency. But even the most durable car requires attention to the braking system. Brake pads are a consumable item, the condition of which determines not only comfort, but also safety. In this article we will look at how to choose suitable pads for FB15when to change them, and what nuances to consider when replacing them.
Model Sunny FB15 (2010–2017) was equipped with disc brakes on all wheels, which simplifies the selection of spare parts. However, even within the same generation there are differences: for example, pads for versions with engines HR15DE (1.5 l) and MR20DE (2.0 l) may differ in the composition of the friction material. Not to mention the fact that original parts from Nissan and analogues from Brembo or TRW behave differently on the road.
We analyzed owner reviews, technical data and service center recommendations to put together the most useful guide. Without water - only specific advice, comparisons and instructions.
Signs of brake pad wear on a Nissan Sunny FB15
The first signal that the pads require replacement is creaking or squealing when braking. This works by a wear indicator (a metal plate) that begins to rub against the disc when the friction layer wears down to a critical level. On FB15 These indicators are installed on the front pads from the factory.
Other symptoms:
- 🔴 Increased braking distance — the car stops slower, the pedal has to be pressed harder.
- 🔴 Vibration or beat on the steering wheel when braking - a sign of uneven wear of the pads or deformation of the discs.
- 🔴 Black dust on rims - the norm for ceramic pads, but if there is too much of it, this may indicate accelerated wear.
- 🔴 Moving the machine to the side when you press the brake, one of the pads may be worn out more or the caliper may be jammed.
On the Sunny FB15, the rear pads wear out 1.5–2 times slower than the front ones due to lower load, but their condition needs to be checked every 20–30 thousand km. If these signs are ignored, the consequences can be serious, ranging from damaged brake rotors to complete brake failure.
⚠️ Attention: If, after replacing the pads, the brake pedal becomes “soft” or falls out, immediately check the brake fluid level and the tightness of the system. On FB15 this may indicate a faulty master cylinder.
Original vs analogues: what to choose for FB15?
Original pads from Nissan (article 40520-4M000 for front and 40520-4M010 for the rear ones) guarantee compatibility and predictable behavior, but their price is often steep - from 3,500 to 5,000 rubles. per set. Alternatives from trusted brands can save you up to 40% without sacrificing quality.
Let's compare popular options:
| Brand | Article (front) | Material | Service life (thousand km) | Features | Price (set, rub.) |
|---|---|---|---|---|---|
| Nissan (original) | 40520-4M000 |
Semi-metallic | 40–50 | Minimal disc wear, low noise level | 4 800–5 200 |
| Brembo | P24064 |
Ceramics | 50–60 | Less dust, but may squeak at low temperatures | 3 200–3 600 |
| TRW | GDB1465 |
Low metal | 45–55 | Good price/quality balance, suitable for aggressive driving style | 2 800–3 100 |
| Akebono | ACT907A |
Ceramics | 55–65 | Almost dust-free, but more expensive than analogues | 4 000–4 500 |
| Bosch | 0986494619 |
Semi-metallic | 40–50 | Budget option, but may wear out discs faster | 2 200–2 500 |
For Sunny FB15 with engine HR15DE (1.5 l) ceramic pads are better suited - they are softer on the discs and generate less dust. For MR20DE (2.0 l) it is worth considering low-metallic or semi-metallic options, as they better cope with the loads of dynamic driving.

When to change pads: regulations and real terms
According to the regulations Nissan recommends checking brake pads every 15,000 km, and replacing them when the friction material wears down to 2–3 mm. However, the actual timing depends on several factors:
- 🚗 Driving style: In a city with frequent stops, the pads wear out 2 times faster than on the highway.
- 🏔️ Operating conditions: in mountainous areas or when towing a trailer, the load on the brakes increases by 30–40%.
- 🌡️ Quality of materials: cheap pads can be washed in 10–15 thousand km, while premium ones (for example, Akebono) serve up to 70 thousand km.
- 🔧 Caliper condition: A jammed piston or guides accelerates pad wear by 3–5 times.
In practice for Sunny FB15 average replacement interval for front pads - 30–40 thousand km, rear - 60–80 thousand km. But these numbers may vary. For example, if you often drive along serpentine roads or use your car in a taxi, the pads may wear out after 20 thousand km.
Before winter, check the condition of the brake pads - moisture and salt on the roads accelerate corrosion of the calipers and increase the load on the brake system.
Step-by-step instructions for replacing pads on a Nissan Sunny FB15
Replacing brake pads with FB15 does not require special equipment, but will require accuracy and consistency. Here's what you'll need:
- 🔧 Set of keys (12, 14, 17 mm)
- 🔧 Jack and stops
- 🔧 Brake pad puller (or screwdriver)
- 🔧 Brake fluid
DOT-4(for topping up) - 🔧 Copper grease for guides
- 🔧 Gloves and protective equipment (dust from pads is harmful!)
Sequence of actions:
Raise the car on a jack and remove the wheel. Be sure to secure the car with supports! On FB15 It's best to start with the front right wheel.
Unscrew the lower caliper bolt (14 mm wrench), then the upper one (12 mm wrench). Carefully hang the caliper on a wire or a special hook so as not to damage the hose.
Remove the old pads. If they are stuck, use a puller or carefully pry them off with a screwdriver. Clean the guides and seats from dirt.
Install new pads, first applying a thin layer of copper grease to the back of them (but not to the friction material!).
Press the caliper piston back using a puller or an adjustable wrench. On FB15 this can be done manually, but it will require some effort.
Reassemble everything in reverse order. After replacing, press the brake pedal several times to ensure the pads are in place.

⚠️ Attention: If after replacing the pads the car pulls to the side when braking, check:
- The pads are installed correctly (left/right sides are not mixed up).
- The condition of the brake discs may require resurfacing or replacement.
- Caliper performance - a stuck piston or guides can cause uneven braking.
Subtleties that are not discussed in manuals
Even experienced craftsmen sometimes miss the nuances that affect the durability of the pads and braking comfort. Here's what's important to know for Sunny FB15:
Proper running in of new pads. For the first 200–300 km, avoid sharp braking - the friction material should “get used” to the disc. This is especially important for ceramic pads (Brembo, Akebono), which require longer running-in.
Lubricating the caliper guides. On FB15 Often people forget to lubricate the guides, which causes the pads to wear unevenly. Use only high temperature grease (For example, Slipkote 220-R DBC).
Checking the brake hoses. If the hoses become stiff or cracked, the caliper may not fully move away from the disc, which leads to overheating and accelerated pad wear.
Monitoring the condition of brake discs. If the discs have deep grooves (more than 0.5 mm) or runout, new pads will last 2 times less. In this case, the discs need to be sharpened or replaced.
What happens if you don't change your brake pads on time?
When the friction material is critically worn, the metal base of the pad begins to rub against the brake disc, which leads to:
- Damage to the disc (deep grooves, deformation).
- Increased braking distance by 2–3 times.
- Overheating of the caliper and risk of piston jamming.
- Increased load on the brake system, which can damage the master cylinder.
On Sunny FB15 this is especially critical since the braking system here is not designed for extreme loads (unlike, for example, Nissan GT-R).
On FB15 with automatic transmission, brake pads wear out faster than on versions with manual transmission, due to more frequent use of the brakes when driving in traffic jams. If you operate the car mainly in the city, reduce the interval for checking the pads to 10 thousand km.
Common mistakes when replacing pads and how to avoid them
Even a simple procedure for replacing pads can turn into problems if you make mistakes. This is what happens most often on Sunny FB15:
- 🔧 Incorrect installation of springs or brackets. On the rear pads FB15 There are small spring clips - if they are not installed or twisted, the pads will dangle and wear out quickly.
- 🔧 Ignoring the caliper state. If you don't clean the guides or replace damaged boots, the caliper may jam and the pads will constantly rub against the disc.
- 🔧 Using low quality lubricant. Regular lithol or graphite lubricant does not withstand high temperatures and can boil, which will lead to the pads sticking.
- 🔧 Incorrect bolt tightening torque. Overtightened caliper bolts can deform the brake disc, and loose caliper bolts can cause vibration.
Another common mistake is failure to bleed brakes after replacing pads. On FB15 This is not always necessary, but if you notice that the pedal has become soft, be sure to check the system for air. To bleed, you will need an assistant or a special tool (for example, a vacuum pump).
After replacing the pads, be sure to check the ABS operation! On Sunny FB15 Malfunctions in the brake system can cause false activation of the anti-lock braking system, especially on slippery roads.
Replacement cost: do it yourself or go to a service center?
If you decide to replace the pads yourself, your costs will be limited to the cost of spare parts and consumables (lubricant, brake fluid). On average it will cost 2,500–5,000 rub. per set (front + rear) depending on the brand.
The price for the service will be higher:
| Service type | Cost of work (rub.) | Lead time | Pros | Cons |
|---|---|---|---|---|
| Official dealer Nissan | 3 500–5 000 | 2–3 hours | Warranty, original spare parts, diagnostics | Expensive, long |
| Third party service | 1 500–2 500 | 1–1.5 hours | Cheaper, you can choose a specialist | Quality depends on service |
| Mobile master | 2 000–3 000 | 1.5–2 hours | No need to go to the service center, convenient | Limited tool |
Replacing it yourself will save money, but requires time and care. If you are not confident in your skills, it is better to contact a service center - especially when it comes to the rear pads, where there are nuances with the hand brake.
On Sunny FB15 with electric power steering (EPS) After replacing the pads, it may be necessary to reset the brake system adaptations. This can be done using a diagnostic scanner (for example, Launch X431) or through several braking cycles with different intensities.
FAQ: Answers to frequently asked questions about Nissan Sunny FB15 brake pads
Is it possible to install pads on only one axle (for example, only the front ones)?
No, this is absolutely not recommended. The pads are always changed in pairs on the same axle (left + right), otherwise the braking force will be distributed unevenly, which will lead to the car pulling to the side when braking. An exception is if you replace only one pad from a pair (for example, due to mechanical damage), but even in this case it is better to change both.
Which brand of pads is better to choose for city driving?
For urban use, ceramic pads are optimal (Brembo, Akebono), since they generate less dust and last longer with frequent braking. If your budget is limited, you might consider TRW — they perform well in a metropolitan environment.
Do I need to change brake discs and pads?
Not always. If the discs do not have deep grooves (more than 0.5 mm), cracks or runout, they can be left. However, if the disk thickness is close to the minimum allowable (indicated on the disk itself), it is better to replace them along with the pads. On FB15 The minimum thickness of the front discs is 19 mm, the rear discs are 8 mm.
Why did a squeak appear after replacing the pads?
Creaking can occur for several reasons:
- Running in new pads (must pass after 100–200 km).
- Low-quality friction material (especially for cheap pads).
- Dirt or grease getting on the working surface of the pads.
- Incompatibility of pads and discs (for example, semi-metallic pads with drilled discs).
If the squeaking persists, try cleaning the pads and discs with a special cleaner (Brembo Cleaner), and then gently rub them in.
Can I use pads from other Nissan models on the Sunny FB15?
Sometimes yes, but with reservations. For example, front pads from Nissan Note E12 (article 40520-4M000) are also suitable for FB15, since the platforms of these models are related. However, rear pads from other models (for example, Almera N16) are not compatible due to different caliper sizes. Always check catalogs by VIN code.
