Front brake pads for Nissan Almera Classic: selection, replacement and operating nuances

Nissan Almera Classic (known in some countries as Samsung SM3) is one of the most popular sedans in the budget segment, valued for its reliability and ease of maintenance. However, even such an unpretentious car has components that require regular attention - and the brake system comes first here. Front brake pads wear out 2–3 times faster than the rear ones due to increased load, and their malfunction directly affects safety.

In this article we will look at how choose the right pads for Almera Classic (body B10, 2006–2012), what to look for when buying, when to change them, and how to replace them yourself. We will also discuss unique features of the braking system of this model, which are often overlooked even by experienced car owners.

Signs of wear on the front brake pads on a Nissan Almera Classic

Brake pads do not fail suddenly; their wear appears gradually. The main thing is not to miss the moment when replacement becomes critical. For Almera Classic with engines 1.4 And 1.6 (models K4M And HR16DE) the following symptoms are characteristic:

• 🔊 Creaking or whistling when braking - the most obvious sign. On the blocks Almera Classic often installed wear indicators (metal plates) that begin to make sound when the friction layer remains thick 2–3 mm.
• 🚗 Increased braking distance. If the car begins to slow down worse, and the brake pedal “sinks” deeper than usual, this is a signal that the pads have worn down to metal or the brake fluid needs to be replaced.
• 🔥 Vibration or beat on the steering wheel when braking. Most often caused uneven pad wear or deformation of brake discs (relevant for Almera Classic after 100 thousand km).
• 💨 Dust on wheels. Abundant black deposits are the norm for new pads, but if there is significantly more dust, this may indicate destruction of the friction material.

Feature Almera Classic: due to the design of the calipers (single piston on most versions) Inner pads wear out faster than outer ones. Therefore, when inspecting, you need to check both sides.

⚠️ Attention! If cracks, chips appear on the pads or the friction layer has become thinner 1–1.5 mm, they need to be changed immediately — further operation will lead to damage to the brake discs, which is 3–4 times more expensive to repair.

Which pads are suitable for Nissan Almera Classic (B10)?

For Nissan Almera Classic (2006–2012) front brake pads are selected according to the following parameters:

• 📏 Size: length 114.3 mm, width 55.6 mm, thickness 16.5 mm (new). These parameters are unified for all versions with engines 1.4 And 1.6.
• 🔧 Mounting type: pads are fixed spring clips (clips), so it is important that the kit includes new guides and anti-squeak plates.
• 🔍 Original article number: 40520-9M000 (for versions before 2010) and 40520-BM400 (for restyled models). Supplies original pads Nissan, but their prices are often overpriced.

Among the analogues, the most popular are:

Brand	Article	Features	Average price (set)
TRW	GDB1446	High quality friction material, low dust level, suitable for aggressive driving style.	1 800–2 200 ₽
Bosch	0 986 494 219	Optimal price/quality ratio, soft braking, but wear out faster with frequent city trips.	1 500–1 900 ₽
Ferodo	FDB4266	Moderate disc wear, suitable for quiet driving. Anti-squeak plates included.	1 600–2 000 ₽
ATE	13.0460-2834.2	Hard pads with a high coefficient of friction, recommended for cars with mileage >150 thousand km.	2 000–2 500 ₽
Sangsin	SP1446	Budget option, often installed on a conveyor Renault-Samsung. The average resource is 30–40 thousand km.	1 000–1 400 ₽

When choosing pads for Almera Classic consider:

• 🚘 Driving style: soft pads are suitable for the city (Bosch, Ferodo), for the track - more rigid (ATE, TRW).
• 🌡️ Operating conditions: in regions with frequent temperature changes (for example, Siberia), it is better to avoid pads with a high metal content - they can “drive” the discs.
• 🔄 Disc Compatibility: if the discs are already worn out (thickness <18 mm), you should not install aggressive pads - this will speed up their destruction.

When to change pads: regulations and real terms

According to the regulations Nissan, front brake pads on Almera Classic need to check every 15,000 km, and replacement should be carried out when the friction layer is worn to 2 mm. However, in practice, service life depends on several factors:

• 🛣️ Operating conditions:
  • In the city (frequent acceleration/braking) - 20–30 thousand km.
  • On the highway (even driving) - up to 50–60 thousand km.
• 🚗 Vehicle weight: Almera Classic with engine 1.6 and a loaded trunk wears out the pads on 15–20% faster.
• 🔥 Quality of materials: cheap pads (Frixa, LPR) can become dusty and wear off over 10–15 thousand km.

Critical Feature Almera Classic: on cars with ABS (anti-lock braking system), the pads wear unevenly due to frequent operation of the sensors. If you notice that one side is wearing out faster, check:

• Condition caliper guides (should move freely, without play).
• Performance caliper piston (there should be no jamming).
• Integrity guide boot (if damaged, dirt gets in, which leads to corrosion).

⚠️ Attention! If the brake pedal becomes soft after replacing the pads, this may indicate air entering the system or brake hose wear. In this case, bleeding of the brakes is required.

Step-by-step instructions for replacing front pads

Replacing brake pads with Nissan Almera Classic - a procedure that can be performed independently with a minimum set of tools. You will need:

• 🔧 Jack and stops (or lift).
• 🔨 Key set: at 14 (for guides), at 17 (for caliper).
• 🧲 Screwdriver with a flat blade (for bending the locking plates).
• 🧴Brake fluid DOT-4 (for topping up).
• 🧼 Brake cleaner (eg. LIQUI MOLY Bremsen-Reiniger).

Work order:

1. Raise the car on a jack and remove the wheel. Be sure to secure the machine with supports — Almera Classic has a high center of gravity, which is dangerous when working.

2. Unscrew the two caliper mounting bolts (wrench at 14). Carefully remove the caliper and hang it on a wire - do not allow sagging on the hose!

3. Remove the old pads. Clean the seats from dirt and rust. Check status anti-squeak plates - if they are worn out, replace them.

4. Press down the caliper piston. To do this, use a clamp or an adjustable wrench. Do not press the brake pedal with the caliper removed — the piston will fly out!

5. Install new pads and reassemble the caliper in reverse order. After assembly, press the brake pedal several times until the piston snaps into place.

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

Clean the caliper guides and lubricate them with special lubricant (for example, SLIPKOTE 220-R DBC)

Make sure that the new pads match the article number (check with the original 40520-9M000)

After replacement, do test braking at low speed (5-10 km/h)-->

Feature Almera Classic: on some versions (especially with ABS) it may light up after replacing the pads brake system fault indicator. This is due to the wear sensor, which sometimes breaks during dismantling. To reset the error, just:

1. Start the car.
2. Press the brake pedal 5–7 times at intervals of 1 second.
3. Turn off the ignition to 10 seconds and start the car again.

What to do if the caliper is soured and cannot be removed?

If the caliper guides Almera Classic rusty, do not hit them with a hammer - this will damage the threads. Instead:

1. Treat the bolts with a penetrating lubricant (for example, WD-40 Specialist) and wait 15–20 minutes.

2. Try to unscrew the bolts with an impact wrench (if available).

3. If that doesn’t help, heat the caliper with a heat gun (no higher than 200°C) to expand the metal.

4. As a last resort, cut the bolts with a grinder and install new ones (part number 40525-9M000).

Common mistakes when replacing pads and how to avoid them

Even experienced car owners make mistakes when replacing brake pads. Nissan Almera Classic. Here are the most common ones:

• 🔧 Unlubricated guides. If you do not apply special lubricant to the caliper pins, the pads will jam, which will lead to uneven wear and overheating of the discs. Use high temperature lubricants (For example, Molykote G-4500).
• 🚫 Ignoring the condition of the brake discs. Installing new pads on worn or warped discs (thickness < 19 mm, beating > 0.05 mm) reduces their resource by 30–50%.
• 🔄 Incorrect running-in. After replacing the pads, the first 200–300 km sharp braking should be avoided - the friction material should “grind in” to the disc.
• 💧 Grease getting on the pads. Even a small amount of oil or brake fluid on the working surface of the pads reduces braking efficiency by 40–60%.

Another common problem Almera Classic — souring of the caliper piston. If after replacing the pads the caliper does not return to its original position, this may indicate:

• Piston corrosion (caliper replacement or repair required).
• Damage to the boot (needs to be replaced, otherwise dirt will get inside).
• Wear of the o-ring (sign: brake fluid leakage).

How to extend the life of brake pads?

Average life of front pads Nissan Almera Classic — 30–50 thousand km, but with proper operation this figure can be increased to 60–70 thousand km. Here are some proven methods:

• 🚦 Smooth braking. Sharp pedal presses increase the load on the pads 3–5 times. Try to brake with the engine in lower gears.
• 🚿 Brake washing. After driving in mud or salt, clean the pads and discs with water (no detergents!). This will prevent corrosion and abrasive wear.
• 🔧 Regular caliper checks. Every 10 thousand km lubricate the guides and check the play. A jammed caliper can wear out the pads in 5–10 thousand km.
• 🌡️ Temperature control. Overheating of the pads (for example, after a long descent from a mountain) leads to their “hardening” and loss of efficiency. Let the brakes cool down.

For Almera Classic with ABS it is especially important to monitor sensor status. If the indicator on the dashboard comes on ABS, this may be due to:

• Damage to the sensor wiring.
• Accumulation of metal shavings on the sensor rotor (needs to be cleaned).
• ABS unit malfunction (diagnostics required).

⚠️ Attention! If you are using ceramic pads (For example, ATE Ceramic), remember that they require higher temperatures to brake effectively. In the urban cycle, their resource may be lower than that of their semi-metallic counterparts.

Is it worth saving on brake pads?

Price for pads Nissan Almera Classic varies from 800 ₽ (budget Sangsin) to 2 500 ₽ (premium TRW or ATE). Many car owners try to save money by buying cheap analogues, but this is fraught with:

• 🛑 Increased braking distance. Budget pads often have a low coefficient of friction, especially in the rain.
• 🔥 Overheating of disks. Cheap materials heat up faster, which leads to disc deformation and vibration.
• 🚗 Rapid wear. Pads Frixa or LPR may be erased over 10–15 thousand km, whereas TRW or Ferodo last 2–3 times longer.
• 💨 Heavy dusting. Low-quality pads leave a black coating on the discs that is difficult to clean.

However, overpaying for a brand is not always justified. For example, original pads Nissan (article 40520-9M000) are often repackaged Sangsin or Mando, but stand on 30–50% more expensive. The best option is middle price segment pads (Bosch, Ferodo), which offer the best price/quality ratio.

If you still decide to save money, pay attention to:

• Country of manufacture. Pads made in Korea or Japan are usually of better quality than Chinese ones.
• Availability of certificates (For example, ECE R90).
• Owner reviews Almera Classic — Specific items are often discussed on forums.

💡

Saving on pads is more expensive: cheap analogues wear out brake discs faster, the cost of which starts from 3 000 ₽ for a couple.

FAQ: Frequently asked questions about Nissan Almera Classic brake pads

Can the pads be placed on only one side?

No! Pads are always changed in pairs on the same axis (i.e. on both front wheels at the same time). Otherwise, the braking force will be distributed unevenly, which will lead to the car pulling to the side when braking. The exception is if the pads on one side are almost new (for example, after a recent replacement), and on the other they are worn out.

Which brand of pads is best for a quiet ride?

For the urban cycle with smooth acceleration and braking, the following are optimal:

• Bosch 0 986 494 219 — soft, little noise, but dusty.
• Ferodo FDB4266 - A good balance between comfort and durability.
• Textar 2463501 — low level of vibrations, suitable for cars with mileage >100 thousand km.

Avoid ceramic pads (For example, ATE Ceramic) - they are effective at high temperatures, but in the city they can slow down worse.

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

Brake bleeding required only in two cases:

1. If you have disconnected brake hoses or pipes.
2. If the brake pedal remains “soft” after replacing the pads (this indicates air has entered the system).

In other cases, it is enough to press the brake pedal several times to force the caliper pistons into place.

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

The creaking may remain for several reasons:

• The pads are not used (you need to drive 200–300 km).
• Missing or worn anti-squeak plates (needs to be purchased and installed).
• Low quality friction material (typical of cheap pads).
• Dirt gets between the pad and the deep seal (needs to be cleaned).

If the squeak does not disappear after break-in, try applying anti-squeak paste (For example, LIQUI MOLY Bremsen-Anti-Quietsch-Paste) to the back of the pads.

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

No! If one pad wears significantly faster than the other, this indicates caliper malfunction:

• Piston jamming.
• Worn or corroded guides.
• Damage to the boot.

Operation in this condition is dangerous: the braking force is distributed unevenly, which can lead to skidding or increasing braking distance. We urgently need to diagnose the caliper!
