Front brake pads on Nissan Almera Classic: a complete guide to selection and replacement

Nissan Almera Classic (also known as Nissan Sunny B10 or Almera G15 depending on market) is a reliable sedan, but even its braking system requires regular maintenance. The front pads here wear out faster than the rear ones due to greater load, especially in the urban cycle with frequent braking. If you hear a creaking noise, notice an increased braking distance, or the steering wheel wobbles when braking, it’s time to pay attention to the condition of the pads.

In this article we will look at which pads are suitable for Almera Classic, how to choose them correctly (original vs analogues), when exactly replacement is required and how to carry out the procedure yourself. We will also discuss common mistakes that shorten the life of the pads and give recommendations for running in new parts. If you drive aggressively or frequently carry heavy loads, the information will be especially useful - the braking system is pushed to its limit in such conditions.

Which front pads are suitable for Nissan Almera Classic?

On Almera Classic (body B10, engines 1.5L GA15DE And 1.6L GA16DE) pads with catalog numbers are installed, depending on the year of manufacture and configuration. Original parts from Nissan have an article number 40520-9M000 (or 40520-9M00A for later models). However, there are dozens of analogues on the market - from budget to premium, and the choice depends on driving style and budget.

Important: pads for Almera Classic with ABS and without her interchangeable, but if your car is equipped with a system EBD (electronic brake force distribution), it is better to choose parts marked "for EBD" — they have an optimized composition of friction material. Also pay attention to caliper size: on restyled models (after 2008), pads with different mounting holes can be installed.

• 🔧 Original: Nissan 40520-9M000 - the best choice in terms of price/quality ratio, but they are often counterfeited.
• 💰 Premium: Brembo P 24 026, ATE 13.0460-2839.2 - durable, little dust, but 2-3 times more expensive.
• ⚡ Budget: TRW GDB1446, Ferodo FDB425 — a good option for a quiet ride.
• ⚠️ Exotic: Akebono ACT907A (Japanese quality, but rarely found on sale).

Check when purchasing certificate of conformity - fakes often have softer friction material, which wears off quickly and leaves metal shavings on the discs. If you choose non-original pads, give preference to brands that supply parts to the assembly line Nissan (For example, Sumitomo or Advics).

Signs of front pad wear: when is it time to change?

The manufacturer recommends checking the condition of the pads every 15,000–20,000 km, but actual service life depends on driving style. For example, in a taxi or when driving along mountain serpentines, the pads can wear out within 10,000 km. Here are the key symptoms that should not be ignored:

• 🔊 Creaking or whistling when braking - a sign of thinning of the friction layer (many pads are equipped with indicator plates).
• 🚗 Increased braking distance - if the car brakes worse than usual, even with dry discs.
• 🌀 Vibration or wobble in the steering wheel - may indicate uneven pad wear or brake disc deformation.
• 💨 Black dust on rims - the norm for new pads, but if there is too much of it, this indicates low quality friction material.

Critical wear occurs when the thickness of the friction layer reaches 2–3 mm. You can check this visually through the caliper inspection window or by removing the wheel. On Almera Classic there is also electronic wear indicator (on some trim levels), which closes a contact on the dashboard when the condition of the pads is critical (the light comes on BRAKE).

⚠️ Attention: if you noticed metallic clang when braking, this means that the friction layer has completely worn out and the metal base of the pad scratches the brake disc. In this case, you will need not only replacing the pads, but also resurfacing or replacing the discs.

Symptom	Probable Cause	Action
Creaking noise when you lightly press the pedal	Worn indicator plate or sand ingress	Check the thickness of the pads, clean the caliper
Steering wheel vibration when braking	Uneven pad wear or disc deformation	Measure the thickness of the disc, check the caliper for wedging
Pulling the car to the side	Oily pads or caliper malfunction	Check the tightness of the cylinders, clean the pads
The brake pedal "falls"	Brake fluid leak or pad wear	Check fluid level, inspect pads and hoses

Step-by-step instructions for replacing front pads

Replacing the pads with Nissan Almera Classic does not require special tools, but will require care. If you have never worked on the brake system, it is better to contact a service center - mistakes here can cost your safety. To work you will need:

• 🔧 A set of sockets and keys (required) 12 mm, 14 mm, 17 mm).
• 🔨 Hammer and screwdriver (for removing guides).
• 🧴Brake fluid DOT-4 (in case of bleeding the system).
• 🧽 Brake cleaner (eg. Liqui Moly Bremsen-Reiniger).
• 🛠️ Lubricant for caliper guides (SLIPKOTE 220-R DBC).

Before starting work open the hood and remove the brake fluid reservoir cap - this will prevent excess pressure when pressing the caliper piston. Also lock the rear wheels (for example, stops) and engage first gear (or P on automatic transmission).

Prepare new pads and grease for the guides -->

Step 1: Removing the caliper

Unscrew the two bolts securing the caliper to the bracket (usually 14 mm And 17 mm). Carefully hang the caliper on a wire or a special hook - do not allow sagging on the brake hose, it may damage it. Remove the old pads and inspect the brake rotor for grooves or cracks.

Step 2. Installing new pads

Before installing new pads press the caliper piston back into the cylinder. To do this, you can use a clamp or an adjustable wrench. Place the new pads on the guides, making sure they are aligned tight and without distortion. If the pads have a wear indicator, it must be installed from the inside of the disk.

Step 3. Assembly and testing

Reinstall the caliper and tighten the bolts to torque. 25–30 Nm. Put the wheel on, lower the car and press the brake pedal several times until the pads rub against the discs. Check the brake fluid level and add if necessary.

⚠️ Attention: after replacing the pads For the first 200–300 km, avoid sudden braking — the friction material should rub against the disc. Also check for brake fluid leaks around the caliper within a week after replacement.

Common mistakes when replacing pads and how to avoid them

Even experienced car owners sometimes make mistakes that lead to premature pad wear or damage to the brake system. Here are the most common mistakes:

• 🛑 Unlubricated caliper guides — leads to jamming and uneven wear of the pads. Always apply high temperature grease on the guide pins.
• 🔄 Forgot to press in the caliper piston - without this, new, thicker pads simply will not fit into place. Use a clamp or special tool.
• 🧹 Dirt on the surface of the disc or pads — even small sand particles shorten the service life. Clean all parts brake cleaner, and not a regular solvent.
• 🔧 Overtightened caliper bolts - may deform the bracket. Use a torque wrench 25–30 Nm.

Another common mistake is installing pads without checking brake hoses. On Almera Classic Hoses crack over time, especially at the connection points with the caliper. If you notice microcracks or swelling, the hose needs to be replaced - otherwise it may burst under pressure, which will lead to complete loss of brakes.

Also, many people forget about running in new pads. In the first 100–200 km after replacement, avoid:

• ❌ Sudden braking at high speed.
• ❌ Holding the brake pedal for a long time (for example, on a descent).
• ❌ Aggressive driving with frequent acceleration/braking.

Comparison of original and non-original pads: what to choose?

The question is "original or analogue?" is eternal, and the answer depends on your priorities. Original pads Nissan are guaranteed to fit in size and composition, but their price is often inflated. Analogues may be cheaper, but not all of them are equally good. Let's compare the key parameters:

Parameter	Original pads	Premium analogues (Brembo, ATE)	Budget analogues (TRW, Ferodo)
Service life	30,000–40,000 km	35,000–50,000 km	20,000–30,000 km
Noise level	Low (silent)	Very low	Medium (may squeak)
Dusty	Moderate	Minimum	High
Price (set per axle)	2 500–3 500 ₽	3 000–5 000 ₽	1 200–2 000 ₽
Counterfeits on the market	Often	Rarely	Sometimes

If you drive mostly around the city and do not load the brakes, budget analogues (TRW or Ferodo) would be a good choice. For an aggressive driving style or frequent trips on the highway, it is better to take Brembo or ATE - they last longer and heat up less. Original pads are optimal if you value the balance of price and quality, but buy them only from authorized dealers.

Interesting fact: on Almera Classic pads are often installed from the factory Sumitomo (Japanese manufacturer, supplier for Nissan). They are sold under item number SC-538 and are not inferior in quality to the original, but cost 20–30% less.

How to extend the life of the front pads?

Even the most expensive pads will quickly wear out if you do not follow simple operating rules. Here's what will help increase their resource:

• 🚦 Smooth braking — Avoid sudden pressure on the pedal, especially at high speed. Use engine braking on the slopes.
• 🚿 Brake washing — in winter, after a trip on salty roads, wash the brake mechanisms with water (but not immediately after a hot trip!).
• 🔧 Regular caliper checks — once a year, lubricate the guides and check the piston boots.
• 🛞 Tire pressure monitoring — incorrect pressure increases the load on the brakes.

Also worth avoiding keeping your foot on the brake pedal for a long time in traffic jams - this leads to overheating of the pads and discs. If you often get stuck in traffic jams, use hand brake to secure the machine.

On Almera Classic with ABS it is important to monitor the condition wheel speed sensors. If the sensor is dirty or damaged, the system may not operate properly, causing uneven pad wear. Clean the sensors from dirt every 10,000 km.

What to do if the pads squeak after replacement?

The creaking of new pads in the first 100–200 km is normal (they rub against the disc). If the squeak does not go away:

1. Check to see if any lubricant has come into contact with the friction material.

2. Make sure the pads are installed correctly (wear indicator on the inside).

3. The pads may be of low quality - some budget brands add metal shavings to the composition, which squeaks.

4. As a last resort, use anti-squeak plates (For example, ATE 03.9902-0109.2).

FAQ: Frequently asked questions about front pads on Nissan Almera Classic

Is it possible to install pads on only one axle (for example, only the front ones)?

No, the pads are always changed pair on one axis (left + right). If you replace only one pad, the braking force will be distributed unevenly, which will cause the car to pull to the side when braking. The exception is if one pad is mechanically damaged (for example, a piece has broken off), but even in this case it is better to replace both.

How often should the pad thickness be checked?

Recommended interval - every 10,000–15,000 km or before long trips. On Almera Classic You can visually assess wear through the caliper inspection window (if there is one) or by removing the wheel. Also pay attention to wear indicator - a metal plate that begins to creak when the pads are in critical condition.

Which is better: ceramic or semi-metallic pads?

For Almera Classic optimal semi-metallic pads - they dissipate heat better and last longer in the urban cycle. Ceramic pads produce less dust and are quieter, but they perform worse at low temperatures (for example, in winter) and are more expensive. If you drive mostly around the city, choose semi-metallic (ATE or Brembo). For the route, you can consider ceramics (Akebono).

Do I need to change brake discs and pads?

Not always. Discs must be replaced if their thickness is less minimum acceptable (for Almera Classic this is usually 19–20 mm, the exact number is indicated on the disc itself). If the disc is smooth, without deep grooves or cracks, it can be left. However, if the pads are worn down to metal and the disc is scratched, you will need groove or replacement. Check the disc runout - if it exceeds 0.15 mm, the disk needs to be changed.

Is it possible to sharpen brake discs yourself?

Technically possible, but not recommended. Grooving requires a special machine and skills, otherwise the disc may turn out uneven, which will lead to vibrations during braking. On Almera Classic discs are inexpensive (from 1,500 ₽ per piece), so it’s easier to buy new ones. If you still want to sharpen, contact a specialized service - they use machines with diamond cutters, which ensure accuracy.
