Front brake pads for Nissan Almera G15: part numbers, selection and replacement

Brake system Nissan Almera G15 (2012–2019) requires special attention, and the front pads are one of the key consumables here. Their timely replacement not only guarantees safety, but also prevents expensive repairs of brake discs. However, selecting suitable pads often raises questions: which original part numbers are relevant for G15, which analogues are not inferior in quality, and how not to run into a fake?

In this article we will look at all front pad articles for Almera G15 - from factory ones to proven analogues, we will compare them by price and service life, and also give step-by-step instructions for replacement. We will pay special attention a common mistake when choosing pads for restyled versions (since 2015), where the parameters of the brake calipers have been changed. If you notice squeaking, vibration when braking, or increased braking distance, this information can save you time and money.

Original front pads for Nissan Almera G15: part numbers and features

Factory pads from Nissan provide the optimal combination of braking performance and wear resistance, but their price often forces owners to look for alternatives. For Almera G15 (including restyling 2015–2019) the following items are relevant:

• 🔧 40520-4M000 - original kit for versions until 2015 (1.6 l, 102 hp). Suitable for calipers Akebono.
• 🔧 40520-4M00A — updated version for restyled models (from 2015), compatible with calipers TRW.
• 🔧 40520-JM00A - a universal item for the markets of Asia and Europe, often found in dealer catalogs.

Important: original pads are supplied in boxes with a hologram Nissan and labeling Genuine Parts. Fakes often lack the logo of the caliper manufacturer (Akebono/TRW), and the pads themselves may have uneven edges or uneven coating of friction material.

⚠️ Attention: Pads with article number 40520-4M000 physically will not fit on restyled ones Almera G15 (2015+) due to modified caliper geometry. Installing incompatible parts will result in uneven disc wear and vibration when braking.

Average resource of original pads - 30–50 thousand km, but it greatly depends on the driving style and the quality of the brake fluid. When driving aggressively or using cheap analogue fluids, the friction material can “glass”, which leads to squeaking and reduced braking efficiency.

The best analogues of front pads: comparison of manufacturers

Alternative pads for Almera G15 can be no worse than the original if you choose a trusted manufacturer. Below is a comparison table of popular brands indicating article numbers, compatibility and features.

Manufacturer	Article	Compatibility	Features	Average price, ₽
Akebono	ACT907A	All G15 versions	Soft friction material, minimal disc wear	2 800–3 500
Brembo	P 24 063	Until 2015	High temperature resistance, suitable for sporty riding style	3 200–4 000
TRW	GDB1446	Restyling (2015+)	Optimal price/quality ratio, low noise level	2 500–3 100
Ferodo	FDB1446	All versions	Budget option, but prone to squeaking during cold braking	1 800–2 300
Textar	2463901	Until 2015	Moderate wear, suitable for urban use	2 200–2 800

When choosing analogues, pay attention to ECE R90 certification — it guarantees compliance with European safety standards. Pads without a certificate may have an unstable coefficient of friction, which leads to an increase in braking distance by 10–15%.

Among the owners Almera G15 are especially popular Akebono ACT907A — they make virtually no noise and are gentle on the disks. However, for aggressive driving they are better suited Brembo P 24 063, despite their higher price.

Signs of Front Pad Wear: When to Replace

The manufacturer recommends checking the condition of the pads every 15 thousand km, but their actual service life depends on many factors. The following symptoms indicate that it is time for replacement:

• 🚨 Creaking or whistling when braking - indicates wear of the friction material to the metal base. On the blocks Nissan Almera G15 the squeak usually triggers when there is residual thickness 2–3 mm.
• 🚨 Vibration on the steering wheel or brake pedal - may indicate uneven wear of the pads or deformation of the brake discs.
• 🚨 Increased braking distance — if the car brakes worse than usual, this is a sign of “oiling” of the pads or their critical wear.
• 🚨 Metal clang - means that the friction material has completely worn off and the metal base of the pad is in contact with the disc. In this case, urgent replacement is required, otherwise the discs will have to be sharpened or replaced.

On Almera G15 there is also a problem "seizing" of pads due to corrosion of the caliper guides. This manifests itself as jamming of the brakes after parking or uneven wear of the pads (one wears out faster than the other). The solution is to clean and lubricate the guides with a special paste (for example, TRW PFG110).

⚠️ Attention: If, after replacing the pads, the brake pedal becomes “soft” or falls down, this is a sign air entering the system. It is necessary to pump the brakes - otherwise braking efficiency will decrease by 30–40%.

To accurately diagnose pad wear, a visual inspection through the wheel spokes (with the steering wheel turned) or measuring the thickness of the friction material is sufficient. Minimum permissible thickness for Almera G15 — 2 mm. If the material is thinner, the pads must be replaced.

How to check the pads without removing the wheel?

Through the hole in the caliper (if there is one) or using a mirror and a flashlight. On some versions of the G15, there is an inspection window in the brake disc - through it the edge of the pad is visible. You can also focus on the wear indicator (metal tongue), which begins to creak when worn critically.

Step-by-step instructions for replacing front pads

Replacing the pads with Nissan Almera G15 does not require special tools and can be done independently in 1–1.5 hours. You will need:

• 🔧 Jack and stops (or lift)
• 🔧 Key on 14 mm for caliper guides
• 🔧 Socket wrench on 17 mm for caliper bolt
• 🔧 Flat blade screwdriver (for pressing in the piston)
• 🔧 Lubricant for guides (for example, Slipkote 220-R DBC)
• 🔧 New pads and, if necessary, brake fluid DOT-4

Before starting work, make sure that the machine is on a level surface and that the handbrake is released. Also check the level of brake fluid in the reservoir - if it is maximum, some of the fluid must be pumped out before pressing the caliper piston (otherwise it will overflow).

Disconnect the negative terminal of the battery (for safety)|Loosen the wheel bolts|Raise the car with a jack and install jack stands|Remove the wheel and clean the caliper from dirt|Prepare new pads and tools-->

Step by step process:

1. Remove the wheel and clean the caliper from dirt with a wire brush. Pay attention to the guide boots - if they are torn, they need to be replaced.

2. Unscrew the lower caliper mounting bolt (key on 17 mm) and fold the caliper up. Do not disconnect the brake hose!

3. Remove the old pads. If they are stuck, carefully pry them off with a screwdriver. Clean the seats from rust and dirt.

4. Push the caliper piston back into the cylinder. To do this, use a screwdriver or a special tool. On restyled versions (2015+), the piston is screwed in clockwise.

5. Install new pads, first applying a thin layer anti-seize paste on the back side (not on the friction material!).

6. Lubricate the caliper guides and reassemble everything in reverse order. After installing the wheel, press the brake pedal several times until the piston comes close to the pads.

After replacing the pads on both sides, be sure to check:

• 🔹 No brake fluid leaks
• 🔹 Uniform fit of the pads to the disc (rotate the wheel manually)
• 🔹 Brake operation while driving (avoid sudden braking for the first 100–200 km to break in)

Common mistakes when replacing pads and how to avoid them

Even experienced car owners sometimes make mistakes that shorten the life of the pads or lead to breakdowns. Here are the most common of them:

• ❌ Ignoring guide lubrication — leads to caliper wedging and uneven pad wear. Use only high temperature grease (ordinary lithol or graphite will not work).
• ❌ Installing pads without cleaning the seats — rust and dirt interfere with a tight fit, which is why the pads can “dangle” and squeak.
• ❌ Forgetting to recess the caliper piston - without this, new, thicker pads simply will not fit into place. On the restyled G15, the piston must not only be pressed in, but screw in.
• ❌ Using cheap pads without a certificate - they may have an uneven density of the friction material, which leads to vibrations during braking.
• ❌ Don't check brake fluid — if it is old (more than 2 years), it needs to be replaced, otherwise moisture in the system will lead to corrosion of the calipers.

Another typical problem is improper running in of pads. In the first 200–300 km after replacement, avoid sharp braking so that the friction material is evenly distributed over the disc. If you ignore this rule, the pads may “glaze over” and their efficiency will decrease by 20–30%.

On Almera G15 with ABS it sometimes works after replacing the pads brake system fault indicator on the dashboard. This is due to the pad wear sensor (if installed). To reset the error, just press the brake pedal sharply several times with the ignition off, and then start the car.

Comparison of pads for pre-restyle and restyle Almera G15

In 2015 Nissan Almera G15 underwent restyling, during which some parts of the brake system changed. Main differences:

Parameter	Until 2015	Since 2015 (restyling)
Caliper manufacturer	Akebono	TRW
Article number of original pads	40520-4M000	40520-4M00A
Pad mounting type	Latches	Spring clips
Brake disc diameter	262 mm	262 mm (but hub geometry changed)
Compatibility with analogues	Brembo P 24 063, Textar 2463901	TRW GDB1446, Akebono ACT907A

The main problem when selecting pads for restyled versions is mounting incompatibility. For example, dorestayl pads will not fit into the caliper TRW due to the different shape of the spring brackets. Therefore, when purchasing, always check the year of manufacture of the car.

If you are not sure about the version of your Almera G15, check:

• 📅 Year of manufacture (before 2015 or after)
• 🔧 Marking on the caliper (Akebono or TRW)
• 📏 Pad attachment form (latches or staples)

Recommendations for caring for the Almera G15 brake system

To help your pads and discs last longer, follow these tips:

• 🔹 Check the brake fluid every 2 years - it is hygroscopic and accumulates moisture over time, which leads to corrosion of the calipers.
• 🔹 Avoid holding the brake pedal for long periods of time at traffic lights - this overheats the pads and discs.
• 🔹 Wash your brakes when replacing wheels or every 10 thousand km, dirt and salt accelerate wear.
• 🔹 Use quality lubricant for guides (for example, Molykote G-3407). Conventional grease burns out at high temperatures.
• 🔹 Control your driving style — sharp braking reduces the life of the pads by 2–3 times.

On Almera G15 it is also recommended to check it once every 60 thousand km condition of brake hoses. Over time, they lose elasticity, which can lead to rupture under pressure. Signs of hose wear:

• Cracks on the surface
• Blistering or wet spots (fluid leakage)
• Hard to the touch (a fresh hose should be soft)

⚠️ Attention: If after washing or rain the brakes begin to work worse, this is a sign moisture getting on the pads. To restore efficiency, brake hard several times on a dry road - this will warm up the pads and remove moisture.

Don't forget about rear brake pads - their resource for Almera G15 is about 60–80 thousand km. When replacing the front pads, always check the condition of the rear ones, even if they do not squeak yet.

FAQ: Frequently asked questions about front pads Nissan Almera G15

Is it possible to install Renault Logan pads on Almera G15?

No, despite the common platform, the calipers and pads of these models are different. On Logan pads with article number are used 40520-550Rwhich are not suitable for Almera G15 neither in size nor in fastening.

How often do you need to change brake fluid on Almera G15?

The manufacturer recommends replacement every 2 years or 40 thousand km. Brake fluid is hygroscopic and accumulates moisture over time, which lowers the boiling point and leads to corrosion of the calipers. Liquid suitable for G15 DOT-4 (For example, Motul DOT 4 Racing or Castrol React DOT 4 Low Temp).

Why does the car pull to the side when braking after replacing the pads?

This may be caused by:

• Uneven tightening of caliper guides
• Contamination or corrosion of pad seats
• Malfunction of the brake cylinder (piston does not return to its original position)
• Different degrees of wear on the brake discs on the left and right wheels

Solution: check the free play of the calipers, clean the seats and sharpen the discs if necessary.

Which pads squeak the least on Almera G15?

The lowest noise level is shown by:

• Akebono ACT907A - due to soft friction material
• TRW GDB1446 - have special anti-squeak plates
• Textar 2463901 — optimal for city driving

The squeak also depends on the condition of the brake discs. If they have beads or uneven wear, even the best quality pads can become noisy.

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

Bleeding is required only if:

• Have you disconnected the brake hose from the caliper?
• There is air in the system (the brake pedal has become “soft”)
• The brake fluid level has dropped below the minimum level

If you just removed the caliper and replaced the pads, bleeding is not necessary. But check the fluid level in the reservoir and add if necessary.
