Replacing front brake pads on a Nissan Almera G15: a detailed guide with nuances

Replacing front brake pads with Nissan Almera G15 - a procedure that every owner of this car faces sooner or later. Unlike more complex repair work, this operation can be performed independently, saving on the services of a service station. However, there are some nuances here: from choosing the right pads to correct installation and subsequent bleeding of the brakes.

In this article, we will walk you through the entire process step by step, from preparing the tools to the final check. We will pay special attention to typical mistakes that beginners make and give recommendations on choosing consumables. If you've never worked on the brake system, don't worry: the instructions are adapted for beginners, but taking into account technical details that are important for experienced car owners.

When do you need to change the front pads on Almera G15?

The manufacturer recommends checking the condition of the brake pads every 15–20 thousand km, but their actual service life depends on driving style and operating conditions. For example, during aggressive braking in the urban cycle, the pads can wear out within 10–12 thousand km, whereas with quiet driving on the highway they will last up to 30–40 thousand.

The need for replacement can be determined by the following signs:

• 🔊 Creaking or whistling when braking, this is a wear indicator built into the pads. On Almera G15 it is triggered when the thickness of the friction layer reaches 2–3 mm.
• 🚗 Increased braking distance or a “soft” pedal - indicates critical wear or uneven wear of the pads.
• 🔧 Visual inspection: if you can see through the wheel spokes that the thickness of the pad is less than 5 mm, it’s time to change it.
• 💡 Brake light is on on the dashboard (on some versions Almera G15 with ABS).

Important: if you notice deep grooves on the brake disc or uneven pad wear (one wears out faster than the other), this may indicate problems with the caliper or guides. In this case, diagnostics will be required.

⚠️ Attention! If you feel the steering wheel wobble or vibrate when braking, this may be a sign of a warped brake rotor. In this case, the pads are replaced in pairs, and the disc is ground or replaced.

Which pads to choose for Nissan Almera G15?

There are many brands on the market, but not all pads are equally suitable for Almera G15. Main selection criteria:

• 🔹 Friction material composition: semi-metallic pads are cheaper, but wear out the discs faster; ceramic ones are more expensive, but quieter and more durable.
• 🔹 Manufacturer: original pads Nissan (article 40520-4M000) or analogues from Brembo, TRW, Ferodo, ATE.
• 🔹 Presence of wear sensor: on Almera G15 with ABS it is better to install pads with an indicator (if the old ones had one).

The table below compares popular models of pads for Nissan Almera G15 (2012–2019):

Brand	Article	Type	Average price (per set)	Features
Nissan (original)	40520-4M000	Semi-metallic	2 500–3 000 ₽	Optimal price/quality balance, minimal disc wear
Brembo	P 24 063	Low metal	2 200–2 700 ₽	Good braking at high temperatures, suitable for aggressive driving
TRW	GDB1446	Ceramic	3 000–3 500 ₽	Minimal noise, long service life, but high price
Ferodo	FDB1446	Semi-metallic	1 800–2 300 ₽	Budget option, but can creak at low temperatures

Advice: if you drive mainly around the city, choose ceramic pads — they generate less dust and are quieter. Better suited for the track or sporty driving style semi-metallic from Brembo or ATE.

Tools and materials for replacement

To change the pads yourself, you will need:

• 🔧 Jack And supports (or lift).
• 🔧 Balloon wrench for removing wheels.
• 🔧 Socket heads by 14 mm and 17 mm (for caliper guides).
• 🔧 7 mm hexagon (for some caliper models).
• 🔧 Hammer And screwdriver (to expand the caliper piston).
• 🔧 Brake fluid (DOT-4) - may be needed for pumping.
• 🔧 Guide lubricant (For example, Slipkote 220-R DBC).
• 🔧 Metal brush And brake cleaner (For example, LIQUI MOLY Bremsen-Reiniger).

Also prepare:

• 🧤 Gloves (brake dust is harmful to the skin).
• 👓 Protective glasses (when cleaning the caliper).
• 📸 Phone for filming the process (useful if something goes wrong).

⚠️ Attention! Never use to lubricate caliper guides. Litol, grease or WD-40. These compounds cannot withstand high temperatures and can cause the caliper to jam. Use only specialized lubricants!

Step-by-step instructions for replacing pads

Before starting work, make sure that the vehicle is on a level surface and that the handbrake is released (otherwise you won’t be able to press the caliper piston in). Also check the level of brake fluid in the reservoir - if it is maximum, before replacing the pads, pump out some fluid with a syringe, otherwise when the piston is pressed in, it will overflow.

Step 1: Removing the wheel and accessing the caliper

1. Loosen the wheel bolts (do not remove completely!).
2. Raise the car with a jack and install a support.
3. Remove the wheel and clean the caliper from dirt with a brush and cleaner.

Step 2. Removing the caliper

1. Unscrew the two bolts securing the caliper to the bracket (usually 14 mm or 17 mm).
2. Carefully remove the caliper and hang it on a wire or rope to avoid damaging the brake hose.
3. Remove the old pads and inspect the brake rotor for grooves or cracks.

Step 3. Installing new pads

1. Clean the pad seats from rust and dirt.
2. Apply a thin layer of lubricant to caliper guides And back side of the pads (where they contact the bracket).
3. Install the new pads, making sure they are level and not warped.

Step 4. Returning the caliper to its place

1. Before installing the caliper, you must press the piston back into the cylinder. To do this, use a special tool or carefully pry the piston with a screwdriver while pressing on it. On some models Almera G15 The piston is screwed in (you will need to turn it counterclockwise).
2. Reinstall the caliper and tighten the bolts to torque. 25–30 Nm.

Step 5. Check and bleed the brakes

1. Install the wheel and lower the car.
2. Press the brake pedal several times until the pads are in place.
3. Check the brake fluid level and add if necessary.
4. Test the brakes at low speed, making sure there is no squeaking or squealing.

What should I do if the caliper piston does not press in?

If the piston does not move, there may be pressure remaining in the system. Try unscrewing the brake fluid reservoir cap and try again. If this does not help, the caliper may be jammed and require repair or replacement.

Typical mistakes when replacing pads on Almera G15

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

• 🔧 Incorrect pad installation (left and right or top and bottom are confused). On Almera G15 The pads may have an asymmetrical shape - be sure to check the marks.
• 🔧 Lack of lubrication on the guides — leads to caliper jamming and uneven wear.
• 🔧 Ignoring the condition of the brake discs. If the disc has deep grooves (more than 1 mm), it needs to be sharpened or replaced.
• 🔧 Unbleeded brakes after replacement. If the pedal remains soft, air may have entered the system.
• 🔧 Using incompatible pads (for example, from Renault Logan, which are similar in appearance, but have a different composition of friction material).

Another common problem is new pads squeak. It may occur due to:

• 🔊 Poor quality friction material (especially cheap analogues).
• 🔊 Lack of anti-squeak plates (if they were on the old pads, they need to be transferred to the new ones).
• 🔊 Dirt gets between the pad and the brake disc.

If the squeaking does not go away after 200–300 km, try applying it to the back of the pads. anti-squeak paste (For example, LIQUI MOLY Bremsen-Anti-Quietsch-Paste).

How to extend the life of brake pads?

The service life of the pads is Nissan Almera G15 depends not only on their quality, but also on driving style. Here are some tips to help you save on consumables:

• 🚦 Avoid hard braking - Brake smoothly, slowing down in advance.
• 🚗 Use engine braking on slopes or before traffic lights.
• 🔧 Clean the caliper and guides regularly from dirt and rust (every 10,000 km).
• 🔧 Check the brake fluid level - its low level or contamination accelerates the wear of the pads.
• 🚿 Wash wheels and brakes from salt in winter - this prevents corrosion of the guides.

Also note condition of brake discs. If they have a wavy surface or deep scratches, the pads will wear out 2-3 times faster. In this case, the discs need to be sharpened or replaced.

Interesting fact: on Almera G15 With automatic transmission, the pads wear out faster than on versions with manual transmission. This is due to the fact that the automatic engine brakes more often, and drivers with automatic transmissions use the brake pedal more often.

When is it necessary to replace brake discs?

Brake discs on Nissan Almera G15 designed for 80–120 thousand km, but their life depends on the quality of the pads and driving style. Disks need to be replaced if:

• 📏 Their thickness has become smaller 19 mm (nominal for front discs is 22 mm).
• 🔍 Deep furrows (more than 1 mm) or cracks appeared on the surface.
• 🌀 The disc has uneven wear (waviness), which is why you feel the steering wheel beating when braking.
• 🔥 The disc overheats (turns blue from high temperature) - this is a sign of a caliper malfunction or the use of low-quality pads.

When replacing disks, be sure to:

• 🔧 Change them a couple (both front or both back), even if one looks fine.
• 🔧 Use new mounting bolts (they come with the discs).
• 🔧 Bleed the brakes after replacement.

The cost of original disks for Almera G15 - about 5,000–7,000 RUR per piece. Analogues from Brembo or ATE will cost 3,000–4,500 rubles.

⚠️ Attention! If you notice that after replacing the pads the braking distance has increased and the pedal has become “wobbly”, this may be a sign airing the system. In this case, bleeding of the brakes is required.

FAQ: Frequently asked questions about replacing pads on Almera G15

Is it possible to change the pads on only one wheel?

No, the pads are always changed pair on one axis (both front or both rear wheels). If you replace the pads on only one side, this will lead to uneven braking and the car pulling to the side.

How long does it take to replace pads?

If you have the tools and experience, the work takes 1–1.5 hours on both wheels. Beginners may need up to 2-3 hours, especially if they have difficulty pressing the caliper piston.

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

If you just changed the pads and did not open the brake system (did not disconnect the hoses, did not change the caliper), bleeding is not required. However, if the caliper piston is difficult to press in or brake fluid is leaking from the reservoir, it is better to check the system for air.

Is it possible to use Renault pads for Almera G15?

Nissan Almera G15 built on a platform Renault-Nissan B0, so some parts are compatible. For example, pads from Renault Logan (article 40520-4M000) are suitable, but may differ in the composition of the friction material. It is better to use original pads or certified analogues for Almera.

What to do if a squeaking noise appears after replacing the pads?

Creaking can be caused by several reasons:

• 🔹 The pads haven’t gotten used to it yet (usually it goes away after 200-300 km).
• 🔹 There are no anti-squeak plates (if they were on the old pads).
• 🔹 Low quality friction material (especially cheap analogues).

Try applying a special paste to the back of the pads or replacing the pads with better ones.
