Operation Nissan Almera generation G15 in Russian road conditions requires special attention to the braking system. This car, often used in taxis or for daily trips around the city, subjects the brake mechanism to enormous loads. Wear front brake pads happens faster than many competitors due to the specifics of the suspension and the weight of the car. Ignoring signs of wear can lead to brake rotor failure and costly repairs.
Timely diagnostics and competent selection of spare parts are the key to your safety on the road. Owners Nissan Almera Often faced with a dilemma: buy original parts or stick with high-quality analogues. Understanding the technical nuances, part numbers and installation features will help you save money without losing reliability. Let us consider in detail all aspects of brake system maintenance.
Signs of wear and diagnostics of brakes
The first signal about the need to replace consumables is a characteristic sound. A grinding, squealing or metallic grinding sound when you press the brake pedal indicates that the friction layer has completely worn out. On some models Nissan Almera G15 has a wear indicator that physically touches the disc when it is critically worn, making a sound. However, relying on sound alone is dangerous, since in sound-insulated vehicles it may not be immediately audible.
A visual inspection requires removing the wheel, but it gives the most accurate picture. Pay attention to the thickness of the friction lining. If it is less than 2-3 millimeters, replace brake pads required. Also check the condition of the brake disc: the presence of deep grooves, scuffing or wobbling of the steering wheel when braking indicates that the disc also requires re-grooving or replacement.
Don't forget about the car's behavior on the road.
If the brake pedal has become “wobbly” or the car pulls to the side during heavy braking, this is a reason for urgent diagnostics of the entire system, including calipers and guides.
- The appearance of metal shavings in brake dust on wheel rims.
- Vibration of the steering wheel or body when pressing the brake pedal.
- Increased braking distance compared to usual indicators.
Original parts and high-quality analogues
Original pads for Nissan Almera G15 have an article number D1100-1AA1A (front axle). They provide the perfect balance between braking force, noise and wear. However, the original is often expensive, and there are many fakes on the market masquerading as dealer spare parts. Therefore, many car owners pay attention to certified analogues that are not inferior to the original in quality.
Choosing a brand is a compromise between price and resource. European and Japanese manufacturers specializing in friction materials are excellent for city driving. It is important to look at the production date, since the rubber components in the pads can become tanned over time, even on a store shelf.
The following table will help you compare popular spare parts options.
| Brand | Article | Features | Average resource |
|---|---|---|---|
| Nissan (Original) | D1100-1AA1A | Perfect compatibility, high price | 30-40 thousand km |
| TRW | GDB1316 | Excellent braking, soft material | 25-35 thousand km |
| Brembo | P 42.008 | High efficiency, harder to drive | 20-30 thousand km |
| Mapco | 14102 | Budget option, acceptable quality | 15-25 thousand km |
⚠️ Attention: Never save on brakes by buying unknown Chinese brands without reviews. Cheap pads often “melt” when overheated, losing efficiency at a critical moment.
When choosing an analogue, pay attention to the presence of a metal layer on the reverse side (anti-squeak shim), which dampens vibrations and reduces noise.
Some manufacturers offer pads with a ceramic composition, which generate less dust, but are much more expensive.

Preparation for replacement and necessary tools
Before starting work, it is necessary to prepare the workplace and tools. The car must be parked on a level surface, and wheel chocks must be placed under the rear wheels. You need to lift the car using a jack and be sure to fix it on safety stand (“goat”), since working under the machine without support is deadly.
You will need a standard set of tools: 12, 14, 17 wrenches, hex keys (usually 5 or 6), a flathead screwdriver and a torque wrench. Also, don’t forget to buy brake fluid to top up the reservoir and brake cleaner. It is necessary to clean not only the discs, but also the seats on the caliper.
- Set of sockets and ratchets.
- Caliper for squeezing the piston (or vice).
- Caliper guide lubricant (high temperature).
- Brake fluid DOT-4 or DOT-5.1.
☑️ Tools for replacing pads
Step-by-step replacement instructions
First, remove the wheel and unscrew the lower caliper guide bolt. It usually has a wrench size of 14 or 17, depending on the year of manufacture. The top bolt remains bolted, allowing the caliper body to be hinged upwards. Be careful not to damage the brake hose when lifting the caliper.
Take out the old pads. Pay attention to their position: the outer and inner pads may differ in the presence of a wear sensor or spring clips. Install the new pads in place, having previously lubricated the guide brackets with a special high-temperature grease. This is critical to avoid jamming.
The caliper piston must be pressed in as far as it will go.
This can be done using a special tool or a powerful vice, using the old block as a spacer.
⚠️ Attention: Before pressing the piston, be sure to check the brake fluid level in the reservoir. If it's full, liquid can spill onto the hood and ruin the paint or plastic.
What to do if the piston does not press in?
If the piston is stuck, do not use excessive force. Remove the caliper completely, check the integrity of the boot and try to gently rotate the piston while pressing in if it is a sliding caliper with threads. Otherwise, the caliper will need to be replaced.
Nuances of operation and common mistakes
One of the most common mistakes is incorrectly breaking in new pads. Immediately after replacement, you should not brake sharply or make emergency stops. It is necessary to perform a series of smooth braking at low speed so that the friction layer evenly adheres to the disc. This process is called “grinding in” and takes the first 200-300 kilometers.
It is also important to check the condition of the caliper guide boots. If they are torn, dirt and moisture can get inside, leading to corrosion and jamming. In such cases, replacing the pads alone will not solve the problem, and the caliper will have to be repaired or replaced. Inspect the system regularly, especially after off-road driving or in rainy weather.
Do not use brake cleaner to degrease rubber parts as this may cause them to deteriorate.
Use only special silicone lubricants for rubber seals.
If you are changing pads on only one axle, make sure they are from the same manufacturer and batch. Different friction compounds can cause uneven braking and skidding of the car.
Diagnostics and maintenance of calipers
Calipers on Nissan Almera The G15s are simple in design but require attention. When replacing pads, be sure to check whether the caliper moves freely on the guides. If it moves tightly, it can cause the pad to constantly rub against the disc, causing overheating and rapid wear.
Use a quality guide lubricant. Cheap graphite or copper based lubricants can wash off or thicken in the cold. Specialized synthetic lubricants (for example, from TRW, ATE, Slipkote) are designed for temperatures up to 1200°C and do not lose properties over a wide temperature range.
- Check that there is no play in the guide pins.
- Inspect the anthers for cracks and tears.
- Checking the cleanliness of the caliper seats.
Regular lubrication of caliper guides extends the life of not only the pads, but also the calipers themselves, preventing costly repairs.
Questions and answers (FAQ)
How often do you need to change the front pads on a Nissan Almera G15?
Service life depends on driving style and operating conditions. On average, replacement is required every 25-35 thousand kilometers. In an urban cycle with frequent traffic jams, the resource can be reduced to 20 thousand.
Is it possible to change the pads without removing the caliper?
No, for a quality replacement you need to remove the caliper or at least fold it back on its hinges to get to the guides and clean the seats from dirt and corrosion.
What to do if a new pad squeaks?
The creaking can be caused by lack of running-in, poor lubrication of the guides, or dirt getting between the pad and the caliper. Check the presence of anti-squeak plates and apply lubricant to the back of the pad.
Do I need to change the brake disc along with the pads?
If the disc thickness is minimal, there are deep grooves or runout, the disc needs to be replaced or sharpened. If the disc is in perfect condition, replacing the pads is enough.
Which brake fluid is best for Almera G15?
It is recommended to use DOT-4 or DOT-5.1 fluid. It should be changed every 2 years, as it is hygroscopic and loses its properties over time.
