Operation Nissan Almera Classic in Russian conditions, it requires close attention to the braking system, since it is the front wheels that take on the main load when stopping. Brake pads are consumables that inevitably wear out over time, and their condition directly affects driving safety. Ignoring signs of wear can lead to the destruction of brake discs, which will significantly increase the cost of subsequent repairs.
There are many opinions about what parts to install on this car, because factory recommendations often differ from the actual needs of drivers. You must understand that front brake pads on Nissan Almera Classic have their own design features that dictate the choice of specific analogues. Incorrect selection will lead to squeaks, reduced braking efficiency or premature wear of paired units.
Design features of the Almera Classic brake system
The front wheel brake system on this model is a disc type with a floating caliper. This means that when you press the brake pedal, the piston moves and presses the pad against the disc, while the caliper is pulled in the opposite direction, attracting the second pad. This design requires a perfect parallel fit, which is impossible without high-quality guides and correct friction linings.
It is important to consider that brake pad size strictly regulated by the manufacturer. Any deviations in geometry or thickness may result in the bracket not being able to operate correctly, causing the unit to overheat or the wheel to jam. This is especially critical for cars with high mileage, where wear on the guides may have already begun.
Many owners are faced with the fact that after replacing parts, extraneous sounds occur. This is often due to the fact that brake calipers require thorough cleaning and lubrication before installing new elements. Without proper preparation, even the most expensive pads will not work correctly.
Signs of need for replacement and diagnosis
Determine when to replace front brake pads, it is possible both visually and by indirect signs while driving. The most obvious signal is the appearance of a characteristic metallic grinding sound when you lightly press the pedal. This sound is usually produced by a wear indicator, which begins to rub against the disc when the friction layer thins to a critical point.
In addition to sounds, you should pay attention to the behavior of the car when braking. If Nissan Almera Classic starts to pull to the side, or the brake pedal becomes more “wobbly” and requires more travel, this is a sure sign of problems with the pads or caliper. In some cases, a beating may appear on the steering wheel, although more often it indicates deformation of the disc itself, which occurs due to overheating from worn linings.
Visual examination is the most reliable diagnostic method. By removing the wheel, you can assess the remaining thickness of the friction layer. If it is less than 2-3 mm, operation becomes dangerous. Also pay attention to the presence of oil stains on the surface of the pads, which indicates a fluid leak from the caliper.
Review of popular brands and selection of the original
The auto parts market offers a huge selection of options for Nissan Almera Classic, from cheap knockoffs to premium brands. Original pads from Nissan (code 31040-4M40A or 31040-AX601) are considered the standard of reliability, providing balanced braking and minimal disc wear. However, their cost often exceeds budget offers, and their service life may not be the highest.
Among the popular analogues, it is worth highlighting the brands Tokico, TRW and Textar. These manufacturers often act as suppliers to the assembly line and offer quality comparable to the original. They are great for quiet city driving, providing predictable car behavior.

Step-by-step instructions for replacing front pads
The process of replacing the front pads Nissan Almera Classic does not require complex equipment, but requires a jack, a set of keys and a pry bar. You need to start work by placing the car on a level surface and securing the rear wheels with wheel chocks. This will ensure your safety during work.
First you need to remove the wheel and unscrew the lower caliper guide bolt. After this, the upper part of the caliper can be moved up and secured with wire so as not to damage the brake hose. Next, the old pads are removed and the inner surface of the caliper is carefully inspected.
Before installing new elements, it is necessary to press the caliper piston into the body. This can be done with a special mandrel or clamp, using an old block to distribute the force. It is important to monitor the condition of the pistonso as not to damage its boot.
- 🔧 Clean the caliper guides from old grease and dirt with a metal brush.
- 🛢️ Apply special high-temperature grease to the guides and the back of the pads.
- ⚙️ Check the condition of the guide boots, replace them if necessary.
☑️ Preparing to replace pads
⚠️ Attention! Do not use regular lithium or graphite grease on the caliper guides. Use only special high-temperature brake lubricant (for example, silicone-based), otherwise the guides may seize when heated.
Install the new pads into the bracket, making sure they move freely. Before putting the caliper back on, check the brake fluid level in the reservoir. If it is too high, liquid may spill out due to the depressed piston.
What to do if the piston does not press in?
If the piston does not budge, check whether the brake fluid reservoir is open. Also make sure that the caliper is not warped and that the guides are not burred. Sometimes warming up the caliper with a hair dryer helps, but it is better to check the condition of the piston and boot.
The nuances of rolling in and running in new pads
After installing new parts brake pads require a rolling-in period so that the friction material fits tightly to the surface of the disc. During the first 300-500 kilometers, sharp braking and extreme loads should be avoided. Smooth pedal strokes ensure perfect contact.
Ignoring this step can lead to overheating and uneven wear of the linings. As a result, carbon spots will appear on the disc, which will cause the steering wheel to vibrate when braking. This phenomenon is often confused with disk deformation, although the problem lies precisely in improper operation immediately after replacement.
If you notice that the pedal is softer than usual, check for air in the system. Sometimes when replacing pads, some air can get into the circuit, especially if you disconnected the hoses or pressed the piston too hard. In this case, the brakes will need to be bled.
Keep receipts and packaging from new pads at least until the first maintenance. This will help prove their originality and quality in the event of a warranty dispute or the need to return.
Common maintenance mistakes
One of the most common mistakes is replacing only one pair of pads. All four wheels must be replaced to ensure uniform braking. If the front pads are new and the rear pads are old, the car may behave unpredictably during emergency braking, which is dangerous on slippery roads.
Another common problem is insufficient cleaning of the seats. If rust and dirt remain on the caliper, the new pads will not fit tightly, causing them to wear out quickly and cause squeaking noises. Cleaning the caliper must be thorough, using brake cleaner.
Also, owners often forget to check the condition of the brake discs. If the disc has deep grooves or runout, installing new pads will not give the desired effect. In such cases, it is necessary to replace discs and pads together to achieve optimal results.
⚠️ Attention! Never leave the caliper hanging from the brake hose without securing it. This can lead to damage to the inner braid of the hose and subsequent leakage of brake fluid, which is critically dangerous.

Frequently asked questions from owners
How long do front pads last on a Nissan Almera Classic?
Service life depends on driving style and quality of parts. On average, original pads last 30-40 thousand kilometers, while high-quality analogues can last up to 50 thousand. With aggressive driving, the resource can be reduced to 15-20 thousand kilometers.
Is it possible to change pads without replacing discs?
Yes, if the depth of the grooves on the discs does not exceed 1-2 mm, and the surface does not have deep burrs or cracks. However, when the pads wear down to the metal, the disc often has deep grooves, which requires regrooving or replacement.
Why do new pads squeak?
The creaking can be caused by poor quality lubrication of the guides, lack of lubrication on the back of the pad, or dust getting into the mechanism. This may also be a sign of poor quality friction material.
Do I need to grind the pads after replacing them?
Definitely. For the first 200-300 km, sharp braking should be avoided so that the friction layer is evenly distributed over the surface of the disk. This will prevent overheating and vibration.
Regular inspection and timely replacement front brake pads on Nissan Almera Classic is the key to your safety and saving money on repairing complex components. Do not delay diagnostics until a grinding noise appears, but carry out an inspection at every maintenance.
