The braking system is a critical safety element of any vehicle, and Nissan Almera Classic is no exception. This popular sedan, built on the B10 platform, is often used in taxis and as a first car, which places high stress on the chassis. That is why the condition of the front brake mechanisms requires constant attention from the owner.
Many car owners are faced with the need to replace consumables, but do not always understand how to select the right spare parts and perform installation without errors. Wrong choice front pads can lead to squeaking, uneven disc wear, or even loss of braking performance in an emergency. In this article we will examine in detail all aspects of brake system maintenance.
Design features of the brake system Nissan Almera Classic
Structurally, the front brake mechanism Nissan Almera Classic is a classic disk system with a floating bracket. This solution is time-tested and provides a good balance between maintenance costs and operational efficiency. The main elements are the brake disc, caliper, guides and friction linings themselves.
A special feature of this model is the use of calipers from the first generation Renault Logan, which makes them very common and easy to repair. However, owners should remember the specifics of fastening the guides and the specific requirements for lubrication of contacts. Ignoring these nuances often leads to caliper jamming or rapid wear. brake discs.
It is important to consider that depending on the year of manufacture and configuration, the dimensions of the parts may vary slightly. The standard diameter of the brake disc is 260 mm, but when replacing, always check the markings on the old element. It is also worth paying attention to the condition of the anthers and protective caps, since their damage leads to dirt getting inside the mechanism.
Signs of wear and diagnostics of brake condition
You can determine the need to replace the front pads both visually and by indirect signs in the car’s behavior. The most obvious signal is the appearance of a metallic grinding or squeaking sound when you press the brake pedal. This sound occurs because the friction material has worn out and the metal base has begun to contact the disc.
In addition to sound signals, you should pay attention to the beating of the brake pedal or steering wheel when decelerating. This may indicate not only wear on the linings, but also deformation of the brake disc. If you feel that the car is pulling to the side when braking, this is a sure sign that one of the calipers is stuck or the pads are worn unevenly.
Visual inspection through the wheel rims allows you to assess the thickness of the friction layer. If it is less than 2-3 mm, then operation becomes dangerous. For an accurate diagnosis, it is recommended to remove the wheel and inspect it. brake caliper entirely, checking the absence of brake fluid leaks and the integrity of the guide boots.
Review of manufacturers and selection of quality spare parts
The auto parts market offers a huge selection of options: from original parts to budget analogues. Original pads for Nissan Almera Classic (article D1100-89999 or D1100-59999) are of high quality, but their prices are often overpriced, and fakes are quite common. Many owners switch to proven analogue brands.
Among the popular manufacturers it is worth highlighting TRW, Brembo and Textar. These brands offer excellent value for money, delivering consistent, squeal-free braking. More budget options such as Brake Engine or Kashiyama, also have the right to life, but require more careful quality control during installation and can be noisier.
When choosing, be sure to check the packaging and the presence of holograms, as the market is overflowing with counterfeits. Good pads have clear markings, smooth friction material edges, and quality spring clips. You should not chase the lowest price, since cheap linings often contain asbestos that is harmful to health or have an unstable coefficient of friction.
- 🛑 Original spare parts: maximum reliability, but high price and risk of counterfeit.
- ✅ Brand analogues (TRW, Brembo): optimal balance of cost and resource.
- ⚠️ Budget options: acceptable for a quiet ride, but require frequent checking.

Required tools and materials for replacement
The process of replacing front pads does not require complex, specialized equipment, but having the right set of tools will make the task much easier. You will definitely need a jack and reliable stands (goats), since working under the car on one jack is strictly prohibited. Also prepare a set of wrenches and sockets, including a 14mm and 17mm wrench.
For quality maintenance, special lubricants for the guide supports and contact pads will also be required. Use only high temperature silicone or copper lubricants designed for brake systems. Regular machine oil or lithol are unacceptable, as they destroy rubber elements and lose their properties when heated.
Don't forget about the caliper piston pressing tool. You can use a special puller or vice, but this must be done carefully so as not to damage the rubber piston seal. A brush for cleaning the seats and penetrating lubricant (WD-40) for loosening stuck bolts are also useful.
☑️Collecting tools and materials
Step-by-step instructions for replacing front pads
The first step is to remove the wheel. Loosen the mounting bolts with the car standing, jack up the car, install a stand and remove the wheel. You can now access the caliper. Inspect its condition, check the brake fluid level in the reservoir - before starting work, the piston will need to be pressed in, which will force the fluid back out.
Unscrew the two caliper guide bolts, which are usually located on the inside. Be careful: the bolts may be soured, so treat them with penetrating lubricant in advance and let them sit. Remove the caliper bracket and hang it on a wire to the suspension spring so as not to damage the brake hose. Old pads are easily removed from the bracket.
Clean the seats in the bracket from dirt and rust with a brush. Install new pads, having previously lubricated their contacts with metal brackets and guides with special paste. Press the caliper piston into the cylinder until it stops. Reinstall the bracket and tighten the guide bolts to the recommended torque.
⚠️ Attention: Before installing the pads, be sure to check the condition of the caliper guide boots. If they are torn, dirt and moisture will get inside, which will cause the mechanism to jam after a couple of thousand kilometers.
After installing all the elements on the wheel, do not rush to lower the car. Press the brake pedal several times until it becomes firm. This is necessary so that the caliper pistons come out and press the pads against the discs. If you don’t do this, the first time you will simply drive with an empty brake pedal, which is extremely dangerous.
What to do if the piston does not press in?
Sometimes the piston jams due to corrosion or misalignment of the cuff. Do not use excessive force to avoid breaking the tool or piston. Try to slightly rock the piston when pressing or use a special puller. If the problem is not solved, the caliper may need to be completely replaced or repaired (change the cuff).
Typical mistakes and tips for extending service life
One of the most common mistakes is ignoring the replacement of guide supports. Over time, the lubricant in them dries out and the bracket stops moving, which leads to uneven wear on the pads on one side. Regularly check the mobility of the bracket and, if necessary, change the guide repair kits.
Also, many car owners forget about the need to grind in new pads. Immediately after the replacement, you should not make sudden emergency braking. Allow the friction material to adapt to the disc during the first 200-300 kilometers. This will ensure maximum contact area and extend the life of both pads and discs.
Pay attention to the cleanliness of the brake system. The accumulation of dirt and brake dust on the guides can cause jamming. It is recommended to clean and lubricate every time the pads are replaced. This is a small investment of time that will save you money on costly caliper repairs in the future.
When purchasing new pads, be sure to check them for metallic noise (squeaking). If the pad has a slot or groove to remove dust and gases, this is a good sign - such pads overheat less and squeak less.

How often do you need to change the front pads on a Nissan Almera Classic?
The service life of the front pads depends on the driving style and operating conditions. On average they travel from 25,000 to 40,000 km. In city mode with frequent traffic jams, the resource may be closer to the lower limit, and during quiet driving on the highway - much higher.
Is it possible to change only the front pads without replacing the rear ones?
Yes, front and rear brakes wear out at different rates. Typically, the front pads wear out faster due to the fact that they bear the brunt of the load during braking. The rear ones are changed less frequently, depending on their condition.
What to do if a squeaking noise appears after replacing the pads?
Creaking can occur for several reasons: lack of lubrication on the contact pads, the need to grind in new pads, or the use of low-quality spare parts. Try adding a special lubricant to the metal-to-metal contact areas.
Do I need to wipe brake discs when replacing pads?
Preferably. Wipe the rims with a clean cloth to remove any layer of brake dust and dirt. This will ensure better contact between the new pad and the disc, and will also reduce the risk of squeaking and vibration.
How to check that the pads are installed correctly?
After installation, press the brake pedal several times until it stops. It should become hard. There should be no extraneous sounds when driving, and the car should stop smoothly, without pulling to the side.
