Your car's security system should always be in perfect condition, especially when it comes to brake circuit. Nissan Almera N16, despite its venerable age, remains a popular choice in the secondary market due to its reliability and simplicity of design. However, like any mechanism, brakes require regular attention and timely intervention from a specialist. Ignoring signs of wear can lead to critical situations on the road.
Owners of this model often encounter typical problems: squeaking pads, beating of the steering wheel when braking, or increased pedal travel. Nissan Almera N16 has a specific suspension and brake architecture, which requires an understanding of the nuances during repair. The correct selection of spare parts and adherence to replacement technology are the key to your safety. In this article we will look in detail at how to maintain the brake system of this car.
Design and features of the Almera N16 brake system
Structurally, the front part of the car is equipped with ventilated disc brakes, which provides effective cooling during intense driving. The rear axle, depending on the configuration, may have either disc or drum brakes, which is a common question among buyers of used vehicles. Basic versions with a 1.4-liter engine are characterized by drum mechanisms at the rear, which are easier to maintain but require more frequent clearance adjustments.
The key element of the system is master brake cylinder, located under the hood, which converts pedal force into hydraulic pressure. The hydraulics are routed diagonally, which allows you to maintain braking efficiency even if one of the lines is damaged. ABS (anti-lock braking system) on many versions Nissan Almera N16 is standard equipment, significantly improving handling on slippery surfaces.
It is important to understand that the system does not work in isolation. The condition of the calipers directly affects the wear of the pads and discs. If the caliper guides become sour, the pad stops moving away from the disc, which leads to overheating and rapid destruction of parts. Regular lubrication of the guides and checking the boots is a mandatory procedure for any maintenance.
Many owners underestimate the role of brake fluid, believing that it lasts forever. In fact, it is hygroscopic and absorbs moisture from the air through the pores of rubber hoses and seals. Water entering the system reduces the boiling point of the fluid, which during sudden braking can cause vaporization and loss of braking force. The fluid must be changed strictly according to the regulations, without waiting for visible signs of a malfunction.
Choice of components: original or analogues?
The spare parts market offers a huge selection of options for Nissan Almera N16, from cheap Chinese production to premium European brands. The original (Nissan) always guarantees compliance with factory specifications, but the price may be inflated due to logistics and branding. However, in the case of brakes, savings can result in serious problems with safety and comfort.
Among the popular analogues are brands that are often supplied to the assembly line or have an excellent reputation in the after-sales market. Please note the following manufacturers:
- 🔹 TRW - excellent calipers and pads, often come in original Nissan packaging.
- 🔹 Brembo — premium discs and pads that provide maximum braking.
- 🔹 Textar — reliable pads of balanced quality and price.
- 🔹 Febi Bilstein - A good option for drum brakes and consumables.
When choosing brake discs, it is important to pay attention not only to the brand, but also to the design. Ventilated discs on the front axle are critical to prevent overheating. Thin disks deform faster from thermal loads. For city use, standard solid or ventilated discs are suitable, but for sports driving it is worth considering perforated or notched options.
Don't forget about the brake fluid. Use only standard fluid DOT 4recommended by the manufacturer. Mixing fluids of different brands or standards (for example, DOT 3 and DOT 5.1) is strictly prohibited, as this can lead to corrosion of the seals and system failure. Always check the release date on the canister, as the liquid loses its properties even in a closed package over time.
Diagnosis of faults and characteristic symptoms
You can identify problems with the brakes even before a service visit, simply by listening to the behavior of the car. A squeaking sound when you press the pedal most often indicates that the pads have worn down to a minimum level, when the metal base begins to rub against the disc. In some cases, squeaking is caused by vibrations or lack of lubrication on the back of the pads, which can be solved by installing anti-squeak plates.
Steering wheel wobble or pedal vibration when braking is a sure sign of brake disc deformation. This occurs due to local overheating and subsequent uneven cooling of the metal. If the disc has a runout of more than 0.05 mm, it must be ground or replaced. Trying to save money and simply replace the pads with a bent disc will not eliminate the vibration.
Increased pedal travel or a spongy pedal feel often indicates air in the system or a brake fluid leak. This could also be a sign of a problem. vacuum brake booster. Check the tightness of the hoses coming from the amplifier to the engine and the condition of the cuff. If the pedal becomes soft after several presses with the engine running, the booster most likely does not hold vacuum.
A car skidding to the side when braking indicates uneven braking of the wheels on one axle. This could be caused by a seized caliper piston, brake fluid leakage, or differences in pad wear. In this case, it is necessary to immediately check the condition of all calipers and the quality of the brake hoses, as the car may become uncontrollable.

Procedure for replacing front pads and discs
Replacing the front pads with Nissan Almera N16 does not require sophisticated equipment, but requires accuracy and attention to detail. Before starting work, be sure to secure the vehicle on a level surface and place chocks under the rear wheels. Loosen the wheel bolts with the vehicle raised to prevent the disc from spinning when removing the caliper bolts.
The caliper is removed by unscrewing the guide bolts located on the rear side. After removing the caliper, it must be hung on a wire or hook, under no circumstances allowing it to hang on the brake hose - this can damage the rubber part and lead to fluid leakage. Remove the old pads and check the condition of the bracket on which they are attached.
If you are also changing brake discs, you will need to unscrew the mounting screw that secures the disc to the hub (sometimes it is hidden under the wheel disc or jammed due to corrosion). Before installing a new disk, be sure to degrease its surface and clean the seat on the hub from rust. This will ensure proper contact and prevent the disc from wobbling.
When installing new pads, it is necessary to lubricate the caliper guides with a special high-temperature grease and check the condition of the boots. Anthers should not have cracks or tears. After assembly, be sure to press the brake pedal all the way down several times so that the caliper pistons are in place and the pads are in contact with the disc.
☑️ Preparing to replace pads
How to check the thickness of a brake disc?
To do this, use a micrometer or caliper. Measure the thickness of the disc in several places. If the value is below the minimum permissible thickness indicated on the disk itself or in the manual, it must be replaced. For Almera N16, the minimum thickness is usually 18-20 mm, depending on the modification.
Rear Brake Maintenance: Drum and Disc Options
Rear drum brakes on the Nissan Almera N16 have their own specifics, especially in terms of adjusting the gaps. The pads inside the drum are released by a release mechanism (wheel cylinder), and over time the gap increases, which leads to an increase in pedal travel. Adjustment is made through a special hole in the drum using a screwdriver and a slotted adjuster.
When replacing rear pads, it is important to check the condition of the return springs. Weakened springs do not return the pads to their original position, which causes them to constantly contact the drum and overheat. Also check the wheel cylinder for fluid leaks. Any drop of oil on the inside of the drum is a signal to immediately replace the cylinder and clean the drum.
If your car is equipped with rear disc brakes, then the replacement process is similar to the front, but with an important nuance: the handbrake mechanism is built into the caliper. The rear caliper piston must not only be pressed in, but turned with a special device or pliers, since it has a threaded connection. Simply pressing in without turning can break the handbrake mechanism.
Don't forget to check the condition of the handbrake cables. They often rust and jam, which is why the rear wheels may not unlock after parking. The cables must be lubricated and checked for damage to the braid. If the cable is jammed, it needs to be replaced, since trying to unscrew it can lead to a break and more complicated repairs.
Rear drum brakes require regular checking of the clearances and lubrication of the handbrake cables to avoid them jamming in winter.
Hydraulics and caliper maintenance
The hydraulic system requires regular bleeding to remove air. The air in the system is compressed, which makes the brake pedal soft and reduces braking efficiency. It is better to carry out bleeding with an assistant or use a vacuum pump. The bleeding order usually starts with the wheel furthest from the master cylinder: rear right, rear left, front right, front left.
Calipers are complex mechanisms consisting of pistons, guides and seals. At each maintenance (every 20-30 thousand km), the guides must be cleaned of old grease and dirt, and then lubricated with special silicone grease. The pistons should be pulled out and inspected for corrosion. Even slight rust on the piston mirror can damage the boot and lead to souring.
Brake hoses are the weak link in the system. Rubber ages over time, cracks and can burst under pressure. Inspect all hoses for bulges, cracks and traces of oil. If the hose has even minor damage, it must be replaced. Do not skimp on hoses, as their rupture when driving at speed will lead to complete loss of brakes.
It is also important to monitor the brake fluid level in the reservoir. If the level has dropped, this could mean either pad wear (the level drops naturally) or a leak. When replacing pads, the level may rise as the pistons move out, freeing up space in the reservoir. If the level drops quickly, look for a leak or check the reservoir for cracks.
| Component | Recommended replacement interval | Signs of wear | Recommended Brand |
|---|---|---|---|
| Front pads | 20,000 - 40,000 km | Creak, squeak, vibration | Textar, TRW |
| Brake discs | 60,000 - 80,000 km | Beating, grooves, thinning | Brembo, Bosch |
| Rear pads | 40,000 - 60,000 km | Reduced effectiveness of the handbrake | Febi, ATE |
| Brake fluid | 2 years (regardless of mileage) | Darkening, lower boiling point | Castrol, Motul |
| Caliper (repair kit) | When jammed | Overheating, uneven wear | Febi, TRW |
Before purchasing new calipers, be sure to check the markings on the old ones. On the Nissan Almera N16 there are different modifications of calipers, which may differ in piston diameter and mounting.
⚠️ Attention: Never use multi-purpose lubricants on caliper guides. Regular lithium grease or grease can dissolve the rubber boots, which will lead to the caliper jamming. Use only special high-temperature brake lubricant (usually blue or clear).
Common repair mistakes and how to avoid them
One of the most common mistakes is installing new pads on old, worn or warped discs. This will not only not give the expected result, but can also lead to rapid failure of the new pads. If the disc has more than 1 mm wear or runout, it must be sharpened or replaced. Ignoring the condition of the disc when replacing pads is the main reason for repeated visits to the service center within a month.
Another mistake is improperly tightening the caliper or disc mounting bolts. It is critical to use a torque wrench to tighten the caliper guide bolts and wheel bolts. Too much tightening can strip threads or deform parts, while too little tightening can cause the element to unscrew while moving. Always refer to the tightening torques specified in the repair manual.
Improperly bleeding the brakes can also lead to problems. If you do not follow the correct bleeding procedure or monitor the fluid level in the reservoir, air will enter the system and the brakes will no longer function effectively. It is also important not to allow the liquid to completely drain from the tank during pumping, as this will require a repeat procedure.
Ignoring the condition of boots and cuffs is another common cause of malfunctions. Anthers protect caliper pistons and guides from dirt and moisture. If the boot is torn, dirt gets inside, causing corrosion and jamming. When replacing pads, always inspect the boots and, if necessary, replace them with new ones, even if the caliper seems to be working.
FAQ: Answers to frequently asked questions from owners
Why do the brakes on the Nissan Almera N16 squeak even after replacing the pads?
Creaking can be caused by several reasons: poor-quality pads (too hard or with a hard compound), lack of anti-creaking plates, contamination of the working surfaces, or the need to grind in new pads. Check for any grease or dirt on the work surfaces. Sometimes it helps to lightly grind the pads (several sharp braking in a safe area) or replace them with higher quality materials.
How often should brake fluid be changed?
The manufacturer recommends changing the brake fluid every 2 years, regardless of mileage. This is due to the fact that the liquid is hygroscopic and absorbs moisture, which lowers its boiling point and can lead to corrosion of system elements. If you operate the car in difficult conditions, the interval can be reduced to 1.5 years.
Is it possible to install wheels from other Nissan models on Almera N16?
Theoretically, you can select wheels from other models if the parameters match (PCD, center hole diameter, offset), but this requires careful checking. A discrepancy between the parameters can lead to wheel runout, problems with the brakes, or even hitting the suspension components. It is better to use disks designed specifically for Almera N16, or proven analogues.
What to do if the brake pedal fails?
A sinking pedal most often indicates the presence of air in the system or a malfunction of the brake master cylinder. Try bleeding the brakes first. If the problem persists, check the master cylinder for internal fluid leakage. Also check the brake fluid level in the reservoir.
When replacing brake pads, always clean the seats on the caliper and caliper with a wire brush. This will ensure that the pads fit snugly and prevent them from jamming.
⚠️ Attention: Always use safety glasses and gloves when working with the brake system. Brake fluid is toxic and can cause burns or irritation to the skin and eyes. If liquid gets on your car's paintwork, wash it off immediately with plenty of water.
Proper maintenance of the brake system is not just a regulatory requirement, but a guarantee of your safety and the safety of others. Regular diagnostics, the use of high-quality spare parts and adherence to repair technologies will allow you to operate Nissan Almera N16 for many years without problems. Do not put off repairs until later if you notice the first signs of a malfunction, as brakes are unforgiving of mistakes.
