Operating a compact hatchback Nissan Note inevitably leads to wear on the chassis components, and the rear brake system here requires special attention. Many owners experience rear brakes that wear unevenly or require frequent adjustment, especially on models with an electronic parking brake.
Ignoring signs of malfunction can lead to seized calipers, overheating of the discs and, in the worst case, complete loss of braking efficiency on the rear axle. Proper maintenance is not just replacing consumables, but a comprehensive check of the mechanisms, lubrication of the guides and correct adjustment.
In this article, we will look at all the intricacies of working with the rear brake system, from diagnosis to final break-in, so that you can safely and economically extend the life of your car.
Design and features of the rear brake system
Rear brake system Nissan Note has its own design nuances, which depend on the year of manufacture and configuration. Most versions have disc brakes with a floating caliper, but earlier or budget versions may have drum brakes.
A feature of modern models is the integration of the parking brake mechanism directly into the caliper. This means that replacing pads often requires a special diagnostic scanner or adaptation via Menu → Settings → Maintenance to remove the piston. Without this physical force, the piston cannot be returned without damaging the mechanism.
It is important to understand that electronic brake It works on the principle of a servo drive, which presses the pads against the disc. If you manually press the piston without deactivating the maintenance mode, you can break the gears of the gearbox, which will lead to expensive repairs.
Diagnosis of wear and symptoms of malfunction
The need for maintenance can be determined by a number of indirect and direct signs that appear during operation. A squeak, squeak or metallic clang when you press the brake pedal is the first signal that pads have reached critical wear.
If you feel the steering wheel wobbling or the body vibrating when braking, the problem most likely lies in deformation brake disc. On Nissan Note Discs often become deformed due to overheating or improper tightening of the mounting bolts after replacement.
Uneven wear of the pads (one side is more worn than the other) indicates jammed caliper guides or problems with the piston. In this case, simply replacing consumables will not solve the problem; a complete revision of the unit is required.
- 🔍 Visual inspection through the wheel rim: the thickness of the friction lining is less than 2-3 mm requires urgent replacement.
- 🔊 Knocking or squeaking noise when moving: indicates a backlash in the caliper or wear on the damping plates.
- 🛑 The car pulls to the side when braking: a sign of a non-working caliper on one of the sides.
You should not wait until the friction layer is completely erased, since the metal base of the pad can seriously damage the working surface of the disc, which will require its replacement or grooving.
Selection of consumables and original analogues
Choosing the right components is the key to long and safe brake operation. Original pads Nissan (catalog numbers often start with D1060 or D1100) are distinguished by a stable composition of the friction material, but are not cheap.
There are many high-quality analogues that offer the best value for money. Check out brands that specialize in Japanese cars, such as ATE, TRW or Nisshinbo.
When choosing disks, it is important to consider their geometry and material. For city use, standard ventilated discs are suitable, but for a more aggressive driving style, it is worth considering perforated or ceramic options, although they require more careful grinding.

Step-by-step instructions for replacing brake pads
The process of replacing rear pads Nissan Note with an electronic handbrake requires strict adherence to the sequence of actions. Start by safely raising the vehicle on a lift or jack and removing the wheel.
Before starting work, you must connect a diagnostic scanner and put the calipers into maintenance mode. If you don't have a scanner, you can use a special tool to press out the piston, but only after you make sure that the mechanism is not blocked by electronics.
Clean the caliper guides of old grease and dirt. Apply new high temperature grease, such as silicone or copper based, to the contact surfaces and guide pins.
- 🛠️ Use a torque wrench to tighten the caliper mounting bolts (usually 25-30 Nm).
- 🧼 Be sure to clean the hub seat from rust before installing the disc.
- ⚙️ Check the condition of the guide boots; if there are cracks, replace the repair kit.
Install the new pads, making sure that they move freely in the caliper and do not touch the disc when the wheel rotates. After assembly, press the brake pedal several times until the pistons are in working position.
☑️ Preparing to replace pads
Repair and maintenance of brake discs
If you find deep grooves on the surface of the disc or visible signs of overheating (blue tint), you need to replace brake disc. Grooving is possible only if the thickness of the disk allows this to be done without compromising its strength.
When replacing discs, this will ensure uniform braking and prevent skidding. Do not install a new disc on a worn pad and vice versa.
The disc mounting bolts must be tightened to the recommended torque. On Nissan Note this is usually about 100-120 Nm, but the exact value should always be clarified in the service book of a specific year of manufacture.
⚠️ Attention: Never use WD-40 or regular motor lubricant to clean brake discs! Use only special brake cleaners to avoid damaging friction properties.
What happens if you don't replace the disk on time?
If you continue to drive with a worn disc, the pads can quickly wear out, and the caliper itself can become deformed from overheating, which will lead to the wheel seizing while driving.
Setting the electronic parking brake
The most critical stage is the correct setting of the electronic handbrake. If you simply inserted new pads and did not calibrate the mechanism, the servo may not work correctly.
It is necessary to carry out the initialization procedure via the diagnostic interface. The device menu often contains an item Service Mode, where you can select the "Rear Brake Caliper - Reset/Learn" function.
After completing the procedure, check the operation of the handbrake on an incline. The car should confidently hold on the slope, and the brake pedal should not fall below its normal position.
If the handbrake indicator on the dashboard flashes or stays on continuously after replacement, this indicates an error in the system that needs to be corrected with a scanner.
⚠️ Attention: An error in setting the caliper electric motor can lead to its failure. If you are not confident in your abilities, entrust this stage to professionals.
Calibration of the electronic handbrake is required after replacing the pads, otherwise the mechanism may jam or not work when parking.
Recommended Maintenance Interval Chart
To keep your brake system in perfect condition, it is recommended that you adhere to the following inspection and replacement intervals. These data are averages and may vary depending on driving style and operating conditions.
| Component | Check interval | Replacement interval | Special conditions |
|---|---|---|---|
| Brake pads | Every 10,000 km | 20,000 – 40,000 km | For frequent city trips |
| Brake discs | Every 20,000 km | 60,000 – 100,000 km | Depends on thickness and surface condition |
| Brake fluid | Every 2 years | Every 2-3 years | Air humidity affects service life |
| Caliper guides | Every 40,000 km | As it wears out | Checking boots and lubrication |
Regular level check brake fluid is also important, since its decrease may indicate pad wear or a leak in the system.
Frequently asked questions from Nissan Note owners
Owners Nissan Note Often asked questions related to the features of the rear brake system. Let's look at the most popular ones to save your time and avoid mistakes.
Is it possible to replace pads without a scanner with models with an electronic handbrake?
Technically this is possible using a special mechanical tool (swing) to press the piston, but there is a high risk of damage to the gear mechanism inside the caliper. It is recommended to use a diagnostic scanner to enter maintenance mode.
Why do rear brakes squeak after replacement?
The squeaking noise can be caused by a lack of lubrication on the metal parts of the pad, the presence of air in the system, or the need to grind new pads into the disc. Usually the squeak disappears after 200-300 km.
What brake disc thickness is considered critical?
The minimum permissible rim thickness is indicated on the rim itself (usually about 9-10 mm for rear rims Nissan Note). If the disk is thinner than this value, it must be replaced, as it may crack from overheating.
Do I need to change the brake fluid when replacing the pads?
Not necessary if the fluid has not expired and is not contaminated. However, if you are overhauling the caliper or changing hoses, a complete fluid change and bleeding of the system is required.
Before starting work on replacing brakes, be sure to clean the wheels from dirt and check the condition of the caliper boots - this is often overlooked, but is critical for the durability of the mechanism.
