Car brake system Nissan Note - This is a critically important unit, the health of which depends on your safety and the safety of others. In urban driving conditions with frequent traffic jams and sudden braking, rear brakes wear out faster than many expect. Ignoring signs of wear can lead to brake rotor failure, which results in much more expensive repair work.
Many crossover owners Nissan Note It is believed that the rear pads last forever, since the load on them is less than on the front ones. However, even with gentle operation, the resource of these consumables is limited. Regular diagnostics and timely replacing pads - this is the key to stable operation of the entire system and the absence of unpleasant creaking or vibration when braking.
The replacement procedure does not require sophisticated professional equipment, but does require certain skills in working with automotive equipment. In this article we will look in detail at how to replace the rear brake elements yourself, what tools you will need and what you should pay special attention to when choosing parts for Nissan Note.
Symptoms of wear and diagnosis of rear brakes
You can determine the need for replacement not only by mileage, but also by characteristic signs in the behavior of the car. The most obvious signal is the appearance of a specific metallic squeak or grinding noise, which intensifies when you press the brake pedal. This sound is caused when a worn pad begins to rub against the disc with a metal part designed to indicate wear.
In addition to noise, the driver may notice a decrease in braking efficiency or vibration in the pedal. If the brake system indicator lights up on the dashboard, this may indicate complete wear of the friction linings. Some models Nissan Note a wear sensor is provided that closes the circuit when a critical minimum material thickness is reached.
Visual inspection is the most reliable way to ensure the condition of the nodes. Through the window in the brake caliper you can evaluate the thickness of the friction lining. If it has become thinner than 2-3 millimeters, further use is unacceptable. It is also worth paying attention to the presence of oil stains or traces of brake fluid on the discs, which may indicate a caliper leak.
Selection of consumables and necessary tools
Before starting work, it is important to select the correct set of spare parts. For Nissan Note fit like original pads with article number D5500-1HA0A, as well as high-quality analogues from trusted brands such as Nipparts, Tek or TRW. Original parts provide an ideal balance between braking force and service life, but are more expensive than analogues.
- 🛠️ Socket set with extensions (sizes 12, 14, 17, 21 mm) - for dismantling the caliper and wheel.
- 🛠️ Brake Lubricant (high temperature) - for processing guides and the back side of the pads.
- 🛠️ Piston compression or a special vice clamp - for installing new, thicker pads.
- 🛠️ Brake cleaner — to remove dust and dirt from the disc and caliper before installation.
Also don't forget to check the condition of the brake discs. If they have deep marks or grooves, they need to be sharpened or replaced. Installing new pads on worn discs will lead to rapid failure of the new friction linings and unstable braking.
Step-by-step instructions for replacing rear pads
The replacement process begins with preparing the car. Install Nissan Note on a level surface, apply the handbrake and place wheel chocks under the front wheels. Raise the rear of the car with a jack and remove the wheel. Be sure to look under the hood and check the brake fluid level in the reservoir, as when the piston is pressed in, the level may rise and flow out through the neck.
Next you need to remove the caliper. Remove the two guide bolts holding the caliper bracket in place. Be careful: the bracket may be under load. Remove it and hang it on a wire so as not to damage the brake hose. Old pads are easily removed from the guides, but sometimes they stick and require careful prying with a screwdriver.
Before installing new elements, it is necessary to prepare the caliper piston. Unlike front brakes, rear pistons on most models Nissan Note They are threaded and require turning when pressed in. Use a special tool or utility pliers to compress the caliper pistons.
Clean the seats from old dust and dirt. Apply a thin layer of high temperature grease to the caliper guides and the metal parts of the pads that contact the caliper. Never allow lubricant to come into contact with the working surface of the friction lining or brake disc!
Install the new pads into place, making sure they move freely in the guides. Press the caliper bracket and tighten the guide bolts to the required tightening torque. Install the wheel and lower the car. After completing the work, press the brake pedal all the way down several times so that the pistons take their working position.
☑️ Preparation and dismantling
Avoid sudden braking in the first 100-200 kilometers.
- Brake pads
- Filters
- Oil
- Only at the service station
⚠️ Attention! When working on the brake system, never press the brake pedal while the caliper bracket is removed. This will cause the piston to completely come out of the housing and cause a loss of brake fluid.
Features of working with the rear caliper Nissan Note
Rear caliper design Nissan Note has its own nuances, which often become a stumbling block for beginners. The rear caliper piston is not simply pressed in, but simultaneously pressed in and rotated clockwise. If you try to compress it without turning it, you can strip the threads of the parking brake drive mechanism.
For the correct procedure for compressing the piston, it is best to use a special tool for brake calipers, which has adapters for scrolling. If you don’t have such a tool, you can use universal pliers or even old pads and a clamp, pressing them against the piston and turning it with a wrench if access allows. The main thing is to act smoothly, without jerking.
It is also worth paying attention to the handbrake mechanism. On some modifications Nissan Note The handbrake is operated by a cable, which can jam or stretch. If, when installing new pads, the cable does not release the piston completely, it may be necessary to adjust the cable tension or lubricate the mechanism inside the caliper.
Before starting work, take a photo of the location of the springs and pad retainers so as not to get confused during assembly, especially if the design looks complex.
If you are not confident in your abilities or do not have a suitable tool for turning the piston, it is better to entrust this work to professionals. An error in working with the rear mechanism can cost you to replace the entire caliper assembly, which is significantly more expensive than the cost of work.
Maintenance and Prevention
Regular maintenance is essential to extend the life of your brake system. Once a year, it is recommended to remove the calipers, clean the guides of old grease and dirt, and apply a new layer of high-temperature grease. This will prevent the pistons from seizing and uneven pad wear.
It is also worth monitoring the condition of the brake fluid. It is hygroscopic and over time absorbs moisture from the air, which lowers its boiling point and can lead to brake failure under heavy use. The fluid should be replaced every 2-3 years or according to the manufacturer’s regulations Nissan.
Be careful about your driving style. Frequent and sudden braking in traffic jams leads to overheating of discs and pads, which accelerates their wear. If possible, try to brake smoothly, using the inertia of the car, and keep your distance to avoid emergency situations.

⚠️ Attention! Use only specialized lubricants for brake systems. Conventional lubricants (Litol, Solidol) are destroyed at high temperatures and can cause the caliper to jam.
Regular lubrication of the caliper guides and monitoring the condition of the brake fluid extends the life of the brake system by 30-40%.
Common mistakes when replacing yourself
Beginners often make mistakes that can lead to a repeat visit to the service or an emergency. One of the most common mistakes is incorrectly installing the pads. Some models have special spring clips or soundproofing plates that cannot be ignored. If you don't install them, the pads will start to rattle and squeak.
Another mistake is ignoring the condition of the guide boots. If the boot is torn, water and dirt will get inside the caliper, which will lead to corrosion and jamming of the piston. Before installing new pads, be sure to check the integrity of the rubber seals and replace them if necessary.
Incorrect tightening of bolts is also unacceptable. Tightening it too loosely will cause the caliper bracket to unscrew while moving, while tightening it too tightly can strip the threads or deform the part. Always use a torque wrench and follow the tightening torque values specified in the instruction manual. Nissan Note.
