Nissan Note E11 is a compact and maneuverable hatchback that has gained popularity due to its efficiency and reliability. However, like any car, it requires regular maintenance of the brake system. Brake drums are a critical element, the condition of which determines not only braking efficiency, but also safety on the road. In this article we will analyze all the nuances: from signs of wear to step-by-step replacement taking into account the features of the model E11.
Unlike disc brakes, drum brakes are less noticeable in operation, but their wear can lead to serious consequences - from increased braking distance to complete system failure. Owners Nissan Note Often faced with the question: when exactly is replacement required? How to choose high-quality spare parts among dozens of offers on the market? And is it possible to cope with the work independently, without resorting to the services of a service station? The answers are below.
Brake drum design Nissan Note E11: what you need to know
A brake drum is a cylindrical cast iron or steel part containing brake pads and the working cylinder. When you press the brake pedal, the pads are pressed against the inner surface of the drum, creating friction and slowing the wheel. B Nissan Note E11 drum brakes installed only on the rear axle (the front one is equipped with disc mechanisms), which is typical for cars of this class.
Design Features E11:
- 🔧 Drum diameter: 200–203 mm (depending on year of manufacture and configuration).
- 📏 Wall thickness: minimum permissible - 2 mm (if worn below, replacement is required).
- 🔄 Self-regulation system: in reels Note E11 There is a mechanism for automatically adjusting the gap between the pads and the drum.
- 🛠️ Material: High-strength cast iron with alloying additives for resistance to overheating.
It is important to consider that drums Nissan Note E11 are not interchangeable with models of other generations (for example, E10 or E12). Even externally similar parts may differ in seating dimensions or fastening design. When purchasing spare parts, always check VIN code car or check the manufacturer's catalogs.
- Every 10,000 km
- Once a year
- Only when problems arise
- Never checked
Signs of Wear: When to Replace Drums
Drum brakes wear out gradually, and their failure is not always obvious. However there are several key symptoms, which signal the need for diagnostics:
1. Increased braking distance. If the car starts to brake worse, especially on wet roads, this may indicate wear on the inner surface of the drum or pads. Unlike disc brakes, drum mechanisms are more sensitive to moisture and dirt.
2. Vibration or knocking when braking. Most often caused uneven wear drum (for example, due to overheating or corrosion). If you feel a wobble in the steering wheel, the problem is most likely in the front discs. If the vibration comes from behind, the drums are to blame.
3. Creaks, grinding or knocking noises from the rear wheels. These sounds may indicate:
- 🔊 Pad wear to the metal base (requires urgent replacement!).
- 🔊 Entry of foreign objects into a drum (stones, sand).
- 🔊 Drum deformation due to overheating (for example, after a long descent from a mountain).
4. Brake fluid leakage near the rear wheels. This is a sign of a problem working cylinder, but is often accompanied by wear of the drum, as the liquid corrodes the metal.
⚠️ Attention! If after replacing the pads the braking distance has not improved and the drums have deep grooves or cracks, they definitely need to be replaced. Polishing or grooving in this case is a temporary solution, which can lead to jamming of the mechanism.
How to check the drum without removing the wheel?
Press the brake pedal and turn the wheel by hand. If it locks with a delay or unevenly, this is a sign of wear on the drum or pads. Also pay attention to the wheel play: if it exceeds 1–2 mm, diagnostics of the bearing and brake mechanism is required.

⚠️ Attention! Do not buy drums that show signs of corrosion or chips - even small defects can lead to cracking when heated. Also avoid universal "one size fits all Nissan" parts - they rarely fit perfectly.
Before purchasing, compare the old and new drums by mounting holes and diameter. Even if the article numbers are the same, the geometry may differ between batches.
Step-by-step instructions for replacing brake drums
Replacing drums with Nissan Note E11 - a task of medium complexity that requires accuracy and consistency. If you have the tools and minimal experience working with the brake system, you can handle it in 2–3 hours.
Required tools:
- 🔧 Set of sockets and keys (10, 12, 14, 17 mm).
- 🔨 Hammer (rubber or metal with a wooden spacer).
- 🔩 Puller for brake drums (or two bolts M8×1.25).
- 🧲 Magnet for fastening (so as not to lose small parts).
- 🧴Brake fluid
DOT-4and brake cleaner.
Sequence of work:
- Preparation: Place the car on a level surface, tighten the handbrake and place chocks under the front wheels. Loosen the rear wheel nuts.
- Removing the wheel: Raise the car with a jack, remove the wheel and clean the brake mechanism from dirt.
- Removing the drum:
- Remove the hub protective cap (if equipped).
- Unscrew the guide pins (if the drum is stuck, use a puller or gently tap the edges with a hammer).
- Inspection and replacement:
- Check the condition of the pads and working cylinder.
- Install a new drum, having previously lubricated the seats
copper grease(without getting on the work surface!).
80–100 Nm, bleed the brakes and check the system for leaks.Clean the hub seating surface from rust |
Check wheel bearing play|
Lubricate the pad guides with special lubricant|

After replacement necessarily:
- 🚗 Test the brakes at low speed (5–10 km/h), gradually increasing the load.
- 🔧 Bleed the brake system if you notice a decrease in efficiency.
- 📝 Record mileage and replacement date to track service intervals.
If the drum does not come off despite all efforts, do not use excessive force as this may damage the hub. In this case, use a penetrating lubricant (for example, WD-40) and give it time to act (10–15 minutes).
Common replacement mistakes and how to avoid them
Even experienced car owners sometimes make mistakes that lead to premature wear drums or brake failure. Here are the most common of them:
1. Ignoring pad condition. Installing new drums on worn pads will quickly damage them. Always change pads and drums in pairs (even if one of them looks ok).
2. Incorrectly tightened fasteners. Weak tightening will lead to vibrations, and excessive tightening will lead to deformation of the drum. Use torque wrench and observe the tightening torques (for Note E11 — 80–100 Nm for the hub nut).
3. Grease getting on the work surface. Even a small amount of grease or brake fluid on the drum or pads will dramatically reduce braking performance. Clean parts only special brake cleaner.
4. Unbleeded brake system. After replacing the drums, air can get into the hydraulic drive, which will lead to a “soft” brake pedal. Pumping is required!
5. Use of incompatible parts. For example, installing drums from Nissan Micra instead of the original ones for Note E11. Even if they look similar, differences in diameter or wall thickness will cause the brakes to not function properly.
What to do if the brakes squeak after replacing the drums?
The creaking can be caused by:
- Poor quality pads (choose pads with soft friction linings).
- Dirt getting between the block and the drum (disassemble the mechanism and clean it).
- Incorrect installation of springs or spacers (check the diagram).
In most cases, the squeak goes away after running in (100–200 km), but if it gets worse, repeated diagnostics are required.
Service life and prevention: how to extend the life of drums
Average brake drum life Nissan Note E11 amounts to 80,000–120,000 km, but this indicator strongly depends on driving style And operating conditions. To delay replacement as much as possible, follow these recommendations:
1. Avoid hard braking. Drum brakes dissipate heat worse than disc brakes, so heavy braking leads to overheating and deformation.
2. Clean the mechanism regularly. Dirt and salt from roads in winter accelerate corrosion. Flush the brakes every 10,000 km special cleaner.
3. Check the brake fluid level. Its low level or contamination leads to incorrect operation of the working cylinder, which accelerates drum wear.
4. Check the handbrake adjustment. If the handbrake is too tight, the shoes will constantly rub against the drum, increasing wear.
5. Use quality spare parts. Cheap pads or drums made of low-quality metal wear out 2-3 times faster.
6. Keep an eye on the wheel bearing. Its play or wear leads to uneven contact of the pads with the drum, which accelerates the formation of grooves.
| Factor | Impact on drum life | How to minimize harm |
|---|---|---|
| Aggressive riding | Reduces service life by 30–40% | Use the engine to brake (lower gear) |
| Operation in the city | Frequent braking accelerates wear | Keep your distance, avoid a “ragged” driving style |
| Winter operation | Salt and moisture cause corrosion | Flush your brakes in the spring, use anti-corrosion lubricants |
| Vehicle overload | Increases load on the rear axle | Do not exceed the permissible weight (for Note E11 — 400 kg per axle) |
FAQ: Frequently asked questions about brake drums Nissan Note E11
Is it possible to sharpen the drums instead of replacing them?
Grooving is possible if the drum wall thickness is not less than 2 mm after processing. However for Nissan Note E11 this is rarely justified, since the cost of a new part is comparable to the cost of turning, and the service life after restoration will be lower. Grooving is recommended only to eliminate minor furrows (up to 0.5 mm deep).
Which brand of drums is better to choose: original or analogue?
Original drums (Nissan 40520-BM400) guarantee perfect compatibility, but their price is often too high. High-quality analogues (Akebono, Brembo, TRW) are in no way inferior in resource, and sometimes even surpass the original (for example, Brembo has improved heat dissipation). The main thing is to avoid cheap no-name brands.
Do I need to change drums in pairs?
Yes, necessarily! Replacing only one drum will result in uneven braking and pulling the car to the side. The exception is if the second drum is practically new (less than 10% wear), but even in this case a pair is recommended.
What should I do if the brake pedal becomes soft after replacing the drums?
This is a sign air entering the brake system. It is necessary to bleed the brakes, starting with the rear right wheel. If the problem persists, check the tightness of the working cylinders and hoses.
How often should the condition of the drums be checked?
Minimum frequency - every 20,000 km or once a year. If you often drive on mountain roads or in high humidity conditions, reduce the interval to 10,000–15,000 km. Also check the drums every time you change the pads.
