Brake drums are a key element of the rear braking system. Nissan Almera Classic (including modifications B10 And N16 from 2006 to 2012). Unlike disc brakes, drum mechanisms are less noticeable in operation, but their wear is fraught with serious consequences: from an increased braking distance to complete system failure. Owners Almeri Classic often encounter problems: squeaking when braking, wobbly steering wheel or uneven wear of the pads - all this may indicate a problem with the drums.
In this article we will analyze how to diagnose wear, which drums to choose (original vs analogues from ATE, TRW, Brembo), how to replace them yourself and avoid common mistakes. We will pay special attention unique features of Almera Classic: compatibility of drums with the ABS system and specific bearing mounting - this nuance is often missed even by experienced craftsmen. We will also provide current prices, article numbers and step-by-step instructions with photos.
Signs of brake drum wear on a Nissan Almera Classic
The first signal about problems with the drums is vibration on the brake pedal or the steering wheel during heavy braking. This occurs due to deformation of the working surface of the drum (the so-called “oval”), which occurs when overheated. For example, if you frequently brake on downhill slopes or tow a trailer, the risk of deformation increases by 3 times.
Other symptoms:
- 🔊 Creaking or grinding when reversing (the pads rub against the side of the worn drum).
- 🚗 Pulling the car to the side when braking (different wear on the left and right drums).
- 🛑 Increased braking distance — the pads cannot press tightly against the deformed surface.
- 💨 Rear wheel overheating after intense braking (the drum “drives” and rubs against the pads).
Critical wear is determined by drum inner diameter. For Almera Classic limit value - 201.5 mm (at nominal 200.0 mm). An excess of even 0.5 mm requires mandatory replacement. You can check this with a caliper or at a service station using a special stand.
⚠️ Attention: If deep grooves (more than 1 mm) appear on the inner surface of the drum, it cannot be machined - this will weaken the metal structure and lead to cracks. In such cases, only replacement!
- Once every 10,000 km
- Only when squeaks appear
- Never checked
- Only for maintenance
Original vs analogues: which drums to choose for Almera Classic
Original drums from Nissan (article 40520-9M000 for front-wheel drive versions and 40520-9M001 for all-wheel drive) cost from 4,500 to 6,000 rubles apiece. Their main advantage is guaranteed compatibility with the system ABS and the original wheel bearing. However, many owners choose analogues, which are 30–50% cheaper, but are not always inferior in quality.
The best analogues for Almera Classic:
| Brand | Article | Price (per piece), ₽ | Features |
|---|---|---|---|
| ATE | 24.0126-0160.2 |
3 200–3 800 | High quality cast iron, suitable for intensive use |
| TRW | GDB1401 |
3 500–4 100 | Reinforced construction, ABS compatible |
| Brembo | 09.9566.11 |
4 000–4 700 | Optimized for high temperatures, minimal risk of deformation |
| Fenox | DB10007O |
2 500–3 000 | Budget option, suitable for a relaxed driving style |
When choosing an analogue, pay attention to markings on the body: original drums are engraved NISSAN and catalog number. Cheap counterfeits (for example, from NoName-brands) there is often no balancing mark, which leads to vibrations during braking.
Before purchasing, check the package contents: the box should contain a drum, mounting bolts and instructions. Some manufacturers (for example, ATE) put a special lubricant for the guide pads - do not throw it away!
Step-by-step instructions for replacing brake drums
Replacing drums with Nissan Almera Classic requires a minimum set of tools: jack, wheel wrench, socket head 17 mm, socket wrench on 12 mm, a flat blade screwdriver and bearing puller (if you plan to change the wheel bearing). It is better to carry out the work on a pit or a lift, as access to the brake hoses will be required.
Sequence of actions:
- Removing the wheel and drum:
- 🔧 Loosen the wheel nuts, jack up the car and remove the wheel.
- 🔩 Unscrew the drum guide pins (2 bolts on
12 mm). - 🛠️ Knock the drum off the hub with light blows of a hammer through a wooden spacer (do not hit metal!).
- Diagnostics and preparation:
- 🔍 Inspect the pads: if their thickness is less than
1.5 mm, replace them too. - 🧴 Clean the hub from rust and old grease (use
WD-40or acetone).
- 🔍 Inspect the pads: if their thickness is less than
- Installing a new drum:
- 🔄 Place the drum on the hub and secure it with the guides.
- 🔩 Tighten the bolts crosswise firmly
80–100 Nm.

After replacement be sure to bleed the brakes (even if the hydraulic drive was not opened). To do this:
- Start the engine.
- Press the brake pedal 5–7 times at 2 second intervals.
- Check the brake fluid level in the reservoir (should be between
MINAndMAX).
⚠️ Attention: If the brake pedal becomes soft after replacing the drums, this is a sign of air getting into the system. Complete bleeding of the brakes is required with an assistant or at a service station!
What to do if the drum cannot be removed?
If the drum is stuck to the hub, do not hit it with a hammer - you risk damaging the bearing. Instead:
1. Treat the joint with penetrating lubricant (Liqui Moly or PB Blaster).
2. After 15 minutes, carefully pry the drum with a pry bar at the attachment points.
3. If this does not help, use a three-jaw puller (for example, KUKKO 205-3).
Typical replacement mistakes and how to avoid them
Even experienced car owners make mistakes that lead to premature drum wear or brake failure. Here are the most common:
1. Ignoring the handbrake adjustment. After installing new drums, the gap between the pads and the drum increases, which is why the handbrake may not hold. Solution: Adjust the cable tension through the adjusting bolt under the car (accessible from under the rear of the body).
2. Using unsuitable lubricant. Some people lubricate the pad guides Lithol or Solid oil, which coke at high temperatures. The right choice is brake lubricant (For example, Molykote G-3407 or Slipkote 220-R DBC).
3. Failure to comply with the tightening torque. Overtightened drum mounting bolts lead to its deformation, and weak tightening leads to vibrations. Use a torque wrench with force 80–100 Nm.
4. Neglecting to check the bearing. If you hear a crunch or play when the drum rotates, the hub bearing requires replacement. Its article number is for Almera Classic — 40520-9M002 (original) or SKF VKBA 3588 (analog).
After replacing the drums, avoid sudden braking for the first 200 km - the pads need to get used to the new surface.
How to extend the life of your brake drums
Average drum resource per Nissan Almera Classic — 80,000–120,000 km, but with aggressive use it is reduced to 50,000 km. To delay replacement as much as possible:
- 🚘 Avoid prolonged wear-and-tear braking. For example, on descents it is better to use engine braking (turn on a lower gear).
- 💧 Monitor the condition of the brake fluid. It is hygroscopic and after 2 years it accumulates moisture, which reduces the boiling point and accelerates the wear of the drums. Change the fluid every
40,000 kmor once every 2 years. - 🔧 Clean your brakes regularly. Dirt and sand between the shoe and the drum act as an abrasive. Once every 10,000 km, remove the drums and blow them with compressed air.
- ❄️ Avoid sudden temperature changes. For example, after intense braking, do not immediately drive into a puddle - this will lead to microcracks on the drum.
One more thing: if you often drive off-road or in high humidity conditions, treat the drums anti-corrosion composition (For example, Dinitrol 409). This will prevent the inner surface from rusting, which will accelerate pad wear.
When washing your car, avoid directing a stream of water onto the brake drums - this will wash the lubricant out of the bearing and lead to its premature failure.
Cost of service work vs independent replacement
Price for replacing brake drums Nissan Almera Classic in service depends on the region and level of the service station. On average:
- 🔧 Cost of work (for 1 drum): 1 500–2 500 ₽.
- 🔧 Replacing pads (rear set): 800–1 500 ₽.
- 🔧 Bleeding the brakes: 500–1 000 ₽.
Total, including spare parts (for example, drums ATE 3,500 ₽/piece. and pads Ferodo for 1,200 ₽), the total cost at the service station will be 12 000–16 000 ₽. If you replace it yourself, you will save up to 50%, but you will need tools and time (on average 3-4 hours for both wheels).
Where is the best place to buy spare parts?
| Source | Pros | Cons |
|---|---|---|
| Official dealer | Warranty for original spare parts, VIN check | Prices are 20–30% higher than analogues |
| Online stores (Exist.ru, Autodoc) | Wide range, prices are 15–25% lower | Risk of running into a fake, long delivery |
| Spare parts markets | You can bargain, sometimes you come across used ones in good condition | No guarantee, high risk of counterfeit |
Frequently asked questions about Nissan Almera Classic brake drums
Is it possible to sharpen the drums instead of replacing them?
Grooving is possible if the thickness of the drum wall after processing remains at least 3.5 mm (denomination - 4.0 mm). However, on Almera Classic this is rarely justified: the cost of grooving (1,000–1,500 rubles per piece) is comparable to the price of new drums from budget brands (Fenox, LPR). In addition, machined drums last 30% less.
What should be the gap between the block and the drum?
Nominal clearance for Almera Classic — 0.25–0.35 mm. If it is larger, the brakes will “grab” with a delay; if less, the pads will jam. You can adjust the gap through the eccentric on the brake shield (a special wrench or pliers are required).
Why do the brakes squeak after replacing the drums?
Creaking in the first 200–300 km is a normal phenomenon (grinding in the pads). If the sound does not disappear:
- Check to see if any dirt has gotten between the pad and the drum.
- Make sure the pads are installed with the correct side (they have markings
LAndRfor left and right wheels). - Apply to the back of the pads anti-squeak paste (For example, ATE Plastilube).
Do I need to change drums in pairs?
Yes, even if the wear is only on one wheel. Different degrees of wear on the left and right drums lead to uneven braking and the car pulling to the side. The exception is if you change the drum due to mechanical damage (cracks), and the second one is in perfect condition (which is unlikely).
Can I install drums from another Nissan model?
No. Drums from Nissan Note or Micra do not fit in fit dimensions and diameter. The only compatibility option is drums from Renault Logan/Sandero first generation (item 40520-9M000 identical), but a VIN check is required, as the ABS mounts may differ.
