The braking system is one of the key safety components Nissan Almera Classic (including models B10 And N16 with engines 1.5/1.6 l). Brake discs are subject to enormous stress here: from stop-and-go traffic jams to aggressive driving on the highway. And if the owner changes the pads regularly, then the discs are often treated according to the “until they creak” principle. This is a dangerous misconception: a worn disc 1.5 mm below the minimum thickness increases the braking distance by 20–30% even with new pads.
In this article we will look at everything you need to know about brake discs for Almera Classic: how to determine critical wear, which brands to choose (from budget ABS up to bonus Brembo), how to replace discs yourself without errors, and why even high-quality parts can fail after 10,000 km. Let's look separately at typical problems - for example, why new discs vibrate when braking and how to avoid this.
Signs of worn brake discs: when is it time to change them?
The first signal about disk problems is steering wheel beating when braking at speeds above 60 km/h. This means that the disc has become deformed (called “driving”) or its thickness has become uneven. Other warning symptoms:
- 🔊 Creaking or grinding when pressing the pedal - often confused with pad wear, but a metallic sound may indicate grooves more than 0.5 mm deep on the surface of the disc.
- 🛑 Increased braking distance - if the car “floats” during emergency braking, even with new pads.
- 🔥 Brake overheating — after intense braking, the discs should cool down within 5–10 minutes. If they are hot after 30+ minutes, it is a sign of excessive wear or a stuck caliper.
- 📏 Visible defects: Cracks, deep scratches or a "shoulder" on the edge of the disc (thickening due to uneven wear).
For Nissan Almera Classic minimum permissible thickness of front discs - 18 mm (the rating for new ones is 20–22 mm depending on the manufacturer). Rear discs (if they are disc and not drum) have a minimum thickness 8 mm. You can check it with a caliper or even a coin: if the edge of the disk is thicker than 1 mm relative to the main surface, it’s time to change it.
⚠️ Attention: If there are radial cracks (from the center to the edge), it must be replaced immediately - even if the thickness is normal. Such defects lead to the disc splitting when heated.
- Once every 10,000 km
- Only when replacing pads
- When symptoms appear
- Never checked
Which brake discs are suitable for Nissan Almera Classic
On Almera Classic (including restyled versions) the following sizes of wheels are installed:
- 🔧 Front: diameter
256 mm, thickness of the new disk20–22 mm, bore diameter64.1 mm, number of holes4×114.3. - 🔧 Rear (for versions with disc brakes): diameter
232 mm, thickness9–10 mm, bore diameter64.1 mm.
Important: on basic trim levels Almera Classic (especially with engine QG15DE) rear brakes are often drum brakes. If you are planning to upgrade to disc, the entire hub and caliper will need to be replaced.
| Brand | Disk model | Type | Price (for 1 piece), ₽ | Features |
|---|---|---|---|---|
| Brembo | 09.9662.11 | Ventilated | 4 500–5 200 | High carbon alloy, resource up to 100,000 km |
| ABS | 50030 | Unventilated | 1 800–2 300 | Budget option, suitable for relaxed driving |
| TRW | DF4536 | Ventilated | 3 200–3 800 | Original quality for the conveyor Nissan |
| Bosch | 0 986 479 720 | Ventilated | 3 500–4 100 | Coverage Bosch Protective Coating against corrosion |
| Nipparts | N2610516 | Unventilated | 2 100–2 600 | Optimal price/quality ratio for the city |
When choosing, pay attention to disk type:
- 🌀 Ventilated — better heat dissipation, suitable for aggressive driving or frequent driving with a trailer. On Almera Classic installed on versions with engine QG16DE (1.6 l).
- 🟢 Non-ventilated - Cheaper and easier to manufacture, but cope worse with overheating. Installed on basic versions with QG15DE (1.5 l).
- 🛡️ Perforated/notched — improve grip with the pads, but wear out faster. For Almera Classic not practical - suitable for sports cars.
When purchasing discs, check them for beating right in the store: place the disc on a flat surface and spin. If there is any play or it is “loose”, refuse the purchase - this is a defect.
Step-by-step instructions for replacing brake discs
Replacing disks with Nissan Almera Classic does not require special equipment, but will require care. Main rule: change disks in pairs (both front or both rear), even if only one is worn. Otherwise, the car will pull to the side when braking.
Required tools:
- 🔧 Socket wrench for 17 and 19 mm (for caliper and hub).
- 🔧 12 mm socket wrench or socket (for caliper guides).
- 🔧 Jack and stops (or “goats”).
- 🔧 WD-40 or similar lubricant (sticky bolts).
- 🔧 Torque wrench (optional, for precise tightening).
Work order:
- Jack up the car and remove the wheel. Be sure to secure the machine with supports - even on a flat surface!
- Unscrew the two caliper bolts (usually 17 mm), remove it and hang it on a wire or rope so as not to damage the hose.
- Remove the brake pads (when replacing discs, it is also better to update them).
- Unscrew the two bolts securing the disc to the hub (19 mm). If they are stuck, use WD-40 and lightly tap the wood spacer with a hammer.
- Remove the old disk. If it is “grown” to the hub, gently tap the rim.
- Install the new disc, tighten the bolts crosswise firmly
80–100 Nm. - Reassemble the caliper in reverse order. After installation press the brake pedal several timesso that the pads fall into place.
Clean the hub from rust and dirt|Check the condition of the wheel bearing|Apply copper grease to the disc mating surfaces|Make sure the new pads are compatible with the discs|Bleed the brakes after assembly-->
⚠️ Attention: If after replacing the discs the brake pedal becomes “soft”, this is a sign air entering the system. It is necessary to bleed the brakes, otherwise braking efficiency will decrease by 40–50%.
Typical replacement mistakes and how to avoid them
Even experienced car owners make mistakes that lead to premature wear of the discs or incorrect operation of the brakes. Here are the most common:
- 🔩 Retightening the hub bolts - leads to disc deformation. Use a torque wrench or tighten by hand to a maximum torque of 100 Nm.
- 🧴 Lack of lubrication on the caliper guides — the pads will jam, which will accelerate disc wear. Use high temperature grease (For example, SLIPKOTE 220-R DBC).
- 🔄 Using old pads with new discs — mismatched surfaces will lead to uneven wear. Always change the pads along with the discs!
- 🚗 Neglect of running-in — for the first 200–300 km after replacement, avoid sharp braking so that the pads get used evenly.
Another common problem is hub corrosion. If you do not clean it of rust before installing a new disk, it will be installed skewed, which will lead to beating. To clean, use a wire brush or special drill attachments.
What should I do if vibration appears after replacing the disks?
Vibration when braking after replacing discs is usually associated with:
1. Incorrect tightening of the hub bolts — check the tightening torque.
2. New disk defect - even branded wheels can have a manufacturing defect (check the runout with an indicator).
3. Unbalanced wheels — after replacing the disks, it is recommended to do balancing.
4. Sticky caliper — disassemble and lubricate the guides.
If the vibration does not disappear, try swapping the disks (left to right). If the problem persists, it's the hub or suspension.
How to extend the life of brake discs
Average life of brake discs Nissan Almera Classic — 80,000–120,000 km, but with proper operation this figure can be increased by 30–40%. Here are the key recommendations:
- 🚦 Avoid "pedaling" — frequent short presses on the brake pedal in traffic jams lead to overheating. Better to use engine braking (downshifting).
- 💨 Don't keep your foot on the pedal — even light pressure when moving leads to microbraking and wear.
- 🚿 Wash your wheels in winter - salt and reagents corrode the metal. After driving through puddles of reagents, wash the discs with water (but do not pour it on hot brakes!).
- 🔧 Check the calipers — a jammed piston or guides accelerates disc wear by 2–3 times. Sign of a problem: One side of the disc wears faster than the other.
Also note brake fluid quality. If it is old (over 2 years) or has absorbed moisture, the boiling point decreases, which leads to “steaming” of the brakes and accelerated wear of the discs. For Almera Classic liquid recommended DOT-4 with a boiling point not lower 230°C.
The most common cause of premature disc wear on Almera Classic — jammed caliper guides. They need to be cleaned and lubricated every 20,000 km, even if the pads and discs are still normal.
Should I install perforated or grooved discs?
Many owners Almera Classic are considering installing perforated or notched discs to improve braking performance. However, for this car such modifications are often unjustified:
- ✅ Pros:
- Better cooling (relevant for racing tracks).
- Quick removal of gases and dust from the surface.
- Sporty appearance.
- ❌ Cons:
- Rapid pad wear (20–30% faster).
- Tendency to cracks during intensive use.
- High price (1.5–2 times more expensive than standard disks).
- Increased noise when braking.
For everyday driving Almera Classic remain the optimal choice standard ventilated discs from trusted brands (Brembo, TRW, Bosch). Perforated discs are only suitable if you:
- Drive regularly on serpentine or mountain roads.
- Participate in amateur races.
- You operate a vehicle with a trailer (weight > 1 t).
What to do if the disk fails after replacement
Deformation of a new disc (“driving”) is a common problem that manifests itself as a wobble in the steering wheel when braking. The reasons may be different:
| Reason | How to check | Solution |
|---|---|---|
| Incorrect tightening of hub bolts | Check the tightening torque with a torque wrench | Tighten the bolts crosswise with a force of 80–100 Nm |
| Disc defect (uneven thickness) | Measure the thickness at 4-6 points using a caliper | Replace the drive under warranty |
| Overheating during break-in | The beating appeared after hard braking | Allow the discs to cool down, avoid heavy braking for 300 km |
| Dirt between the disc and the hub | Remove the disc and inspect the mating surface | Clean the hub and disc, apply copper grease |
If the disk “leads” due to overheating, you can try turning it on a lathe. However, this is a temporary solution: after grooving, the thickness of the disc decreases and its service life is reduced. For Almera Classic maximum permissible groove - 0.5mm on each side.
⚠️ Attention: If the steering wheel wobbles when braking is accompanied by knocking in the suspension, the problem may not be in the disks, but in worn silent blocks or ball joints. Check these components before replacing drives!
FAQ: Frequently asked questions about brake discs Nissan Almera Classic
Can I install wheels from other Nissan models?
Theoretically on Almera Classic suitable for wheels from Nissan Primera P11 (front) and Nissan Sunny N16 (rear if they are disc). However, you need to check:
- Matching diameter and thickness.
- Type of fastening (number and location of holes).
- Caliper compatible (some discs may be wider or narrower).
It is better to use discs designed specifically for Almera Classicto avoid problems with braking performance.
How often should the thickness of the rims be checked?
Recommended inspection interval - every 20,000 km or every time you replace the pads. If you often drive on mountain roads or with a trailer, check the rims every 10,000 km. To measure, use a caliper or a special probe.
Which is better: original Nissan wheels or analogues?
Original wheels Nissan (article 40520-4M000 for the front ones) are manufactured by the company Sumitomo and are of high quality. However, their price is 1.5–2 times higher than their analogues. Alternative:
- TRW or Brembo — the quality is not inferior to the original, the price is 20–30% lower.
- Bosch — a good option for urban use.
- ABS or Nipparts - budget, but the resource is 15–20% less.
If your budget allows, choose TRW or Brembo — they are supplied to the assembly lines of many automakers.
Do I need to bleed the brakes after replacing the discs?
Bleeding the brakes is only required in two cases:
- If you have disconnected the brake hoses from the caliper.
- If after replacement the brake pedal becomes “soft” (a sign of air ingress).
If you simply removed the caliper without disconnecting the hoses, bleeding is not necessary. But check the brake fluid level in the reservoir - it could have dropped due to the displacement of the caliper piston.
Why do new wheels rust quickly?
Corrosion on new discs is normal if the car is not driven for more than 2-3 days. The cast iron from which the discs are made oxidizes in air. To slow down the process:
- Use discs with a protective coating (eg Bosch Protective Coating).
- After washing, dry the wheels with short stops.
- Store the car in a dry place (or use wheel covers).
Rust on the working surface of the disc is cleaned off after the first braking and does not affect efficiency.
