Nissan Almera G15 is a popular sedan, but its brake system requires regular maintenance. One of the key elements is the caliper, which wears out over time. If you notice squeaking, sticking, or uneven wear on your pads, it's likely time to replace the repair kit. In this article we will look at how to choose high-quality spare parts, avoid mistakes when replacing and extend the service life of the brakes.
Many car owners are faced with a dilemma: should they buy an original repair kit or analogues from trusted brands? We analyzed the market, studied reviews and prepared a checklist of selection criteria. You will also find step-by-step instructions with photos, typical beginner mistakes and answers to frequently asked questions. Don't miss out unique information on the compatibility of repair kits with different years of manufacture Almera G15 - this will save you time and money.
Signs of caliper wear: when to replace the repair kit
Caliper Nissan Almera G15 does not have strict replacement regulations - it all depends on driving style and operating conditions. However, there are obvious symptoms that indicate the need for repair:
- π Creaking or whistling when braking - often caused by worn guides or piston.
- π Uneven pad wear (one side wears out faster) is a sign of a jammed caliper.
- π¨ Brake disc overheating after a trip (the disc is hot, but the wheel is not) - this indicates a soured piston.
- π Increased brake pedal travel - may indicate a brake fluid leak through the cuffs.
If you ignore these signs, the consequences can be serious: from premature wear of the brake discs to complete brake failure. For example, a stuck caliper at a speed of 80 km/h increases the braking distance by 30β40%!
- Every 10,000 km
- Once a year
- Only when problems arise
- Never checked
Particular attention should be paid guide boots. On Almera G15 They often break due to dirt, which leads to corrosion of the fingers. You can check their condition visually - just remove the wheel and inspect the caliper for cracks or lubricant leaks.
Which repair kits are suitable for Nissan Almera G15: original vs analogues
There are three types of caliper repair kits on the market Almera G15 (2012β2019): original, non-original premium-class and budget analogues. Let's look at the pros and cons of each option.
| Type of repair kit | Article (front/rear) | Average price, β½ | Pros | Cons |
|---|---|---|---|---|
| Original (Nissan) | 40520-4M000 / 40520-4M010 |
3 500β4 200 | 100% compatible, long service life | High price, risk of running into a fake |
| Premium analogues | ATE 03.9902-7806.2 / TRW GDB1446 |
2 200β3 000 | Quality is not inferior to the original, wide availability | There are defective lots |
| Budget analogues | Fenox SB10012O7 / LPR 05P0144 |
800β1 500 | Low price, fast delivery | Service life is 2β3 times less than the original |
An important nuance: repair kits for Almera G15 before and after 2016 may differ! For example, the 2017+ model calipers used reinforced piston boots. Check the VIN of your car before purchasing.
β οΈ Attention: Some sellers issue repair kits from Nissan Note or Micra for compatible with Almera G15. This is not always the case - check the article numbers in the catalogue!
If you choose analogues, give preference to brands ATE, TRW or Brembo. They supply components to the assembly lines of many automakers, including Nissan. From the budget options it is better to take Fenox β although their rubber quality is not ideal, the geometry of the parts is precisely maintained.
Step-by-step instructions for replacing the caliper repair kit
Replacing the repair kit with Nissan Almera G15 does not require special tools, but will require care. Here's what you'll need:
- π§ Set of sockets and keys (12, 14, 17 mm)
- π§΄ Lubricant for guides (SLIPKOTE 220-R DBC or analogues)
- π§ΌBrake fluid
DOT-4(at least 250 ml) - π§€ Rubber gloves and rags
- π¨ Clamp for pressing the piston
Before starting work necessarily remove the negative terminal from the battery - this will prevent accidental operation of the electronics. Also prepare a container for draining the brake fluid.
Loosen the wheel bolts|Raise the car on a jack and install jack stands|Remove the wheel and clean the caliper from dirt|Pump out the brake fluid from the reservoir (to the MIN level)|Place a rag under the caliper to collect spilled fluid-->
Step 1. Removing the caliper
Unscrew the two bolts securing the caliper to the bracket (usually 14 mm). Carefully remove the caliper and hang it on a wire - don't let it hang on the brake hose! Next, remove the brake pads and inspect the disc for damage.
Step 2. Disassembly and replacement of parts
Remove the piston boot, then carefully press out the piston with compressed air (or a clamp). Carefully inspect the cylinder mirror - if there is scoring or corrosion, the entire caliper must be replaced. Install new cuffs and boots from the repair kit, having previously lubricated them DOT-4.
What to do if the piston does not come out?
If the piston is stuck, try the following methods:
1. Apply air pressure through the bleeder hole.
2. Gently tap the caliper with a wooden block.
3. Fill the cylinder with liquid WD-40 and leave for 10-15 minutes.
If all else fails, the caliper must be replaced.
Step 3. Assembly and pumping
Reassemble the caliper in reverse order, install new pads and put everything back in place. After assembly be sure to bleed the brakes, since air may have entered the system. On Almera G15 It is convenient to start pumping from the rear right wheel.
β οΈ Attention: After replacing the repair kit, avoid sharp braking for the first 200β300 km - the new cuffs should βget inβ. Also check the brake fluid level after 1,000 km.
Typical mistakes when replacing a repair kit and how to avoid them
Even experienced car owners sometimes make mistakes that lead to repeated repairs. Here are the most common of them:
- Using the wrong lubricant. Do not use under any circumstances
LitolorSolid oilfor guides - they destroy the rubber of the anthers. Only specialized lubricants based on synthetic rubber. - Bolt tightening. Caliper mounting bolts are tightened with force
25β30 Nm. Exceeding the torque leads to deformation of the bracket. - Ignoring the condition of the brake discs. If the disc has a shoulder of more than 1 mm or cracks, it must be sharpened or replaced. Otherwise, the new pads will wear unevenly.
- Incomplete bleeding of brakes. Air in the system may remain in GTZ (brake master cylinder). Pump until liquid comes out of the fitting without bubbles.
Another common problem is incorrect installation of the piston boot. It must sit without distortion, otherwise it will tear at the first braking. Before installation, lubricate the inside of the boot with a thin layer DOT-4.
Before assembling the caliper, apply a thin layer of copper grease to the guides - this will prevent them from sticking and make the next repair easier.
If after replacing the repair kit the brake pedal becomes βsoftβ, check:
- π§ Tightness of connections (are there any liquid leaks).
- π Correct pumping (there may be some air left).
- π Condition of the brake hoses (they could crack over time).
Comparison of repair kits for front and rear calipers
The design of the front and rear calipers Nissan Almera G15 is different, therefore the repair kits are not interchangeable. Let's look at the key differences:
| Parameter | Front caliper | Rear caliper |
|---|---|---|
| Construction type | Floating bracket | Floating caliper with integrated parking brake |
| Number of pistons | 1 | 1 (but with handbrake mechanism) |
| Repair kit article number | 40520-4M000 (original) |
40520-4M010 (original) |
| Common problems | Worn guides, leaking piston cuffs | Handbrake mechanism jammed, piston corrosion |
Rear calipers Almera G15 more capricious due to the integrated parking brake mechanism. When replacing a repair kit you need:
- Check the condition of the handbrake cable (it often turns sour).
- Lubricate the threads of the adjusting mechanism.
- Adjust the gap between the pads and the disc after assembly.
If after replacing the rear repair kit the handbrake does not hold, most likely the problem is a stretched cable or incorrect adjustment. On Almera G15 The handbrake is adjusted with a nut under a plastic plug in the cabin (next to the lever).
How to extend the service life of the caliper after replacing the repair kit
To make your new repair kit last longer, follow these recommendations:
- πΏ Wash the calipers every 10,000 km (without using aggressive chemicals).
- π’ Change the brake fluid once every 2 years - it is hygroscopic and corrodes the cuffs over time.
- π§ Check the play of the guides every time you replace the pads.
- π‘ Avoid overheating your brakes (for example, prolonged braking on a descent).
Pay special attention winter operation. After driving through slush or chemicals, wash the calipers with water (when they have cooled down!). Salt and sand quickly destroy the anthers.
Regular lubrication of the guides (every 20,000 km) reduces wear on the repair kit by 40% and prevents squeaking when braking.
If you often drive off-road, install protective shields on the calipers. They prevent dirt and stones from entering. For Almera G15 fit shields from Nissan Juke (article 40530-4M000) - they are identical in fastenings.
Where to buy a caliper repair kit for Nissan Almera G15: verified suppliers
Not only the price, but also the originality of the parts depends on the place of purchase. Here are reliable options:
- π¬ Official Nissan dealers - guarantee of original spare parts, but prices are 20β30% higher than the market.
- π Online stores:
- Exist.ru β a wide range of analogues, convenient selection by VIN.
- Autodoc.ru β frequent discounts, but sometimes long delivery.
- Emex.ru β specialize in brake systems, there are rare items.
- π Local showdowns β you can find used calipers in good condition (price from 1,500 β½), but there is a risk of running into worn parts.

β οΈ Attention: There are many fake repair kits on the market ATE And TRW. Original parts from these brands always have their logo laser engraved on the metal parts.
If you buy a repair kit for the rear caliper, check whether it is included parking brake rubber. In some sets (for example, Fenox SB10013O7) it is not there - you will have to buy it separately.
FAQ: Frequently asked questions about caliper repair kits Nissan Almera G15
Is it possible to replace only the boots without touching the cuffs?
Technically possible, but not recommended. Over time, the cuffs become tanned and lose elasticity. If you replace only the boots, the risk of brake fluid leakage remains. It is better to change the entire repair kit.
How much does it cost to replace a repair kit at a service center?
The cost of work depends on the region:
- Front caliper: RUB 1,500β2,500 per side.
- Rear caliper: 2,000β3,000 β½ (due to difficulty with the handbrake).
If you change it yourself, you save up to 70% of the cost.
How often should the repair kit be changed?
Service life depends on operating conditions:
- Urban mode: 60,000β80,000 km.
- Aggressive driving/off-road: 40,000β50,000 km.
We recommend inspecting the calipers every 20,000 km.
What happens if you donβt change the repair kit?
The consequences range from increased pad wear to complete brake failure. For example:
- Jammed piston β disc overheating and deformation.
- Torn boot β corrosion of guides and souring of the caliper.
- Cuff leak β drop in brake fluid level and brake failure.
Is the repair kit suitable for Nissan Note on Almera G15?
Partially. Front calipers Note (2012β2016) identical Almera G15, but the rear ones are different due to a different handbrake mechanism. Always check catalogs for VIN.
