Rear brake discs <em>Nissan Almera N16</em>: how to select and replace correctly

Nissan Almera N16 is a popular sedan that is still found on the roads due to its reliability and ease of maintenance. However, even such time-tested models have weaknesses, and one of them is rear brake discs. Over time, they wear out, become deformed or become corroded, which directly affects the safety and comfort of driving.

In this article we will look at everything you need to know about rear brake discs. Almera N16: from signs of wear And diagnostics to selection of spare parts And step-by-step replacement. We will pay special attention unique nuances of this model, which are often overlooked even by experienced car owners. For example, why on Almera N16 With and without ABS, different wheels may be required, and how this affects the cost of repairs.

Signs of wear on the rear brake discs Nissan Almera N16

The first symptoms of brake disc problems are often ignored until the situation becomes critical. Here's what you should pay attention to:

• 🔊 Creaking or squealing when braking - most often caused thinning of the disc or sand getting between the block and the surface. On Almera N16 This sound can appear even with minimal wear due to the characteristics of the disc material.
• 🌀 Whirling steering wheel or brake pedal - signals about disc deformation (often after overheating or shock). This is less noticeable on the rear axle than at the front, but cannot be ignored.
• 🛑 Increased braking distance — if the pads are normal, the problem is in the discs. On Almera N16 With worn rear discs, the car may pull to the side when braking hard.
• 🔥 Overheating and burning smell - thin disks heat up faster, which leads to boiling brake fluid and loss of braking efficiency.

Feature Almera N16 — rear discs often "drive" due to corrosion, even if the thickness is normal. This is due to the design of the hub and insufficient ventilation. If you can see on the disk deep grooves or rust spots, it is better to replace it, even if the thickness is close to acceptable.

⚠️ Attention: On Almera N16 with ABS worn discs can cause false alarms of the system due to uneven rotation of the wheel. If the ABS light on the dash comes on for no apparent reason, check the rear discs first!

Technical characteristics and article numbers of rear discs for Nissan Almera N16

It's important to know them before purchasing new drives exact parameters. For Almera N16 (2000–2006) rear brake discs have the following characteristics:

Parameter	Meaning	Note
Diameter	232 mm	Same for all modifications
New disc thickness	10 mm	Minimum permissible - 8 mm
Mounting type	4 bolt	Thread M10×1.25
Material	Cast iron	Ventilated discs were not installed
Central hole	54.1 mm	Important for hub compatibility

Original wheels from Nissan have an article number 40520-4M000 (for models without ABS) and 40520-4M001 (with ABS). However, their cost is often overpriced (from 4,500 rubles per piece), so many choose analogues:

• 🔧 ATE — 24.0120-0156.1 (Germany, high quality, price ~3,200 rub.)
• 🔧 Brembo — 09.9363.11 (Italy, optimal price/quality balance, ~2,800 rub.)
• 🔧 TRW — DF4530 (UK, often counterfeit, check packaging!)
• 🔧 Febi — 22710 (Germany, budget option, ~2,100 rub.)

Important: Discs for Almera N16 with and without ABS interchangeable, but may differ in weight and balancing. If you have a model with ABS, it is better to choose wheels marked for ABS - this will reduce the risk of vibrations.

Diagnostics of rear brake discs: when is it time to change?

Check the condition of the rear discs Almera N16 recommended every 20–30 thousand km or when replacing pads. Here's how to do it yourself:

1. Visual inspection: Jack up the car and remove the wheel. Inspect the disk for cracks, deep grooves or rust. If the surface is uneven (can be checked with your finger), the disc must be replaced.
2. Thickness Measurement: Use a caliper. If the thickness is less 8 mm, the disk needs to be changed. On Almera N16 Uneven wear is common - measure at 3-4 points around the circumference.
3. Runout check: Put the wheel back on, lift the car and spin it. If the disc "beats", you will feel vibration in the suspension. Allowable runout - no more 0.15 mm.
4. Overheating test: After active braking (for example, on a descent), touch the disc with your hand (carefully!). If it burns, that's a sign jammed caliper or excessive wear.

Lifehack: On Almera N16 rear discs often “stick” to the hub due to corrosion. If the disc was not removed when replacing the pads, there is a high risk that it will have to be removed during the next repair. cut with a grinder. To avoid this, after installing new discs, apply to the adjacent surface of the hub. copper grease.

⚠️ Attention: If there is on disk deep circular grooves (from 1 mm or more), it cannot be sharpened! On Almera N16 this will lead to uneven braking and accelerated wear of new pads.

Step-by-step replacement of rear brake discs with Nissan Almera N16

Replacing rear discs with Almera N16 more difficult than the front ones, due to parking brake and less convenient access. Here are the detailed instructions:

Required tools:

• 🔧 Jack and stops
• 🔧 Key for 17 and 19 (for caliper)
• 🔧 Torx T40 (for some models)
• 🔧 Hammer and wooden block (for removing stuck disk)
• 🔧 Vernier calipers (to check the new disc)
• 🔧 Copper grease

Sequence of actions:

1. Removing the wheel and caliper:

   Raise the car, remove the wheel. Unscrew the two caliper mounting bolts (17 wrench) and hang it on a wire so as not to damage the hose. Do not disconnect the brake hose!

2. Removing the old disk:

   Unscrew the two guide pins (19 wrench or Torx T40). If the disc does not come off, gently tap the rim with a hammer through a block of wood. On Almera N16 you often have to use a puller or grinder due to corrosion.

3. Installing a new disk:

   Clean the hub from rust, apply a thin layer of copper grease to the adjacent surface. Install the new disc and secure with pins. Tighten them crosswise with force. 80–100 Nm.

4. Assembly and pumping:

   Reinstall the caliper, replace the pads (if necessary) and reassemble everything in reverse order. After replacement be sure to bleed the brakes, since when removing the caliper, air could get into the system.

Important! After replacing the disks with Almera N16 first 200–300 km Avoid sudden braking - the pads need to get used to it. Also check the brake fluid level and add if necessary.

Common mistakes when replacing rear discs with Almera N16

Even experienced craftsmen sometimes make mistakes that lead to premature wear or incorrect brake operation. Here are the most common:

• 🔧 Ignoring the parking brake: On Almera N16 The rear discs are integrated with the handbrake drum. If the cables are not adjusted after replacement, the handbrake will either be weak or jammed.
• 🔧 Incorrect tightening: Tightened pins lead to disc deformation, and a weak tightening leads to its beating. Use a torque wrench!
• 🔧 Savings on pads: Installing new discs with old pads will accelerate wear on both parts. The pads must be not more worn out than 50%.
• 🔧 Lack of lubrication: Without copper grease on the hub, the disc may “stick” within a year, and it will be difficult to remove it.

Hidden problem: On some Almera N16 (especially after 2003) the rear hubs have thread defect under the disc pins. If, when tightening, you feel that the threads are “breaking”, do not continue - replace the hub or cut a new thread.

⚠️ Attention: If, after replacing the disks, squeaking noise when braking, this is not always a defect in parts. On Almera N16 often helps applying anti-squeak paste on the back of the pads (for example, ATE Plastilube).

What to do if the new disk fails?

If you feel a beating after installing a new disk, the reasons may be as follows:

1. **Balancing Incorrect** - Check that the pins are evenly tightened.

2. **Deformed hub** - measure the hub runout with an indicator (tolerance - 0.05 mm).

3. **Defective disk** - even new disks can be crooked (check on a bench).

4. **Incorrect installation** - if the disk is warped when tightening, it must be removed and reinstalled.

In 80% of cases, the problem is solved by reinstalling the disk while observing the tightening torque.

Cost of replacing rear brake discs: prices and where is cheaper

Cost of replacing rear discs Nissan Almera N16 depends on several factors: region, type of service station and selected spare parts. Here are the estimated prices for 2026:

Service/Part	Cost (RUB)	Note
Disc (1 pc., analogue)	2 000–3 500	ATE/Brembo is more expensive, Febi/Delphi is cheaper
Pads (rear set)	1 500–2 500	It is recommended to change along with the disks
Work (replacing 2 discs + pads)	3 000–5 000	Includes brake bleeding
Disc groove (1 pc.)	800–1 200	Only if the thickness allows
Handbrake adjustment	500–1 000	Often required after replacement

Where is it cheaper to change:

• 🔧 "Sharashka" garages — from 2,500 rub. for work, but the risk of running into amateurs.
• 🔧 Specialized brake centers — 3,500–4,500 rubles, but with a guarantee of work.
• 🔧 Official services - from 6,000 rubles, but they use original spare parts.
• 🔧 Self-replacement - only if you have experience and tools (save 3,000–5,000 rubles).

Advice: If your budget is limited, you can save on pads - buy NISSAN D1060-JD00A (original) or Bosch 0 986 494 219 (analog). But you shouldn’t skimp on disks - cheap ones often come with uneven thickness, which will lead to beating.

Alternative solutions: groove vs. replacement

If the discs are worn uncritically (thickness > 8.5 mm), they can be sharpen instead of replacement. It's cheaper, but not always suitable. Let's look at the pros and cons:

Criterion	Groove	Replacement
Cost	800–1,200 rub. per disc	2,000–3,500 rub. per disc
Service life	10–20 thousand km	50–80 thousand km
Braking quality	May deteriorate due to decreased thickness	Recovers up to 100%
Risk of runout	High if the disc is already deformed	Minimum

The groove is justified in two cases:

1. The disc is new, but caused by overheating (for example, after a long descent from the mountain).
2. Disc thickness 9–9.5 mm, and you are planning to sell your car soon.

When the groove is useless:

• 🚫 Disc thickness is smaller 8.5 mm.
• 🚫 On the surface there is deep cracks or chips.
• 🚫 Disk corroded from the inside (common problem Almera N16).

Lifehack: If you decide to sharpen the wheels, be sure to check wheel bearing condition. On Almera N16 a worn bearing can produce the same runout as a crooked disc. Replacing it will cost 1,500–2,000 rubles. per side.

FAQ: Frequently asked questions about rear brake discs Nissan Almera N16

Is it possible to install ventilated discs instead of standard ones?

No, it's pointless. Rear discs on Almera N16 are not loaded as much as the front ones, so ventilated ones will not give a noticeable effect. In addition, they are heavier, which will increase unsprung mass and will reduce comfort.

How long do rear discs last? Almera N16?

The service life depends on the driving style and the quality of the pads:

• 🚗 When driving quietly - 80–120 thousand km.
• 🏁 During aggressive driving - 40–60 thousand km.
• ❄️ In conditions of frequent driving through salt/reagents - 30–50 thousand km (due to corrosion).

Do I need to change the pads along with the discs?

Yes, necessarily. New discs with worn pads will grind unevenly, which will lead to:

• 🔹 Accelerated wear of discs.
• 🔹 Vibrations when braking.
• 🔹 Possible caliper jamming due to uneven pressure.

The exception is if the pads are almost new (wear < 30%).

Why do brakes squeak after replacing discs?

Creaking can occur for several reasons:

• 🔧 Low quality pads — cheap friction materials often creak.
• 🔧 No anti-squeak paste - Apply it to the back of the pads.
• 🔧 Unpolished surfaces — the squeak should disappear after 200–300 km.
• 🔧 Dirt entry between the pad and the disc - wash the brakes Brake Cleaner.

Is it possible to drive if the disc is thinner than 8 mm?

Highly not recommended. With thickness less than 8 mm disk:

• 🔥 Overheats faster, which leads to boiling brake fluid.
• 💥 Maybe crack during sudden braking.
• 🚗 Increases braking distance by 20–30%.

If the disc is worn to 7.5 mm or less, operating the machine is dangerous.
