Nissan Primera P12 - a legendary sedan that is still popular due to its reliability and unpretentiousness. But even such a time-tested car has components that require regular attention. One of them is braking system, and specifically the pads. Not only driving comfort, but also safety on the road depends on their condition.

In this article we will look at everything you need to know about brake pads for Primera P12: how to determine wear, what original and non-original options exist, how to replace it yourself and what to look for when choosing. And we’ll also reveal unique nuances of this model that even experienced car owners often miss.

Signs of brake pad wear on Nissan Primera P12

The first signs that your brake pads need replacing are often ignored until the brakes start squeaking or, worse, squeaking. But on Primera P12 There are also less obvious signs that are worth knowing:

  • 🔊 Creaking or whistling when braking - a classic signal that the friction layer has been worn down to metal. On P12 This sound is especially noticeable when you lightly press the pedal.
  • 📉 Increased braking distance. If the car slows down worse and the pedal “sinks” deeper than usual, this is a reason to check the thickness of the pads.
  • 🚗 Vibration or beat on the steering wheel when braking. Often indicates uneven pad wear or deformation of brake discs (relevant for Primera P12 with a mileage of 150 thousand km).
  • 💨 Dust on wheels. Abundant black deposits are the norm for new pads, but if there is noticeably more dust, this may indicate accelerated wear.

On Nissan Primera P12 (especially with engines QR20DE And QR25DE) there is one peculiarity: the front pads wear out 2-3 times faster than the rear ones due to the distribution of braking forces. Therefore, you need to check their condition every 20–25 thousand km, even if there are no obvious signs of malfunction.

⚠️ Attention! If the indicator on the dashboard comes on ABS or BRAKE, this may be due not only to the pads, but also to the sensors or brake fluid level. On P12 Such errors often occur when the rear pads are critically worn, since sensors of minimum thickness are installed there.

Original and similar brake pads: what to choose?

Factory pads for Nissan Primera P12 are produced under the brand Nissan (article 40520-4M000 for front and 40520-4M001 for the rear). They guarantee perfect compatibility, but their price is often steep - from 4 to 6 thousand rubles per set. An alternative is analogues from trusted brands:

Brand Article (front) Article (rear) Average price, ₽ Features
ATE 13.0460-7106.2 13.0460-7166.2 3 200–3 800 Soft friction material, produces little dust, but wears out faster
Brembo P 58 030 P 58 031 3 500–4 200 High wear resistance, but may creak during the first 500 km
TRW GDB1446 GDB1447 2 800–3 400 Optimal price/quality ratio, suitable for aggressive driving style
Ferodo FDB1446 FDB1447 3 000–3 600 Low noise level, but require running-in (first 300 km)

When choosing analogues, pay attention to friction material composition:

  • 🔹 Semi-metallic - durable, but noisy and aggressive towards discs (suitable for a sporty driving style).
  • 🔹 Ceramic - quiet, generates little dust, but more expensive and less effective at low temperatures.
  • 🔹 Organic — soft, discs are gentle, but wear out faster (optimal for city driving).
⚠️ Attention! On Primera P12 with the system ESP (electronic stability control) it is not recommended to install pads with a coefficient of friction lower 0.35. This may lead to system malfunctions!

Step-by-step instructions for replacing brake pads Nissan Primera P12

Replacing the pads with P12 does not require special equipment, but there are nuances that will simplify the process. You will need:

  • 🔧 A set of socket wrenches (especially for 12 And 14).
  • 🔨 Hammer and screwdriver with a flat blade (for squeezing out the caliper piston).
  • 🧴Brake fluid DOT-4 (in case of pumping).
  • 🛠️ Lubricant for caliper guides (for example, Slipkote 220-R DBC).
  • 🧤 Gloves and protective equipment (brake dust is harmful to health!).

Before starting work, be sure to:

Loosen the wheel bolts (but do not remove the wheel!) | Jack up the car and jack up the rear wheels | Remove the brake fluid reservoir cap (to reduce pressure in the system) | Clean the caliper and guides of dirt (use a wire brush)-->

Step 1: Removing the old kit

Unscrew the two caliper mounting bolts (usually on 14) and carefully hang it on a wire so as not to damage the brake hose. Remove the old pads - they can “stick” to the guides, so sometimes a light tap with a hammer is required.

Step 2. Inspect the brake disc

On Primera P12 common collar at the edge of the disc (due to wear). If its height exceeds 1 mm, the disc needs to be sharpened or replaced. Also check for cracks or deep grooves - this is a sign of critical wear.

Step 3. Installing new pads

Before installation, apply a thin layer of lubricant to caliper guides And the back of the pads (but not on the friction layer!). Install the pads in reverse order, then return the caliper to its place. Important: on P12 the front pads have asymmetrical shape - do not confuse left and right!

Step 4. Running in

After replacement, avoid sudden braking for the first time. 200–300 km. This is necessary for uniform grinding of the pads to the disc. Also check the brake fluid level - it may drop due to shrinkage of the caliper piston.

💡

If the brake pedal becomes soft after replacing the pads, bleed the system. On Primera P12 you can do this yourself using a syringe and tube, but it is more convenient to use a vacuum pump.

Common mistakes when replacing pads Nissan Primera P12

Even experienced car owners sometimes make mistakes that lead to squeaking, uneven wear, or even brake failure. Here's what not to do:

  • 🚫 Ignore the condition of the caliper guides. If they are acidified or corroded, the pads will jam, which will lead to overheating and accelerated wear.
  • 🚫 Do not lubricate the back of the pads. This causes squeaks and vibrations when braking.
  • 🚫 Install pads without cleaning the caliper. Dirt and rust can get between the pad and piston, causing an incomplete seal.
  • 🚫 Forget about the rear pads. On P12 they wear out more slowly, but their service life is also not eternal - check every 40–50 thousand km.

Another typical problem is incorrect running-in. Many people test the brakes immediately after replacing them by pressing the pedal sharply, which leads to overheating and deformation of the friction layer. First 100 km Brake smoothly, without jerking.

⚠️ Attention! If, after replacing the pads, the car pulls to the side when braking, most likely the caliper is stuck or the pads are installed incorrectly. On Primera P12 this may also be due to wear on the wheel bearing - check its play!

The service life of the pads: what does it depend on and how to extend it?

Brake pad life Nissan Primera P12 varies from 30 to 80 thousand km, depending on several factors:

  • 🚗 Driving style. Aggressive acceleration and sharp braking reduce the service life by 2–3 times.
  • 🏙️ Operating conditions. In the city (frequent stops) the pads wear out faster than on the highway.
  • 🌡️ Quality of materials. Cheap pads with a high metal content wear out faster and damage the discs.
  • 🔧 Brake system condition. Wedged calipers or worn guides will accelerate wear.

To extend the life of your pads:

  1. Clean the calipers and guides regularly from dirt (once every 10 thousand km).
  2. Use high quality brake fluid (eg Castrol DOT-4) and change it every 2 years.
  3. Avoid prolonged braking “for wear” (for example, when descending a mountain - it is better to use engine braking).
  4. Check the wheel balance. Imbalance leads to uneven wear of pads and discs.
Why on Primera P12 Do the front pads wear out faster?

On this model, the distribution of braking forces is shifted forward (about 70% of the load falls on the front axle). In addition, the weight of the engine (especially in versions with QR25DE) places additional load on the front brakes. Therefore, they are checked 2 times more often than the rear ones.

When do you need to replace brake discs?

Pads and discs are “consumables” that work in pairs. On Nissan Primera P12 Disk replacement is required when the following symptoms occur:

  • 📏 Disc thickness less than the permissible minimum (for front - 22 mm, for the rear - 9 mm).
  • 🌀 Deep grooves or cracks (more 0.5 mm).
  • 🔄 Steering wheel beating when braking (indicates disc deformation).
  • 🔥 Blue surface - a sign of overheating (often found when driving along mountain serpentines).

Original wheels for P12 have articles:

  • Front: 40500-4M000 (ventilated, diameter 280 mm).
  • Rear: 40530-4M000 (solid, diameter 260 mm).

When replacing discs, be sure to change the pads as well - the old ones will not provide a tight fit to the new surface. It is also recommended to sharpen the discs on a machine if their thickness is close to the minimum, but has not yet reached a critical value.

💡

On Primera P12 With a mileage of more than 200 thousand km, not only the discs, but also the wheel bearings often wear out. They are checked for play before replacing brake components.

FAQ: Frequently asked questions about brake pads Nissan Primera P12

Is it possible to install pads on only one axle (for example, only the front ones)?

No! Pads are always changed in pairs on the same axis (left + right). Replacing only the front or only the rear will result in uneven braking and increase the risk of skidding. The exception is if the pads on one side wear out prematurely due to a caliper malfunction (in this case, the cause is eliminated first).

How much do original pads cost and where is the best place to buy them?

Original set of front pads (40520-4M000) costs about 4 500–5 000 ₽, rear (40520-4M001) — 3 800–4 200 ₽. It is better to buy from official dealers Nissan or in trusted online stores (for example, Exist.ru, Autodoc). Beware of fakes - original pads have a hologram and markings NISSAN Genuine Parts.

Why do new pads squeak the first days after replacement?

It's normal! The creaking occurs due to rubbing in friction material to disk. It usually disappears after 200–500 km. If the squeak does not disappear, check:

  • The quality of the pads (cheap analogues often squeak all the time).
  • Availability of lubricant on the caliper guides.
  • Condition of the brake discs (grooves or rust may cause unusual sounds).

How often should brake pads be checked? Primera P12?

Recommended interval - every 20–25 thousand km or once a year (whichever comes first). It is also worth checking:

  • After long off-road trips (sand and dirt accelerate wear).
  • When vibrations or squeaks occur.
  • Before seasonal tire replacement.

On P12 with mileage for 150 thousand km It is better to check more often - every 15 thousand km.

Is it possible to sharpen brake discs yourself without removing them?

Technically possible, but not recommended. Grooving without removal (for example, using a tool on the hub) does not guarantee uniform metal removal and may worsen runout. On Primera P12 It’s better to remove the discs and grind them on a machine, checking the thickness with a micrometer. If the disk is thinner 22 mm (before) or 9 mm (rear), it needs to be replaced.
