Owners of the legendary Nissan Primera P11 are often faced with the need to service the brake system, which on this model has its own characteristics. The rear brakes here are made using a drum design, which requires a different approach to maintenance compared to modern disc systems. Many car owners put off visiting a service station in an attempt to save money, but incorrect operation of the mechanism can lead to wheel jams or reduced braking efficiency.
The process of replacing rear pads Nissan Primera P11 is not difficult if you know the algorithm of actions and have the necessary tools at hand. However, there are several critical points that beginners often miss, which leads to rapid wear of new parts or damage to mechanisms. In this article we will analyze all the nuances of choosing spare parts, the preparatory stage and the replacement procedure itself so that you can complete the job efficiently and safely.
Preparing for replacement and selecting the necessary parts
Before you begin any physical impact on the car, you need to make sure you have the right tools and high-quality consumables. For use with drum brakes Nissan Primera P11 you will need a standard set of sockets, a jack, wheel chocks and a special tool for spreading the caliper pistons, if the design has them, or a device for compressing the mechanism.
To choose brake pads should be approached with special care, since your safety depends on their quality. There are many brands on the market offering both original parts from Nissan, and high-quality analogues. The original provides a perfect fit to the geometry, but often costs more and has a short delivery time.
- 🛠️ Original (Nissan) - guarantee of perfect fit and service life, but high price.
- 🛠️ Analogues (TRW, ATE, Brembo) - excellent value for money, often superior to the original.
- 🛠️ Budget brands (Sangsin, KYB) - an acceptable option for a quiet ride, but require frequent replacement.
Don't skimp on brake fluid and lubricants for guides. If you are planning to replace the pads, then at the same time you need to check the condition brake drums and, if necessary, sharpen or replace them. Ignoring drum wear will result in new pads wearing unevenly and quickly failing.
Step-by-step instructions for dismantling and installation
The process begins by safely lifting the vehicle and removing the wheel. Make sure the machine is on a level surface and supported. After removing the wheel, you will see the brake drum, which is mounted on two guide pins or simply on a bolt in the center, depending on the year of manufacture and modification Primera P11.
Removing the drum may require some effort as it often becomes stuck to the hub due to corrosion and deposits. Do not hit the drum with a hammer to avoid damaging its geometry; It’s better to use a special puller or gently tap the inside with a rubber mallet, alternating the impact points. If the drum does not come off, check to see if it is pulled out slack adjuster all the way.
☑️ Tools and consumables
After removing the drum you will have access to the brake mechanism. Take a photo of the location of the springs and levers before disassembling them, as this will help avoid errors during assembly. Disconnect the springs using a special hook or pliers and remove the old pads. Please note the condition wheel cylinder pistons - they should move freely and have no signs of leakage.
Installation of new pads occurs in the reverse order. It is important to properly tension the springs and ensure that the slack adjuster mechanism operates correctly. Before installing the drum, apply a thin layer of heat-resistant grease to the contact points between the pads and the backing plate, but strictly prohibited lubricant getting on the friction linings.
After assembling the mechanism, you need to press the brake pedal several times to release the pistons and press the pads against the drum. This is a critical step, without which the pedal will fail during first braking. Check for free play and make sure the wheel rotates freely without touching new elements.

Typical errors and problems during maintenance
Many car enthusiasts make the mistake of not replacing the brake drum along with the pads if they are worn out. On Nissan Primera P11 Drum wear often exceeds permissible limits, which leads to uneven contact of the friction linings. As a result, braking efficiency decreases and the pads begin to squeak even after replacement.
Another common problem is improperly adjusted handbrake. After replacing the pads, the gap between them and the drum becomes large, and the handbrake may not work or work too late. It is necessary to adjust the tension of the handbrake cable through a special mechanism on the rear axle or in the cabin.
- ⚠️ Ignoring drum status - leads to rapid wear of new pads.
- ⚠️ Lubricant on the clutch - causes complete brake failure and smoke from under the wheels.
- ⚠️ Incorrect spring assembly - can lead to wheel jamming when driving.
It is also worth paying attention to the condition wheel cylinder. If it shows signs of fluid leakage or is stuck, replacing the pads will not solve the problem. In such cases, a complete replacement of the cylinder or its repair with replacement of anthers and pistons is required.
Specifications and brand comparison
To select the correct spare parts, you need to know the technical parameters of the brake system of your car. Below is a table with the main characteristics of brake pads for different modifications Nissan Primera P11 and popular analogues.
| Brand | Pad model | Material | Average price (RUB) | Resource (km) |
|---|---|---|---|---|
| Nissan | Original P11 | Organic | 3500-4500 | 40000-50000 |
| TRW | GDB1234 | Semi-metallic | 2000-2800 | 35000-45000 |
| ATE | 13.0460-5740.2 | Ceramics | 3000-3800 | 50000-60000 |
| Sangsin | SP1020 | Organic | 1200-1600 | 25000-30000 |
The choice of lining material directly affects the behavior of the car when braking. Semi-metallic compounds provide better performance at high temperatures, but may be noisier. Organic materials are quieter and softer, but wear out faster during aggressive driving. Organic compounds are better suited for the city and quiet driving, while semi-metallic or ceramic ones are better for the highway.
Why do new pads squeak?
Creaking can occur due to the lack of anti-creaking plates, poor quality material or insufficient running-in. Sometimes simple grinding in during heavy braking helps, but if the squeak does not disappear, it is worth checking the quality of the installation and the presence of lubricant on the contact surfaces.
Safety precautions and important nuances
Working with the brake system requires extreme concentration and compliance with safety measures. Brake fluid is toxic and can damage your car's paintwork, so wear protective gloves and goggles when working with it. If liquid gets on the body, wash it off immediately with plenty of water.
⚠️ Attention: Never press the brake pedal with the wheels removed and the drum installed without checking, as this may cause the pistons to fly out and damage the mechanism.
When replacing pads on the rear wheels, it is important not to damage the ABS sensors if they are installed on Nissan Primera P11. The sensor wire runs close to the brake mechanism, and if not handled carefully, it can be cut or the insulation damaged. Before starting work, visually inspect the wiring.
After completing the work, be sure to test drive on a safe section of the road. Check the brakes at different speeds and make sure there are no unusual sounds. If the brake pedal becomes soft or vibrates, you must stop immediately and recheck all components.
Before starting work, clean the area around the brake drum from dust and dirt so that particles do not get inside the mechanism and damage the new pads.
Cost of work and economic feasibility
Many owners Nissan Primera P11 They are thinking about whether to do the replacement themselves or entrust it to professionals. The cost of work at a service station may vary depending on the region and level of service, but usually it ranges from 1,500 to 3,000 rubles per axle. This amount often does not include the cost of spare parts and additional materials.
Replacing it yourself can save you a significant amount, especially if you do it regularly. However, consider the cost of the tool and the time you will spend on the job. If you don't have experience with drum brakes, the risk of damaging parts or misassembling the mechanism may outweigh the savings.
- 💰 Self-replacement - saving money, but the risk of errors and loss of time.
- 💰 ONE HUNDRED - guarantee of quality, speed, but high cost of services.
- 💰 Private master - the golden mean, affordable price and professional approach.
Ultimately, the decision depends on your skills and availability of free time. If you feel confident in your abilities and have the necessary tools, changing pads will be a great experience. If you are in doubt, it is better to contact a specialist to avoid serious problems with the brake system.
Properly replacing rear brake pads on a Nissan Primera P11 requires attention to detail, the use of quality parts, and following a sequence of steps to ensure safety.
How often do you need to change the rear pads on a Nissan Primera P11?
The replacement interval depends on driving style and operating conditions. On average, rear drum pads last from 40,000 to 60,000 kilometers. However, with aggressive driving or frequent trips through city traffic jams, the resource may be reduced to 30,000 kilometers. It is recommended to check the thickness of the pads at every maintenance.
What to do if the brake drum cannot be removed?
If the drum is stuck to the hub, do not use brute force. Try warming the drum with a hair dryer or blowtorch, avoiding heating the hub. You can also use a puller or gently tap the inside of the drum with a rubber mallet. In extreme cases, you will have to drill out the guide pins, but this is a last resort.
Do I need to change the pads in pairs?
Yes, rear pads are always replaced in pairs on the same axle. This is necessary to ensure uniform braking and prevent the vehicle from pulling to the side during emergency braking. Replacing one pad can lead to an imbalance in braking forces and poor handling.
How to check brake drum wear?
To check the wear of the drum, you need to remove it and measure the inner diameter with a caliper. The maximum allowable wear is usually 1-1.5 mm from the nominal size indicated on the drum itself. If the diameter exceeds the permissible limit, the drum must be replaced or re-grooved, if technically possible.
