Crossover operation Nissan Qashqai the second generation, known in the J11 body, requires close attention to the safety system, especially to the brake circuit. The rear brake discs on this model perform a critical function in keeping the vehicle stable when decelerating and preventing skidding when cornering. Unlike the front wheels, the rear axle experiences less load, however, the specific design of the J11 dictates its own maintenance rules.
Many owners mistakenly believe that replacing rear discs is a simple formality that can be put off for a long time. In fact, ignoring brake wear on the rear axle can lead to serious problems with electronic stability control and ABS systems, which actively use sensor data to control the distribution of braking forces. High quality brake discs - these are not just metal circles, but a complex engineering structure on which the safety of passengers depends.
Owners Nissan Qashqai It is necessary to regularly check the condition of the brake system, since even minor deformations can cause vibration of the steering wheel and reduced braking efficiency. In this article we will analyze in detail the design features, criteria for selecting spare parts and the nuances of self-replacement so that you can extend the life of your car.
Design features and disk sizes for J11
Since 2014, model Nissan Qashqai The J11 received an updated platform, which entailed changes in the braking system compared to its predecessor, the J10. The rear brakes on most trim levels are disc, which is a huge plus for safety and ease of maintenance, as opposed to drum mechanisms often found on budget segments.
The standard sizes of rear discs for this model are strictly regulated by the manufacturer. Usually we are talking about a diameter of **296 mm** and a thickness of **10 mm** (minimum permissible), while the new part has a thickness of **12 mm**. It is important to understand that using incorrectly sized discs may interfere with the operation of the electronic handbrake and wear sensors.
A design feature is the presence of perforation or ventilation, which depends on the type of engine and vehicle equipment. For diesel versions and powerful gasoline units, ventilated discs are often installed that can remove heat more efficiently. Ventilated design provides better heat transfer during intense braking, preventing overheating of the brake pads.
It is also worth paying attention to the seat and the number of mounting holes. U Nissan Qashqai J11 is a standard 5x114.3 bolt pattern, but the center hole and profile of the hub must match the original parameters perfectly, otherwise the disc will have runout, which will cause the brake pedal to run out.
Please note that for versions with all-wheel drive (4x4), the parameters of the rear drives may differ slightly due to the presence of additional drive elements, although in most cases they are unified with front-wheel drive versions.
Signs of wear and need for replacement
You can determine the need to replace the rear brake discs both visually and by indirect signs in the car’s behavior. The first and most obvious signal is the appearance of vibration or beating in the brake pedal when pressed, which often indicates disc deformation (increased runout) or uneven wear.
A visual inspection requires removing the wheel and carefully examining the surface. If you see deep scratches, grooves or cracks, the use of such parts is unacceptable. Also a critical factor is the thickness of the disk: if it has reached the minimum permissible value indicated on the disk itself or in the technical documentation, the part must be immediately replaced.
An indirect sign of wear is a change in the nature of braking: the car may begin to pull to the side, or the pedal may need to be pressed deeper to achieve a deceleration effect. This may indicate that brake pads worn down to the base and damaged the surface of the disc, or the disc itself has lost its frictional properties.
Sometimes owners are faced with the fact that after replacing the pads, braking becomes ineffective or a grinding noise appears. In such cases, the discs are often to blame, the surface of which has been contaminated with oil or has carbon deposits that cannot be removed by normal cleaning.
Particular attention should be paid to the condition of the protective coating on the discs. Corrosion, which often occurs in winter due to reagents, can over time lead to the formation of deep pits that interfere with the uniformity of contact with the pads.
Manufacturer's choice: Original or analogues?
The aftermarket offers a wide selection of rear brake disc manufacturers for Nissan Qashqai J11. The official original (Nissan) is guaranteed to meet all parameters, but its cost is often inflated, and delivery times can be long. Many car owners are looking for worthy alternatives that are not inferior in quality, but are cheaper.
Among the proven analogues, it is worth highlighting such brands as TRW, Brembo, ATE and Textar. These companies are suppliers to many automakers and produce products that meet strict quality standards. Original wheels from these brands often come in the same packaging as spare parts for dealers, but with a different part number.
- 🔧 TRW - a German brand characterized by high wear resistance and an excellent balance of price and quality.

The process of replacing rear discs: step-by-step instructions
Replacing rear brake discs with Nissan Qashqai J11 requires certain skills and special tools, especially due to the peculiarity of working with an electronic handbrake. The process begins with preparing the car: you need to place it on a flat surface, secure the front wheels with stops and engage neutral gear.
The most difficult step is retracting the caliper piston, since the J11 uses an electromechanical handbrake actuator. It is not possible to simply compress the piston with a clamp, as with conventional mechanical brakes. You must either use a special scanner to put the caliper into service mode, or use a mechanical adapter to rotate the piston.
☑️ Preparation for replacement
After removing the wheel and dismantling the brake pads, it is necessary to unscrew the caliper guides and remove the caliper itself, hanging it on a wire so as not to damage the brake hose. Then the bolt securing the caliper to the bracket and the bracket itself, which often sticks due to corrosion, are unscrewed.
The disc is attached to the hub with one screw, which can be heavily pinched by rust. Use a quality socket wrench and penetrating lubricant if necessary to unscrew it. After removing the old disc, clean the hub seat of any rust or dirt so that the new disc will sit smoothly.
Installing a new disc is done in the reverse order, but before doing this you need to make sure that the caliper piston is completely recessed. If you did not use a scanner and used the mechanical method, make sure that the piston is turned to the correct position for installing the pads.
What to do if the piston does not compress?
If the piston does not compress manually, try pressing the handbrake button several times in "Service Mode" (via the on-board computer), or use a special tool to screw in the piston.
After assembly, be sure to bleed the brake system if the hose was damaged during the work or the caliper was completely removed. Check the operation of the electronic handbrake, making sure it is holding the rear wheels correctly.
The nuances of working with an electronic handbrake
Electronic parking brake (EPB) on Nissan Qashqai J11 is a system that requires a special approach when servicing. If you try to replace pads or discs without putting the system into service mode, you can burn the drive motor or break the piston mechanism.
For safe maintenance, there are two main methods for placing a system into maintenance mode. The first method is to use professional diagnostic equipment (OBD scanner), which connects via an interface to the brake control unit and sends a command to open the pistons. This is the most reliable and recommended method.
The second method is to use a specialized mechanical tool that is inserted into a groove on the piston and allows it to rotate and compress at the same time. This method requires care and understanding of the mechanism, as incorrect force can damage the threads or plastic of the piston.
This is often done automatically the first time you press the brake pedal or through the on-board computer menu.
If you are not confident in your abilities, it is better to entrust the work to specialists, since an error in working with the electronic handbrake can lead to expensive repairs of the drive or complete failure of the parking brake system.
⚠️ Attention! Never try to forcefully compress the electronic caliper piston without putting the system into service mode - this is guaranteed to cause damage to the mechanism.

Some manufacturers offer discs with a protective coating that prevents rapid corrosion of the central part of the disc, maintaining its aesthetic appearance and preventing the mounting screws from jamming.
The choice of manufacturer depends on your financial capabilities and driving style, but skimping on brakes is a risk to your life.
Caring for and extending the service life of the brake system
Even the highest quality rear brake discs require proper care and operation. One of the main enemies of the braking system is overheating, which occurs during prolonged braking from high speed or when towing a trailer. Avoid hard braking if possible and use the engine to slow down in mountainous areas.
Regular cleaning of wheels and brake mechanisms from dirt, dust and reagents significantly extends the service life of discs. In winter, after driving on salty roads, it is recommended to wash the brake discs and calipers with water to remove harsh chemicals.
It is also important to monitor the condition of the brake pads. If the pads are worn unevenly or have defects, they will damage the surface of the disc, causing deep grooves and runout. Replace pads and rotors as a set to ensure maximum braking performance.
Do not allow oil or brake fluid to come into contact with the surface of the disc. Even a small amount of oil can cause hot spots and warp on the disc. When changing engine oil or doing other work under the hood, use extreme caution.
If you notice that the car begins to pull to the side when braking, immediately carry out diagnostics. This could be a sign of a stuck caliper or uneven disc wear, which requires urgent attention.
⚠️ Attention! Using low-quality brake fluid with a low boiling point can lead to the formation of vapor locks and complete brake failure if overheated.
Periodically lubricate the caliper guides with a special high-temperature grease to prevent them from seizing and uneven pad wear.
Frequently asked questions and answers (FAQ)
Is it possible to change only one rear disc?
No, you only need to replace rear brake discs in pairs. Installing a new disc on only one side will result in uneven braking, the vehicle pulling to the side and increased stress on the caliper and wheel bearing on the opposite side.
How to put the electronic handbrake into service mode without a scanner?
Without a scanner, doing this is extremely difficult and risky. Some models allow you to use a combination of buttons in the car menu, but for Nissan Qashqai J11 most often requires a diagnostic tool or a special mechanical adapter for the piston. Do not try to compress the piston by force.
Why do new brake discs squeak?
Creaking can occur due to lack of grinding in of new pads and discs, the presence of a protective coating on the discs that needs to be wiped off after the first rides, or due to dust and dirt getting into the mechanism. If the creaking does not go away after 100-200 km, check the quality of installation and compatibility of materials.
What is the service life of rear discs on Qashqai J11?
Service life depends greatly on driving style and operating conditions. On average, rear discs last from 60,000 to 100,000 km. However, with aggressive driving or frequent use of the handbrake, the service life may decrease to 40,000 km.
Do I need to grind discs when replacing pads?
Grooving is possible only if the thickness of the disc allows it (at least the minimum permissible value). However, on modern cars such as Nissan Qashqai J11, it is often recommended to completely replace the discs along with the pads to ensure maximum safety and efficiency.
⚠️ Attention! Check the brake fluid level in the reservoir regularly as wear on the brake pads and rotors causes the fluid level to gradually rise, which may indicate a leak if the level drops suddenly.
