Crossover operation Nissan Qashqai the second generation (J11), in conditions of dense city traffic or aggressive driving on the highway, places increased demands on the braking system. It is the front wheels that take on up to 70% of the total braking load, which makes the condition front brake pads critical for the safety of the driver and passengers. Ignoring signs of wear can lead to warped brake discs, which will significantly increase the cost of repairs.
Owners Nissan Qashqai J11 often face a dilemma: choose original parts or trust proven analogues. The auto parts market is oversaturated with offers where counterfeits with low heat transfer can be sold under the guise of a quality product. To avoid premature failure of the brake system, it is necessary to understand the design features of the calipers, the types of materials used and the criteria for proper selection.
Design features and sizes of the J11 brake system
Crossover braking system Nissan Qashqai The J11 has its own unique nuances, which depend on the year of manufacture, engine size and type of suspension installed. Most versions with a 2.0-liter gasoline engine use calipers with a piston diameter of 46 mm, while versions with a 1.2 DIG-T may have more compact mechanisms. It is important to consider that there may be different brake suppliers on the same model, for example Akebono or TRW.
The size of the pads is not universal for all years of manufacture. Depending on the body type (J11 or restyled J11) and the level of equipment, the length of the friction lining can vary from 145 to 155 mm. An incorrect selection from the catalog can lead to the fact that the new part simply will not fit into the caliper or will touch the protective casing. Before purchasing, be sure to check the part number with the VIN code of your car.
Particular attention should be paid to the presence of a wear sensor. In many markets, including Europe and Russia, the front pads are equipped with an electrical contact that closes when the critical thickness of the friction layer is reached. This sensor activates a light on the dashboard to alert you when replacement is required. In some budget versions, the sensor may be missing, which requires visual inspection of the thickness of the lining.
Original spare parts versus high-quality analogues
Original part from Nissan under article number D1060-1AA0A (or its modifications) is a quality standard, as it was developed by plant engineers taking into account all operating modes. Such pads provide stable friction, do not generate excessive dust and do not produce extraneous sounds when braking. However, their cost is often 2-3 times higher than similar products from third-party brands, which forces owners to look for alternatives.
Analogs from the world's leading manufacturers often surpass the original in their characteristics, especially in terms of heat resistance and service life. Brands that specialize in braking systems use modern composite materials that dissipate heat better and are less susceptible to degradation at high temperatures. Choice in favor high-quality analogue can be cost-effective while maintaining or even improving safety.
When choosing alternative options, you should pay attention to the composition of the friction mixture. Metallic (semi-metallic) linings provide excellent braking performance, but can quickly wear out the brake rotors. Organic (non-asbestos) materials are quieter and gentler on discs, but wear out faster during aggressive driving. For Nissan Qashqai J11 Semi-synthetic compounds are considered the optimal balance.
Here are the main manufacturers whose products have proven themselves to be the best:
- πΉ TRW - German quality, often used as an original supplier, excellent stability of the friction coefficient.
- πΉ ATE is a premium brand offering pads with high service life and low noise levels.
- πΉ Textar - reliable products that often come complete with original packaging on the conveyor.
- πΉ Remsa β a budget but decent option, suitable for quiet city driving.
- According to the regulations (once every 30-40 thousand km)
- When a squeak appears
- When completely erased
- I don't remember the last time I changed it
Symptoms of wear and condition diagnosis
The need for replacement can be determined not only by the readings of the on-board computer, but also by a number of external signs. The most obvious signal is the appearance of a metallic squeak or grinding sound when you lightly press the brake pedal. This sound is caused by the contact of the wear indicator or the metal base of the pad itself with the surface of the disc.
In addition to acoustic signals, the driver may notice a change in the vehicle's behavior when braking. If the pedal becomes more βwobblyβ or requires more force to stop, this may indicate overheating or degradation of the friction layer. Also pay attention to the beating of the steering wheel during heavy braking - this often indicates that the pads have not been changed for a long time and the discs have undergone thermal deformation.
Visual diagnosis is the most accurate method. After removing the wheel, you can estimate the remaining thickness of the friction lining. If the layer is less than 2-3 mm, operation becomes dangerous. It is important to check not only the thickness, but also the uniformity of wear over the entire area of ββthe pad, since uneven wear indicates problems with the caliper guides.
β οΈ Attention: Ignoring squeaking or vibration when braking can lead to complete destruction of the friction material, which will cause the steel base of the pad to grind down the brake disc. In this case, replacing the pads will no longer help - you will need an expensive replacement of the discs and, possibly, the caliper itself.
Step-by-step instructions for replacing front pads
The process of replacing front brake pads Nissan Qashqai J11 does not require complex special equipment, but requires care and precision. It is better to carry out the work on a level area, using a jack and reliable stands. Before starting work, be sure to release the handbrake and loosen the wheel bolts while the vehicle is standing.
To complete the work, you will need a standard set of tools: socket wrenches (usually 17 and 14), a hexagon (often 7 mm for caliper guides), a mounting blade and brake system cleaning fluid. Use W675 or similar lubricant for the caliper guides to prevent them from jamming.
Follow this procedure for a safe replacement:
- π οΈ Raise the car, remove the wheel and dismantle the caliper guides holding its body.
- π οΈ Carefully move the caliper up or to the side without bending the brake hose.
- π οΈ Remove the old pads, clean the seats from dust and rust.
- π οΈ Install new pads, having first lubricated the contact points (not the friction part!).
- π οΈ Squeeze the caliper piston and return it to its place, securing the guides.
βοΈ Preparing to replace pads
What to do if the caliper piston does not press? If the caliper piston cannot be pressed with a regular tool, it may be jammed due to corrosion or have a complex shape. In this case, do not use brute force to avoid damaging the cuff. Try using a special puller or carefully turning the piston while pressing on it. On some Nissan models the piston is threaded and must be threaded into the caliper body rather than just pressed in.-->
Pay special attention to cleaning the seats. The buildup of dirt and rust can cause the new pad to jam in the caliper, causing constant heat and rapid wear. Use a wire brush and spray cleaner Brake Cleaner to remove old grease and dust.
After installing new elements, be sure to bleed the brake system if you accidentally disconnected the hose or the piston was extended too far. Before driving, press the brake pedal several times to rub the pads into the disc and restore operating pressure in the system.
