Crossover operation Nissan Juke inevitably leads to wear of the chassis elements, and the brake system is no exception. The rear brakes on this model are often equipped with an electric parking brake, which makes the replacement procedure much more complicated than with conventional mechanical handbrake brakes. Many owners are faced with the need for self-service in order to avoid overpaying at service centers and maintain control over the quality of the spare parts used.
Timely replacement of rear brake pads critical not only for road safety, but also for maintaining the integrity of the brake discs. Ignoring wear can cause the metal base of the pad to come into contact with the disc, causing deep grooves and the need for costly replacement of the discs and calipers. In this article we will look in detail at how to carry out this procedure correctly, what tools will be needed and what pitfalls may arise when working with electronics.
The process requires care, especially when working with electric handbrake, which is on Nissan Juke has no mechanical unlocking without power supply or the use of diagnostic equipment. Incorrect actions can lead to damage to the caliper motor or failure of the system controller. However, by following a clear algorithm and understanding the principles of the mechanism, you will be able to do the job efficiently and safely right in your garage.
Preparation of tools and selection of necessary spare parts
Before you begin physically dismantling the wheels, you need to make sure that you have all the necessary tools and a high-quality set of consumables. For working with suspension and braking systems Nissan Juke a standard set of wrenches may not be enough due to the specific fastenings and design features of the caliper.
You will definitely need a set of sockets, including a 14 mm size for the caliper guides and a 17 mm size for the bracket (depending on the year of manufacture and modification). A torque wrench is also essential for properly tightening fasteners after assembly. If you do not have an OBD2 scanner with brake control, be sure to have a reliable power source available to prevent the electronics from being reset during the procedure.
- 🔧 Socket heads and ratchet driver (10, 14, 17 mm)
- 🔩 Torque wrench (for tightening wheel bolts and guides)
- 🧴Brake cleaner and copper guide grease
- 🔌 OBD2 adapter with "Service Mode" function or external 12V power supply
The choice of pads themselves plays a decisive role in braking performance. For Nissan Juke It is recommended to use original parts or high-quality analogues from trusted brands, such as TRW, ATE or Textar. Cheap Chinese analogues often have uneven wear, create squeaks and can lead to overheating of the caliper.
⚠️ Attention: When purchasing a kit, be sure to check the presence of a wear sensor in the kit, as on some versions Nissan Juke it is a non-removable element of the new pad.
Don't forget to also purchase new caliper guides if the old ones have play or damage to the boots. Guides that are worn out can cause the mechanism to jam, which will lead to constant braking of the wheel and overheating of the brake system during operation.
Step-by-step instructions for dismantling and removing old elements
You should begin work by placing the car on a flat surface and applying the hand brake. If you are changing the pads on only one side, the car must be securely jacked up and placed on a safety stand. Removing the wheel gives access to the caliper, which is Nissan Juke It has compact dimensions and a specific location.
The first step is to clean the area around the caliper guides of dirt and rust using a metal brush and cleaner. This will allow you to easily unscrew the mounting bolts without the risk of tearing them off or damaging the threads. Use a penetrating lubricant if the bolts are stuck, but be careful not to get the product on the brake rotor's working surface.
Next, you need to unscrew the lower caliper guide bolt. The top bolt is often held in place by a lock washer that must be carefully bent back. After unscrewing the bolts, the caliper can be removed from the guides, but this must be done so as not to damage the flexible brake hose. Hang the caliper on a wire or hook so that it does not hang on the hose.
- 🚗 Loosen the wheel bolts before lifting the car to avoid wheel spin
- 🛠️ Use penetrating lubricant 10-15 minutes before unscrewing the caliper bolts
- 🔒 Be sure to place a support under the lever or body for safety
- 🧤 Wear protective gloves as brake dust is very toxic
After removing the caliper, you will see old brake pads that may be stuck to the guides. Carefully remove them using a pry bar or flathead screwdriver, but do not use excessive force to avoid damaging the bracket. Inspect the brake rotor for scoring, scoring, or uneven wear.
If the disc has significant damage, it must be replaced or sharpened, but this is a separate procedure. Ideally, the surface should be smooth, without deep marks. Also check the condition of the caliper guide boots - they should be intact and elastic, without cracks or signs of lubricant leakage.
Features of working with an electric parking brake
The most difficult step when replacing rear pads is Nissan Juke is the need to recess the caliper piston back into the body. Unlike front brakes, where the piston is simply pressed in, this one uses an electric mechanism, which requires a special maintenance regime. Without switching to this mode, you will not be able to press the piston, and trying to do this by force will lead to damage to the electric motor.
To put the system into service mode, you will need a diagnostic scanner that supports the "Service Mode" function for the rear parking brake. When you connect the scanner to the OBD2 connector and select the appropriate option, the electric motors on both rear wheels will begin to rotate, pushing the pistons back. This happens automatically and takes a few seconds.
If you don't have access to professional equipment, there is an alternative method, but it requires an external 12V power supply and some skill. However, this method is less reliable and may cause errors in the system, so using a scanner is highly recommended. An attempt to mechanically press the piston without turning off the drive is guaranteed to break the mechanism.
- 📡 Use a scanner with Nissan support or a universal one with the necessary functions
- 🔋 Connect an external 12V power supply to the battery to prevent discharge
- ⚙️ Make sure the ignition is on but the engine is not running during the procedure
- 🛑 Do not touch the brake pedal while moving the pistons into service mode
⚠️ Attention: If after the maintenance procedure the EPB error lamp on the dashboard lights up, you must perform the initialization procedure via a scanner or reset the errors using diagnostic equipment.
After the pistons are completely retracted into the housing, you can begin installing new pads. Before doing this, be sure to clean the seats on the bracket and apply a special high-temperature grease to the contact pads. This will ensure the pads move freely and prevent squeaks in the future.
- Every 20,000 km
- Every 40,000 km
- Only when they creak
- I don't know when to change
Installing new pads and reassembling the mechanism
With installation of new brake pads problems usually do not arise if the piston has been recessed correctly. Install the new elements into the bracket, making sure they move freely in the guides. On some models Nissan Juke Special latch springs or brackets may be installed, which also need to be replaced or rearranged if they are not worn out.
Before installing the caliper in place, check the condition of the guide boots. If they are damaged, replace them along with the guides, as dirt getting inside can quickly damage the mechanism. Apply a thin layer of copper grease to the contact points between the caliper and the steering knuckle, but avoid getting the grease on the brake rotor or pad surfaces.
Install the caliper onto the guides and tighten the mounting bolts to the recommended torque. Usually this value is about 25-30 Nm, but it is better to check the exact data in the service book for your specific modification. After tightening, check whether the caliper is touching the disc or other suspension elements.
- 🔩 Tighten the guide bolts with a torque wrench
- 🛡️ Check the integrity of the anthers before final assembly
- 🧼 Clean the brake disc from grease and dirt before installing the wheel
- 🔊 Make sure the pads are not loose in the bracket after installation
After installing the wheel, lower the vehicle to the ground and tighten the wheel bolts to the recommended torque. Don't forget to remove the safety stands and make sure the car is stable. Now you need to perform the procedure for exiting the service mode and check the operation of the brakes.
☑️ Check before travel
Checking and running in the new brake system
Before you start driving, you must make sure that the system is working correctly. Turn the ignition on and check that all warning lights on the instrument panel related to the brake system and electronic handbrake have gone out. Try pressing the brake pedal several times so that the pistons reach their stroke and the pads press against the disc.
Start the engine and check the parking brake. When you press a button or handbrake lever, the characteristic sounds of electric motors should be heard, and the indicator on the panel should light up and go out. Make sure the vehicle is securely supported on the slope and does not roll away.
The first 100-200 kilometers are considered the break-in period for new pads. During this time, avoid sudden braking and extreme loads so that the pad material is evenly worn in to the disc surface. This will ensure maximum braking performance and extend the life of both elements.
If after break-in you notice squeaks, vibrations or uneven wear, you need to return to the diagnosis. Perhaps mistakes were made during installation, or the quality of the new pads leaves much to be desired. In this case, it is better to contact specialists for re-checking.
⚠️ Attention: If the brake pedal becomes soft or falls out, stop immediately and check the system for leaks and air in the brake lines.
Common mistakes and ways to prevent them
One of the most common mistakes is ignoring the need to clean and lubricate the caliper guides. Many owners believe that this is a waste of time, but it is the contamination of the guides that most often leads to jamming of the caliper and rapid wear of the pads on one side.
Another mistake is using the wrong lubricant. Regular lithium grease or graphite paste is not suitable for brake systems as it can melt at high temperatures and cause seizure. Use only special high-temperature lubricants intended for brake mechanisms.
It is also worth noting an error related to incorrect installation of the wear sensor. If the sensor is installed incorrectly or damaged during installation, it can transmit false signals to the dashboard, forcing the owner to replace working pads ahead of time.
| element | Recommended replacement interval | Signs of wear | Average cost |
|---|---|---|---|
| Front pads | 30-40 thousand km | Creak, vibration, wear lamp | 3000-5000 rub. |
| Rear pads | 40-60 thousand km | Increasing pedal travel, creaking | 3500-5500 rub. |
| Brake disc (front) | 60-80 thousand km | Deep furrows, steering wheel beating | 4000-7000 rub. |
| Brake disc (rear) | 60-80 thousand km | Cracks, uneven wear | 3500-6000 rub. |
| Caliper guides | According to condition | Backlash, jamming | 1500-3000 rub. |
What to do if the piston does not go into the housing?
If the piston does not move, check the brake fluid level in the reservoir - it may be overfilled. Also make sure that you have actually put the system into service mode. In rare cases, it may be necessary to replace the caliper motor if it fails due to mechanical pushing.
When replacing pads, always replace them as a set on the same axle (both sides) to ensure even braking and prevent the vehicle from pulling to the side.
The key to a successful replacement is the correct transition of the electromechanism to the service mode without attempting to exert mechanical force on the piston.
FAQ: Answers to frequently asked questions from owners
Is it possible to replace rear brake pads on a Nissan Juke without a scanner?
Without a scanner this is extremely difficult and risky. Some craftsmen use a method with external power and closed contacts, but this requires in-depth knowledge of electrical engineering. It is recommended to use an OBD2 scanner with EPB control function to avoid motor damage.
How often should you change brake pads on a Nissan Juke?
The interval depends on driving style and operating conditions. On average, rear pads last 40-60 thousand kilometers. Regularly check the thickness of the friction lining visually through the holes in the disc or on the lifter.
Why do new pads squeak after replacement?
The creaking can be caused by a lack of lubrication on the contact pads, the presence of air in the system, or low-quality spare parts. Also, sometimes it takes time to break in for the friction material to evenly break in to the disc.
Do I need to change the brake fluid when replacing the pads?
Replacing the pads does not necessarily require changing the fluid, but it is recommended to check its condition every 2 years. If the fluid is dark or contains moisture, it is best to replace it to avoid corrosion of the brake system and loss of performance.
What should I do if the EPB error comes on after replacement?
The EPB error often occurs if the procedure for exiting the service mode was not completed correctly. Try rebooting the system by disconnecting the battery for 10-15 minutes. If the error does not disappear, diagnostics with a scanner will be required to reset the error codes.
