Crossover operation Nissan Terrano third generation in conditions of Russian roads requires close attention to the condition of the chassis, especially the braking system. Rear brakes often operate in a less aggressive mode compared to the front ones, but this is where more dirt and moisture accumulates, which accelerates wear of the parts. Timely diagnosis and replacement brake pads is not just a matter of comfort, but the foundation of traffic safety.
Many car owners are faced with the misconception that the rear pads are Nissan Terrano can be changed as easily as on the front axles. This misconception can lead to breakdown of the electronic mechanism or disruption of the stabilization system. In this article we will analyze the nuances of the design, the necessary tools and the sequence of actions so that you can do the work yourself and without errors.
Specifics of the rear brake design on Terrano 3
Car rear axle Nissan Terrano is equipped with disc brakes, but their design has a number of differences from the front units. The main nuance is the presence of an integrated mechanism electronic parking brake (EPB). Unlike mechanical handbrake levers, here the drive is carried out not by a cable, but by a servo drive built into the caliper.
When replacing pads, it is necessary to take into account that the caliper piston is not simply pressed in, but requires a special return algorithm. If you try to compress the piston using the usual clamp method without first switching to service mode, you risk damaging the gears of the EPB mechanism gearbox. This will lead to costly repairs and the need to replace the entire caliper.
It is also worth noting that pads with integrated wear sensors are often used on the rear axle. They must be checked every time they are replaced. Ignoring the wear signal may result in metal base the pads will begin to wear out the brake disc, which will increase the cost of repairs significantly.
⚠️ Attention: Never disconnect the battery before starting work on the electronic parking brake unless you have put the calipers into service mode via the on-board computer or diagnostic scanner.
Tools and necessary materials for work
Before starting work, make sure you have a complete set of tools. For Nissan Terrano You will need both a standard set of keys and specialized tools. Without the right tools, the process may take longer or damage the fasteners.
You will definitely need:
- 🔧 Set of sockets and ratchets (including 14, 17 and 21 mm sockets)
- 🔩 Wrench for the hub nut (usually 30 mm or a special puller)
- 🔨 Hammer and pry bar for removing stuck parts
- 📏 Caliper for measuring the thickness of the brake disc
- 🔌 Diagnostic scanner or OBD2 adapter for EPB management
Also, don't forget cleaning products and lubricants. Be sure to use lubricant for caliper guides based on silicone or a special composition for brake systems. Regular lithium grease or WD-40 are absolutely not suitable here, as they can destroy the rubber seals.
To work you will also need a set of new brake pads. When choosing a spare part, pay attention to the manufacturer and compatibility index. Original parts from Nissan are often marked to match your VIN to ensure a perfect fit.
☑️ Preparing to replace pads
Selection of quality spare parts and consumables
The auto parts market offers a huge selection of options for Nissan Terrano. However, not all of them are suitable for long-term use in our climatic conditions. Cheap analogues often have an uneven composition of the friction layer, which leads to vibrations during braking and noise.
There are several proven brands that have proven themselves to be the best. Among them we can highlight TRW, Brembo, Akebono and Remsa. These manufacturers supply spare parts to the assembly line, so their quality is as close as possible to the original.
When choosing, it is also important to consider operating conditions. If you often drive off-road or in city traffic with frequent traffic jams, it is better to choose pads with increased heat resistance. They generate less dust and provide stable power even under high heat.
Pay attention to the brake discs. If they have deep grooves or runout, replacing the pads alone will not give the desired result. In this case, it is necessary to drill out or replace the disks. Optimal disc thickness for Terrano 3 indicated in the service book, but usually it is at least 20 mm.

Step-by-step instructions for dismantling and replacement
The replacement process begins with preparing the car. Raise the back Nissan Terrano on a jack and be sure to install safety stands. Remove the wheel and clean the caliper of dirt and corrosion with a wire brush.
The first step is to remove the brake caliper. Remove the two guide bolts holding the caliper bracket in place. They are usually 14mm or 17mm in size. Carefully remove the caliper and hang it on a wire so as not to damage the brake hose.
Now you need to remove the old pads. They may be stuck to the bracket, so use a pry bar. Inspect the guide pins - if they are jammed or damaged, they need to be replaced. This is a common reason why rear pads wear unevenly.
The next step is working with the caliper piston. Here you will need a diagnostic scanner. Connect it to the OBD2 connector, start the engine and go to the control menu electronic parking brake. Select "Reset to Service Mode" or "Retract Caliper".
After the piston goes inside, you can install new pads. Apply a thin layer of high temperature grease to the back of the pads and where they contact the metal bracket. Make sure the pads are tight and not loose.
Reinstall the caliper and tighten the guide bolts to the torque specified in the instructions. Don't forget to check the condition of the boots on the guides - if they are torn, moisture will get inside and cause corrosion.
What to do if you don't have a scanner?
If you do not have a diagnostic scanner, you can try the mechanical method, but it is risky. Sometimes the piston can be pressed in after unscrewing the bleeder fitting, but this requires caution and may allow air to enter the system. It is best to rent a scanner for a day or contact a service to switch it to service mode.
Final check and pumping features
After installing all the wheels, it is necessary to conduct a test run. Before starting to move, press the brake pedal several times until it stops so that the pistons are in place. If the pedal is soft or sinks, there may be air left in the system.
Bleeding the rear brakes Nissan Terrano has its own characteristics due to the presence of EPB. In some cases, it is necessary to reconnect the scanner to exit the service mode. If this is not done, the brakes may not work correctly or an error light may appear on the instrument panel.
Carefully check the brake fluid level in the expansion tank. When replacing pads, the pistons go deeper and the fluid level may rise. If it is too high, some of the liquid must be drained to avoid overflow when heating.
For the first 100-200 kilometers after replacement, avoid sudden braking. This time is necessary for the friction layer to burn in to the disc. Improper running-in can lead to squeaking noises and reduced braking efficiency.
| Parameter | Value for Nissan Terrano 3 | Note |
|---|---|---|
| Brake disc diameter | 300 mm | Standard size for most versions |
| New disc thickness | 24 mm | Minimum permissible - 22 mm |
| Caliper bolt tightening torque | 25-30 Nm | Use a torque wrench |
| Brake fluid type | DOT 4 | Replace every 2 years |
| Guide bolt size | M12x1.25 | Check for anthers |
Proper break-in of new pads in the first 200 km is critical for the formation of ideal contact with the disc and the absence of vibrations during braking.
Common mistakes when servicing the brake system
Many car owners make the same mistakes when trying to save time or money. One of the most common problems is ignoring the condition of the caliper guides. Guides clogged with dirt do not allow the caliper to move smoothly, which leads to jamming of the pads and their rapid wear.
Another mistake is using the wrong lubricants. The guide lubricant must withstand high temperatures and not destroy the rubber. The use of conventional grease or graphite lubricant can lead to swelling of the boots and jamming of the mechanism.
They also often forget about the need to clean the pad seats. If rust and carbon deposits remain on the bracket, the new pads will not fit tightly, which will cause play and a characteristic knock when driving over uneven surfaces. Use a wire brush and brake cleaner before installation.
It is also important not to confuse the left and right sides when installing some types of pads if they are asymmetrical in shape. Although on Nissan Terrano They are usually symmetrical; checking the markings will not be superfluous. An error may result in uneven wear and reduced braking performance.
⚠️ Attention: If you feel a pulsation when you press the brake pedal, the brake disc most likely has runout. In this case, replacing the pads will not solve the problem; resurfacing or replacing the discs will be required.
Diagnosis and prevention of problems
Regular diagnostics of the brake system will help avoid unexpected breakdowns. At each maintenance, pay attention to the condition of the rear calipers. Check for fluid leaks around the pistons and guides.
Pay special attention to the electronic part. If the handbrake or stability control light comes on on the dashboard, this may indicate a malfunction of the piston position sensors or the EPB motor. In such cases, computer diagnostics is necessary.
Also check the condition of the dust caps on the calipers. They protect internal mechanisms from water and dirt. If the cap is torn, moisture will get in and corrode the piston, causing the caliper to leak.
Don't forget about seasonal maintenance. In winter, after trips using reagents, it is recommended to flush the brake system with water. This will remove salt and dirt that accelerate metal corrosion. In summer, it is worth checking the condition of the pads more often due to increased loads.
Before winter use, be sure to check the operation of the electronic handbrake at idle to make sure that it does not freeze and operates correctly at low temperatures.
FAQ: Frequently asked questions
How to determine rear pad wear without removing the wheel?
On many models Nissan Terrano There is a visual wear indicator or sensor that sends a signal to the dashboard. You can also look through the wheel spokes at the thickness of the friction layer, if the disc design allows it.
Is it possible to replace just one pair of pads at the rear?
No, you only need to replace the kit on both sides at the same time. Different wear or hardness of the pads will lead to uneven braking and the car skidding during an emergency stop.
What should I do if the caliper piston does not go back in?
Don't use force. Most likely, the EPB mechanism has not been switched to service mode. Connect the scanner and perform the piston return procedure. If the problem cannot be solved, the gearbox of the mechanism may be damaged.
How often do you need to change the rear pads on Terrano 3?
Service life depends on driving style and operating conditions. On average, pads last from 30 to 50 thousand kilometers. Regularly check the thickness of the friction layer at each maintenance.
Do I need to change brake discs and pads?
Not necessary if the disc thickness is higher than the minimum permissible and there are no deep grooves or cracks on it. However, if the discs are worn to the limit, replacing them is mandatory to ensure safety.
⚠️ Attention: Never try to compress the piston of a caliper with an electronic parking brake without first putting it into service mode through a diagnostic scanner - this is guaranteed to damage the mechanism.
