A Complete Guide to Replacing Rear Brake Pads on a Nissan Terrano

The braking system is a critical safety element of any vehicle, and Nissan Terrano is no exception. Timely replacement of rear pads is not just a maintenance requirement, but a necessity that extends the life of expensive parts of calipers and discs. Ignoring wear can lead to mechanism jamming, overheating and complete loss of braking efficiency on the rear axle.

Replacement procedure on a crossover Nissan Terrano has its own technical features, which often distinguish it from other models of the concern. Unlike the front wheels, where the process is usually intuitive, rear calipers require special attention to the piston pressing mechanism. Incorrect actions when compressing the piston can lead to damage to the internal threads or destruction of the o-rings, which will entail costly repairs.

Many owners are faced with the fact that after replacing the pads, a strange squeak is heard or the pedal feels beating. This is often due to improper grinding in of new consumables or insufficient cleaning of the guides. In this article, we will analyze in detail all stages of the work, from preparing tools to final inspection, so that you can complete the task efficiently and safely.

Wear diagnostics and workplace preparation

Before you begin dismantling the wheels, you need to make sure that replacement is necessary. Brake pads on Nissan Terrano usually have a resource of about 40–50 thousand kilometers, but the actual service life depends on driving style and road conditions. The easiest way to check is a visual inspection through the spokes of the disc, if the caliper design allows it, or removing the wheel.

If the thickness of the friction lining is less than 3 mm, repairs cannot be delayed. Pay attention to the wear indicator - a metal plate that, when a critical minimum is reached, begins to touch the brake disc, producing a sharp metallic sound. This is a signal for immediate intervention, as further friction of metal on metal will lead to damage. brake disc.

Preparing the workplace requires a level platform, preferably with an inspection hole or overpass, although you can do without them if you have a reliable jack. Do not forget to prepare the wheel chocks and set the car to the handbrake, but before starting work it will need to be loosened, since the parking brake mechanism is assembled with the rear pads.

To work, you will need a standard set of tools: socket wrenches for 12, 14 and 17, a ratchet with an extension, a mounting blade, as well as a special tool for recessing the caliper piston. If you don't have a specialized tool, you can use old blocks and a vice, but you need to act extremely carefully so as not to damage caliper piston.

Attention ⚠️: Before starting work, be sure to check the brake fluid level in the expansion tank. When the piston returns to its original position, the fluid level will rise, and if the reservoir is full, it can overflow onto engine parts or the body, leading to corrosion and damage to the paintwork.

Selection of consumables and analogues

The quality of brake pads directly affects safety. Original parts number D5201-3HM0A (for front axles, rear axles may differ depending on the year of manufacture) are considered the standard, but their cost is often overpriced. There are many high-quality analogues on the market that offer the best price-quality ratio.

When choosing a brand, you should focus on trusted manufacturers. Among them stand out Nisshinbo (often a supplier to the conveyor), TRW, Textar and ATE. These companies use modern friction compounds that provide stable braking even at high temperatures and do not emit harmful smoke.

• 🛑 Nisshinbo - the best choice for those who want to get original quality at a more affordable price.
• 🛑 TRW - excellent rigidity and absence of squeaks, but sometimes require more thorough grinding.
• 🛑 Textar - premium segment, providing soft braking and no dust on the discs.

Avoid buying cheap Chinese analogues from unknown brands. Their friction composition is often unstable: when heated, it can “float”, which will lead to a sharp decrease in braking force. In addition, such pads often have uneven thickness, which causes the steering wheel to wobble and the pedal to vibrate when braking.

It is also worth paying attention to the completeness. High-quality kits often include not only the pads themselves, but also new caliper guides, as well as lubricant for them. Using old grease, which may have already lost its properties and become clogged with dust, is a common mistake that leads to caliper jamming.

Attention ⚠️: When purchasing pads, be sure to check the markings on the package. For rear wheels Nissan Terrano There are different modifications depending on the type of brake system (with discs or drums, although this model has discs almost everywhere). If you mix them up, you will not be able to install the part in place.

Step-by-step instructions for dismantling and replacement

We begin the process by removing the car from the handbrake. Loosen the wheel nuts on the rear wheels without lifting the car. Raise the car with a jack, install a safety stand and remove the wheel. You now have access to the caliper and brake disc.

Caliper Nissan Terrano secured with two guide bolts. They usually have a spanner size of 14 or 17 mm. Unscrew the lower and upper caliper bracket mounting bolts. Be careful: after unscrewing, the bracket should not be left hanging on the brake hose, as this may damage its internal structure. Hang the bracket on a wire or hook.

Remove old pads. They are usually held in place by compression springs or clamps. Carefully remove them, being careful not to damage the piston protective boots. Inspect the piston: if it is very dirty or has deep scratches, it may need to be replaced or the caliper overhauled.

Clean the seats on the caliper bracket with a wire brush. Remove all brake dust and rust. This is critical to ensure that the new pads move freely and do not bind. Apply a special high-temperature grease to the contact points between the pads and the metal of the bracket, avoiding getting the grease on the friction lining.

The most crucial moment is the compression of the piston. Rear calipers on Nissan Terrano are equipped with a hand brake mechanism, so the piston cannot simply be pressed in with a pry bar. It is necessary to rotate it clockwise while pressing at the same time. A piston compression tool or adapter is ideal for this.

Attention ⚠️: If you use a vice and old pads to compress the piston, make sure that the pressure is distributed evenly. Misalignment can lead to damage to the threaded part of the piston, after which the handbrake mechanism will stop working.

Install the new pads in place. Make sure they fit snugly in the bracket and have no play. Replace the pressure springs if necessary. Carefully place the caliper bracket back onto the brake rotor and tighten the guide bolts to the specified torque (usually around 25-30 Nm).

Repeat the procedure for the second wheel. After installing both wheels, press the brake pedal all the way down several times so that the pistons are in the correct position and the pads are pressed against the disc. Only after this can you move off.

What to do if the piston does not compress?

If the piston does not move, check whether the brake fluid reservoir is open. If the problem is in the handbrake mechanism, the cable may be too tight or the mechanism may be soured. Try releasing the handbrake cable slightly before the procedure.

The nuances of working with the handbrake mechanism

A feature of the rear calipers is Nissan Terrano is an integrated parking brake mechanism. This makes the replacement process more difficult, but makes the system more reliable in the long run. Understanding how it works will help you avoid mistakes during maintenance.

The mechanism operates on the principle of a screw drive. When the piston turns, a force is created that moves the pads apart. If you simply push the piston in without rotating, you risk breaking the internal threads or the piston. This is one of the most common mistakes made by beginners, leading to the need to replace the entire caliper assembly.

Sometimes a situation arises when the piston compresses with great difficulty. This may be due to the handbrake mechanism not being completely disassembled or the parking brake cable being too tight. In such cases, it is recommended to disconnect the cable from the brake lever before starting work.

After replacing the pads, be sure to check the operation of the handbrake. It should fix the car on a slope, but there should not be a feeling that the pads are “squeezed” and the disc continues to rotate with difficulty. If the handbrake does not hold, you may need to adjust the cable or replace the pads with better ones.

Attention ⚠️: Do not use lubricant on the threaded part of the handbrake piston. This may cause the mechanism to spontaneously open or jam. Only the outer guides and contact points of the pads can be lubricated.

Running in new pads and checking functionality

Immediately after replacing the pads, you should not start active driving. New friction linings require a break-in period, which is usually the first 200–300 kilometers. Braking force may be slightly reduced during this period, so keep your distance and avoid sudden braking.

During the running-in process, ideal contact is formed between the friction layer of the pad and the surface of the brake disc. If you perform emergency braking at this moment, overheating spots may form on the disc, which will lead to deformation and beating of the pedal in the future.

Pay close attention to the sounds for the first few days. A slight squeak at the beginning of the movement may be normal if it disappears after a few presses of the pedal. However, a constant metallic grinding or whistling noise indicates that the pads are not installed correctly or that they have become greased.

Check the brake fluid level again after a couple of days of use. As the pads shrink, the level may drop slightly, which is normal. If the level drops quickly, this may indicate a leak in the system or improperly installed seals.

To monitor the effectiveness of braking, you can conduct a test on a level surface. Accelerate to 40 km/h and press the pedal gently, then repeat with more force. The machine should stop smoothly, without pulling to the side or vibrations.

Attention ⚠️: If after replacing the pads you feel that the brake pedal has become “wobbly” or sinks, stop immediately. This could mean there is air in the system or the pistons are not installed correctly. Check the tightness of all connections.

Comparison of original and non-original solutions

The choice between original parts and analogues is always a compromise between cost and quality. Original pads Nissan provide maximum compatibility and predictable behavior, but their price often exceeds the market price.

Characteristics	Original (Nissan)	High-quality analogue (Nisshinbo/TRW)	Budget analogue
Service life	40–50 thousand km	35–45 thousand km	20–30 thousand km
Braking distance	Optimal	good	Increased
Dust on disks	Minimum	Moderate	High
Creaks and noises	Rarely	Sometimes when grinding in	Often
Price	High	Average	Low

Analogues from leading manufacturers often surpass the original in some respects, for example, resistance to overheating or lack of dust. However, cheap fakes can not only wear out quickly, but also damage the brake disc, which will ultimately cost more than buying a high-quality original.

Incorrectly selected pads can lead to complete brake failure in an emergency situation.. Therefore, if you are not sure of the quality of the analogue, it is better to overpay for a proven brand or original.

When choosing, also consider climatic conditions. For winter use, pads with a softer compound that do not harden in the cold are better suited. In summer, you can use more rigid compounds that are resistant to high temperatures.

Common replacement mistakes and how to avoid them

One of the most common mistakes is ignoring the condition of the caliper guides. If they are soured or worn, the caliper will not press the pads evenly, which will lead to rapid wear and overheating. Always check their mobility and change if necessary.

Another mistake is using the wrong lubricant. Regular lithium grease or WD-40 are not suitable for the brake system. They can soften when heated and leak, or, conversely, thicken and jam the mechanism. Use only special high-temperature caliper grease.

Incorrect installation of pressure springs can also cause problems. If the spring does not provide a tight fit between the pad and the bracket, vibration and squeaking will occur. Make sure the springs are installed correctly and are not deformed.

Sometimes owners forget to remove the protective caps from the guides before lubricating or cleaning them. This leads to dirt and dust getting inside the mechanism, accelerating its wear. Always remove the caps, clean the guides and reinstall them with new grease.

Attention ⚠️: Never use gasoline or solvents to clean the brake system. They can damage rubber seals and boots. Use special brake cleaner or alcohol.

Conclusion and recommendations for maintenance

Replacing rear pads with Nissan Terrano - a task that is quite possible to perform independently with a minimum set of tools and accuracy. The main thing is to follow the sequence of actions and not neglect the little things, such as cleaning the seats and proper lubrication.

Regularly checking the condition of the brake system will help avoid unexpected breakdowns and ensure your safety on the road. Don't wait until the pads are completely worn out and replace them at the first sign of wear. This will save you money on repairing more complex components in the future.

If you doubt your abilities or do not have the necessary tools, it is better to entrust this work to professionals. However, knowledge of the process will allow you to control the quality of the work performed and will not allow the craftsmen to save on important stages of maintenance.

Remember that your brakes are your life and the lives of your passengers. Treat their maintenance with maximum responsibility and attention to detail. Regular maintenance and the use of high-quality spare parts are the key to long and reliable operation of the car.

How often do you need to change the rear pads on a Nissan Terrano?

The recommended replacement interval is 40–50 thousand kilometers, but the exact period depends on operating conditions and driving style. Check the thickness of the friction lining regularly.

Is it possible to replace the pads without removing the caliper?

No, to replace the pads you must remove the caliper bracket to remove the old parts and install the new ones. This is standard procedure for most disc brakes.

What should I do if the rear caliper piston does not compress?

The rear caliper piston must be rotated clockwise when compressed. Use a special tool to compress the pistons. Do not apply force without rotation to avoid damaging the mechanism.

Do I need to change the brake fluid when replacing the pads?

When replacing pads, it is not necessary to change the fluid, but it is recommended to check its condition. If the fluid is old (more than 2 years), it is better to replace it as part of scheduled maintenance.

Why do new pads squeak?

The squeaking noise can be caused by insufficient grinding, lubricant getting on the friction lining, or poor quality material. In most cases, the squeak disappears after 100–200 km.
