Proper operation of the parking brake is not just a legal requirement, but a critical element of your safety. Nissan Terrano. Over time, the mechanism stretches, and the handbrake lever has to be raised higher and higher to keep the car on the slope. If you notice that the handbrake only holds the car on the last clicks or the car starts to roll even on a slight slope, it’s time to make an adjustment.
Ignoring this problem can lead to complete failure of the braking system when parking, which can lead to serious accidents and body damage. Owners Nissan Terrano Often they are faced with the fact that after replacing the rear brake pads, tighten the cables, or simply due to natural wear, the tension becomes insufficient. In this article we will look at how to perform this procedure yourself without resorting to the services of an expensive car service.
Signs that your handbrake needs to be adjusted
You can determine that the mechanism requires intervention by several obvious symptoms that appear during operation. The most obvious sign is the number of clicks when lifting the lever. On a working car, the lever should lock in the working position after 2–4 clicks. If you have to lift it up to 6-8 clicks, the cable tension has clearly weakened.
Another warning sign is when the vehicle moves spontaneously on a level surface or when parking on a slope with the parking brake on. In such situations, the car may roll slowly, which indicates that the brake pads are not pressing against the drums with enough force. Also pay attention to the behavior of the car during a sharp start from a standstill: if you forget to completely lower the handbrake, a characteristic burning smell may appear from the rear wheels, which indicates that the pads are jammed, but sometimes on the contrary - they do not press even when lowered.
It is important to carry out diagnostics not only by clicks, but also visually, if possible. An inspection of the rear wheels may reveal uneven wear or overheating of the brake discs (if you have a version with disc brakes at the rear), although most often the problem lies in the extension of the cable. Regular inspection helps avoid costly repairs and extends the life of the entire brake system.
Preparation of tools and workplace
Before starting work, it is necessary to prepare all the necessary equipment so that the process is not interrupted due to the lack of the necessary key or part. You will need a standard set of tools: a ratchet wrench with heads, a set of screwdrivers (phillips and flat), as well as a jack and reliable stands for the car. For Nissan Terrano Often a 10mm socket is required to remove the locknut and adjusting nut.
The work area must be level and firm. Never work under a car that is only supported by a jack, as this can be fatal. Be sure to use safety stands (goats) under the body to eliminate the risk of the car falling. If you are working in a garage, make sure there is enough room to maneuver and that the floor is not slippery from oil.
☑️ Tools for adjusting the handbrake
Don't forget to prepare thread lubricant. Often the nuts responsible for tensioning the cable become stuck to the body, and they cannot be unscrewed without pre-treatment with penetrating lubricant. A flashlight is also useful, since access to the adjustment mechanism is often in a dark space under the car.
Access to the adjustment mechanism
Parking brake adjustment mechanism Nissan Terrano located under the central tunnel, in the rear of the cabin or under the trunk floor, depending on the configuration and year of manufacture. In some cases, access will require removing the plastic lining of the tunnel, which is secured with latches and several screws. By carefully prying the plastic with a screwdriver, you can remove the casing and open access to the adjusting nut.
In other modifications, access is provided directly from under the car. You will need to lift the car on a lift or jack, place it on stands and crawl under the bottom. The adjusting nut is located on the lever that connects the two parking brake cables. Often it is hidden under a protective cover made of rubber or plastic, which must be carefully bent or removed.
Where to look for the adjusting nut?
On most Terrano models, the adjusting nut is located on a bracket under the center console, closer to the floor. Sometimes it is hidden under soundproofing material, which must be pulled back slightly to reveal the metal lever and 10mm nut.
If you have difficulty finding the mechanism, carefully inspect the cables running from the lever in the cabin to the rear wheels. They should converge at one point, where the tension lever is located. This is where the adjustment unit is located. It is important to act carefully so as not to damage the protective covers of the cables, since water and dirt getting inside can lead to jamming of the mechanism in the future.
Procedure for adjusting cable tension
The adjustment process itself requires attention and consistency of actions. First you need to loosen the locknut that secures the position of the adjusting nut. This is done with a 10 mm wrench counterclockwise. After the locknut is released, you can rotate the adjusting nut itself. Clockwise rotation will tighten the cables, while counterclockwise rotation will loosen them.
Rotate the adjusting nut until the desired tension is achieved. The ideal condition is when the handbrake lever rises with a force of 3-4 clicks and securely fixes the car. In this case, the wheels should rotate freely when the lever is lowered. You can check this by asking an assistant to hold the handbrake down while you turn the wheel with your hands.
When adjusting, try not to overtighten the cables, as this can lead to rapid wear of the brake pads and overheating when driving.
After achieving the desired tension, it is necessary to tighten the lock nut, holding the adjusting nut from turning with a second wrench. This is a critical step because as the car moves, vibrations can weaken the connection, causing the handbrake to become loose again. Make sure both keys are pressed tightly together to avoid stripping the threads.
Checking operation after adjustment
After completing the adjustment work, do not rush to lower the car to the ground. Carry out an initial check directly on the stands. Try raising and lowering the handbrake lever several times to make sure it moves smoothly and does not jam. The sound should be clear, without creaks or extraneous noise.
Then lower the vehicle to the ground and perform a slope test. Find a safe place with a slight slope, put the gear in neutral and raise the handbrake the required number of clicks. The vehicle must remain stationary. If the car rolls, the procedure will have to be repeated, slightly tightening the cables even more.
A properly adjusted handbrake should keep the car on a 16-20 degree slope without rolling, and the wheels should rotate freely when the lever is lowered.
It is also important to check the operation of the brakes while driving. Drive at low speed and gently press the brake pedal several times. This will help the pads fall into place. If after adjustment you feel that the car pulls to the side when braking, the cables may not be tensioned evenly and additional adjustments will be required.
Typical errors and problems during maintenance
One of the most common mistakes is over-tightening the cables. Many owners think that the tighter the handbrake is, the better it works, but this is not true. Excessive tension causes the brake pads to constantly contact the drums or discs, causing them to overheat and prematurely wear out. As a result, you may end up with seized wheels or burnt-out brake calipers.
Another problem is uneven tension on the cables. If one cable is tighter than the other, the car will pull to the side during emergency braking or parking on a slope. This creates a dangerous situation, especially on slippery roads. In such cases, it is necessary to check the condition of the cables themselves: perhaps one of them is jammed in the sheath or torn.
- Once a month
- Once every six months
- Only when I notice a problem
- I never check
It is also worth paying attention to the condition of the cable sheaths. If they are cracked or torn, dirt and water can get in, causing corrosion and jamming of the cable. In such situations, simple adjustment will not help; the cables will need to be replaced with new ones. Do not skimp on the quality of spare parts, choose original parts or proven analogues.
When cables or pads need to be replaced
Adjusting the handbrake only helps if the mechanism is working properly, but is simply weakened. However, there are situations when adjustment becomes impossible or meaningless. If you have unscrewed the adjusting nut to the limit, but the tension is still insufficient, this indicates that the cables have stretched critically or the brake pads have worn out.
In the case of Nissan Terrano with rear drum brakes, the wear of the pads is compensated by a self-aligning mechanism, but if the wear is severe, the cables may simply not have a reserve of travel for tightening. In such cases, it is necessary to remove the rear wheels, dismantle the drums and check the thickness of the friction linings. If they are worn down to metal, replacement is required.
| Symptom | Probable Cause | Required action |
|---|---|---|
| The handbrake doesn't hold even at maximum | Severe pad wear or cable breakage | Replacing pads and inspecting cables |
| The wheel does not rotate after adjustment | Tighten the cable or jammed mechanism | Loosen the tension, lubricate the cable |
| Creak when lifting the lever | Rust or lack of lubrication in the cable | Cable replacement or deep lubrication |
| The handbrake sticks and won't go down | Cable sheath jamming | Replacing the cable assembly |
If you find that the cables have visible damage, rust or signs of corrosion, do not attempt to repair them. The safety of the brake system does not allow compromises: if you have the slightest doubt about the integrity of the cable, replace it completely. The cost of new cables is small compared to the risk of losing control of the car on the road.
Frequently asked questions (FAQ)
How many clicks should a working handbrake on a Nissan Terrano have?
The normal number of clicks is from 2 to 4 when the lever is lifted all the way. If the lever moves above 5 clicks, adjustment is required.
Is it possible to adjust the handbrake without removing the interior?
In most cases, the adjusting nut is accessible from underneath the vehicle, so it is not necessary to remove the tunnel trim. However, access may be difficult and removing the plastic will make the job easier.
What should I do if the wheels get hot after adjustment?
This is a sign of overtightening of the cables. It is necessary to immediately release the tension, otherwise it will lead to overheating of the brake mechanisms and brake failure.
Do I need to adjust the handbrake after replacing the rear pads?
Yes, after replacing the pads, be sure to check the cable tension, as new pads may have a different profile and the factory adjustment may not be sufficient.
How often should you check the condition of the handbrake?
It is recommended to check the operation of the handbrake every 10,000 km or during each vehicle maintenance in order to notice changes in the operation of the mechanism in time.
