Many crossover owners Nissan Qashqai are faced with a situation where the parking brake lever begins to move too freely, or the car does not hold on a slope even with the handbrake fully raised. In most cases, the problem lies not in the mechanism itself, but in a stretched or torn handbrake cable. This part is a consumable item and over time loses its performance properties due to corrosion, dirt and mechanical stress.
Ignoring this malfunction can lead to serious consequences, including the car rolling away in the parking lot. Replacing the parking brake cable - a procedure that can actually be performed independently in a garage, if you have a minimum set of tools and a desire to save on service station services. In this article we will analyze in detail the diagnostics, selection of spare parts and the process of dismantling and installing new elements.
Diagnosis of faults and signs of wear
The first sign that your Nissan Qashqai Something is wrong, there is a change in the stroke of the lever. If you have to lift the handbrake 7β10 or more clicks before braking begins, then the mechanism needs adjustment or replacement. However, even after trying to adjust the tension through the nut under the dash, the problem can return very quickly. This is a sure signal that handbrake cable stretched beyond the permissible limit or the metal strands inside it are torn.
The second common problem is jamming. If the lever rises normally, but does not lower back or lowers with great force, the cable may be stuck in the sheath due to moisture and dirt. In this case, the brake pads remain pressed against the disc, which leads to overheating, destruction of the brake fluid and rapid wear of the friction linings. Parking brake should work accurately: fix the wheel when lifting and completely release it when lowering.
Sometimes the malfunction is accompanied by a characteristic metal creaking or clicking sound when the lever operates. This may indicate that the cable has broken inside and the broken part is interfering with the movement of the mechanism. In such situations cable replacement becomes an urgent need. You should not delay repairs, as driving with a jammed handbrake can lead to overheating of the wheel bearing and failure of the entire brake system.
Selection of spare parts and necessary tools
Before you get started, you need to decide what exactly you will install. There are two main options on the market: original parts from Nissan and high-quality analogues. Original handbrake cable has an article number that can be found in spare parts catalogs and guarantees ideal geometry and durability. However, its price is often overpriced, which forces car owners to look for alternatives.
Among analogues, it is worth paying attention to brands specializing in brake systems, such as TRW, ATE or Febi Bilstein. These manufacturers offer products that are not inferior in quality to the original, but are cheaper. It is important not to buy the cheapest Chinese cables without markings, as they often break after just a few months of use. The quality of the steel and the quality of the shell are critical to the reliability of the parking brake.
To carry out the work, you will need a standard set of tools, which almost every car enthusiast has. You don't need specialized machines, all you need is keys and heads. Below is a list of what you need:
- π§ Socket set (including 10, 12 and 14 mm sizes)
- π§ Extension and wrench for access to hard-to-reach places
- π§ Pliers and screwdrivers for removing fasteners
- π§ WD-40 or similar penetrating lubricant for loosening rusty bolts
Also, do not forget to prepare a jack and reliable stands for the car. Security when working with a raised vehicle, this is priority number one. Never work under a machine supported solely by a jack. Make sure Nissan Qashqai stands on a flat surface and is securely fixed.
Step-by-step instructions for replacing the cable
The replacement process begins with preparing the car. Raise the rear of the car with a jack, remove the wheels and install stands. The first thing you need to do is get to the tension mechanism, which is located in the cabin, under the center console. Remove the bezel surrounding the handbrake lever to gain access to the adjusting nut and locknut.
Next, you need to loosen the tension on the cable. To do this, unscrew the locknut and the adjusting nut itself so that the cable is completely slack. This will make subsequent dismantling easier. After that, move on to the wheel arch. Remove the brake rotor and caliper to gain full access to the brake pad lever on the rear brake mechanism. Here the cable connects to the rocker arm.
Removing the cable from the reverse side requires care. Disconnect the cable end from the brake pad lever. This finger can often get stuck, so use a penetrating lubricant and tap it gently. Then you need to unscrew the brackets securing the cable to the car body. There are usually two or three depending on the model year. After this, the cable can be pulled out of the cabin, carefully passing through all the guides.
- π οΈ Disconnect the cable end from the rear brake lever
- π οΈ Unscrew the bolts securing the cable to the body and shield
- π οΈ Carefully pull the cable through the interior without damaging the trim
- π οΈ Remove the old cable from the mounts under the hood (if any)
Installing a new cable is done in the reverse order. Pull it through the interior and secure it in the brackets. It is important not to confuse the left and right cables if they are sold separately, as they may differ in length and tip shape. Connect the end piece to the brake lever, making sure it is secured securely.
β οΈ Attention! When installing a new cable, make sure that it is not twisted or has no tension when free. A twisted cable will quickly fail and become jammed.
βοΈ Preparation for replacement
The nuances of working with the rear caliper
When removing the caliper, it is important not to let it hang on the brake hose. Use a wire or hook to hang it from the shock absorber spring. Also, if you have rear disc brakes with an integrated handbrake mechanism, you may need a tool to press in the caliper piston, but most often when replacing the cable, you just need to remove the caliper completely.
- Once a year
- Every 2 years
- Only in case of breakdown
- Never served
Adjustment and final check
After installing the new cable, it is critical to properly tension it. If the cable is too weak, the car will not stay in place. If too much, the brake pads will constantly rub against the disc, causing overheating and increased fuel consumption. Return to the cabin and begin tightening the adjusting nut.
You need to achieve such a tension that the handbrake lever rises 4-6 clicks. This is the standard value for Nissan Qashqai. Once the desired number of clicks has been achieved, tighten the lock nut to secure the position. Don't forget to check that the wheels rotate freely when the handbrake is lowered. The wheels should spin without resistance.
Functional testing should be carried out not only in place, but also in motion. Find a safe part of the road with a slight slope. Stop the engine, put the gear in neutral and raise the handbrake. The vehicle must be held securely in place. Also check to see if spontaneous braking occurs while driving. If you feel that the car is being pulled to the side or hear a burning smell, it means that the adjustment has not been made correctly.
β οΈ Attention! If after adjustment one of the rear wheels continues to get hot or is difficult to rotate, stop immediately. This is a sign that the cable is jammed or is overtightened. Driving in this mode may cause a fire.
Frequent mistakes and advice from experts
One of the most common mistakes when replacing is trying to tighten the cable βby eyeβ without checking the rotation of the wheels. Many owners over-tighten the nut, thinking that it will be more secure. As a result, the brake pads are constantly in contact with the disc, which leads to rapid wear and deformation of the brake disc. Wheel rotation control - a mandatory step after each adjustment.
Another mistake is using lubricant for other purposes. Some craftsmen try to lubricate the cable itself inside the sheath so that it moves better. This is strictly forbidden, as the lubricant may leak out and contaminate the brake pads, which will sharply reduce their effectiveness. If the cable gets stuck, it needs to be replaced, not lubricated. Use lubricant only on threaded joints and arm joints.
It is also worth paying attention to the condition of the mounting brackets. If the metal has corroded and broken down, the new cable will not hold securely. In such cases, it is recommended to replace the brackets or use special clamps to secure the cable. Ignoring the condition of the fasteners can lead to the fact that in six months you will have to crawl under the car again.
| Parameter | Original (Nissan) | Analogue (TRW/ATE) | Cheap analogues |
|---|---|---|---|
| Average price (per pair) | 8000β12000 rub. | 4000β6000 rub. | 1500β2500 rub. |
| Service life | 80,000+ km | 50,000β70,000 km | 10,000β20,000 km |
| Steel quality | High | Medium/High | Low |
| Risk of jamming | Minimum | Low | High |
Before starting work, be sure to treat all cable mounting bolts and adjuster nuts with penetrating lubricant (WD-40) and wait 10-15 minutes. This will save you a lot of time and nerves when unscrewing.
Correct adjustment of the cable tension is the key not only to safe parking, but also to the long service life of the rear brake discs and pads.
Savings and cost of repairs at service stations
Many car owners are wondering: is it worth doing the replacement themselves or is it better to contact a service center? The cost of work at a specialized service station can vary from 3,000 to 6,000 rubles for replacing the handbrake cable. This does not include the cost of the parts themselves. If you replace the cables yourself, you will save this amount by only spending time and money on buying parts.
However, if you do not have the experience, tools or working conditions (pit, lift), the risk of damaging other components or making incorrect adjustments increases. The service does the work quickly, with a guarantee of quality. Also, technicians can immediately diagnose the brake system and identify wear on pads or discs that you might not have noticed.
If you decide to go the DIY route, pay special attention to studying the wiring diagram for your specific model year. The nuances may differ depending on whether your crossover is front-wheel drive or all-wheel drive (4x4).
β οΈ Attention! All-wheel drive versions Nissan Qashqai have additional driveshafts and a coupling, which may make it difficult to access some of the fastening elements of the handbrake cables. Be careful when dismantling.
FAQ: Frequently asked questions
Is it possible to replace only one cable or do both need to be replaced?
It is recommended to replace both cables at the same time, even if one of them appears intact. Cables wear out evenly, and an old cable may break soon after one of them is replaced. In addition, when replacing one cable, you often have to completely disassemble the mechanism, which makes replacing the second one practically free in terms of labor costs.
Do I need to change the cables if the handbrake simply does not hold on a slope?
Yes, if the handbrake does not hold, this is a direct indication of a malfunction. Try adjusting the tension first. If, after adjustment, the handbrake rises all the way, but the wheel does not lock, or the adjustment does not help keep the car on a slope, the cables are stretched or torn and need to be replaced.
How long does it take to replace a handbrake cable on a Qashqai?
For an experienced technician, replacement takes about 1β1.5 hours. For a beginner doing this procedure for the first time, it may take 2-3 hours. The time depends on the degree of corrosion of the bolts and the availability of tools. Take your time, especially when unscrewing old fasteners.
What happens if you drive with a broken handbrake?
Driving with the handbrake not working is dangerous. If the main hydraulic brake fails, you will have no backup stopping system. Additionally, on steep slopes or when parking on an incline, the vehicle may roll, resulting in an accident or property damage. This is also a traffic violation.
Is it possible to lubricate the handbrake cable to make it work better?
Do not lubricate the cable inside the sheath, as this may cause grease to leak onto the brake pads and reduce their effectiveness. If the cable becomes stuck, it must be replaced. You can only lubricate the external threaded connections and levers of the handbrake mechanism, but not the cable itself.
