Often owners Skoda Octavia A5 are faced with a situation when the parking brake lever, popularly called the βhandbrake,β rises too high. This phenomenon not only causes discomfort when parking, but also signals that the brake pads are worn out or the cables are stretched. Ignoring this problem can lead to reduced braking efficiency on slopes and increased wear of the mechanism.
The handbrake system in this model has its own design features that distinguish it from other cars in the group VAG. Correct adjustment requires care and an understanding of how the rear brakes operate. In this article we will look at how to perform this procedure yourself without resorting to the services of a car service.
Wear diagnostics and tool preparation
Before you begin to physically impact the components of the car, it is necessary to conduct a thorough diagnosis. If the lever rises above 6-8 clicks, this is a sure sign that the elements need to be adjusted or replaced. However, if the lever travel has become too large, you should not immediately grab the keys - perhaps the problem lies in the mechanism itself.
To work, you will need a standard set of tools that any car enthusiast has, but it is better to have specialized tools. Pay attention to the condition of the cables: they should not have visible damage to the braid or rust. It is important to check whether the cables move freely in the guide channels.

- π¨ Hammer and drift for removing drums
- π οΈ Screwdrivers (phillips and flathead) for removing plugs
Don't forget about personal protective equipment. The work is carried out under the car, so use reliable stands or an inspection hole. Using a jack without insurance is strictly prohibited.
Access to the adjustment unit under the bottom
The easiest way to tighten the cables without disassembling the brake mechanisms is to adjust them under the bottom of the car. On Octavia A5 this unit is located in the area of the rear beam, slightly in front of it. You need to find a protective cover made of rubber or plastic that covers the tension mechanism.
After removing the protective element, you will see a nut that secures the tension bolt. It is she who is responsible for the degree of tension of both cables at the same time. Using a wrench, you need to loosen the lock nut and turn the adjusting nut clockwise. This action shortens the cable system.
Proceed gradually: make several revolutions, then check the result. If the cables are overtightened, the rear wheels may begin to slow down even when released, which will lead to overheating of the pads and drums.
β οΈ Attention: Do not try to tighten the cables to the limit βby eyeβ. This may cause the lever to become deformed or the rear wheels to jam when driving.
After preliminary adjustment, you need to check the free play of the lever. The lever should be fixed firmly, but not too rigid. The optimal number of clicks when lifting is from 3 to 5.

Rear drum disassembly and pad replacement
If adjustments under the bottom do not give the desired result or you plan to replace worn parts, you will have to remove the rear brake drums. This is a more labor-intensive process, but it allows you to fully assess the condition of the mechanism. On Skoda Octavia A5 A situation often occurs when the drum sticks to the hub due to corrosion.
To remove the drum, you first need to remove the wheel and unscrew the guide pins. If the drum cannot be removed by hand, use special bolts screwed into the technological holes that will squeeze it out. Do not hit the edges of the drum with a hammer to avoid damaging the fragile cast iron.
Once removed you will see the brake pads and tightening mechanism. This is where the adjusting nut is located, which is responsible for tensioning the cable on one side. Pay attention to the condition of the return springs - they should not be stretched or broken.
- π οΈ Use special drum puller
- π§Ό Clean the hub from rust before installation
- π© Lubricate the guide pins with graphite grease
It is important not to confuse the left and right sides when assembling. The shoe tightening mechanism has a directional design. If you place the parts incorrectly, the handbrake may not work or may block the wheel.
βοΈ Preparing to disassemble the brake assembly
What to do if the drum cannot be removed?
Use two M8 bolts, screwing them into the special holes on the drum. By tightening them alternately, you will create a force that will push the drum out of the hub. Do not try to rip it off by force, as this may damage the part.
Adjusting the tension of the cables inside the mechanism
Inside the drum, at the rear end of the cable, there is a special locking nut. It allows you to adjust the cable tension individually for each wheel. This must be done if one of the cables is weaker than the other. The process requires patience and precision.
Loosen the locknut and rotate the adjusting nut. You need to achieve a position so that the pads are pressed tightly against the drum, but do not create friction when the wheel rotates. After adjustment, be sure to tighten the locknut so that the clamp does not move during operation.
Don't forget to check the operation of the pad spreading mechanism. It should work clearly and without jamming. If the mechanism is soured, it must be cleaned and lubricated with a special high-temperature lubricant.
β οΈ Caution: When making adjustments inside the drum, make sure the springs return the shoes to their original position. Otherwise, the handbrake will not release after stopping.
If you are using new cables, their tension should be a little stronger, since they will βsitβ a little more during use. Old cables, on the other hand, may become permanently deformed and require replacement.
- π§ Use a torque wrench to tighten
- π Check the integrity of the cable boots
- π οΈ Apply lubricant to threaded connections
Before starting adjustment work, take a photo of the location of the springs and levers. This will help you reassemble the mechanism correctly if parts fall apart.
Checking the result and test drive
After completing all adjustment work, a thorough check must be carried out. Place the car on a flat surface and try to lift the handbrake lever. It should lock in place with 3-5 clicks. If the lever lifts too easily or too tightly, the procedure must be repeated.
An important step is to check for the absence of self-unlocking. The wheels should rotate freely when the lever is lowered. If you feel resistance or hear a grinding noise, the cables are overtightened. This is dangerous due to overheating of the brakes and fire.
Before driving, make sure that the handbrake indicator on the instrument panel goes out when the lever is lowered. If the light is constantly on, check the limit switch under the lever.
| Parameter | Norm | Deviation | Action |
|---|---|---|---|
| Number of clicks | 3-5 | More than 6 | Tighten the cables |
| Free wheel movement | Full | There is friction | Release the tension |
| Uniformity of braking | Same | Skew | Adjustment of each cable |
| Indicator operation | goes out | Lit | Check limit switch |
After a visual inspection, it is recommended to take a short test drive. Choose a safe section of the road with a slight slope. Try stopping on a hill using only the handbrake. The vehicle must be held securely.
If after the test you notice that the handbrake has released, it means that the adjustment was not done well enough. In this case, you need to return to the adjusting nuts and repeat the process.
A properly adjusted handbrake should hold the car on a slope of 15-20 degrees without slipping and operate within 3-5 clicks of the lever.
Frequent errors during adjustment
Many car enthusiasts make typical mistakes when trying to tighten the parking brake themselves. One of the most common is excessive tension. In pursuit of rigidity of fixation, drivers overtighten the cables, which leads to rapid wear of the pads and drums.
Another mistake is ignoring the state of the guides. Even a perfectly tensioned cable will not work if it gets stuck in the boot or guide channel. Regular cleaning and lubrication of cables will extend their service life.
It is also worth noting the problem with incorrect assembly of the mechanism. If the springs are installed skewed or out of place, the handbrake may not work at all. Always check the assembly diagram or take a photo before disassembling.
- β Pulling cables until they jam
- β Ignoring guide contamination
- β Using the wrong lubricant
Don't forget that on some models Octavia A5 There is an electronic control system that can generate errors if the parameters deviate greatly. In such cases, computer diagnostics may be required.
If you doubt your abilities or do not have the necessary tools, it is better to entrust this work to professionals. Incorrect adjustment can cost you your safety on the road.
β οΈ Attention: Be sure to replace the lock washers and bolts with new ones when reassembling, as the old ones may not provide the necessary retention.
Regular inspection and maintenance of the handbrake system is key to your safety. Do not put off repairs until later if you notice that the lever has begun to rise too high. A simple adjustment can prevent serious problems in the future.
FAQ: Frequently asked questions
How many clicks should the handbrake on an Octavia A5 have?
The optimal number of clicks when raising the lever is from 3 to 5. If the lever rises above 6-7 clicks, adjustment or replacement of the cables is required.
Is it possible to tighten the handbrake without removing the wheels?
Yes, you can adjust the tension of the cables through the hatch under the bottom of the car without removing the wheels and drums. However, this is a less accurate method.
Why doesn't the handbrake keep the car on a slope?
The cause may be worn pads, stretched cables or dirty guides. It is also possible that the brake pad braking mechanism is jammed.
How often should the handbrake be adjusted?
It is recommended that adjustment be carried out every time the brake pads are replaced or when there is a noticeable increase in the lever stroke. Usually this happens once every 30-50 thousand kilometers.
Do I need to change the cables during adjustment?
If the cables have visible damage, severe corrosion or binding, they must be replaced. Adjustment will not restore their functionality in this case.
