Adjusting the parking brake on a car Skoda Octavia Tour Rear wheel drums are a procedure that requires attention to detail and an understanding of the specifics of the design. Owners of this model often face a problem when the lever of the โhandleโ rises too high, or the brake does not keep the car on a slope. Often this is not due to wear of the cables, but to the wrong gap between the pads and the drum.
Unlike disc brakes, where the automatic adjustment mechanism works differently, in drum systems. Skoda Octavia Tour The tension of the cables should be checked and adjusted periodically. Ignoring this procedure can lead to overheating of the brake mechanisms or, conversely, to a complete absence of braking force. Proper tuning ensures safety and predictability of the vehicleโs behavior during an emergency stop.
Signs of need for adjustment and diagnostics
The first and most obvious signal that it is time to intervene in the system is the number of clicks when lifting the lever. For Skoda Octavia Tour The normal range is from 3 to 7 clicks. If the lever is raised higher, the brake pads cease to press against the drum with sufficient force.
However, the number of clicks is not the only indicator. It is necessary to pay attention to how the car behaves when moving from a place after parking. If the machine โslows downโ or emits a characteristic grinding, this indicates that the gap is too small or the mechanism is jammed. It is also worth checking if the rear wheels are overheating after the trip.
- ๐ The lever rises above 8-9 clicks without any noticeable resistance.
- ๐ The car rolls on a slope with a tight hand.
- ๐ก๏ธ The rear wheels get very warm after a short ride.
- ๐ง Uneven tightening of the lever (one cable is stretched, the other sagged).
It is important to understand that the problem may lie not only in the cable drive. Often the cause is wear of the brake linings themselves or jamming of the mechanism of the detachment of the pads inside the drum. Therefore, before starting to adjust the cables, it is necessary to make sure that the mechanisms are serviceable.
โ ๏ธ Warning: Before starting any work, make sure that the car is on a flat surface and the front wheels are securely fixed with recoil stops. Donโt rely on the gearbox or handbrake alone when lifting the car onto the jack.
Preparation of tools and workplace
For quality work you will need a standard set of tools that most motorists have. Pay special attention to the keys for unscrewing the bolts of drum attachment and adjustment tools. Without the right inventory, the process can drag on or damage the thread.
You will need end keys and heads of 13, 15 and 17 mm. To access the tension mechanism of the cables will require a long rattle and extension cords. Also, do not forget about lubrication, as threaded joints on the suspension are often subjected to corrosion and dirt.
- ๐ ๏ธ A set of end heads and a rattle with extension cords.
- ๐จ Hammer and mount to remove jammed drums.
- ๐ง WD-40 liquid or analogue for thread processing.
- ๐งผ Cloths and a metal brush to clean the machinery.
The workplace should be well lit. If you work in a garage, take care of a portable lamp. Examine the rear of the car from below to assess the condition of the protective screens and the integrity of the cables themselves. If the cable has visible damage to the braid, its replacement is mandatory.
โ๏ธ Necessary tool
Removing the drum and inspecting the mechanism
Removal of the back drum Skoda Octavia Tour It may require some effort, since the wear of the linings often leads to the fact that the drum โgrowsโ to the hub. Do not try to shoot it with your bare hands or with a hammer on the drum itself - this can lead to its cracks.
The first thing to do is to remove the brake caliper. If you have a version with a drum brake, the caliper is absent, but you need to remove the brake disc if it is part of the design, or immediately go to the drum. On many modifications Octavia Tour The drum is put on the hub and is fastened by a screw. This screw is often fixed by a thread fixer.
After unscrewing the fastener, if the drum does not come down, try to gently tap it with a rubber kiyayan from the inside. In extreme cases, you can use the installation, putting the drum behind the technological holes, but do it very carefully so as not to damage the brake tubes.
- ๐ฉ Unscrew the drum mount bolt (often a Torx key is required).
- ๐จ Carefully tap the drum to knock it off the hub.
- ๐ Check the brake pads for wear.
- ๐งน Clean the mechanism of dust and dirt.
It is important to check the status of the mechanism of automatic adjustment of the gap (star and lever). If it is clogged with dirt or skeet, it will not be able to compensate for the wear of the pads during operation, and you will have to adjust the handbrake manually each time.
What to do if the drum cannot be removed?
Try pouring the connection with penetrating lubricant and wait 15-20 minutes. If it doesnโt help, you can use a skipper, but itโs best to gently heat the center of the drum (not brake pads) with a building hair dryer or blowtorch so that the metal expands.
Procedure for adjusting cable tension
After you have convinced of the serviceability of the brake mechanisms themselves, you can start adjusting the cables. This is done through a special hatch in the bottom of the car or through the wheel arch. Nana Skoda Octavia Tour Most often used adjustment nut under the bottom, next to the rear axle.
You need to loosen the counternut and rotate the adjusting nut. The spinning turns one way and the other way, weakens. Do this slowly, periodically checking the lever in the cabin. Do not pull the cables too much, otherwise the rear wheels will constantly slow down.
The ideal setting is achieved when the lever is raised by 3-5 clicks, and the wheels rotate freely when the handbarrow is lowered. You can check this by lifting the car on the jack. The wheel should rotate without resistance, but when the lever is raised by 2-3 clicks, it should lock.
- ๐ง Relax the counternut on the adjustment bolt.
- ๐ Turn the control nut to pull the cables.
- ๐ Check the lever in the cabin after each turn.
- ๐ Hold the counternut while holding the adjusting one.
If you see that the cables have different tension lengths, you need to adjust them so that they work synchronously. Often the problem is that one cable is pulled and the other sags, which leads to uneven braking.
Before tightening the counternut, apply a little graphite lubricant to the thread of the adjustment bolt. This will prevent it from jamming in the future and make it easier to re-adjust.
- 1-2 clicks
- 3-5 clicks (Norma)
- 6-8 clicks
- More than 8 clicks
Setting up the mechanism inside the drum
If the adjustment of the cables does not give a result or the handbrake tightens too easily, the problem may be in the very mechanism of the detachment of the pads inside the drum. Nana Skoda Octavia Tour a sliding bar with a regulator is used, which is driven by a lever.
You need to check how the divorce mechanism works. The lever should be freely moved and fixed in the right position. If the mechanism is jammed, it must be disassembled, cleaned and lubricated. Also check the condition of the return springs โ they should not be stretched or broken.
A special star regulator is used to adjust the gap inside the drum. It can be scrolled with a screwdriver through the technology window in the brake shield. The sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the sliding of the s. This allows you to adjust the gap accurately.
- ๐ Check the free movement of the lever inside the mechanism.
- ๐งฝ Clean all moving parts of old lubricant and dust.
- ๐ข๏ธ Grease the axles of the levers and the squeezing bar with heat-resistant lubrication.
- ๐ง Adjust the gap through the window in the brake shield.
It is important not to overdo it with the sliding of the pads. If the gap is too small, the pads will rub against the drum when moving, causing overheating and rapid wear. The optimum clearance should be 0.2-0.3 mm, which ensures the absence of friction with free rotation of the wheel.
Table of parameters and tolerances
For accurate configuration, it is useful to check with technical data. Below is a table with the main parameters characteristic of the model Skoda Octavia Tour with drum brakes. These values will help you to understand whether your indicators are normal.
| Parameter | Meaning | Note |
|---|---|---|
| Handbrake lever travel | 3-7 clicks | On full rise |
| Thickness of brake lining | min. 1.5 mm | Safe wear limit |
| Diameter of the working surface of the drum | Max. 201.0 mm | The limit of squandering |
| Moment of drum bolt tightening | 10-15 Nยทm | Depends on year of manufacture |
| Wheel bolt tightening torque | 120 Nm | Mandatory importance |
Please note that the parameters may vary slightly depending on the year of the car and the type of brake system installed. Always check the current information in the technical documentation for your car.
If you notice that the diameter of the drum exceeds the permissible limit, it must be replaced. Drumming the drum above normal will lead to its destruction when heated. It is also important to monitor the condition of the hub - if there is a production on it, this can cause the drum to beat.
โ ๏ธ Attention: The use of drums with a diameter exceeding the permissible limit is strictly prohibited! This can cause the drum to break while driving and cause you to lose control of the vehicle.
Final check and testing
After completing all adjustment work, a thorough check must be carried out. Reinstall the drums and tighten the mounting bolts to the correct torque. Make sure all springs and retainers are installed correctly.
Lower the vehicle to the ground and test drive it. First, try stopping on a level road at different speeds, then find a slight incline and check if the car holds. The lever should be locked securely, and when released, the wheels should rotate freely.
- ๐ Test your braking on a flat road.
- โฐ๏ธ Check hill hold.
- ๐ Listen to extraneous sounds when moving.
- ๐ก๏ธ Check the tire temperature after driving.
If everything is in order, you can consider the work done. Regular inspection and maintenance of the parking brake system is key to your safety. Do not forget to check the condition of the handbrake every 10-15 thousand kilometers.
Correctly adjusting the handbrake requires balance: the pads should press firmly when braking, but not touch the drum when the wheel rotates freely.
Frequently asked questions and answers (FAQ)
Why does the handbrake on the Skoda Octavia Tour not hold even after adjustment?
This may be due to severe wear on the brake pads or drums. If the pads are worn down to metal, adjustment will not help. The cause may also be jamming of the shoe release mechanism inside the drum or damage to the cables. It is necessary to remove the drums and visually inspect the parts.
How often do you need to adjust the handbrake on this model?
It is recommended to check the lever stroke at every maintenance. If you notice that the number of clicks has increased, or the handbrake has become worse to hold, adjustments should be made immediately. Usually this is required once every 20-30 thousand kilometers, but depends on operating conditions.
Is it possible to adjust the handbrake without removing the drums?
In some cases, it is possible to adjust the tension of the cables without removing the drums, but this does not guarantee the correct operation of the mechanism. If the problem is a jammed expansion bar or severe wear of the pads, you cannot do without removing the drum. Full adjustment requires access to internal mechanisms.
What to do if the handbrake cable breaks?
If the cable breaks, it is necessary to replace it entirely or with a separate part, depending on the design. On Skoda Octavia Tour Often the entire cable assembly is replaced. After replacement, be sure to adjust the tension, since the new cable has a different stroke.
Why doesn't the rear wheel rotate after adjustment?
Most likely, you have overtightened the cables or incorrectly adjusted the gap inside the drum. The pads are pressed too hard against the drum. Loosen the adjusting nut and try adjusting the clearance again while checking the rotation of the wheel on the jack.
