Timely replacing brake pads This prevents expensive repairs of calipers and discs. Many car owners find this procedure too complicated to perform on their own, but with the right tool and understanding of the technology, things get much easier. In this article, we will discuss all the stages of work so that you can save on the service.
Signs of wear and when it's time to change your pads
Understand that Skoda Octavia Tour needs service, can be on a number of characteristic signs. The most obvious of them is a specific metal grinding when pressing the brake pedal. This sound occurs when the main working layer is erased and the pad metal begins to touch the disc.
In addition to the sound, pay attention to the behavior of the car when braking. If the car starts to move aside and the pedal becomes less responsive, this is an alarming signal. It is also worth checking the thickness of the friction lining visually through the caliper window or by removing the wheel.
- ๐ The appearance of a screech or grinding with a light press on the pedal
- ๐ Car pulls to the side during emergency braking
- ๐ Increased braking distance on dry asphalt
It is important not to ignore the control lamps on the dashboard. On modern modifications Octavia Tour Wear sensor is installed, which lights up when it reaches a critical level. If the lamp caught fire, you can not postpone the screeching in the service or purchase of spare parts for a day.
โ ๏ธ Attention: Ignoring the brake creak can lead to the destruction of the brake disc, which entails the need to replace it, and this is much more expensive than buying new pads.
Necessary tools and preparation for work
For a quality replacement of brake pads you will need a standard set of tools, which is in the garage of most motorists. However, the specifics of the design of the calipers Skoda Octavia Tour It requires special devices to press the piston.
You will definitely need a jack and reliable stands, as it is strictly forbidden to work under a raised car without insurance. Do not forget about a set of heads, collars and a dynamometer key for the correct tightening of the bolts.
- ๐ง Set of heads (13, 17, 19 mm depending on the caliper model)
- ๐จ Hammer and mounting for removing jammed elements
- ๐จ Compressed air or brake cleaner canister
Pay special attention to the tool for compressing the piston caliper. If you change the rear pads, the piston must not only be pressed, but also twisted. This is done by using a special key or adapter. Normal strubbin here will not work, as you can damage the mechanism.
โ ๏ธ Note: Use only a specialized tool to compress the rear caliper piston, as the mechanism has a threaded design that requires simultaneous pressing and rotation.

- Premium brands (Brembo, TRW)
- Budget analogues

Step-by-step instructions: replacing front pads
The first stage of work is the removal of the wheel and the dismantling of the caliper. Unscrew the guide calipers, which are usually on top and bottom. Be careful not to damage the brake hose when you take the caliper aside.
Next, we need to remove the old pads. Often they stick to a brace, so light tapping through the wood with a hammer may be required. Clean the caliper bracket from dust and dirt using brake cleanerApply special lubrication to the contact area.
- ๐ฉ Relax the wheel bolts on the standing car
- ๐๏ธ Lift the car with a jack and put it on a stand
- ๐ฉ Completely unscrew the bolts and remove the wheel
Return the caliper to place, having previously squeezed the piston into the cylinder. This should be done smoothly, controlling the level of brake fluid in the tank so that it does not overflow over the edge. Twirl the guide calipers with the moment specified in the technical documentation.

Features of replacing rear pads
Rear brake system Skoda Octavia Tour It has its own design features associated with the parking brake mechanism. The piston of the rear caliper does not just move linearly, it is screwed inwards using a special mechanism.
If you try to push the piston without scrolling, you break the mechanism. To do this, you need to use an adapter that is inserted into the slots of the piston, and turn it clockwise, simultaneously pressing.
- ๐ง Use a specialized key to compress the piston
- ๐ Turn the piston clockwise when pressed
- ๐งผ Check the condition of the guide and rubber covers
After installing new pads, be sure to check the handbrake. The piston must be completely recessed, otherwise the pads will constantly rub against the disc, causing overheating and increased fuel consumption.
What to do if the piston is not screwed in?
If the piston is jammed, do not use excessive force. Try moistening the thread with penetrating lubricant and wait a few minutes. In extreme cases, it may be necessary to disassemble the mechanism of the caliper, which is better to entrust to professionals.
Choosing quality spare parts and sensors
When choosing brake pads for Skoda Octavia Tour It is important not to chase the lowest price. Cheap analogues often have a poor-quality friction composition, which quickly wears off or, conversely, scratches the discs. The original is always a guarantee of quality, but it costs much more.
There are many proven brands, such as TRW, Brembo, ATE or Textar. These manufacturers supply parts to the conveyors of many auto giants, including the VAG concern. Their products provide an excellent balance between cost and resource.
| Brand | Type | Service life | Features |
|---|---|---|---|
| Skoda (OEM) | Original | High | Perfect compatibility |
| ATE | Premium | Very tall | Excellent braking properties |
| TRW | Original | High | Often goes to the conveyor line |
| Textar | Premium | High | Soft work, no dust. |
Don't forget to check the completeness. If your vehicle is installed wear indicatorMake sure the new shoe comes with it or purchase it separately. Ignoring this part will cause the control lamp to burn even after replacement.
Choosing proven brands like ATE or TRW is often a better choice than the expensive original, providing the same level of quality and reliability.
Fresh-in-the-table nuances and final checks
After installing new pads, you can not immediately go at high speed and make sharp braking. It is necessary to conduct a run-in procedure so that the friction material is tightly attached to the disk. This usually takes about 200-300 kilometers of run.
During the run-in, do several smooth braking with moderate intensity. This will allow the surface of the pads and discs to become smooth and provide the maximum contact spot. Avoid emergency braking during the first days of operation.
- ๐ Run in quiet mode for the first 300 km
- ๐ Avoid sudden stops and wheel locks
- ๐ Check your brake fluid levels in a week.
Before starting the movement, be sure to press the brake pedal several times to the end. This is necessary in order for the calipers pistons to come out of the passive state and press the pads against the discs. Otherwise, at the first emergency braking, the pedal may fail.
โ ๏ธ Warning: If after replacing the pad brake pedal became "soft" or fails, it is necessary to pump the brake system to remove the air that has fallen in.
Common mistakes when replacing yourself
Many beginners make mistakes that can negate all the work done. The most common problem is the wrong lubrication of the calipers guides. Use only special high-temperature lubricant, not litol or solidol, which destroy rubber anthers.
Another mistake is the pulling of the caliper mounting bolts or guides. This can cause them to break or deform the braces. Always use the dynamometer key and check the specifications for Octavia Tour.
Before installing new pads, be sure to wipe them from factory conservation lubricant using a brake cleaner to avoid oil hitting the friction lining.
The mistake is also forgetfulness when working with wear sensors. Unless you have repositioned an old sensor or connected a new wire, the system will not monitor wear in the future. Make sure the wire does not rub against the movable parts of the suspension.
FAQ: Answers to popular questions
How long do you have to wear the ล KODA Octavia Tour?
The resource of the shoe depends on the driving style and operating conditions. On average, the front pads walk 30-40 thousand km, the rear - 50-60 thousand km. Using non-original spare parts can shorten this period.
Is it possible to change only the front pads?
Yes, technically it is possible, but it is recommended to change the pads set on the axes (all front or all rear). This will ensure uniform braking and prevent distortions.
Do I need to change the brake discs when replacing the pads?
Not necessarily. If the thickness of the disc is within tolerance, and there are no deep furrows and cracks on the surface, it can be used further. However, if the disc is severely worn, its replacement is required.
What to do if the light of the wear sensor after replacement?
Check the correct connection of the sensor connector. Sometimes the wire is damaged during dismantling. Also make sure you install a pad with a sensor if the old one was disposable.
How often should you check your brake fluid?
It is recommended to check the level and condition of the brake fluid every 10-15 thousand kilometers of run. Complete replacement of the liquid should be made every 2-3 years, as it is hygroscopic and absorbs moisture.
