Rear brake pads on Ε KODA Octavia Tour β a consumable that requires attention every 40β60 thousand kilometers. But the actual service life depends on driving style, quality of materials and operating conditions. If you notice squeaking, vibration when braking, or increased pedal travel, it's time to check the condition of the brake system. In this article we will look at how to replace the rear pads yourself, without resorting to the services of a service station, saving up to 5 thousand rubles.
Feature Octavia Tour (especially models with engines 1.6 MPI, 1.8 TSI and 2.0 TDI) - use of drum or disc brakes depending on the configuration. We will focus on disc mechanisms since they are more common. If you have a drum system, the principles are similar, but there are nuances with adjusting the handbrake. We will mention them separately.
When to change rear pads: 5 signs of wear
The manufacturer recommends checking the brake pads every 15 thousand km, but real signs of wear may appear earlier. Here are the key signals that it's time to act:
- π Creaking or whistling when braking - a sign of thinning of the friction layer. On the blocks Ε KODA Wear indicators (metal plates) are often installed that make a sound when the condition is critical.
- π Increased braking distance. If the car takes longer to stop, even in dry road conditions, the pads could become oily or worn down to metal.
- π₯ Vibration on the pedal or beating in the steering wheel. Most often associated with a warped brake disc, but sometimes the pads are also to blame - especially if they are of poor quality or installed incorrectly.
- π Brake light came on on the dashboard. On Octavia Tour this can be either a signal of a low brake fluid level or critical wear of the pads (if sensors are installed).
- π Visual wear. When viewed through the wheel spokes, it is clear that the thickness of the friction layer is less than 3β4 mm. The norm for new pads is 10β12 mm.
β οΈ Attention: If deep grooves, cracks or signs of overheating (blue metal) appear on the pads, they must be replaced immediately. Driving with such defects can lead to jamming of the caliper or destruction of the brake disc.
- Every 10 thousand km
- Only when symptoms appear
- Once a year
- Never checked
Which pads to choose: original vs analogues
For Ε KODA Octavia Tour (depending on the generation and engine) pads with original spare parts articles are suitable 1K0 698 451 (front) and 1K0 698 151 (rear). However, original parts from VW Group often 2β3 times more expensive than analogues. Alternative options:
| Brand | Article | Price (set, rub.) | Features |
|---|---|---|---|
| TRW | GDB1446 |
2 800β3 200 | High quality friction material, minimal dust level |
| ATE | 13.0460-2806.2 |
3 000β3 500 | Optimal price/quality balance, suitable for aggressive driving style |
| Brembo | P 24 060 |
4 200β4 800 | Sports series, increased wear resistance, but may creak during the first 200 km |
| Bosch | 0 986 494 219 |
2 500β2 900 | Budget option, suitable for a quiet ride |
πΉ Important: When purchasing, check compatibility with your modification Octavia Tour. For example, for versions with ESC (electronic stability system) may require pads with wear sensors. Also pay attention to friction material composition:
- π’ Ceramic - durable, low dust, but more expensive and less effective at low temperatures.
- π‘ Semi-metallic β the optimal choice for most drivers; they work well in any conditions.
- π΄ Organic - soft, wear out quickly, but brake discs are gentle.
On Octavia Tour 2015β2020 with engines 1.4 TSI and 2.0 TDI Pads with integrated wear sensors are often installed. If you buy analogues without sensors, you will have to transfer them from the old pads or buy them separately (article number 1K0 945 601).
Tools and preparation for replacement
To work you will need:
- π§ Jack and stops (or βgoatsβ) for lifting the machine.
- π© Balloon wrench for removing wheels.
- π οΈ Socket set (especially at 13, 15 and 17 mm).
- π¨ Hammer and flat blade screwdriver for working with the caliper.
- 𧴠WD-40 or similar penetrating lubricant.
- π§° Caliper Guide Lubricant (for example, Slipkote 220-R DBC).
- π©Ή DOT-4 brake fluid (in case of bleeding the system).
- π Vernier caliper for measuring the thickness of disks.
πΉ Vehicle preparation:
- Park the car on a level surface, engage first gear (or
Pfor automatic transmission) and place chocks under the front wheels. - Loosen the rear wheel bolts while the vehicle is on the ground.
- Raise the rear section with a jack and place it on supports. Never work under a machine that is supported only by a jack!
- Remove the wheel and clean the caliper and disc from dirt with a wire brush.

β οΈ Attention: If the brake fluid level in the reservoir is at its maximum, pump out some of it with a syringe before replacing the pads. When installing new (thicker) pads, the caliper piston will sink and the fluid may overflow.
Step-by-step instructions for replacing rear pads
Replacement process Octavia Tour with rear disc brakes involves several key steps. Follow the instructions strictly in order:
1. Removing the caliper
The caliper is secured with two bolts from the rear. They need to be unscrewed with a 13 or 15 mm socket (depending on the year of manufacture). Pre-treat the bolts WD-40if they are sour. After removing the caliper, hang it on a wire or rope to the spring - Do not let it hang on the brake hose!
2. Removing old pads
The pads are held in place by spring clips or guides. Carefully pry them off with a screwdriver and pull them out. Inspect the condition of the brake disc: if it has deep grooves (more than 1 mm) or waviness, the disc needs to be sharpened or replaced. Normal disc thickness for Octavia Tour β 10β12 mm (minimum acceptable β 8 mm).
3. Recessing the caliper piston
This is the most critical stage. On the rear calipers Ε KODA the piston must not only be pressed in, but turn clockwise with a special tool (or pliers). The fact is that the handbrake mechanism is built into the piston, and simply pressing it in can damage it. If the piston does not turn, treat it WD-40 and try again.
What to do if the piston does not recess?
If the piston is stuck, try the following steps:
1. Check whether the handbrake is fully released.
2. Unscrew the cap of the brake fluid reservoir - this will relieve pressure in the system.
3. Use a special caliper puller (for example, Lisle 25800).
4. If all else fails, the caliper may need repair or replacement.
4. Installing new pads
Before installation, apply a thin layer copper grease on the metal parts of the pads (except for the friction surface!). This will prevent squeaking and corrosion. Reinstall the pads in reverse order, making sure the spring clips are in place. Also lubricate the caliper guides with special grease (do not use Litol or Solid oil - they cannot withstand high temperatures!).
5. Assembly and testing
Secure the caliper with bolts (tightening torque: 30β35 Nm). Install the wheel and lower the car. Press the brake pedal several times to move the piston. Then check the operation of the handbrake: it should hold the car on a slope of 20β25% (you can test it on an overpass).
After replacing the pads, avoid sharp braking for the first 200β300 km - the new pads should get used to the discs.
Adjusting the handbrake after replacing the pads
On Octavia Tour with rear disc brakes, the handbrake is adjusted automatically when the caliper piston is retracted. However, if after replacing the pads the handbrake does not hold or rises too tightly, additional adjustment will be required. Here's how to do it:
- Raise the handbrake lever 2β3 clicks.
- Loosen the locknut on the cable equalizer (located under the machine, near the rear beam).
- Tighten the adjusting nut until the rear wheels lock.
- Lower the lever and check that the wheels rotate freely.
- Repeat the process if necessary, then tighten the locknut.
πΉ Signs of incorrect adjustment:
- π« The handbrake does not hold on a slope.
- π₯ The wheels are locked when the lever is raised 1β2 clicks.
- π The handbrake does not return to its original position.
β οΈ Attention: If after adjustment the handbrake still does not work correctly, check the condition of the cables. On Octavia Tour they often rust or sour, especially in regions with salty roads. Replacing the handbrake cable is a labor-intensive procedure that requires removing the heat shield and partially the muffler.
Common mistakes and how to avoid them
Even experienced car owners sometimes make mistakes when replacing rear pads. Here are the most common ones and ways to prevent them:
- π§ Incorrect piston retraction. If you simply press the piston in without scrolling, you can damage the handbrake mechanism. Always use a special tool or pliers to rotate.
- 𧴠Using the wrong lubricant. The lubricant for the guides must be heat-resistant (withstand up to 300°C). Conventional type lubricants Litola When heated, they flow and can get on the friction surfaces.
- π οΈ Incorrect bolt tightening torque. Overtightened caliper bolts can deform the caliper body, and loose tightening will lead to vibrations. The optimal torque is 30β35 Nm.
- π Forgetting to check the brake fluid. After replacing the pads, the level in the reservoir will rise. If it is not controlled, the fluid may overflow when heated, which will lead to loss of brakes.
- π₯ Ignores breaking in new pads. In the first 100β200 km after replacement, avoid sudden braking. The pads need time to rub evenly onto the disc.
If a squeak appears after replacing the pads, apply to the back of the pads anti-squeak paste (for example, ATE Plastilube). This will eliminate vibrations and extend the life of parts.
Cost of service replacement vs self-repair
Cost of replacing rear brake pads Ε KODA Octavia Tour in service depends on the region and level of the service station. On average the prices are:
| Service type | Cost of work (rub.) | Cost of spare parts (RUB) | Total (RUB) |
|---|---|---|---|
| Official dealer | 3 500β5 000 | 4,000β6,000 (original) | 7 500β11 000 |
| Unofficial service | 1 500β2 500 | 2,500β4,000 (analogues) | 4 000β6 500 |
| Self-replacement | 0 | 2 500β4 000 | 2 500β4 000 |
πΉ Savings: If you replace it yourself, you will save up to 70% of the cost. However, keep in mind that the work will require at least 2-3 hours of time and a set of tools. If you do not have experience, it is better to contact a service center - errors when working with the brake system can be expensive.
π‘ Tip: If you decide to change the pads yourself, at the same time check the condition of the brake discs, caliper boots and hoses. On Octavia Tour after 100 thousand km, the guide boots often wear out, which leads to corrosion and jamming of the caliper.
FAQ: Answers to frequently asked questions
Is it possible to change the pads on only one wheel?
No, the pads are always replaced in pairs on the same axis. If you replace only one side, the braking force will be distributed unevenly, which will lead to skidding and accelerated wear of the discs.
How long do rear pads last on an Octavia Tour?
The service life depends on the driving style and the quality of the pads. On average:
- Original or premium analogues (ATE, TRW) - 50β70 thousand km.
- Budget analogues (Bosch, Ferodo) - 30β50 thousand km.
- With aggressive driving or frequent braking (for example, in the city), wear accelerates by 20β30%.
Do I need to bleed the brakes after replacing the pads?
Typically, bleeding is not required as the system remains sealed. However, if you accidentally opened the air bleeder or the brake fluid has not been changed for a long time (more than 2 years), it is worth bleeding. On Octavia Tour You can do this yourself with the help of a partner or a vacuum pump.
Why did the brake pedal become soft after replacing the pads?
Probable reasons:
- Air has entered the system (the brakes need to be bled).
- The pads or caliper are not installed correctly (check the clearances).
- The brake hoses are worn out (they can swell when you press the pedal).
- Low brake fluid level or leakage.
If the problem persists, contact the service for diagnostics.
Is it possible to drive if only the outer pads are worn out?
No, this is a sign caliper jamming. In this case, the outer pad wears out faster, while the inner one remains almost new. It is necessary to remove the caliper, clean the guides, lubricate them and check the operation of the piston. If the problem persists, the caliper requires repair or replacement.
