Brake system ล KODA Octavia A7 (including restyled versions 2017โ2020) is a complex mechanism on which not only driving comfort, but also safety depends. Brake discs, along with the pads, bear the brunt of the load when decelerating, and their condition requires special attention. In this article we will look at all the nuances of selecting wheels for Octavia A7: from original articles to premium analogues, we will consider signs of critical wear and give step-by-step instructions for replacement, taking into account typical errors.
Feature Octavia A7 โ a variety of engines and trim levels, which affects the size of the brake discs. For example, versions with motors 1.4 TSI (140 hp) and 2.0 TDI (150 hp) are equipped with discs with a diameter 288 mm in front, whereas for RS versions with 2.0 TSI (220/230 hp) enlarged wheels are provided 340 mm. Dimensions that do not match can lead to incorrect ABS operation and accelerated pad wear. Therefore, the first step is to accurately determine the modification of your car.

โ ๏ธ Attention: Discs for Octavia A7 with the system ABS and ESC have special grooves for sensors. Installing โblindโ disks without grooves will lead to errors in the operation of the electronics. Also note minimum permissible thickness - it is indicated on the end of the disk (for example, MIN TH=20 mm). The use of discs thinner than this value is strictly prohibited.
The cost of original discs varies from 8,000 to 25,000 rubles per couple (depending on modification). However, many owners prefer analogues from trusted brands, which often surpass the original in terms of service life. More on this in the next section.

The best analog brake discs for Octavia A7: comparison of brands
The market offers dozens of disk options for Octavia A7, but not all meet safety requirements. We analyzed owner reviews and tests from independent laboratories (for example, ADAC) to make a rating of reliable analogues. The selection criteria were: OEM sizing, resistance to deformation and resource for aggressive driving.
- ๐ฅ Brembo (series UV Coated) is the best choice for Octavia RS. Disks with corrosion protection and increased heat transfer. Article number for front axle:
09.9662.11(340 mm). Average price: RUB 18,000/pair. - ๐ฅ ATE (series PowerDisc) - the optimal combination of price and quality. Suitable for most modifications. Article:
24.0122-0179.2(288 mm). Price: RUB 12,000/pair. - ๐ฅ TRW (series DF4720) is the original supplier for VAG. Article:
DF4720(312 mm). Price: RUB 14,000/pair. - ๐ฐ Textar - a budget option with good reviews. Article:
92101900(288 mm). Price: RUB 7,500/pair. - โ ๏ธ Ferodo (series Premier) - suitable for quiet driving, but prone to overheating with frequent braking. Article:
DDF1337(312 mm).
๐น Important nuance: For Octavia A7 with the system Start/Stop discs with anti-corrosion coating (for example, Brembo UV Coated or ATE PowerDisc). This is due to frequent short trips, during which the discs do not have time to dry, which accelerates the formation of rust.
If you choose between perforated and ventilated disks, please note:
- ๐ Ventilated (with internal channels) - optimal for city driving. They dissipate heat better, but are sensitive to aggressive driving styles.
- โก Perforated - Suitable for sporty driving (e.g. Octavia RS). They cool faster, but are prone to cracks with frequent temperature changes.
- ๐ก๏ธ Slotted (with grooves) - a compromise option. They improve grip on the pads, but wear them out faster.
When purchasing discs, check for a certificate ECE R90 is a guarantee of compliance with European safety standards. Lack of markings may mean counterfeit or low-quality products.
Signs of Brake Disc Wear: When to Replace
Manufacturer ล KODA recommends checking the condition of the brake discs every 30,000 km or when replacing pads. However, actual service life depends on driving style, quality of materials and operating conditions. Here key symptomsindicating the need for replacement:
- ๐จ Vibration on the steering wheel or brake pedal when slowing down - a sign disc deformation (beating). It often occurs after a sharp cooling of a hot disk (for example, driving through a puddle after heavy braking).
- ๐ Creaking or grinding when braking - may indicate critical wear (disc thickness below minimum) or foreign particles getting between the pad and disc.
- ๐ Visible furrows or steps on the working surface - a consequence of uneven wear or the use of low-quality pads.
- ๐ฅ Overheating disks (determined by the blue tint of the metal) - indicates insufficient ventilation or a jammed caliper.
- ๐ Car withdrawal to the side when braking - possible uneven output discs or hub damage.
โ ๏ธ Attention: On Octavia A7 with the system ESP worn discs can cause ABS false alarms, especially on wet roads. This is due to a change in the geometry of the disk, which confuses the sensor readings. If the icon lights up on the dashboard ABS/ESP, first of all, check the brake discs!
The critical thickness of rims for the Octavia A7 is 20โ22 mm (depending on modification). Exceeding this threshold even by 1 mm increases the risk of the disk cracking when heated.
How to measure the thickness of a rim without removing the wheel?
Use a caliper with extended jaws (e.g. Mitutoyo 500-196-20). Measure the thickness at 3-4 points around the circumference. A difference of more than 0.03 mm between measurements indicates deformation.
Step-by-step instructions for replacing brake discs on an Octavia A7
Replacing disks with Octavia A7 does not require specialized equipment, but will require accuracy and consistency. Work is carried out on lift or inspection hole using a jack and stops. Below is a step-by-step algorithm for the front axle (the rear axle is replaced in the same way, but a drum puller may be required on versions with a hand brake).
Allow the rims to cool (at least 2 hours after driving)|Jack up the car and remove the wheel|Clean the caliper and guides from dirt (use WD-40)|Prepare new discs and pads (it is recommended to change them at the same time)|Check the availability of the caliper repair kit (boots, grease for guides)-->
Required tools:
- ๐ง Socket set (
T30,T45,13 mm,17 mm). - ๐จ Hammer (for carefully removing the disc from the hub).
- ๐ฉ Caliper puller (eg Hazet 4972-1).
- ๐งด Caliper Lubricant (Slipkote 220-R DBC).
- ๐ Vernier calipers (to check the runout of the new disc).
Procedure:
- Removing the caliper:
Unscrew the two bolts securing the caliper to the bracket (usually
T45). Hang the caliper on a wire to avoid damaging the brake hose. Do not disconnect the hose! - Removing the old disk:
If the disk is โstuckโ to the hub, gently tap it with a hammer through a wooden spacer. Do not hit the work surface! On Octavia A7 disks with mounting screws - they need to be unscrewed with a screwdriver
T30. - Installing a new disk:
Clean the hub from rust and apply a thin layer copper grease to the seat. Install the disk and secure it with screws (tightening torque - 8 Nm).
- Reassembly:
Install new pads, lubricate the caliper guides and reassemble everything in reverse order. After replacement press the brake pedal several timesso that the pads are in working position.
โ ๏ธ Attention: On Octavia A7 with electronic hand brake (EPB) after replacing disks is required adaptation reset via a diagnostic scanner (for example, VCDS or OBDeleven). Otherwise, the brake may operate spontaneously. Command to reset to VCDS:
Block 53 (Parking Brake) โ Basic settings โ Channel 01 โ Enter 18000After replacing the discs, avoid sharp braking for the first 200 km - the pads need time to break in to the new surface.
Common mistakes when replacing disks and how to avoid them
Even experienced technicians sometimes make mistakes that lead to premature wear of the discs or incorrect operation of the brake system. Here most common slip-ups and ways to prevent them:
- ๐ง Using old pads with new discs - leads to uneven wear. The pads must be new, even if their service life seems sufficient.
- ๐งด Lack of lubrication on the caliper guides โ causes wedging and uneven fit of the pads. Use only specialized lubricants (for example, Slipkote or TRW PFG110).
- ๐ฉ Retightening the caliper mounting bolts - the tightening torque should be 30 Nm for the front axle and 25 Nm for the back. Exceeding this leads to deformation of the bracket.
- ๐ Failure to check disk runout after installation โ permissible runout for Octavia A7 no more 0.05 mm. Exceeding the value will cause vibrations.
- ๐ฅ Ignoring hub cleaning - rust or dirt on the seating surface will lead to disc misalignment and its premature wear.
๐น Expert advice: If the brake pedal becomes soft after replacing the discs, bleed the brake system. On Octavia A7 with ABS This will require a scanner, since the block ABS you need to switch to pumping mode with the command:
Block 03 (ABS) โ Basic settings โ Canal 001 โ Turn on pump (10 seconds)Cost comparison: original vs analogues vs service station
Price for replacing brake discs Octavia A7 depends on the selected spare parts and installation method. Below is a comparative table of costs for the front axle (prices are valid for 2026 for Moscow and the regions).
| Option | Cost of spare parts (RUB) | Cost of work (rub.) | Total (RUB) | Warranty |
|---|---|---|---|---|
| Original discs + pads (VAG) | 22 000 | 3 500 (service station) | 25 500 | 12 months |
| Premium analogues (Brembo + ATE) | 18 000 | 3 500 (service station) | 21 500 | 24 months |
| Budget analogues (Textar + Ferodo) | 10 000 | 3 500 (service station) | 13 500 | 6 months |
| Self-replacement (Brembo) | 18 000 | 0 | 18 000 | Depends on the store |
๐ก Savings without loss of quality: If your budget is limited, you can save on labor by doing the replacement yourself, but don't skimp on pads. Cheap friction materials (for example, no-name from China) can damage new wheels within 5,000 km. The best option is pads ATE or Brembo (about 4,000 rub./set).
โ ๏ธ Attention: On Octavia A7 with the system Start/Stop It is not recommended to install drives from budget brands (for example, AvtoVAZ or Pilenga). Their coating quickly corrodes due to frequent contact with moisture, which leads to caliper jamming.
Frequently asked questions (FAQ)
Is it possible to install perforated wheels on a regular Octavia A7 (not RS)?
Technically yes, but it's impractical. Perforated rims are designed for high loads (for example, track days or mountain serpentines). In the urban cycle, they wear out faster and require more frequent pad replacement. For standard Octavia A7 premium ventilated discs (e.g. ATE PowerDisc).
How often do you need to change brake discs on an Octavia A7?
Average resource of original disks - 80,000โ120,000 km. However, with aggressive driving or frequent trips on mountain roads, wear may occur within 50,000 km. Check the thickness of the rims every 15,000 km. Critical wear - when the thickness approaches the minimum value indicated on the end of the disk (usually 20โ22 mm).
What happens if you don't change discs with grooves?
Grooves on the discs reduce the contact area with the pads, which leads to:
- โ ๏ธ Increased braking distance by 15โ30%.
- ๐ฅ Overheating of the brake fluid and the risk of boiling (especially on Octavia RS).
- ๐ Uneven pad wear and vibrations during braking.
In critical cases, the disk may split apart during sudden braking, which leads to a complete loss of brakes on one of the wheels.
Do I need to bleed the brakes after replacing the discs?
Bleeding is required only in two cases:
- If you have disconnected the brake hoses from the caliper.
- If the brake pedal becomes โwobblyโ after replacement (this indicates air has entered the system).
On Octavia A7 with ABS It is better to entrust pumping to specialists, since a diagnostic scanner will be required to activate the pumps.
Which wheels are best for the Octavia A7 with a 1.6 TDI engine?
For 1.6 TDI (105 hp) suitable for wheels of size 288 mm front and 272 mm rear. Optimal options:
- ๐ฅ ATE PowerDisc (article
24.0122-0179.2) - the best price/quality ratio. - ๐ฐ TRW DF4720 - original supplier, but more expensive.
- ๐ก๏ธ Brembo 09.9662.11 - if increased resistance to corrosion is needed.
Avoid uncoated discs - on 1.6 TDI Problems with rust often arise due to low heat load (the discs do not have time to dry out).
