Rear brake discs of the Škoda Octavia A7: how to choose and replace correctly

Škoda Octavia A7 - a car that is valued for its reliability and practicality, but even its brake system requires regular attention. Rear brake discs, unlike the front ones, are often left without proper control until they begin to “bring surprises”: vibrations during braking, squeaks or increased braking distance. In this article we will look at everything the owner needs to know. Octavia A7 (including restyled versions 2017–2023): from the choice of disks to the nuances of replacing them.

Features of the rear brakes Octavia A7 - their load is lower compared to the front ones, but this does not mean that they last forever. Average resource of original disks - 80–120 thousand km, but an aggressive driving style, frequent overheating or corrosion can reduce this period by half. In addition, on Octavia A7 with engines 1.4 TSI, 1.8 TSI and 2.0 TDI rear discs are often thinner than the front ones (22–25 mm vs. 28–30 mm), making them more vulnerable to deformation.

If you notice that the brake pedal has become “soft”, and when braking sharply you feel a beating in the steering wheel, these are direct signs of problems with the discs. But don’t rush to change them: sometimes re-grooving or replacing the pads is enough. Next, we will look at how to diagnose a malfunction, select high-quality spare parts and avoid common mistakes when replacing.

Original rear brake discs: part numbers and features

Factory wheels for Škoda Octavia A7 supplies TRW (part of the concern ZF), but the assembly line also uses parts from ATE and Brembo. Original part numbers depend on the year of manufacture and engine type. Below is a table with current numbers for the most common modifications:

Model and engine	Years of manufacture	Original article	Size (diameter × thickness)
Octavia A7 1.4 TSI (140 hp)	2013–2016	5Q0 615 601 A	272 × 22 mm
Octavia A7 1.8 TSI / 2.0 TSI (180–220 hp)	2013–2020	5Q0 615 601 D	288 × 25 mm
Octavia A7 1.6 TDI / 2.0 TDI (105–184 hp)	2013–2023	5Q0 615 601 C	272 × 22 mm (for 1.6) / 288 × 25 mm (for 2.0)
Octavia A7 FL (facelift) all engines	2017–2023	5Q0 615 601 J (for 288 mm) 5Q0 615 601 H (for 272 mm)	272/288 × 22/25 mm

Important: disks for Octavia A7 with electromechanical parking brake (EPB) have special grooves for sensors. If you install a “bare” disc without slots, the EPB system will generate an error P1750 (parking brake drive malfunction). Also note ventilated vs. unventilated disks: on most versions Octavia A7 rear discs are unventilated, except for sports modifications (for example, RS).

The cost of original discs is from Škoda — 8 000–12 000 ₽ per piece, but they can be replaced with high-quality analogues from ATE, Brembo or Textar, which will cost 2–3 times less without loss of reliability.

Signs of wear on rear brake discs

Rear discs on Octavia A7 wear out slower than the front ones, but their condition is critical for safety. Here are the key symptoms that indicate the need for replacement or repair:

• 🔍 Visual defects: Deep grooves, cracks or “waves” on the surface of the disc. The normal thickness of a new disc is 22–25 mm, the minimum permissible (taking into account wear) is 19–20 mm.
• 🚗 Vibrations when braking: if the steering wheel or brake pedal “beats” at speeds above 60 km/h, the disc is most likely warped from overheating.
• 🔊 Creaks and noises: A metallic grinding noise when braking may indicate the pads have worn down to metal, damaging the disc.
• 🛑 Increased braking distance: If the rear brakes “do not hold” and the pads are normal, the problem may be deformation or excessive wear of the discs.
• 💡 EPB lamp on the dash: If the parking brake icon lights up and the lever is lowered, check the sensors on the discs (relevant for versions with EPB).

The critical thickness of the rear discs for the Octavia A7 is 18 mm. If the disk has worn down to this value, it must be replaced, since further use will lead to cracks and the risk of rupture when heated.

To check the thickness of the rim without removing the wheel, use a caliper or special wear indicator (sold in auto stores). Measure the thickness at 3-4 points around the circumference - a difference of more than 0.05 mm indicates uneven wear.

Choosing analogues: which brands are reliable?

Original wheels from Škoda - not always the best choice: their price is too high, and their quality is often inferior to their premium counterparts. Below is a rating of brands recommended by service station technicians and owners Octavia A7:

• 🥇 ATE (Germany) - the optimal combination of price and quality. The discs are made of high-carbon cast iron with corrosion protection. Articles: 24.0120-0176.2 (272 mm), 24.0120-0206.2 (288 mm).
• 🥈 Brembo (Italy) - premium segment, suitable for aggressive driving. They are distinguished by an increased resource (up to 150 thousand km) and improved heat dissipation. Articles: 09.9708.11, 09.9709.11.
• 🥉 Textar (Germany) - a budget option with good wear resistance. Suitable for a relaxed driving style. Articles: 92250100, 92250200.
• ⚠️ TRW (Spain) - original supplier for VW Group, but the quality varies depending on the batch. Articles: DF4836, DF4837.
• 💰 Bosch (Germany) - a universal choice for urban use. Articles: 0 986 479 720, 0 986 479 721.

When choosing analogues, pay attention to:

1. Certification: disks must comply with the standard ECE R90 (European safety certificate).
2. Material: optimal - gray cast iron with alloying additives (for example, molybdenum to increase strength).
3. Coverage: zinc or aluminum coated wheels resist corrosion longer.
4. Complete set: the kit should contain mounting bolts (if they are not reusable).

Avoid cheap discs without a brand or with inscriptions like “Made in China” without certificates. Such details often have uneven metal structure, which leads to cracks when heated. For example, disks from Febi or Mapco may cost less, but their service life rarely exceeds 40–50 thousand km.

What is perforation and groove of discs?

Perforated discs (with holes) dissipate heat better, but wear out faster and are prone to cracks. Grooving (cutting grooves) improves adhesion to the pads, but reduces the life of the disc by 10–15%. On the Octavia A7, such discs are installed only on sports versions (for example, Octavia RS).

Step-by-step replacement of rear brake discs on Octavia A7

Replacing rear discs with Octavia A7 more difficult than on the front ones, due to the parking brake (especially if it is electromechanical - EPB). Below are detailed instructions taking into account the nuances for different versions.

Required tools:

• 🔧 17 mm socket wrench (for hub bolts).
• 🔧 Head E14 (for disk mounting bolts).
• 🔧 Jack and supports (or lift).
• 🔧 Brake pad puller (if EPB).
• 🔧 Torque wrench (tightening torque: 120 Nm).
• 🔧 WD-40 or similar lubricant.

Work order:

1. Preparation: Place the car on a level surface, engage first gear (or P for automatic transmission) and loosen the wheel bolts. Raise the rear end on a jack and remove the wheel.
2. Removing the caliper: Unscrew the two caliper mounting bolts (usually 13 or 15 mm), then carefully hang the caliper on a wire without disconnecting the brake hose.
3. Removing the disk:
   • For versions without EPB: Unscrew the screw securing the disc to the hub (head E14) and remove the disc.
   • For versions with EPB: first disconnect the battery, then through a diagnostic scanner (for example, VCDS) put the brake mechanism into maintenance mode. Only after this can you remove the disc.

Cleaning and Installation: Remove rust from the hub with a wire brush, apply a thin layer of copper grease to the adjacent surface. Install the new disc and tighten the bolts crosswise.

Reassembly: Install the caliper, pads (if new) and wheel. Tighten the hub bolts to torque 120 Nm.

Bleeding the brakes: After replacing the discs, be sure to bleed the brake system to remove air.

⚠️ Attention: On Octavia A7 with EPB You can’t just unscrew the disk - you first need to enter the system into service mode through diagnostics. Otherwise, the parking brake drive will be blocked and will have to be reset manually, which may damage the mechanism.

If you do not have access to diagnostic equipment (for example, VCDS or OBDeleven), contact the service station. Independently “resetting” the EPB without a scanner is fraught with errors in the control unit.

Typical replacement mistakes and how to avoid them

Even experienced car owners make mistakes when working with rear brakes Octavia A7. Here are the most common ones and how to prevent them:

• 🔧 Incorrect tightening torque: If you overtighten the hub bolts (more than 120 Nm), the disc may become deformed. Use a torque wrench!
• 🔥 Ignoring hub corrosion: Rust between the hub and disc causes runout. Always clean the surface before installation.
• 🚫 Reusing Old Bolts: on Octavia A7 disc mounting bolts are often disposable (with thread lock). Their repeated use risks loosening the fastening.
• 🔄 Failure to follow the tightening order: Hub bolts need to be tightened criss-cross, and not in a circle, to avoid distortion of the disk.
• 💻 Failure to reset EPB before removing drive: This is the most common mistake leading to blocking of the brake mechanism. Always use a scanner!

⚠️ Attention: If the brake pedal becomes soft after replacing the discs, this is a sign of air getting into the system. It is urgent to bleed the brakes, otherwise braking efficiency will drop by 30–50%.

Another typical problem is new discs squeak in the first 200–300 km. This is normal: the pads are grinding in. But if the squeak does not go away longer, check:

• The quality of the pads (they must be from the same brand as the discs).
• Availability of lubricant on the caliper guides.
• No burrs on the working surface of the disc.

Cost of work and spare parts: where is it cheaper?

Cost of replacing rear brake discs Octavia A7 depends on the type of parking brake actuator and region. Below are the average prices in Russia for 2026:

Service/Spare part	Cost (rubles)	Notes
Original disk (1 pc.)	8 000–12 000	Price for disks 5Q0 615 601 (272/288 mm).
Premium analogue (ATE/Brembo)	3 500–6 000	Recommended choice for most owners.
Replacing drives (without EPB)	1 500–2 500	Cost per axle (2 discs).
Replacing drives (with EPB)	3 000–5 000	More expensive due to the need for diagnostics.
Bleeding the brakes	1 000–1 500	Mandatory after replacing disks.

You can save money if:

• 🛒 Buy discs and pads as a set (they often give a discount of up to 10%).
• 🔧 Changing disks yourself (but only if there is no EPB!).
• 📲 Look for promotions on EPB diagnostics (some service stations offer a free reset when purchasing spare parts from them).

Don't skimp on brake pads: cheap friction materials quickly wear out new discs. Optimal pairs:

• Discs ATE + pads ATE Ceramic.
• Discs Brembo + pads Brembo P85064.
• Discs Textar + pads Textar 2462501.

Brake system maintenance: how to extend the life of discs

Rear brake disc service life Octavia A7 can be increased by 1.5–2 times if you follow simple rules:

• 🚘 Avoid hard braking at high speed - this overheats the disks and leads to deformation.
• 💦 Wash your wheels in winter: Salt and reagents accelerate corrosion. Use special cleaners (for example, Liqui Moly Bremsen-Reiniger).
• 🔄 Change your pads on time: pads worn down to metal scratch the disc, reducing its life.
• 🛠️ Check the calipers: soured guides or caliper pistons lead to uneven disc wear.
• 🌡️ Let the disks cool down after intensive braking (for example, after descending from a mountain). Do not put the car on the handbrake immediately after stopping - this will deform the disk.

⚠️ Attention: If on Octavia A7 With EPB, do not use the parking brake for a long time (for example, in winter), the drive may sour. Tighten and release the handbrake once a month to keep the mechanism moving.

It is also useful to check every 10–15 thousand km:

• The thickness of the discs (with calipers).
• Condition of the brake hoses (cracks or leaks).
• Brake fluid level (should be between MIN and MAX).

If you frequently drive off-road or in high humidity conditions, treat your rims anti-corrosion composition (for example, CRC Brake Parts Cleaner). This will prevent rust from forming on non-working surfaces.

Frequently asked questions about Octavia A7 rear brake discs

Is it possible to sharpen the rear discs instead of replacing them?

Yes, but only if their thickness is not less 20 mm (for 22mm discs) or 23 mm (for 25 mm). Grooving costs 1,000–1,500 rubles per disc, but this is a temporary solution - the service life after grooving is reduced by 30–40%. On Octavia A7 with EPB, a groove can disrupt the operation of the sensors, so it is better to replace the disc.

Why do brakes squeak after replacing discs?

Creaking in the first 200–300 km is normal (the pads are rubbing in). If the squeak does not go away:

• Check the compatibility of the pads and discs (they must be from the same brand or a recommended pair).
• Apply anti-squeak paste on the back side of the pads (for example, ATE Plastilube).
• Make sure the caliper is not warped and the guides are lubricated.

What is the service life of the rear brake discs on the Octavia A7?

Average resource:

• Original wheels: 80–120 thousand km.
• Premium analogs (ATE, Brembo): 100–150 thousand km.
• Budget analogues: 50–80 thousand km.

Wear is influenced by: driving style, pad quality, operating conditions (city/highway) and climate (humidity accelerates corrosion).

Do I need to change the pads along with the discs?

Not required, but recommended. New discs + old pads take longer to break in and may squeak. If the pads are worn less than 50%, they can be left, but:

• Check the remaining thickness (minimum 3–4 mm).
• Make sure the friction material is not peeling off.
• Clean the pads from dirt and oil.

What should I do if the EPB light comes on after replacing the drives?

This means that the parking brake system has not been reset to service mode. Solution:

1. Connect the diagnostic scanner (VCDS, OBDeleven).
2. Go to block 53 — Parking Brake.
3. Select Service Mode → ON.
4. After replacing the disks, return to the menu and turn off the service mode.

If there is no scanner, contact a service station - an independent reset without equipment can damage the EPB drive.
