Original brake discs for ŠKODA Octavia A5: catalog numbers and sizes

On Octavia A5 (2004–2013) brake discs of different sizes were installed depending on the engine and year of manufacture. Original spare parts from ŠKODA/VW are labeled under the brand TRW (conveyor supplier). Below is a table with current catalog numbers and parameters:

Engine model	Front discs (diameter × thickness)	Rear discs (diameter × thickness)	Original number (front/rear)
1.4 TSI (122–160 hp)	288 × 25 mm	256 × 12 mm	1K0 615 301 AB / 1K0 615 601 C
1.6 MPI (102 hp)	256 × 22 mm	232 × 9 mm	1K0 615 301 / 1K0 615 601 A
1.8 TSI (160 hp), 2.0 TSI (200 hp)	312 × 25 mm (ventilated)	256 × 22 mm	1K0 615 301 AD / 1K0 615 601 D
1.9 TDI (105 hp), 2.0 TDI (140 hp)	288 × 25 mm	253 × 12 mm	1K0 615 301 AB / 1K0 615 601 B

⚠️ Attention: On model with RS package (for example, Octavia RS) larger disks with a diameter of 345 mm front. Their catalog numbers are 1K0 615 301 AF (before) and 1K0 615 601 E (back). Check the sizes before purchasing!

Original wheels TRW They are distinguished by high quality cast iron and precise balancing, but their price is often high - from 8,000 to 15,000 rubles per set. An alternative is certified analogues from ATE, Brembo or Bosch, which we will consider next.

Signs of brake disc wear: when is it time to change?

The manufacturer recommends checking the brake discs every 30,000–50,000 km, but the actual service life depends on driving style and the quality of the pads. Here key symptomsindicating the need for replacement:

• 🔧 Vibration on the steering wheel when braking - a sign critical disc deformation (the so-called “beat”). More common on front discs due to high loads.
• 📏 Disc thickness below minimum. For most models Octavia A5 the minimum thickness is indicated on the end of the disc (for example, MIN TH=22 mm). Measured with a caliper.
• 🔥 Deep grooves or cracks on the work surface. It is especially dangerous if they are felt during braking as a “knock” or “grinding”.
• 🚗 Increased braking distance even with new pads. This may indicate overheating of the disks and a change in their structure.

⚠️ Attention: If there are blue spots - this is a consequence of overheating (for example, after a long descent from a mountain with constant braking). Such a disk loses strength and is subject to mandatory replacement, even if the thickness is normal.

You can check the condition of the discs visually through the spokes of the wheel or by removing it. For an accurate diagnosis, use dial indicator (to check runout) and a caliper. Allowable runout - no more 0.05 mm.

Which brake discs to choose for Octavia A5: comparison of brands

The market offers dozens of options - from budget Chinese to premium European ones. We analyzed owner reviews and technical specifications to rank the best brands for Octavia A5:

• 🥇 ATE (Germany) — optimal price/quality ratio. Discs made of high carbon cast iron with corrosion protection. The average price of a set is 6,000–9,000 rubles. Suitable for everyday driving.
• 🥈 Brembo (Italy) - premium segment. Ventilated, perforated wheels for a sporty riding style. Price - from 12,000 rubles. Are different increased heat transfer.
• 🥉 Bosch (Germany) - a reliable budget option. They often come complete with pads. Price - 4,500–7,000 rubles. The downside is that they rust faster.
• 💰 TRW (Original) - the most durable, but also the most expensive. The price of the set is up to 18,000 rubles. Recommended for Octavia RS.
• ⚠️ No-Name (China) - cheap (2,000–4,000 rubles), but often have uneven metal structure, which leads to vibrations.

🔹 Tip: When choosing, pay attention to disk type:

- Solid - cheaper, but dissipate heat worse. Suitable for city driving.

- Ventilated - with internal channels for cooling. Optimal for Octavia with motors 1.8 TSI and 2.0 TDI.

- Perforated/notched - for an aggressive driving style, but the pads wear out faster.

Step-by-step instructions: how to replace brake discs on an Octavia A5 with your own hands

Replacing brake discs with Octavia A5 - a task of medium complexity. If you have tools and an inspection hole (or a jack), it can be completed in 2–3 hours. You will need:

• 🔧 Set of sockets and keys (especially Torx T30 for caliper guides).
• 🔨 Hammer and wooden spacer (for removing stuck disks).
• 🧲 Torque wrench (for tightening bolts to 120 Nm).
• 🧴 Copper grease for caliper guides.
• 🛠️ New brake pads (it is recommended to change them along with the discs).

🔹 Procedure:

1. Preparation: Stop the engine, engage first gear (or P on automatic transmission) and place chocks under the rear wheels. Loosen the wheel bolts, then jack up the car and remove the wheel.
2. Removing the caliper: Unscrew the two caliper mounting bolts (usually Torx T30), then carefully hang the caliper on a wire to the spring - Do not let it hang on the brake hose!
3. Removing the disk: Remove the retaining screw (if present) and try to pull the disk off. If it sticks, gently tap it with a hammer through the wooden spacer along the rim.
4. Installing a new disk: Clean the hub from rust, install a new disc and tighten the guide screw (torque 8 Nm).
5. Assembly: Install new pads, lubricate the caliper guides and reassemble everything in reverse order. Tightening the caliper bolts - 30 Nm, wheel bolts - 120 Nm.

⚠️ Attention: After replacing disks first 200 km Avoid sudden braking - the pads need to get used to it. Also check the brake fluid level, as new pads may push the caliper pistons out more.

What to do if the disk cannot be removed?

If the disc is stuck to the hub, use a penetrating lubricant (for example, WD-40) and let it run for 10–15 minutes. Then gently tap the disc with a hammer through a wooden block in a circle. As a last resort, you can use a puller, but do not use excessive force - you risk damaging the hub.

Perforated vs. smooth wheels: which is better for the Octavia A5?

One of the most common questions among owners Octavia A5 — which disks are more efficient: perforated (with holes) or smooth? Let's look at the pros and cons of each type:

Disk type	Benefits	Disadvantages	Recommendations
Smooth	✅ Last longer ✅ Cheaper ✅ Less wear on pads	❌ Worse heat dissipation ❌ Risk of deformation due to overheating	For city driving and engines up to 1.6 MPI
Perforated	✅ Cool better ✅ Resistant to overheating ✅ More effective in wet weather	❌ Wear out faster ❌ 30–50% more expensive ❌ A squeak may appear	For 1.8 TSI/2.0 TDI and active driving style
Slotted	✅ Optimal gas removal ✅ Less vibration ✅ Remains effective longer	❌ Pads wear out more ❌ Can accumulate dirt	For sports versions (Octavia RS)

🔹 Conclusion: For most owners Octavia A5 with motors 1.4–1.6 optimal smooth ventilated discs (for example, ATE). If you have 2.0 TSI or you like dynamic driving, it's worth considering perforated (for example, Brembo).

⚠️ Attention: Perforated discs require special pads with a soft composition (for example, Ferodo Premier), otherwise they will wear out quickly.

Common mistakes when replacing brake discs and how to avoid them

Even experienced car owners sometimes make mistakes that lead to vibrations, squeaks or premature wear. Here top 5 misses and how to prevent them:

• 🔧 Incorrect bolt tightening. Use a torque wrench! Overtightened caliper bolts can deform the disc, while undertightened caliper bolts can lead to play.
• 🧴 Lack of lubrication on the guides. Always apply copper grease on the caliper guides, but avoid getting it on the pads or disc!
• 🔨 Using old pads. New discs require new pads - otherwise uneven wear is guaranteed.
• 🚗 Ignoring hub runout. Before installing the disc, check the hub for runout (tolerance - 0.03 mm). If necessary, sharpen or replace it.
• 🔥 Heavy braking after replacement. The first 200 km, the pads grind into the disc. Aggressive braking during this period leads to uneven wear.

🔹 Useful lifehack: After replacing disks drive 50–100 km in gentle mode, then do several smooth braking from speed 80–60 km/hso that the pads rub in evenly.

FAQ: answers to frequently asked questions about Octavia A5 brake discs

Is it possible to sharpen brake discs instead of replacing them?

Grooving is possible if the thickness of the disc exceeds the minimum allowable (indicated on the end of the disk). However, this is a temporary solution: a machined disc overheats faster and becomes deformed. For Octavia A5 the groove is justified only when slight runout (up to 0.05 mm).

Which discs are better - original or analog?

Original wheels TRW guarantee 100% compatibility and long service life, but their price is too high. High-quality analogues (ATE, Brembo) are often not inferior in characteristics, but cost 30–40% less. The main thing is to avoid no-name brands with a dubious reputation.

Do I need to replace brake discs in pairs?

Yes, necessarily! Replacing only one disc (for example, the right front) will lead to uneven braking and pull the car to the side. An exception is if the disk is mechanically damaged (for example, after an accident), and the second one is in perfect condition.

How often should brake discs be checked?

Recommended interval - every 30,000 km or every time you replace the pads. Also check the disks after severe overheating (for example, after a long descent from a mountain) or if you notice vibrations on the steering wheel.

Is it possible to install perforated wheels on a standard Octavia A5?

Yes, but keep in mind that they pads wear out faster and require more frequent replacement. For motors 1.4–1.6 this is not always justified, but for 1.8 TSI/2.0 TDI Drilled discs can improve braking performance.
