Brake system Ε koda Octavia A7 (2013–2020) requires regular maintenance, and replacing pads is one of the most common procedures. Depending on the driving style and operating conditions, the front pads wear out each time. 30–50 thousand kmAnd the backs are 60–80 thousand km. However, you can not ignore their condition: worn pads not only reduce the effectiveness of braking, but also damage the brake discs, which leads to expensive repairs.

In this article you will find detailed instructions for replacing the pads both-axle Octavia A7including a list of necessary tools, recommendations for the selection of spare parts and Unique nuances for models with ESP and electric parking brake (EPB). We will also analyze the typical mistakes that beginners make, and give tips on extending the service life of the braking system.

When do you need to change brake pads on an Octavia A7?

Manufacturer Ε koda It does not set hard intervals of replacement - it all depends on the intensity of the brakes. But there are obvious signsindicating the need for replacement:

  • πŸ”Š Creaking or whistling when braking - a signal of critical wear of the friction material (often the pads are equipped with metal wear indicators).
  • πŸš— Increased braking distance or "soft" brake pedal - can talk about uneven wear or oil hitting the pads.
  • πŸ”§ Visual wear: friction layer thickness less 3–4 mm (for front pads) or 2–3 mm (for the rear ones).
  • πŸ’‘ Message on the dashboard (for models with wear sensors) - error code 01579 or 01580 in the self-diagnosis system.

On Octavia A7 with electromechanical parking brake (EPB) The rear pads wear out faster due to automatic pull-ups when parking. It is also worth checking the condition of the pads after aggressive driving or operation in mountainous areas - there the load on the brakes increases 2-3 times.

⚠️ Attention! If on the pads or discs appeared deep grooves, cracks or chips - they need to be replaced. immediatelyEven if the friction layer is not yet erased. Such defects lead to uneven braking and vibrations on the steering wheel.
πŸ“Š How often do you check the brake pads on your car?
  • Every 10 thousand km
  • Only when a squeak appears
  • Once a year before maintenance
  • Never checked

Which pads should I choose for the Ε koda Octavia A7?

There are three price categories of pads on the market: budget (from RUB 1,500 per set), middle class (3,000–6,000 rub.) and premium (from 7,000 rub.). For Octavia A7 Critically select the appropriate sleeves brake-disc size (front - 288Γ—25 mm or 312Γ—25 mm for versions with engines 1.8 TSI and 2.0 TSI, rear - 272Γ—12 mm).

For models with ESP system and electronic handbrake (EPB) It is important to choose the pads from integrated wear sensors (If they were previously established) When replacing sensors, it is necessary slip off or purchase new items (articles for the Octavia A7 β€” 1K0 907 625 A).

πŸ’‘

Before purchasing pads, check their compatibility with your modification. Octavia A7 by VIN code. For example, cars with an engine 1.6 TDI (CRTD) have different brake calipers than versions with 2.0 TSI (CZPA).

Tools and materials for replacement

To replace the pads yourself Ε koda Octavia A7 you will need:

  • πŸ”§ Set of sockets and socket wrenches (13 mm, 15 mm, 17 mm for calipers).
  • πŸ”¨ Balloon wrench and a jack (or lift).
  • πŸ› οΈ Brake piston puller (required for rear pads with EPB!).
  • 🧴 Brake fluid DOT 4 (for topping up after replacement).
  • 🧼 Brake cleaner (for example, LIQUI MOLY Bremsen-Reiniger).
  • πŸ”§ Vernier caliper (to measure the thickness of pads and discs).
  • πŸ”Œ Diagnostic scanner (for example, VCDS or OBDeleven) - to reset the service interval after replacement.

For rear pads with electromechanical handbrake Additionally you will need:

  • πŸ”‹ Cordless drill with an adapter for screwing in the piston (or a special tool EPB Service Tool).
  • πŸ“± Laptop with program ODIS or VCDS to put the caliper into service mode.
⚠️ Attention! Do not use WD-40 or other all-purpose lubricants for processing caliper guides - they destroy rubber boots. Use only special high temperature grease (for example, TRW PFG110 or ATE Plastilube).

Step-by-step replacement of front brake pads

Front pads on Octavia A7 It’s easier to replace than the rear ones, since there is no electromechanical handbrake. Follow the algorithm:

  1. Preparation: Stop the engine, engage first gear (or P for automatic transmission) and place chocks under the rear wheels. Loosen the front wheel bolts, then jack up the car and remove the wheel.
  2. Removing the caliper: Unscrew the two bolts securing the caliper to the bracket (usually 15 mm). Carefully hang the caliper on a wire or rope, without disconnecting the brake hose!
  3. Replacing pads: Remove the old pads and clean any dirt from the guide brackets. Install new pads, first applying a thin layer of lubricant to their back side (not to the friction layer!).
  4. Recessing the piston: Using sliding pliers or a special tool, press the caliper piston as far as it will go. Don't twist it - this will damage the boot.
  5. Assembly: Install the caliper in place, tighten the bolts to a torque 30 Nm and put on the wheel. Repeat the procedure for the second wheel.

After replacement press the brake pedal several timesso that the pistons bring the pads close to the discs. Then check the brake fluid level in the reservoir - it may rise when the pistons are retracted.

Check the thickness of the brake discs (minimum 22 mm for the front axle)|

Buy new caliper mounting bolts (recommended to replace)|

Prepare a container for possible drainage of brake fluid|

Check the operation of the caliper guides (there should be no play) -->

What to do if the caliper piston does not retract?

If the piston cannot be pressed in by hand, there may be pressure left in the system. Try unscrewing the brake fluid reservoir cap slightly (without removing it completely). If this does not help, check the caliper for corrosion or damage to the rubber. As a last resort, use a clamp, but be careful not to damage the boot.

Replacing rear brake pads with EPB: nuances and instructions

Rear pads on Octavia A7 with electromechanical parking brake require a special approach. The main difficulty is screwing in the caliper piston, which cannot be done without special tools and diagnostic equipment.

Replacement algorithm:

  1. Activating the service mode: Connect the scanner (VCDS, OBDeleven) and in the menu Block 03 - Brake system select Service mode EPB. This unlocks the piston for screwing.
  2. Removing the caliper: Unscrew the two mounting bolts (usually 15 mm) and remove the caliper by hanging it on a wire. Do not press the brake pedal after removing the caliper!
  3. Screwing in the piston: Use a special tool (such as Hazet 2079-2) or drill adapter. The piston is screwed in clockwise all the way.
  4. Installing new pads: Clean the guides and install the pads, making sure the spring clips snap into place.
  5. Resetting the service mode: Using the scanner, deactivate the EPB service mode and perform parking brake calibration (menu Basic settings β†’ EPB calibration).

If after replacement the indicator on the dashboard lights up EPB, check:

  • πŸ”§ Correct connection of wear sensors (if any).
  • πŸ”„ Correctness of calibration (sometimes it is necessary to repeat the procedure 2-3 times).
  • πŸ“Ά The condition of the wiring to the caliper (often rubs against the wheel).
πŸ’‘

After replacing the rear EPB pads, be sure to check the operation of the parking brake! Start the car, turn on the handbrake and try to drive off in first gear - the car should be held securely.

Common mistakes when replacing pads and how to avoid them

Even experienced car owners sometimes make mistakes that lead to early pad wear or damage to the brake system. Here are the most common:

  • ❌ Ignoring caliper guides: If the guides are not lubricated or cleaned, the caliper will jam, which will lead to uneven pad wear. Lubricate only with special paste!
  • ❌ Incorrect installation of spring clips: On rear pads Octavia A7 fasteners must be installed convex side to the disk. Otherwise the pads will wobble.
  • ❌ Forgetting to reset the service interval: After replacing the pads on models with EPB You need to reset the wear counter through the diagnostic scanner, otherwise an error will appear on the panel.
  • ❌ Reusing old caliper bolts: Caliper mounting bolts - disposable (especially on the front axle). Their tightening torque is 30 Nm, and they may burst when used repeatedly.

Another common problem is "sticking" of pads after replacement. This happens due to:

  • πŸ”§ Incorrect installation of protective plates (they should be clean and smooth).
  • 🧴 Contact of lubricant on the friction layer of the pads or disc.
  • πŸ”© The caliper is skewed when tightening the bolts (tighten them criss-cross).

Running in new pads and maintaining the brake system

After replacing the pads with Ε koda Octavia A7 required running-in - first 200–300 km avoid:

  • 🚦 Sharp braking (especially at high speeds).
  • 🏁 Holding the brake pedal for a long time (for example, on descents).
  • πŸ’¨ Aggressive acceleration followed by braking.

To extend pad life:

  • πŸ”„ Regularly (once every 10 thousand km) clean the calipers and guides from dirt.
  • πŸ’§ Check the brake fluid level and replace it every 2 years (the liquid is hygroscopic and loses its properties).
  • πŸ”₯ Avoid overheating the brakes - after intense braking, let them cool (do not put the car on the handbrake immediately after stopping!).

If you notice that your pads are wearing out unevenly (one side wears out faster), check:

  • πŸ”§ Condition step bearing (wear leads to wheel runout and uneven pad pressure).
  • πŸ“ Geometry brake discs (permissible runout - no more 0.05 mm).
  • πŸ”© Performance brake force regulator (located under the bottom, next to the rear axle).
πŸ’‘

To check the condition of the brake discs without removing the wheel, use endoscope (flexible camera). Pass it through the spokes of the disc and evaluate the thickness and presence of grooves on the brake disc.

FAQ: Frequently asked questions about replacing pads on Octavia A7

❓ Do I need to change brake discs and pads?

Not always. Disks must be replaced if:

  • Their thickness is less than the minimum permissible (22 mm for the front ones, 10 mm for the rear).
  • There are deep grooves on the surface (more 1 mm) or cracks.
  • When braking, vibration is felt in the steering wheel or pedal.

If the discs are normal, it is enough to turn them on a lathe (cost - from 1,500 rubles per axle).

❓ Is it possible to drive if one brake pad squeaks?

Short term - yes, but don't delay replacement. A squeak indicates that the friction material has worn down to metal and the pad is now scratching the disc. If you ignore the problem:

  • The disc will be damaged (replacement or resurfacing will be required).
  • The braking distance will increase.
  • The calipers may jam due to overheating.
❓ How to reset the service interval after replacing the pads?

To reset, use the diagnostic scanner (VCDS, OBDeleven):

  1. Connect to the block 03 β€” Brake system.
  2. Select Adaptation β†’ Channel 01.
  3. Enter value 00000 (for front pads) or 00001 (for the rear ones).
  4. Save the changes and reboot the unit.

For models without a scanner, you can reset the interval through the on-board computer menu: Settings β†’ Service β†’ Reset (if option available).

❓ Why did the brake pedal become soft after replacing the pads?

Probable reasons:

  • πŸ”§ Air entering the system - Brakes need bleeding.
  • πŸ’§ Low brake fluid level (add to the mark MAX).
  • πŸ”© Incorrect caliper installation (check the tightness of the bolts).
  • πŸ”„ Unbroken pads β€” after the first 100 km the pedal should regain its stiffness.

If the problem persists, check master brake cylinder and vacuum booster.

❓ Which pads are better - ceramic or semi-metallic?

The choice depends on your driving style:

Pad type Pros Cons Recommendations
Semi-metallic High heat dissipation, long service life More dusty, noisier, more aggressive towards disks For sporty riding or tough conditions
Ceramic Low dust, quiet, disc-friendly More expensive, perform worse at low temperatures For urban use
Organic Soft, little noise Wear out quickly, not suitable for heavy machines For a relaxed driving style

For Octavia A7 optimal choice - ceramic pads (for example, TRW GDB1546), if you drive mostly around the city, or semi-metallic (Brembo P 24 060) for active driving.
