Replacing brake pads with Ε KODA Octavia A5 (body 1Z3, 2004–2013) is a procedure that many car owners prefer to do on their own. And for good reason: with the right approach, the work will take 1–2 hours, save 3–5 thousand rubles on service stations and guarantee the quality of the installation. However, there are nuances that distinguish front replacement from rear, as well as features for versions with ESP and without her.

In this article you will find step-by-step instructions with photos, detailed videos, pad and disc compatibility tables, as well as answers to frequently asked questions. We will look at what tools you will need, how to avoid mistakes when working with calipers, and why, after replacement, it may squeaking or rattling brake mechanism - and what to do about it. If you have never worked on the brake system, start with theory: this will protect you from typical problems, e.g. jammed caliper piston or uneven wear of new pads.

When to change brake pads on Octavia A5

The manufacturer recommends checking the thickness of the pads every 15–20 thousand km, but the actual service life depends on driving style, quality of spare parts and operating conditions. Here are the key signs that it's time to act:

  • πŸ”Š Creaking or whistling when braking - often signals critical wear of the linings (≀ 2 mm remaining). On Octavia A5 they usually creak front pads, since they take on up to 70% of the load.
  • πŸš— Increased braking distance or a "soft" pedal - may indicate uneven wear or oil on the working surface.
  • πŸ”§ Visual wear: Cracks, chips or metal shavings on the pads. You can check through the spokes of the wheel or by removing it.
  • πŸ“ Friction layer thickness ≀ 3 mm (for anterior) or ≀ 2 mm (for rear). Measured with a caliper.

On Octavia A5 with motors 1.6 MPI, 1.8 TSI or 2.0 TDI front pads run on average 30–50 thousand km, rear - 80–100 thousand km. But if you often drive along mountain serpentines or tow a trailer, the resource is reduced by 30–40%. Please note: on versions with ESP (electronic stabilization system), the rear pads may wear out faster due to active wheel braking.

⚠️ Attention: If deep grooves appear on the pads or they are β€œpolished” to a shine, this is a sign of a faulty caliper (jammed piston) or deformation of the brake disc. In this case Replacing the pads is not enough β€” diagnostics of the entire system is required.

Which pads to choose for Octavia A5: original vs analogues

Original pads from Ε KODA/VW have articles:

  • πŸ”Ή Front: 1K0 698 151 (without wear indicator) or 1K0 698 151 A (with sensor).
  • πŸ”Ή Rear: 1K0 698 451 (disc brakes) or 1K0 698 451 A (with sensor).

They cost from 3,500 to 5,000 rubles per set per axle. However, many owners choose analogues from trusted brands that are not inferior in quality, but are 30–50% cheaper. Here are the best options:

Brand Article (front) Article (rear) Price per axle, rubles Features
TRW GDB1446 GDB1450 2 200–2 800 Soft, low dust, suitable for aggressive driving
ATE 13.0460-2864.2 13.0460-3072.2 2 500–3 200 Rigid, long life, but can creak for the first 200 km
Brembo P 24 020 P 24 023 3 000–3 800 Sports series, high friction coefficient
Bosch 0 986 494 219 0 986 494 220 2 000–2 500 Budget option, average resource

When choosing, pay attention to friction material composition:

  • πŸ”₯ Semi-metallic (up to 65% metal) - durable, but noisy and aggressive to disks.
  • 🌿 Organic (resin-based) - quiet, but wear out faster.
  • πŸ’Ž Ceramic - the most expensive, minimal dust, but require warming up.
⚠️ Attention: On Octavia A5 with rear drum brakes (rare, but found on basic versions) the pads have an article number 1K0 698 651. Replacing them is more difficult - it requires removing the drum and adjusting the handbrake sprocket.
πŸ“Š What pads do you prefer to install?
  • Original Ε KODA/VW
  • TRW
  • ATE
  • Brembo
  • Bosch
  • Others

Tools and materials for replacement

To change the pads yourself, prepare:

Wheelbrace (17 or 19)

Sockets (13, 15, 17 mm)

Ratchet handle or crank

Hammer and wooden block

Brake piston puller (or clamp)

WD-40 or similar penetrating lubricant

Copper grease for caliper guides

Brake fluid DOT 4 (to be topped up)

Gloves and glasses-->

Additionally you may need:

  • πŸ”§ Metal brush - to clean the caliper from rust.
  • πŸ“ Vernier caliper - to measure the remaining thickness of pads and discs.
  • πŸ”¨ Vise β€” if you need to press in the rear caliper piston (on models with ESP).

Before starting work necessarily:

  1. Park the car on a level surface, turn on 1st gear (or P on automatic transmission) and place chocks under the rear wheels.
  2. Loosen the wheel bolts before lifting on the jack.
  3. Remove the brake fluid reservoir cap - this will make it easier to recess the piston calipers
πŸ’‘

If you are changing the pads for the first time, take photographs of the location of all parts before disassembling. This will help avoid assembly errors, especially with the springs and brackets on the rear calipers.

Step-by-step replacement of front brake pads

Front pads on Octavia A5 It's easier to change the rear ones, since the caliper is here floating (with one guide). Follow the instructions:

  1. Remove the wheel and clean the caliper from dirt with a brush. Please note wear indicator (if there is one) - it cannot be damaged.
  2. Unscrew the lower caliper bolt (13 or 15 mm head). There is no need to touch the top bolt - the caliper will hang on it.
  3. Lift the caliper up and secure it with wire or rope so that it does not hang on the brake hose.
  4. Remove old pads. If they are stuck, carefully pry them off with a screwdriver.
  5. Sink the caliper piston. To do this, use a puller or clamp. Do not press the piston with a hammer - this will damage the boot!
  6. Install new pads, having previously applied copper grease on their back side (not on the friction layer!).
  7. Reassemble everything in reverse order. After installation, press the brake pedal 3-4 times until the piston is in working position.

Important nuance: on Octavia A5 with motors 1.8 TSI and 2.0 TSI calipers may have additional pad clamps (metal brackets). They must be carefully removed and reinstalled, otherwise the pads will hang loose.

What to do if the piston does not recess?

If the caliper piston does not return to its original position, the reasons may be the following:

1. Stuck due to corrosion - Apply WD-40 and gently tap with a hammer through a wooden block.

2. The boot is damaged - The caliper will need to be replaced or its repair kit will be required.

3. There is pressure left in the system β€” open the brake fluid reservoir cap and try again.

Replacing rear brake pads: features and difficulties

Rear pads on Octavia A5 change is more difficult due to two key factors:

  1. Caliper with fixed bracket β€” there are two mounting bolts, and to access the inner pad you need to remove the entire caliper.
  2. Handbrake mechanism β€” on the rear pads there is a handbrake drive lever that needs to be installed correctly.

Step by step instructions:

  1. Take off the wheel and unscrew. both caliper bolts (15 mm head).
  2. Remove the caliper and hang it on a wire. Do not disconnect the brake hose!
  3. Remove the old pads. Please note spring clips - they are easy to lose.
  4. Press down the caliper piston. On the rear calipers Octavia A5 need a piston rotate clockwise (use a special puller or pliers).
  5. Install new pads, after first moving the handbrake lever from the old ones to the new ones.
  6. Assemble the caliper. After installation adjust the handbrake (3-4 clicks on the lever).

On models with ESP after replacing the rear pads it may ABS light is on. This is normal - the error will clear after 2-3 braking or using a scanner (for example, VCDS).

πŸ’‘

On the rear pads Octavia A5 often wears out guide spring (article 1K0 615 123). If it is stretched or broken, the pads will wobble and fit unevenly to the disc.

Common mistakes and how to avoid them

Even experienced car owners sometimes make mistakes when replacing pads. Here are the most common:

  • πŸ”§ Incorrect installation of wear sensor β€” if it is swapped (left/right), it will trigger falsely.
  • πŸ›‘ Forgot to recess the caliper piston β€” the new pads will not fit into place, and the brake fluid will overflow through the reservoir.
  • 🧴 Used the wrong lubricant β€” graphite or lithol are not suitable! Only copper paste or special grease for calipers (for example, ATE Plastilube).
  • πŸ”© Caliper bolts not tightened enough - this leads to misalignment of the pads and uneven wear.

Another typical problem is squeak after replacement. Causes and solutions:

Reason for the squeak How to fix
New pads didn't get used Drive 200–300 km with moderate braking
Metal parts rub against the disc Check the installation of anti-squeak plates
Dirt got between the pad and caliper Remove the pads, clean the seats
Cheap pads with a hard friction layer Replace with ceramic or original ones
πŸ’‘

If the brake pedal becomes soft after replacement, bleed the brake system. On Octavia A5 You can do this yourself using a syringe and tube, but it is better to use a vacuum pump.

When to change brake discs and how much does it cost?

Brake discs on Octavia A5 serve on average 80–120 thousand km, but their condition must be checked every time the pads are replaced. Critical parameters:

  • πŸ“ Disc thickness less than the minimum (indicated on the disc itself, usually 18–20 mm for the front and 8–10 mm for the rear).
  • πŸŒ€ Disc runout more than 0.1 mm (checked with an indicator or visually when braking - there will be vibration on the steering wheel).
  • πŸ” Deep grooves or cracks (more than 0.5 mm).

Original wheels for Octavia A5:

  • πŸ”Ή Front: 1K0 615 301 (ventilated, diameter 288 mm).
  • πŸ”Ή Rear: 1K0 615 601 (solid, diameter 255 mm).

Analogues from ATE, Brembo or TRW will cost 2,500–4,000 rubles per disc. Replacing disks with your own hands takes 3-4 hours (with breaks for cooling - disks cannot be placed hot!).

⚠️ Attention: On Octavia A5 with motor 2.0 TDI (140 hp) front discs are thicker - 312 mm (1K0 615 301 J). Installing "non-original" discs will lead to a decrease in braking efficiency!

FAQ: Frequently asked questions about replacing pads on Octavia A5

Is it possible to change the pads on only one axle (for example, only the front ones)?

No! Pads are always changed in pairs on the same axis (both front or both rear). If you replace only one pad, the braking force will be distributed unevenly, which will lead to the car pulling to the side when braking.

Do I need to bleed the brakes after replacing the pads?

As a rule, no. Bleeding is required only if you have disconnected the brake hoses or air has appeared in the system (for example, due to a critically low fluid level). However, after replacing the rear pads on models with ESP may be required adaptation of brake mechanisms through a diagnostic scanner.

How long does it take to replace pads on an Octavia A5?

For the first time? Schedule 2–3 hours to the front pads and 3–4 hours to the rear (due to difficulties with the caliper and handbrake). Experienced craftsmen can do it in 1–1.5 hours per axle.

Is it possible to drive if the new pads squeak?

Yes, but only if the creaking appeared immediately after replacement and is not accompanied by vibration or deterioration in braking. This is a normal running-in process (up to 300 km). If the creaking does not go away, check:

  • Correct installation anti-squeak plates.
  • Absence gaps between the pad and the caliper.
  • The quality of the pads (cheap ones often squeak due to the hard material).
What brake fluid should I fill in the Octavia A5?

Manufacturer recommends DOT 4 (article G 005 000 M2). The volume of the system is about 1 liter. The liquid is hygroscopic, so it needs to be changed every 2 years, even if the mileage is small.
