When and why you need to change the rear pads on an Octavia

Rear brake pads on Ε KODA Octavia (regardless of generation - A5, A7 or restyled FL) wear out more slowly than the front ones, but their condition is critical for safety. Unlike the front discs, the rear ones are often equipped drum mechanisms (on basic configurations) or disc with hand brake (on versions with ESC and ASR). Ignoring wear risks not only worsening braking, but also damage to the brake discs or drums, which will cost many times more.

The main signs that the pads require replacement:

  • πŸ”Š Creaking or whistling when braking (especially at low speeds). On an Octavia with rear discs, this is often a signal about critical wear of the friction layer up to 2–3 mm.
  • πŸš— Car withdrawal to the side when pressing the brake pedal - may indicate uneven pad wear or a stuck caliper.
  • πŸ›‘ Increased pedal travel or its vibration. On models with ESP this sometimes results in an error 01314 β€” Brake Pressure Sensor.
  • πŸ”§ The handbrake doesn't hold even on the third click - a typical problem for rear drum pads Octavia A5.

Rear pad life varies from 40 to 80 thousand km, but depends on driving style, quality of spare parts and operating conditions. For example, on Octavias with DSG and frequent engine braking, the pads wear out faster. You can check their condition visually through the inspection window on the drum or by removing the wheel (for disc brakes).

Which pads to choose: original vs analogues

Original rear pads for Ε KODA Octavia supplies TRW (catalog number depends on the type of brake system). For example, for Octavia A7 with rear discs this is the article number 1K0 698 451 J, and for drum mechanisms - 6Q0 698 651. The cost of the original starts from 3,500 rubles per set, but many owners choose analogues that are 30–50% cheaper.

Proven analogues for different generations of Octavia:

Brake type Manufacturer Article Approximate price, rubles Features
Disc (A7/FL) ATE 13.0460-7107.2 2 800 Soft clutch, little dust
Disc (A5) Brembo P 58 040 3 200 High temperature resistance, suitable for aggressive riding
Drum (A5) Ferodo FSB651 2 100 Long service life, but may squeak for the first 200 km
Disk (RS) Textar 2465501 3 500 Optimized for sports versions

When choosing analogues, pay attention to:

  • πŸ” ECE R90 certification β€” guarantee of compliance with European safety standards.
  • πŸ“¦ Completeness: The box should contain pads, guide plates and caliper lube (if applicable).
  • πŸ”§ System compatibility ESP β€” on Octavias with electronic handbrake (EPB) you need pads with a wear sensor.
⚠️ Attention: On Octavia A7 with EPB (electronic handbrake) after replacing the pads is required caliper adaptation via diagnostic scanner (VCDS, ODIS). Without this, the brakes may not work correctly, and the handbrake will not lock.

Tools and preparation for replacement

To replace the rear pads with Ε KODA Octavia you will need:

  • πŸ”§ Set of sockets and keys: end on 13, 15, 17 mm, hexagon 7 mm (for some models).
  • πŸ”¨ Balloon wrench and a jack (or lift).
  • 🧲 Magnetic holder - so as not to lose the guide pins during disassembly.
  • 🧴 Caliper Lubricant (for example, TRW PFG110 or Slipkote 220-R DBC).
  • πŸ”‹ EPB Reset Scanner (if the car has an electronic handbrake).

Before starting work:

Cool the brake discs (do not work immediately after the trip)|Disconnect the negative terminal of the battery (for models with EPB)|Raise the rear of the car and secure it on supports|Remove the wheel and clean the caliper/drum from dirt|Prepare new pads and tools-->

On Octavia A5 with drum brakes you will additionally need:

  • πŸ”§ Puller for tension springs (or needle nose pliers).
  • πŸ”¨ Hammer and wooden spacer for careful removal of the drum.
⚠️ Attention: On models with ESP and ASR after replacing the pads the error may come on 01314 (brake pressure sensor). This is due to the automatic air intake when the caliper is disconnected. The solution is to bleed the brakes or reset the adaptations via a scanner.

Step-by-step replacement of rear pads on an Octavia with disc brakes

The instructions are relevant for Octavia A7/FL and versions A5 with rear discs (eg 1.8 TSI or 2.0 TDI). On vehicles with EPB before starting work necessarily put the handbrake into service mode through the scanner or the on-board computer menu (Settings β†’ Service β†’ Electronic handbrake).

Step 1: Removing the caliper

Unscrew the two caliper mounting bolts (usually 13 mm or 15 mm). Carefully hang the caliper on a wire or special hook, without disconnecting the brake hose. If the caliper is stuck, use penetrating lubricant (WD-40 or Liqui Moly MoS2).

Step 2: Replacing the pads

Remove the old pads and guide plates. Clean the seats from rust and dirt. Install new pads, first applying a thin layer copper grease on the contact surfaces (but not on the friction layer!).

Step 3. Recessing the caliper piston

On Octavias with EPB The caliper piston is screwed in clockwise (use a tool to press in the piston with grooves). On models without EPB the piston is simply recessed using sliding pliers. Do not use a screwdriver - this will damage the boot!

Step 4. Assembly and adaptation

Install the caliper in place, tighten the bolts to a torque 30 Nm. For vehicles with EPB:

  1. Connect the scanner and run the command Caliper adaptation.
  2. Activate the handbrake in the on-board computer menu.
  3. Bleed the brakes (press the pedal 5-7 times until resistance appears).
πŸ’‘

If after replacing the pads the brake pedal becomes β€œsoft,” bleed the system diagonally: right rear β†’ left front β†’ left rear β†’ right front.

Features of replacement for Octavia with drum brakes

Drum brakes are found on Octavia A5 in basic configurations (for example, with engines 1.4 MPI or 1.6 FSI). Replacing them is more difficult due to the springs and the handbrake mechanism, but if you have the tools you can do it in 1–1.5 hours.

Step 1. Removal of the drum

Unscrew the guide pins (if any) and remove the drum. If it gets stuck, gently tap the edge with a wooden mallet. Do not hit the center - this will deform the hub!

Step 2. Disassembling the mechanism

Remove the tension springs (use a puller or pliers), then remove the pads and spacer bar. Please note handbrake cable β€” it needs to be disconnected from the block lever.

Step 3. Installing new pads

Before assembly, clean all parts from dirt and apply heat-resistant lubricant to friction points (for example, Molykote G-Rapid Plus). Install the new pads, starting with the lower spring, then connect them with a spacer.

Step 4: Adjusting the handbrake

After installing the drum, adjust the tension of the handbrake cable. On Octavia A5 this is done with a nut under the rear axle protection (you need a wrench for 10 mm). A correctly adjusted handbrake should lock onto 3–4 clicks.

What to do if the drum cannot be removed?

If the drum is stuck to the hub, try:

1. Apply penetrating lubricant to the edge and wait 10–15 minutes.

2. Gently tap in a circle through a wooden spacer.

3. Use a puller with claws (for example, KUKKO 21-1).

4. As a last resort, drill holes in the drum and screw in bolts to β€œpull” it from the hub.

Common mistakes and how to avoid them

Even experienced car owners make mistakes when replacing rear pads with Ε KODA Octavia. Here are the most common:

  • πŸ”§ Incorrect tightening torque caliper bolts. On Octavia it is 30 Nm for aluminum calipers and 45 Nm for cast iron.
  • 🧴 Using the wrong lubricant. For example, Litol or Solid oil are destroyed at high temperatures. Use only specialized compounds.
  • πŸ”‹ Forget to adapt EPB. Without this procedure, the handbrake will not work, and an error will appear on the dashboard 01314.
  • πŸš— Incorrect spring installation on drum brakes. This leads to uneven wear of the pads and the car pulling away when braking.

Another typical problem is new pads squeak. On Octavias this is often associated with:

  • πŸ”Š No anti-squeak plates (they need to be moved from the old pads or bought new ones).
  • 🧼 Contaminated brake disc. Before installing the pads, clean the disc with alcohol or a special cleaner (Brembo Cleaner).
πŸ’‘

After replacing the pads, avoid sharp braking for the first 200–300 km - the friction layer needs time to break in.

When does brake discs or drums need to be replaced?

Rear brake discs on Ε KODA Octavia serve on average 100–150 thousand km, but their condition must be checked every time the pads are replaced. Critical defects:

  • πŸ“ Disc thickness less than the minimum allowable (for example, for Octavia A7 this is 10 mm at par 12 mm).
  • πŸ” Deep furrows (more 0.5 mm) or cracks.
  • πŸŒ€ Disc runout (feels like vibration on the steering wheel when braking).

For drums, the replacement criterion is:

  • πŸ“ Inner diameter more 201.5 mm (denomination - 200 mm).
  • πŸ”§ Uneven wear (ovality more 0.1 mm).

When replacing discs or drums necessarily change the pads - the old ones will not provide a complete fit to the new surface. On Octavias with ESP may be required after replacing disks ABS sensor calibration (done through a scanner).

FAQ: Answers to frequently asked questions

Is it possible to replace the rear pads on an Octavia without a scanner if it has EPB?

Technically yes, but the handbrake will not work correctly. For a temporary solution, you can manually recess the caliper piston (by turning it clockwise), but after this necessarily visit the adaptation service. On some models (for example, Octavia A7 2017+) you can’t do without a scanner - block EPB will block the activation of the handbrake.

How much does it cost to replace rear pads at a service center?

Cost depends on brake type and region:

  • πŸ”§ Disc brakes: 1,500–2,500 rubles for the axle.
  • πŸ› οΈ Drum brakes: 2,000–3,000 rubles (due to the difficulty of disassembly).
  • πŸ”‹ Adaptation is paid additionally EPB (500–1,000 rubles).

Self-replacement allows you to save up to 70% of the cost.

How often should you check your rear pads?

Recommended interval - every 20 thousand km or when changing tires seasonally. On Octavias with DSG and frequent engine braking, the check should be carried out more often. Pay attention to:

  • πŸ”Š Extraneous sounds when braking.
  • πŸš— Pulling the car to the side.
  • πŸ“‰ Increased braking distance.
What should I do if the ABS light comes on after replacing the pads?

This is a typical problem for Octavia with ESP. Reasons:

  1. πŸ”Œ ABS sensor damaged when removing the caliper.
  2. πŸ”‹ Air entering the system (pumping required).
  3. πŸ“± Calibration failed after disconnecting the battery.

Solution: bleed the brakes, check the integrity of the sensors and reset the errors using a scan tool. If the lamp continues to light, contact service to diagnose the unit. ABS.

Is it possible to drive if the rear pads squeak?

Short term - yes, but not recommended. A squeak usually indicates:

  • πŸ›‘ Critical wear friction layer (less 2 mm).
  • πŸ”§ Ingress of sand or rust between the pad and the disc.
  • 🧴 No anti-squeak plates.

If the squeak is accompanied by vibration or poor braking, the pads need to be replaced. immediately.
