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:
- π 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 2β3 mm.
- π Car withdrawal to the side when pressing the brake pedal - may indicate uneven pad wear or a stuck caliper.
- π Increased pedal travel or its vibration. On models with ESP this sometimes results in an error
01314 β Brake Pressure Sensor. - π§ 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 30β50% 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:
- π ECE R90 certification β guarantee of compliance with European safety standards.
- π¦ Completeness: The box should contain pads, guide plates and caliper lube (if applicable).
- π§ System compatibility ESP β on Octavias with electronic handbrake (EPB) you need pads with a wear sensor.
β οΈ 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:
- π§ Set of sockets and keys: end on
13,15,17 mm, hexagon7 mm(for some models). - π¨ Balloon wrench and a jack (or lift).
- π§² Magnetic holder - so as not to lose the guide pins during disassembly.
- π§΄ Caliper Lubricant (for example, TRW PFG110 or Slipkote 220-R DBC).
- π 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:
- π§ Puller for tension springs (or needle nose pliers).
- π¨ Hammer and wooden spacer for careful removal of the drum.
β οΈ 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:
- Connect the scanner and run the command
Caliper adaptation. - Activate the handbrake in the on-board computer menu.
- Bleed the brakes (press the pedal 5-7 times until resistance appears).
If after replacing the pads the brake pedal becomes βsoft,β 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 1β1.5 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 3β4 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 10β15 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 βpullβ 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:
- π§ Incorrect tightening torque caliper bolts. On Octavia it is
30 Nmfor aluminum calipers and45 Nmfor cast iron. - π§΄ Using the wrong lubricant. For example, Litol or Solid oil are destroyed at high temperatures. Use only specialized compounds.
- π Forget to adapt EPB. Without this procedure, the handbrake will not work, and an error will appear on the dashboard
01314. - π 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:
- π No anti-squeak plates (they need to be moved from the old pads or bought new ones).
- π§Ό Contaminated brake disc. Before installing the pads, clean the disc with alcohol or a special cleaner (Brembo Cleaner).
After replacing the pads, avoid sharp braking for the first 200β300 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 100β150 thousand km, but their condition must be checked every time the pads are replaced. Critical defects:
- π Disc thickness less than the minimum allowable (for example, for Octavia A7 this is
10 mmat par12 mm). - π Deep furrows (more
0.5 mm) or cracks. - π Disc runout (feels like vibration on the steering wheel when braking).
For drums, the replacement criterion is:
- π Inner diameter more
201.5 mm(denomination -200 mm). - π§ 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 canβt 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:
- π§ Disc brakes: 1,500β2,500 rubles for the axle.
- π οΈ Drum brakes: 2,000β3,000 rubles (due to the difficulty of disassembly).
- π Adaptation is paid additionally EPB (500β1,000 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:
- π Extraneous sounds when braking.
- π Pulling the car to the side.
- π 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:
- π ABS sensor damaged when removing the caliper.
- π Air entering the system (pumping required).
- π± 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:
- π Critical wear friction layer (less
2 mm). - π§ Ingress of sand or rust between the pad and the disc.
- π§΄ No anti-squeak plates.
If the squeak is accompanied by vibration or poor braking, the pads need to be replaced. immediately.
