Rear brake pads on Ε KODA Octavia A7 (including restyled version FL) is a critical safety feature that is often overlooked until a squeaking noise occurs or the wear warning light trips. Unlike the front pads, the rear ones wear out more slowly, but their condition directly affects the stability of braking, especially on wet roads or during sharp maneuvers.
In this article we will look at everything the owner needs to know. Octavia A7: how to determine the wear of the rear pads without disassembling, what brands (TRW, ATE, Brembo, Bosch) offer the best price-quality ratio, and why the original pads VW Group (article 5Q0698451) do not always justify their cost. And also - step-by-step instructions for replacement with photos, typical mistakes and answers to frequently asked questions.
Signs of wear on the rear brake pads on an Octavia A7
Rear pads on Octavia A7 (with both disc and drum brakes on basic versions) rarely wear evenly. The first symptoms of a problem are often ignored until a metallic grinding noise appears or the dashboard light comes on. Here are the key signs that it's time to check your rear brakes:
- π Creaking or whistling when braking at low speed (especially after rain). This is a signal that the friction layer has been worn down to metal.
- π Car withdrawal to the side when pressing the brake pedal - may indicate uneven pad wear or a stuck caliper.
- π‘ Brake light is on on the tidy (if pads with a wear sensor are installed). On Octavia A7 this is a mistake
03286or03288. - π Increased pedal travel or βsoftβ braking is a sign that the pads do not provide sufficient pressure to the disc.
Feature Octavia A7 β rear brake discs often become βovergrownβ with a bead along the edge due to uneven wear. If the shoulder exceeds 1 mm, the pads no longer contact the disc over the entire area, which reduces braking efficiency by 30-40%. You can check this without removing the wheel: just look through the spokes at the inside of the disc.
β οΈ Attention! On versions with electromechanical parking brake (EPB) wear of the rear pads can lead to spontaneous operation of the handbrake due to incorrect operation of the sensors. If after replacing the pads EPB not calibrated - adaptations need to be reset viaVCDSorODIS.
- Once every 10,000 km
- Only when they creak
- At every maintenance
- Never checked
Which pads to choose: original vs analogues
Original rear pads for Ε KODA Octavia A7 (article 5Q0698451 for versions with EPB and 5Q0698151 for a mechanical handbrake) are produced TRW or ATE under the brand VW Group. Their average price is 4,500β6,000 rubles per set. But are they better than their analogues?
| Brand | Article | Price (set), rubles | Features | Rating (based on reviews) |
|---|---|---|---|---|
| VW/Skoda OEM | 5Q0698451 |
5 800 | Original, low dust, optimized for EPB | 4.8/5 |
| TRW | GDB3436 |
3 200 | Soft friction material, little noise, but wear out faster | 4.6/5 |
| ATE | 13.0460-7206.2 |
3 800 | Long service life, but may creak for the first 500 km | 4.7/5 |
| Brembo | P68055 |
4 100 | Aggressive friction composition, suitable for sporty driving style | 4.5/5 |
| Bosch | 0986494793 |
2 900 | Budget option, average resource, can get dusty | 4.3/5 |
If your Octavia A7 used mainly in the city, the optimal choice is ATE or TRW. Better suited for active driving Brembo, but they wear out the discs faster. Important: on versions with EPB, you cannot install pads without a wear sensor - this will lead to an error in the control unit and the inability to activate the parking brake.
When purchasing, check:
- π¦ Presence of wear sensor (if it was on the old pads). On Octavia A7 The sensor is built into the internal block.
- π§ Complete set: The box should contain guide plates, springs and caliper grease.
- π Certificate of Conformity (for example,
ECE R90). Counterfeits often have no markings.
If you choose between ATE and TRW, pay attention to climatic conditions. TRW perform better in cold weather (less susceptible to βstickingβ), and ATE more stable in hot weather.
Step-by-step instructions for replacing rear pads
Replacing rear pads with Ε KODA Octavia A7 more difficult than the front ones due to integration with the system EPB (if there is one). You will need:
- π§ Jack and supports (or lift).
- π¨ Set of heads (especially
T30andT40for EPB). - π§΄ Caliper Lubricant (Slipkote or TRW PFG110).
- π Diagnostic scanner (
VCDS,OBDeleven) to discharge EPB.
Step 1: Preparing and removing the wheel
Raise the car, remove the wheel and clean the caliper of dirt. On versions with EPB before removing the pads necessarily disable the parking brake via the menu MMI β Settings β Service β Electronic. handbrake β Off or using a scanner.
Step 2. Removing the caliper
Unscrew the two caliper mounting bolts (usually 13 mm or T40). On Octavia A7 with EPB First you need to unscrew the handbrake drive motor (bolt T30), otherwise the caliper will not be removed. Carefully hang the caliper on the wire so as not to damage the hose.
Step 3. Replacement of pads
Remove the old pads and guide plates. Clean any rust from the seats and apply a thin layer of lubricant to the contact points of the new pads. Install the pads, making sure the wear indicator (if equipped) is positioned correctly.
Make sure that the caliper piston is completely recessed|Check the integrity of the guide boot|Apply lubricant to the back of the pads|Install the pads so that the wear sensor is on top-->
Step 4: EPB Assembly and Calibration
After installing the caliper and wheel, you must necessarily carry out calibration EPB through a diagnostic scanner. Without this, the handbrake will not work correctly. Commands for VCDS:
[Select][44 - Steering Assist]
[Security Access - 40168]
[Basic Settings]
[Group 001]
Press and hold the brake pedal until the procedure is completed (about 30 seconds).
β οΈ Attention! If after replacing the pads EPB not calibrated, check:
- Correct installation of the wear sensor (it must be connected to the connector).
- The integrity of the wiring from the caliper to the control unit (often rubs against the lever).
- Battery charge level (below
12.5 Vcalibration will not work).
What to do if after replacing the pads the brakes are βwobblyβ?
This is normal for the first 100β200 km - the new pads grind into the disc. If the problem persists longer:
1. Check whether the caliper is warped (it should move freely along the guides).
2. Make sure that the caliper piston is not jammed (it should move out evenly when you press the pedal).
3. Bleed the brake system (air may have entered during replacement).
Typical replacement mistakes and how to avoid them
Even experienced mechanics make mistakes when working with rear brakes. Octavia A7. Here are the most common:
- π§ Didn't reset the EPB before removing the caliper β the handbrake drive motor breaks when you try to release the pads.
- π§΄ Used the wrong lubricant (for example, Litol or graphite) β the caliper sticks after 5,000 km.
- π EPB has not been calibrated β the handbrake does not hold or activates spontaneously.
- π Installed pads without anti-squeak plates β constant whistle when braking.
Another common problem is uneven pad wear after replacement. This happens due to:
- π Jammed caliper guides (needs to be cleaned and lubricated with each replacement).
- π Warped brake disc (check the disc runout with an indicator - the tolerance is no more than
0.05 mm). - π§ Incorrect installation of springs (they should fix the pads, but not pinch them).
Critical error: ignoring the condition of the brake hoses. On Octavia A7 after 100,000 km, rubber hoses lose their elasticity, which leads to βwedgingβ of the caliper. When replacing pads, always check the hoses for cracks and swelling!
If after replacing the pads the brake pedal becomes βsoft,β most likely the caliper piston is not fully recessed. Use a special tool to press in the piston (on versions with EPB it must be rotated clockwise at the same time).
When to change brake discs and pads
On Ε KODA Octavia A7 Rear brake discs last on average 120,000β150,000 km, but their condition must be checked every time the pads are replaced. Critical indicators for replacement:
- π Disc thickness less
8.4 mm(denomination for new ones -10 mm). - π Edge collar more
1.5 mm. - π Deep grooves or cracks (more
0.5 mm). - π₯ Disk overheating (blue discoloration of the metal indicates that the temperature has been exceeded).
If the discs are still normal, but have minor grooves on them, they can be sharpened. However, on Octavia A7 with EPB Grooving the discs without removing the caliper is impossible - complete dismantling of the brake mechanism is required.
| Symptom | Reason | Solution |
|---|---|---|
| Vibration when braking | Disc deformation (runout more than 0.1 mm) |
Grinding or replacing discs |
| Creak of new pads | Missing anti-squeak plates or incorrect installation | Reinstall the pads with plates and lubricant |
| The handbrake doesn't hold | Uncalibrated EPB or worn pads | Calibration through diagnostics or replacement of pads |
| Uneven pad wear | Stuck caliper or guides | Cleaning and lubricating the guides, replacing the caliper if necessary |
When replacing disks with Octavia A7 It is recommended to install original (5Q0615601) or analogues from ATE (24.0120-0179.1) or Brembo (09.9606.11). Cheap disks (for example, Avantech) often come with an uneven metal structure, which leads to vibrations.
Cost of service replacement vs self-repair
Cost of replacing rear brake pads Ε KODA Octavia A7 in service varies from 2,500 to 6,000 rubles (excluding the cost of spare parts). The spread depends on:
- π§ Type of braking system: s EPB work is 30β40% more expensive.
- π Region: in Moscow and St. Petersburg the average price is 20% higher.
- π Diagnostic needs (if error reset is required EPB).
Breakdown of work costs (for Octavia A7 1.6 TDI with EPB):
- π§ Replacing pads (without EPB): 1 500β2 000 β½.
- π§ Replacing pads (with EPB): 3 000β4 000 β½.
- π§ Disc groove: 1 000β1 500 β½ per disc.
- π§ Replacing brake discs: 2 000β3 000 β½ (set).
- π Diagnostics and EPB reset: 500β1 000 β½.
Replacing it yourself will only cost the cost of the pads (3 000β6 000 β½) and, if necessary, disks (5 000β8 000 β½). However, without experience and tools (especially for EPB) the risk of errors is high. For example, incorrect calibration of the handbrake can lead to its failure at the most inopportune moment.
β οΈ Attention! If you decide to change the pads yourself, keep in mind:
- On versions with EPB It is impossible to do without a diagnostic scanner - the handbrake will not work.
- When replacing disks, be sure to use new mounting bolts (they are disposable!).
- After replacing the pads, avoid sudden braking for the first 200 km - the friction material needs to get used to.
Frequently asked questions about Octavia A7 rear brake pads
Is it possible to install pads without a wear sensor if it is broken?
No, on versions with EPB This will lead to an error in the control unit and the inability to activate the parking brake. If the sensor is damaged, it must be replaced separately (part number 5Q0987771). On versions with a mechanical handbrake, you can do without a sensor, but then you will not receive wear warnings.
How long do rear pads last on Octavia A7?
Service life depends on driving style and conditions:
- π City mode: 60,000β80,000 km.
- π£ Route: up to 100,000 km (due to less braking).
- π Highlands: 30,000β50,000 km (due to constant loads).
On vehicles with DSG The pads wear out faster due to a more aggressive engine braking algorithm.
Why do my brakes squeak after replacing the pads?
Causes of squeaking and solutions:
- π New pads are breaking in (normal for the first 200β300 km).
- π§΄ No anti-squeak lubricant on the back side of the pads - apply TRW PFG110.
- π§ Anti-squeak plates are installed incorrectly - reinstall them.
- π Low quality friction material (typical for cheap pads Fenox or Avantech).
If the squeaking persists, try sharpening the discs or replacing the pads with a different brand.
How to reset the EPB error after replacing the pads?
To reset an error EPB on Octavia A7 need a diagnostic scanner (VCDS, OBDeleven, Launch). Procedure:
- Connect the scanner to the connector
OBD-II. - Select block
44 β Steering Assist(or53 β Parking Brakeon some versions). - Go to
Basic Settings(Basic settings) βGroup 001. - Press and hold the brake pedal until the procedure is completed (about 30 seconds).
- Clear errors from the unit's memory.
It is impossible to reset the error without a scanner!
Which pads are best for Octavia A7 with 1.8 TSI engine?
For 1.8 TSI (especially with DSG) pads with a high coefficient of friction are recommended:
- ATE 13.0460-7206.2 β optimal balance of wear resistance and braking force.
- Brembo P68055 - the best choice for active driving, but the discs wear out faster.
- TRW GDB3436 β soft, little noise, but the resource is 20% lower.
Avoid budget brands (Bosch, Ferodo) - they are not designed for high loads typical of turbo engines.
