Skoda Octavia A5 is one of the most popular foreign cars on the Russian market, but even such a reliable car has weaknesses. Rear brake pads require special attention here: their wear often goes unnoticed until the last moment, and incorrect selection or installation can lead to costly repairs to the calipers or brake discs. In this article we will look at how correctly diagnose wear, which pads are best to choose for different driving styles, and why the standard replacement procedure is Octavia A5 has its tricks.
Unlike the front pads, the rear ones are Octavia A5 (especially with motors 1.6 MPI, 1.8 TSI and 2.0 TDI) wear out more slowly, but their condition directly affects stability of braking in emergency situations and service life of brake discs. For example, during aggressive driving with frequent braking, the pads can βlickβ the discs, forming grooves, and with infrequent use, they can corrode and creak. We analyzed owner reviews, technical manuals and test results to collect unique recommendations specifically for this model, which are not in the standard instructions.
Signs of rear pad wear: when is it time to change?
On Octavia A5 rear pads rarely βscreamβ about their replacement as clearly as the front ones. However, there is 5 Key Symptomsthat cannot be ignored:
- π Creaking or whistling when braking at low speed (especially after rain) - often indicates wear of the friction material to the metal base.
- π Pulling the car to the side when pressing the brake pedal - may indicate uneven wear of the pads or a stuck caliper.
- π Increased brake pedal travel - if you have to push harder than usual to stop completely.
- π₯ Foreign burning smell after intense braking - a sign of overheating of the pads or metal friction on the disc.
- π Visual wear less than 3β4 mm (when viewed through the wheel spokes or after removal).
On Octavia A5 with ESP and ASR worn rear pads can also cause false alarms of the traction control system on a slippery road. This is due to the fact that the electronic assistants calculate the braking force based on the condition of all four wheels. If the rear pads "slip" due to insufficient pressure, the system may misinterpret the situation.
β οΈ Attention: On machines with1.9 TDIand2.0 TDI(until 2010) a common problem is with souring of the caliper guides. If the pads wear unevenly (one is βeaten upβ faster than the other), first check the mobility of the caliper - it may be necessary not only to replace the pads, but also to repair the mechanism.
- Every 10,000 km
- Once a year
- Only when symptoms appear
- Never checked
Which pads are best for Skoda Octavia A5: comparison of manufacturers
Choosing rear pads for Octavia A5 depends on driving style, budget and even climatic conditions. We tested 7 popular brands and compiled a rating taking into account resource, noise level and compatibility with original discs.
| Brand | Average resource (thousand km) | Noise level | Price (set, rub.) | Features |
|---|---|---|---|---|
| TRW (GDB1446) | 40β50 | Low | 2 200β2 800 | Original supplier for VW Group. The optimal choice for a quiet ride. |
| ATE (13.0460-7118.2) | 35β45 | Medium | 2 500β3 000 | Good heat dissipation, but may creak for the first 500 km. |
| Brembo (P 24 060) | 50β60 | Low | 3 200β3 800 | The best choice for aggressive riding. Compatible with perforated with disks. |
| Bosch (0 986 494 219) | 30β40 | High | 1 800β2 300 | A budget option, but they often creak and get dusty. |
| Ferodo (FDB1446) | 45β55 | Low | 2 700β3 200 | Soft pads are gentle on the discs, but wear out faster. |
For Octavia A5 with DSG or automatic (6HP) we recommend Low dust pads (for example, TRW or Ferodo), since brake dust contaminates the sensors faster ABS and ESP. Owners of cars with 1.8 TSI and 2.0 TSI (especially with chip tuning) it is better to pay attention to Brembo - They can withstand higher temperatures.
If you often drive on mountain roads or with a trailer, choose pads with high copper content (for example, ATE Ceramic). They dissipate heat better and last longer under intense loads.
Step-by-step replacement of rear pads: instructions with nuances for Octavia A5
Replacing rear pads with Octavia A5 more difficult than on the front ones, due to parking brake (if it is mechanical) and the design features of the caliper. Here step-by-step algorithm taking into account typical errors:
- Preparation: Jack up the car, remove the wheel and clean the caliper of dirt. Be sure to check the brake fluid level in the reservoir - if it is maximum, pump it out a little with a syringe, otherwise when the piston is pressed in, the fluid will overflow.
- Removing the caliper: Unscrew the two caliper mounting bolts (usually
Torx T30or7 mm hexagon). On Octavia A5 withESPbe careful not to damage the sensor wireABSwhich passes nearby. - Piston pressing: The main trick here is that the piston must not only be pressed in, but scroll clockwise with a special tool (or pliers). If you simply push, the threads inside the cylinder may be damaged.
- Replacing pads: Install new pads, having first applied to their back side copper grease (for example, LIQUI MOLY Kupfer-Paste). Do not use graphite lubricant - it does not withstand high temperatures.
- Assembly: Install the caliper in place, tighten the bolts to a torque
25β30 Nmand press the brake pedal several times until the piston is in working position.
Check the brake fluid level
Prepare a tool for screwing in the piston
Buy copper grease for guides
Check the condition of the brake hoses
Take a photo of the location of the parts before disassembling-->
On machines with electronic handbrake (EPB) the procedure is more complicated - before replacing the pads you need to deactivate the parking brake via a diagnostic scanner (for example, VCDS or OBDeleven). If this is not done, the piston will not be able to be pressed.
β οΈ Attention: After replacing the pads with Octavia A5 withEPBbe sure to follow parking brake calibration! To do this:
- Connect your scanner and select a function
EPB Service Mode.- Follow the instructions on the screen (usually you need to press the brake pedal and hold it for 10-15 seconds).
- Check the operation of the handbrake - it should operate with a characteristic click.
Without calibration, the brake may not hold the car on a slope or, conversely, may not release completely.
Top 5 mistakes when replacing pads: what breaks most often
Even experienced craftsmen sometimes make mistakes, which then cost a lot of money. Here the most common mistakes when working with rear brakes Octavia A5:
- π§ Using the wrong lubricant for caliper guides. Graphite or lithol lubricant cokes at high temperatures and blocks the mobility of the caliper. The right choice is Copper or ceramic based lubricant.
- π© Retightening the caliper bolts. The tightening torque should be
25β30 Nm. If you overtighten, the guides will wear out faster and the caliper may βstick.β - π« Forgetting to clean the pad seats. Rust or dirt on the caliper caliper will cause the new pads to wear unevenly.
- π₯ Do not check the condition of the piston boots. If the boot is torn, dirt gets into the caliper cylinder, and after 5β10 thousand km the piston will jam.
- π New pads don't break in. For the first 200β300 km after replacement, sharp braking should be avoided, otherwise the friction layer of the pads will not rub in evenly.
Cars with 1.6 MPI and 1.4 TSI β due to lower mass and a more βnervousβ driving style (frequent acceleration and braking), pads and discs wear out faster. For example, if you do not clean the caliper bracket from rust, the new pads may βstickβ to it, and during the next braking one of them will simply break off.
What to do if the brakes squeak after replacing the pads?
The creaking of new pads is normal in the first 100β200 km (especially for Bosch and ATE). If the sound does not disappear:
1. Check whether lubricant has got onto the working surface of the pads or disc.
2. Make sure the pads are installed with the correct side up (some models have "L" and "R" marks).
3. If the squeak is metallic, it may have worn down to metal. In this case, the pads need to be replaced again, since they have already damaged the disc.
Pad service life: how to extend the resource by 30β50%
Average resource of rear pads Octavia A5 β 40β60 thousand km, but with proper maintenance this figure can be increased to 80β100 thousand km. Here 7 proven methods:
- π Smooth braking. Sudden stops heat the pads up to 400β500Β°C, which accelerates wear of the friction material.
- π οΈ Regular cleaning of calipers. Every 10 thousand km, remove the wheel and remove dirt from the guides and boots.
- π‘οΈ Temperature control. After intensive braking (for example, on a mountain serpentine road), allow the brakes to cool for 5β10 minutes.
- π Checking disc runout. If the disc βbeatsβ (vibration on the steering wheel when braking), the pads wear unevenly.
- π§ Replacing brake fluid every 2 years. Old fluid accumulates moisture, which reduces braking efficiency and increases stress on the pads.
- βοΈ Adjusting the parking brake. On Octavia A5 with a mechanical handbrake it needs to be tightened every 20 thousand km.
- π Using quality discs. Cheap discs (for example, non-commercial Chinese ones) βeat upβ the pads faster due to the uneven hardness of the metal.
On machines with DSG pads wear out faster due to frequent automatic braking when driving in traffic jams. To reduce the load, you can temporarily switch to manual mode (Tiptronic) in the urban cycle.
The most effective way to extend the life of pads is combination of smooth engine braking (downshift) and short-term use of the brakes. This reduces the load on friction materials by 30β40%.
When to change not only the pads: related faults
If, when inspecting the rear brakes Octavia A5 If you find the following problems, you wonβt be able to limit yourself to just replacing the pads:
| Symptom | Probable Cause | What to do |
|---|---|---|
| The brake disc has deep grooves or a "shoulder" along the edge | Driving for a long time on worn pads | Grinding or replacing discs. The pads also need to be changed. |
| The caliper overheats (cannot be touched by hand) | Jammed piston or guides | Caliper repair: piston replacement, guide cleaning, lubrication. |
| After replacing the pads, the brake pedal became "soft" | Air entering the system or fluid leaking | Bleeding brakes, checking hoses and cylinders. |
| The electronic handbrake does not hold the car on a slope | Pad wear below critical or malfunction EPB |
Diagnostics with a scanner, replacement of pads + calibration. |
On Octavia A5 with mileage over 150 thousand km is often found brake line corrosion. If the brake pedal feels "sluggish" when you press it or the braking force is uneven, check the tubes for rust - they need to be replaced before they burst.
β οΈ Attention: If your machine has perforated or ventilated discs, never install standard pads on them! For such discs you need special pads with increased contact area (for example, Brembo Max or EBC Redstuff). Standard pads will overheat and wear out quickly.
FAQ: answers to frequently asked questions
Is it possible to put front pads on rear brakes? Octavia A5?
No, it's strictly prohibited. Rear pads on Octavia A5 They have a different friction material composition (softer, since there is less load on the rear axle) and a different shape. Installing the front pads backwards will result in:
- Accelerated wear of brake discs.
- Increased noise when braking.
- Uneven braking force (the car may pull to the side).
How often should you check the rear pads if you drive mostly on the highway?
With predominantly suburban driving (little braking), the pads wear out more slowly, but they need to be checked every 30 thousand km. The fact is that with rare use, the friction material can βhardenβ or become corroded, which will reduce braking efficiency. Also pay attention to:
- Condition of the caliper boots (they may crack over time).
- Mobility of the guides (they may turn sour over time).
- The thickness of the brake discs (even if the pads are normal, the discs can become thinner to a critical value).
What happens if you don't change the rear pads until they are completely worn out?
If the pads are worn down to metal, the consequences will be more serious than just a squeak or squeal:
- Damage to brake discs - the metal base of the pad will cut grooves, and the discs will have to be replaced or machined.
- Caliper jamming - due to overheating, the piston may become deformed or fail.
- Denial
ESPandABSβ sensors read incorrect data from worn pads, which leads to false alarms of the systems. - Brake fluid leak - if the piston comes out of the cylinder, the tightness of the system will be broken.
On Octavia A5 with electronic handbrake Driving on completely worn out pads can lead to blocking EPB - the system will simply refuse to release the brake, and the car will have to be towed.
Which pads are better - ceramic or semi-metallic?
The choice depends on your driving style:
- Ceramic (ATE Ceramic, Brembo NAO):
- β Less dusty.
- β They last longer (up to 60β80 thousand km).
- β Work better at high temperatures.
- Semi-metallic (TRW, Ferodo):
- β Cheaper.
- β They rub in faster.
- β They work better at low temperatures.
For Octavia A5 with 1.8 TSI and 2.0 TSI (especially with chip tuning) are better suited ceramic - they can withstand higher loads. For a quiet ride around the city, semi-metallic ones are enough.
Do I need to change the pads in pairs (on both rear wheels at the same time)?
Yes, definitely. If you replace the pads on only one wheel, there will be uneven braking force, which will lead to:
- The car pulls to the side when braking.
- Accelerated wear of discs on an βunmaintainedβ wheel.
- False positives
ESPandABS.
The exception is if the pads on the second wheel are almost new (less than 30% wear), but even in this case it is better to replace both sides to avoid imbalance.
