Regular maintenance of the brake system is the key to safe driving. Skoda Kodiaq. Rear brake pad wear is an inevitable process that directly affects stopping performance and the condition of expensive brake discs. Ignoring wear sensor signals or a characteristic squeak can lead to critical damage to the caliper and the need for expensive repairs.
The procedure for replacing rear pads on this crossover has its own characteristics associated with the design of the electronic parking brake. Unlike classic mechanical drives, a mandatory procedure for resetting the caliper piston through the diagnostic interface or special modes is required here, otherwise physical pressing is impossible without breaking the mechanism.
In this article, we will look in detail at what tools are needed for the job, how to properly prepare the car, and in what sequence to perform the operations. You will learn about the intricacies of choosing consumables and gain a clear understanding of how to avoid mistakes that beginners often make when working with suspension and brakes.
Preparing tools and selecting consumables
Before you begin lifting the car, you must make sure that you have all the necessary tools and components. For working with calipers Skoda Kodiaq a standard set of keys may not be sufficient, especially if you plan to do everything yourself in a garage environment.
The key element is a set of sockets and ratchets, including specific sizes for the wheel bolts and caliper guides. You will also need a special tool to press the piston in, as it doesn't just move linearly, but has a threaded connection that requires rotation when pressed.
- π§ Socket set (including 17mm for wheels and 7mm for guides)
- π Caliper piston wrench (or universal set)
- 𧴠Brake fluid and a clean rag to remove dirt
- π Torque wrench for proper bolt tightening
When choosing new pads, you should pay attention to original spare parts under the brand Skoda or high-quality analogues from manufacturers like TRW, ATE or Brembo. You should not save on this unit, as cheap materials can quickly wear out, cause vibrations or overheating of the disks.
Be sure to check the condition of the brake discs before installing new pads. If they have deep risks, wear or cracks, replacing the pads alone will not solve the problem, but will only worsen the wear of the new parts.
β οΈ Caution: Never use old pads as a size reference when choosing new ones. Manufacturers can change the geometry and thickness of the linings even within the same car model, depending on the year of manufacture and configuration.
It is also recommended to prepare lubricant for the caliper guides in advance. Use only special heat-resistant lubricants intended for brake systems, since ordinary solid oils or lithols can destroy rubber boots.
Piston reset technology and operation with electronic handbrake
The most difficult step when replacing rear pads is Skoda Kodiaq is to return the caliper piston to its original position. The rear caliper design is equipped with an electromechanical drive that blocks mechanical indentation of the piston in normal mode.
If you try to compress the piston with a clamp or other tool without first putting the electronics into service mode, you are guaranteed to break the drive mechanism or piston, which will require you to replace the entire caliper assembly.
To perform the job safely, the system must be placed in maintenance mode. This can be done in two ways: through a diagnostic scanner or through a sequence of actions with the brake pedal and handbrake, if the car supports such a function without equipment.
- π Using a diagnostic scanner (VAS, OBDLink, Delphi) to activate the mode
- π Removing the wheel and opening the brake caliper cover before the procedure
- π§ Disconnecting the caliper motor connector in the absence of a scanner
When using diagnostic equipment, connect the adapter to the OBDII connector, run the program and select the section Brake system β Electromechanical parking brake β Special functions β Piston shift. After confirmation, the system will automatically retract the piston.
If you do not have access to a scanner, some models allow you to perform the procedure manually: with the ignition on, press and hold the brake pedal while raising and lowering the electronic handbrake lever until you hear a characteristic click, after which the piston should move out. However, this method does not work on all firmware versions.
- Diagnostic scanner
- Special key
- Manually without equipment
- I contact the service
What to do if the electric motor connector is damaged?
If the connector is damaged or missing, mechanical pressing of the piston is impossible. In this case, it is necessary to replace the electric motor or the entire caliper, or use a special adapter that is connected directly to the motor contacts to supply reverse voltage.
Once the piston is completely retracted into the housing, you can begin to remove the old caliper and replace the pads. Make sure the piston is in its rearmost position to allow the new pad to slide into place.
Step-by-step instructions for dismantling and installation
Begin work by raising the vehicle safely. Use a reliable jack and be sure to install stands under the body to eliminate the risk of the car falling. Remove the rear wheel and clean the caliper of dirt and dust.
Unscrew the two guide bolts securing the caliper bracket. They are usually 7mm in size with a hex socket or socket head. Carefully remove the bracket without damaging the brake hose, and hang it on a wire or hook so that it does not hang on the hose.
βοΈ Preparing to remove the caliper
Remove the old brake pads from the guides. Watch out for metal spring clips that may stick to the disc or bracket. Carefully remove them and clean the seats if necessary.
Before installing new pads, apply a thin layer of special lubricant to the back of the pads (where metal touches metal) and to the guide brackets. This will ensure free movement of the caliper and prevent squeaks.
Install the new pads into the guides, making sure they fit snugly and have no play. Reinstall the caliper bracket and tighten the guide bolts to the recommended torque, usually around 30 Nm, but check the specifications for your modification.
Before final tightening of the guide bolts, check that the boots on the bolts are not twisted or damaged, as this will cause the caliper to jam.
After installing all components, be sure to return the piston to its working position. If you used a scanner, follow the procedure to exit the service mode. If you worked manually, make sure that the electric motor is reconnected and working properly.
β οΈ Attention: After replacing the pads, before starting to drive, you must press the brake pedal firmly several times so that the pistons reach their working stroke and press the pads against the disc. Otherwise, the first time you brake, you will be left without brakes.
Typical errors and operating nuances
Many car owners make the mistake of ignoring the condition of the brake discs every time they replace the pads. Even minor disc wear can cause new pads to not work correctly, causing the steering wheel to wobble or vibrate when braking.
Another common problem is incorrect installation of the caliper guides. If they are twisted or lubricated with the wrong compound, the caliper can βstickβ, which will lead to overheating of the brakes, their boiling and loss of efficiency.
It is also important to remember the wear indicator. On Skoda Kodiaq it is often built into the block itself or is a separate element. If the wear indicator has tripped, it must be replaced along with the pads, otherwise the error message on the dashboard will remain on constantly.
- β Ignoring the replacement of guides when they are loose
- β Using a universal lubricant instead of a specialized one
- β Forgotten boots on guide bolts
Proper maintenance and proper selection of materials will significantly extend the life of your brake system. Do not skimp on the quality of consumables, since the safety of passengers and the driver depends precisely on the serviceability of these components.
| Parameter | Meaning | Comment |
|---|---|---|
| Guide tightening torque | 30 Nm | Use a torque wrench |
| Wheel bolt tightening torque | 120 Nm | For wheels R17-R19 |
| Guide lubrication type | Silicone/ceramic | It is prohibited to use lithol |
| Minimum disc thickness | 22 mm (depending on model) | Check the markings on the disc |
When operating the vehicle after replacement, pay attention to the braking behavior. If the pedal becomes soft or there are strange sounds, this may indicate the presence of air in the system or incorrect installation of parts.
Comparison of original and analog components
When choosing between original pads Skoda and their analogues, it is worth considering not only the price, but also the composition of the friction material. Original products undergo strict certification and guarantee compatibility with ABS and ESP electronics.
High-quality analogues from well-known brands often offer similar characteristics, but may differ in service life or noise level. Cheap Chinese copies usually contain a lot of metal, which accelerates disc wear and causes severe squeaking.
If you often drive in city mode with frequent acceleration and braking, it is better to choose ceramic or low-metallic pads, which generate less dust and do not overheat. For country trips, standard organic formulations are suitable.
Original pads guarantee perfect compatibility with electronics, but high-quality analogues from trusted brands can be cheaper and not inferior in performance if selected correctly.
The table below shows approximate differences in the characteristics of the different types of pads that can be found on the market.
| Pad type | Service life | Impact on disk | Price |
|---|---|---|---|
| Original Skoda | High | Minimum | High |
| Premium analogues | High | Low | Average |
| Budget analogues | Medium | High | Low |
You should not chase the lowest price, since savings on brakes may result in the need to replace discs and calipers, which will be many times higher than the cost of high-quality pads.
