The braking system is a critical safety element of any vehicle, and ล koda Kodiaq is no exception. As the mileage accumulates, the friction linings wear out, which requires timely replacement to maintain braking efficiency. Ignoring wear and tear can result in damaged brake rotors, which can lead to much more 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 the front wheels, where the piston is simply pressed in, here it is necessary to properly prepare the caliper so as not to damage the electric motor of the mechanism. The correct sequence of actions will ensure reliable operation of the brakes and extend the service life of the components.
Symptoms of wear and diagnostics of the brake system
The need for replacement can be determined not only by on-board computer data, but also by indirect signs of operation. Drivers often notice a specific sound when braking, which becomes louder as the friction material wears away. This metallic grinding noise occurs when the wear indicator comes into contact with the disc.
In addition to audible alerts, it is worth paying attention to the behavior of the car when you sharply press the pedal. If the car begins to pull to the side, this may indicate uneven pad wear or jammed caliper guides. Also, visual inspection through the spokes of the disc allows you to evaluate the thickness of the friction lining without removing the wheel.
It is important to understand that the wear indicator on ล koda Kodiaq can be either mechanical or electrical. An electronic sensor is triggered when a critical thickness is reached, lighting up an icon on the instrument panel. However, you should not rely only on the light bulb, since the sensor may fail or be disabled during a previous repair.
- ๐ The appearance of a metallic squeak or grinding noise during light braking
- ๐ Increasing brake pedal travel or having to press harder on the brake pedal
- ๐ The brake wear warning icon lights up on the dashboard
โ ๏ธ Caution: If you hear a loud metallic grinding noise, stop using the vehicle immediately. Delay can lead to the destruction of the brake disc and failure of the braking system at a critical moment.
Preparing tools and selecting consumables
To perform the work efficiently, you will need a set of specialized tools, since a standard set may not be suitable for pressing the piston, taking into account the electronic drive. It is necessary to have a diagnostic scanner or a special adapter to move the piston to the service position. Without this step, it will be impossible to install new pads, as they simply will not fit into place.
The choice of pads themselves plays a key role in driving comfort and safety. For ล koda Kodiaq It is recommended to use original spare parts or proven analogues from leading manufacturers, such as TRW, Ate or Textar. Cheap non-original products often create a lot of dust, quickly wear out the discs and can produce an unpleasant squeak.
Also, be sure to have cleaning supplies and lubricants ready. A special high-temperature lubricant for guide calipers and pad contact pads is required. Do not use regular lithium grease or WD-40 as they can destroy the rubber seals and cause the mechanism to jam.

Step-by-step instructions for replacing rear pads
Begin work by placing the vehicle on a level surface and applying the handbrake. For safety, be sure to place wheel chocks under the front wheels. Raise the rear of the car with a jack and place it on a secure stand, as working on a jack alone is prohibited by safety regulations.
Before removing the wheel, the electronic handbrake must be reset to service mode. This can be done through a diagnostic scanner by connecting to the ABS unit, or through the instrument cluster if the car is equipped with the corresponding function. After activating the mode, the caliper piston will automatically move back, making room for new pads.
Next, unscrew the caliper guides, remove it and put it in a safe place, hanging it on a wire so as not to damage the brake hose. Old pads are easily removed from the bracket. Be sure to clean the caliper seats of dirt and rust using a wire brush and brake cleaner.
โ๏ธ Preparing to replace pads
Install new pads into the bracket, having previously lubricated the contact pads with a special paste. It is important not to lubricate the working surface of the pad itself. After installing the bracket onto the disc, tighten the guides to the recommended torque using a torque wrench. This will prevent squeaks and vibrations when braking.
- ๐ง Carefully remove the old pads and clean the bracket from dust
- ๐งผ Apply special lubricant to the back of the new pads
- ๐ Check the thickness of the brake disc before installing new elements
- ๐ฉ Tighten the caliper guides with a torque wrench
Nuances of the service mode
If the battery is disconnected or there is no scanner, the piston may not return to its original position. In this case, you will need a mechanical adapter to press in the piston, which takes into account its screw thread, characteristic of electronic calipers.
โ ๏ธ Caution: Never press the brake pedal while the calipers are in service mode or new pads are not installed. This can cause the piston to come out of the housing and cause complete loss of brake fluid.
Technical nuances and working with the electronic handbrake
Electronic parking brake on ล koda Kodiaq requires special attention during maintenance. The mechanism is driven by an electric motor built into the rear caliper, which has a helical gear. If you try to mechanically press such a piston with a conventional tool, you can break the gears inside the motor, which will require an expensive replacement of the entire caliper.
The correct algorithm of actions involves the use of diagnostic equipment to put the mechanism into replacement mode. In this mode, the electric motor moves the piston to the maximum distance required to install the new pad thickness. After completing the work, you must connect the scanner again to bring the mechanism into working position.
If you do not have access to professional equipment, there are mechanical adapters that simulate the rotation of the piston when it is pressed in. However, the use of such adapters requires extreme care and knowledge of the design of a particular caliper. An error in the direction of rotation may damage the thread.
Before starting work, be sure to disconnect the battery if you are using a diagnostic scanner to avoid voltage surges in the on-board network, which could damage the ABS unit or handbrake electronics.
After installing new pads and assembling the wheel, be sure to carry out the adaptation procedure. In some cases, the on-board computer may not immediately detect the new thickness of the brake elements, and the wear sensor will continue to show an error. Rebooting the system or performing several braking cycles at varying intensities will usually resolve this issue.
The electronic handbrake requires mandatory switching to service mode via a scanner or a specialized adapter before mechanical intervention.

Quality check and testing of new elements
After completing the work and lowering the vehicle to the ground, it is necessary to check the operation of the brakes in place. Press the brake pedal all the way down several times until the pistons are in the correct position relative to the new pads. Make sure that the pedal is elastic and does not fall, and the car does not pull to the side when pressed.
For the first 200-300 kilometers, you should follow a gentle running-in regime. Avoid sudden and strong braking so that the friction material gets used to the surface of the disc. This will ensure maximum efficiency of the braking system and prevent overheating of components during the initial period of operation.
Remember that proper running-in of new pads directly affects the service life of brake discs and overall driving safety. Ignoring this step can lead to thermal cracks on the discs and uneven wear of friction pairs.
- ๐ For the first 50 km, avoid sudden stops and emergency braking.
- ๐ก๏ธ Monitor the temperature of the disks, do not allow them to overheat
- ๐ After 500 km, check the tightness of the guide calipers
Frequently asked questions about Kodiaq brake service
Can I replace only the front pads or just the rear pads?
Technically, it is possible to replace one axle, but experts strongly recommend replacing the pads as a set on one axle (both wheels). This ensures uniform braking and prevents the vehicle from skidding during an emergency stop due to differences in the coefficient of friction.
How often do you need to change the rear pads on a ล koda Kodiaq?
The service life of the rear pads is usually higher than the front ones and ranges from 40,000 to 80,000 km. The exact period depends on driving style, operating conditions (city or highway) and the quality of consumables used. Regular visual inspection is the most reliable method of control.
What to do if a squeak appears after replacement?
Creaking can occur due to lack of lubrication on the contact pads, poor-quality pads, or the presence of rust on the bracket. Check for special high-temperature grease on the back of the pads and where they contact the guides. If the problem persists, you may need to replace the pads with a better brand.
Do I need a scanner to replace rear pads?
Yes, for ล koda Kodiaq With electronic handbrake a scanner or special adapter is required. Without switching the caliper to service mode, it is impossible to press the piston in without damaging the electric motor mechanism. Mechanical pressing without unlocking the electronics is strictly prohibited.
Can I use DOT 4 brake fluid instead of DOT 5.1?
In the braking system ล koda Kodiaq Typically a DOT 4 or DOT 5.1 fluid is used. These fluids are compatible, but it is better to follow the manufacturer's recommendations specified in the service book. DOT 5 (silicone) is not compatible with other types and should not be used.
