Rear brakes on a car Škoda Octavia A5 often become a cause of concern for owners due to their specific design, which combines a mechanical drive and an electronic control system. Unlike the front wheels, where wear occurs faster, the rear pads last longer, but replacing them requires a more careful approach to the procedure and selection of components. Incorrect installation or the use of low-quality parts can lead to jamming of the caliper or overheating of the drum.
Model owners Octavia A5 There are two main types of brake systems on the rear axle: disc and drum. The choice of a specific type depends on the year of manufacture, engine size and vehicle equipment. It is important to understand that each configuration has its own service considerations that must be taken into account when planning maintenance and repairs.
Design features of the rear axle brake system
Rear brake design Škoda Octavia A5 has its own unique features that directly affect the choice of spare parts and replacement method. Most basic and mid-range trims are equipped with drum brakes, which are highly reliable and durable. However, on more powerful versions or in rich trim levels you may find disc brakes with a floating caliper.
Particular attention should be paid to the parking brake (handbrake) mechanism. Drum brakes use a separate lever inside the drum, while disc brakes use a screw mechanism built into the caliper piston. This difference is critical when replacing pads, as it requires different tools and approaches to compressing the piston.
Many owners underestimate the importance of lubricating guides and contact surfaces. If this step is neglected, abnormal noise or uneven wear may occur. brake linings. Regular checks of the condition of the boots and the integrity of the brake hoses are also included in the mandatory list of works when servicing the rear wheels.
Symptoms of wear and condition diagnosis
Determine when replacement is necessary rear brake pads, is possible based on a number of characteristic features that appear during operation. The most obvious signal is the appearance of a specific squeak or squeal when you press the brake pedal. This sound is often caused by a wear indicator that comes into contact with the disc or drum when it reaches a critical thickness.
In addition to audible alerts, you should pay attention to the behavior of the car when braking. If the car starts to pull to one side or the brake pedal becomes less responsive, this could indicate uneven pad wear or a seized caliper piston. In the case of drum brakes, a symptom of wear may be an increase in the free play of the handbrake lever, which does not recover even after tightening.
Visual examination is the most accurate method of diagnosis. Removing the wheel, you can estimate the thickness of the friction layer. If the lining is thinned to 2-3 mm, the operation of the car becomes dangerous and requires immediate intervention. Ignoring these signs can damage the brake disc or drum itself, which will significantly increase the cost of repair.
⚠️ Note: If you notice a metal grinding during braking, this means that the friction material has completely worn off and the metal of the pad rubs against the metal of the disc or drum. Operation in this mode is strictly prohibited and will lead to expensive repairs.
Selection of quality spare parts and brands
The spare parts market offers a huge range brake pads for Škoda Octavia A5Which often makes it difficult to choose. Original from Skoda (production ATE, TRW or Textar) ensures perfect matching to the vehicle parameters, but is quite expensive. Alternative can serve as quality analogues that are not inferior in characteristics, but have a more affordable price.
Among the popular manufacturers it is worth highlighting Textar, TRW, ATE and Zimmermann. These brands often supply products to the conveyors of automakers, so their products are distinguished by high quality friction mixtures and stability in various temperature regimes. Cheap Chinese counterparts often have an unstable composition, which can lead to overheating and loss of braking efficiency.
When choosing, it is also important to consider the type of coating and the presence of wear indicators. Some pads have a metal coating on the back to reduce vibrations, while others are equipped with an electronic wear sensor. For cars with electronic hand brakes, it is mandatory to use pads with a compatible sensor, otherwise the system may give an error.

- ATE/TRW
- Textar
- Budget option (Brembo/Remsa)
Necessary tools and preparation for work
Before starting work on replacing the rear pads, it is necessary to prepare the appropriate tool and workplace. For disc brakes, you will need a jack, stands, a set of keys and heads, as well as a special squeeze rod or key to compress the piston. In the case of drum brakes, a removable drum and a set of screwdrivers will be required.
Pay special attention to cleaning the seats. Dirt and rust can prevent the proper installation of new parts and lead to distortion. Use a metal brush and aerosol brake cleaner to remove old lubricant and wear products. The presence of high-quality high-temperature lubricant for guides and contact platforms is also mandatory.
For cars with electronic parking brake control (EPB), a diagnostic scanner or a special entry mode to the service position will be required. Without reversing the piston to the starting position, installing new, thicker pads will be impossible. Attempting to compress the piston mechanically without unlocking the electric motor can lead to breakage of the caliper.
⚠️ Warning: Never attempt to compress an electronically powered caliper piston with a conventional tool without first shutting down the electric motor through the diagnostic interface. This is guaranteed to break the servo mechanism.
☑️ Preparing to replace pads
Step-by-step instructions for replacing the rear brake pads
The replacement process depends on the type of brake system. Let's start with the disc brakes. Remove the wheel and unscrew the lower caliper guide bolt. The upper bolt can not be twisted completely, but it is better to remove the caliper completely so as not to damage the brake hose. Take out the old pads and clean the bracket of dirt.
To install new pads, it is necessary to press the piston into the caliper body. If you have a mechanical hand brake, use a rod. If you have an electronic system, connect the diagnostic scanner and select the Service Position function in the menu. Brake system → Electronic parking brake. The piston will automatically go in.
Install new pads in the brace, making sure they move freely in the guides. Apply special lubrication on the back of the pads and on the guiding fingers. Collect the caliper in reverse order, tighten the bolts with the recommended moment. After installing both wheels, pump the brake system if you opened the circuit.
For drum brakes, the process is more complicated. Remove the drum, which can be fixed with a screw or simply put on the hub. Disconnect the handbrake cable, then dismantle the springs and spacer bar. Clean the internal surfaces and check the condition of the working cylinder for leakage. Install new pads, observing the sequence of attachment of springs.
Nuances of drum pad installation
When installing drum pads, it is important to adjust the spacer bar correctly. If it is too long, the drum will not fit, if it is too short, the brakes will not work. Use the adjustment wheel for pre-setting.

Common mistakes and expert advice
When replacing the rear pads, errors are often made that reduce the effectiveness of braking or lead to rapid wear of new parts. One of the most common problems is ignoring cleaning the calipers guides. If the guides are sour, the caliper will not return to its original position, and the pads will constantly rub against the disk.
Another mistake is to use conventional lithium lubricant instead of specialized high-temperature lubricant. Normal lubrication when heated leaks out or freezes, which leads to jamming. It is also important not to confuse the inner and outer pads if they are of different shapes or lengths.
For owners Octavia A5 With disc brakes on the rear axle, it is critically important to properly calibrate the electronic hand brake after replacement. If this is not done, the system may not press the pads to the end or, conversely, overheat. Use a dealer scanner or a quality analogue with EPB support.
⚠️ Warning: After replacing the pads, be sure to press the brake pedal on the standing car several times so that the pistons fall into place. Otherwise, at the first sharp braking, the pedal can fall to the floor, which will lead to an accident.
Before starting work, be sure to take a picture of the location of springs and spacer bars on the drum brakes. This will save you from assembly errors if you forget the order of installation of parts.
Quality replacement of the rear pads is impossible without thorough cleaning of the guides and the use of specialized lubricant, resistant to high temperatures.

Regular replacement of the rear brake pads with Škoda Octavia A5 This is a guarantee of your safety and the safety of other components of the brake system. Despite the apparent simplicity of the process, especially in drum brakes, certain skills and tools are required. Ignoring the manufacturer’s recommendations can lead to serious malfunctions.
The choice of quality spare parts and compliance with the installation technology will ensure a long and trouble-free operation of the car. Remember that the braking system does not forgive mistakes, and saving on parts or work often translates into even greater costs in the future. Trust complex procedures, such as working with electronic handbrake, to professionals or use appropriate equipment.
How often should I change the rear brake pads to the ŠKODA Octavia A5?
The replacement interval depends on the driving style and operating conditions. On average, the rear drum pads serve from 80 to 120 thousand kilometers, and the disc pads - from 40 to 60 thousand kilometers. However, it is recommended to check their thickness at each planned maintenance.
Can you replace only the rear brake pads without replacing the discs or drums?
Yes, if the surface of the brake disc or drum does not have deep scratches, furrows and is not worn below the minimum permissible thickness. Before installing new pads, be sure to measure the thickness and diameter of the brake element with a rod.
What should I do if I hear a squeaking sound after replacing the pads?
Screaming can be caused by insufficient lubrication of contact areas, getting dirt between the shoe and the caliper, or using poor-quality spare parts. Try to remove the pads, clean the contact places and apply a special lubricant. If the creak hasn’t gone away, there may be a problem with the disc’s geometry or the quality of the friction material.
Do I need a scanner to replace the pads on the electronic handbrake version?
Yes, for cars with electronic parking brake (EPB), a diagnostic scanner is needed to put the caliper into service mode. Without this, mechanical compression of the piston is impossible without breakage of the electric motor. There are special adapters, but the software method is more reliable.
