Traffic safety is directly dependent on the performance of the brake system, and the rear brakes play a critical role in this process. For owners. Skoda Octavia A5 timely replacement of consumables is not just a recommendation, but a necessity, since the wear of the pads affects the overall balance of braking.
Many car owners face a dilemma: choose original parts or turn to proven analogues. In the case of the platform PQ35, on which it is based Octavia A5The choice is huge, but not all solutions guarantee long service without creaking and loss of efficiency.
Correct selection rear brake pads Requires consideration of the type of brake system (drum or disc brake), the year of production of the car and driving style. Ignoring these nuances can lead to premature wear of brake discs or even system failure in an emergency.
Types of brake systems on the Skoda Octavia A5 and their features
The first and most important step before buying parts is to determine the type of brake mechanism behind. Skoda Octavia A5 It was offered with two options for rear suspension, which directly dictates the choice of pads.
On cars with a small and medium power engine (for example, 1.6 MPI or 1.4 TSI earlier versions) the drum brake system was installed. In this case, it is about replacing the brake linings inside the drum, not about the classic disc pads. This system is cheaper to manufacture, but requires more careful maintenance when replaced.
On more powerful versions (1.8 TSI, 2.0 TDI, RS) and in some configurations with ABS, the rear axle was equipped with disc brakes. It is for them that the need for replacement is characteristic. brake-pad with an electronic or mechanical hand brake lock. An error in determining the type will lead to the fact that the purchased parts simply do not fit the fastener and size.
The Disk System Feature on Octavia A5 It is the use of a piston with thread. When installing new pads, the piston is not just pressed in, but screwed clockwise, which requires a special tool or universal mandrel.
Signs of wear and diagnostics of brake condition
It is possible to understand that it is time to change consumables by a number of characteristic symptoms that cannot be ignored. The most obvious signal is a characteristic squeak or screech when pressing the brake pedal, which occurs due to the work of the wear indicator.
If you notice that the car pulls to the side when braking, this may indicate uneven wear of the pads or jamming of the calipers guides. In the case of drum brakes, a sign of wear is often a decrease in the effectiveness of the hand brake when the lever has to be lifted to the point.
Visual examination is the most reliable method of diagnosis. Removing the wheel, you can estimate the thickness of the friction lining. If it is less than 2-3 mm, replacing brake pads It should be done immediately, without delaying until later.
Also worth paying attention to the beating of the steering wheel or vibration of the pedal, although this often indicates deformation of the discs, but often goes in combination with worn pads.
Review of manufacturers and selection of quality spare parts
The auto parts market offers hundreds of options, from budget Chinese kits to premium German brands. For Skoda Octavia A5 It is critical to choose proven manufacturers, as cheap counterparts often dust, creak and quickly erase.
The gold standard is considered to be brands-suppliers on the conveyor: TRW, Ate, Textar, Remsa and Ferodo. These companies produce pads identical to the original, but often cheaper due to the lack of markup for the dealer's logo.
If the budget is limited, it is worth considering the average price segment of brands. Brembo, Febi or SWAG. They provide a decent value for money, although the composition of the friction mixture may differ from the original, which sometimes affects the noise level.
Avoid unknown brands with suspiciously low prices. Saving on brakes is a risk that can cost a life. The original rear pads for disc brakes usually start with the prefix 1K0 or 5Q0, depending on the year of release.

Tools and preparation for replacement
Before starting work, you need to prepare all the necessary equipment to make the process go quickly and safely. To replace the pads with Octavia A5 You will need a standard set of wrenches, jack and stops for wheels.
The key tool is a device for twisting the caliper piston. Conventional pliers will not help here, since the piston has a special thread. You can use a universal set for brakes or an adapter for a particular model.
Also, it is necessary to have a balloon head, a dynamometer key (for tightening the wheel) and a brake cleaner. Donβt forget about copper lubrication for guides and seats to avoid corrosion and jamming.
- π§ A set of socket heads (usually 13, 15, 17 mm).
- π οΈ The caliper piston fitting.
- π§Ό Brake Cleaner (Brake Cleaner) in an aerosol.
- 𧴠Heat-resistant lubricant for calipers guides.
Work is better carried out on a flat solid surface. Lift the car with a jack, install it on the safety stand and remove the wheel. Free access to the caliper by unscrewing the fasteners.
βοΈ Preparing to replace pads
Step-by-step instructions for replacing pads
We start the process by unscrewing the guide calipers. Usually it is two bolts at the bottom and top that hold the brace. Carefully remove the brace, trying not to damage the brake hose. You can hang a brace on the wire for this.
Remove the old pads. Pay attention to how they stood and clear the seats of dirt and rust. If there are metal brackets-fixers, it is better to replace them with new ones included in the kit.
Now the most important moment is the return of the piston to its original position. Insert the mandrel and rotate the piston clockwise, while pressing it. Do this slowly so as not to damage the cuff. Watch the level of brake fluid in the tank, as when the piston is pressed, it will rise.
Install new pads in place, making sure they are free to walk in brace. Return the brace to place and tighten the guide bolts with the required force. Be sure to pump the brakes after assembly if you have opened the system or if the pedal has become soft.
- π Clean the surfaces of the discs of dust and oil before installation.
- π© Lubricate the guide calipers with a special high-temperature lubricant.
- π§ Tighten the bolts of the guides with a dynamometer key (usually 25-30 Nm).
- π§ͺ Check the level of brake fluid in the tank before starting work.
After installing all the wheels, you need to press the brake pedal several times to the end so that the pistons take the correct position relative to the new pads. Only then can the car be moved from the spot.
What to do if the piston does not screw in?
If the piston fails, check if it is blocked due to skewing. Try to shake it slightly when you spin. In rare cases, the piston may be jammed with corrosion, then it will need to be replaced or the caliper restored.
The nuances of servicing drum brakes
If you have a version with drum brakes, the replacement process has its own differences. There is no caliper, and instead of it - a drum, which must be removed, having previously unscrewed the screw on the hub.
After removal of the drum, access to brake pads and hand brake mechanism is opened. Pay attention to the condition of the springs and the proppant mechanism. Old springs often lose elasticity, which leads to poor disinhibition.
When installing new drum pads, it is important to properly adjust the handbrake cable. After replacement, be sure to check the parking brake, making sure it keeps the car on an gradient.
Unlike a disk system, drum pads wear out more slowly, but they are more sensitive to water and dirt. Regular cleaning of the mechanism will prolong their service life.
β οΈ Warning: When working with drum brakes, be extremely careful with dust from asbestos linings. Use a respirator and do not blow away the dust with compressed air, it is better to moisten it with water or a cleaner.
Proper tightening of guides and the use of high-quality lubrication is the key to the absence of creaks and jamming of the caliper.

Frequently asked questions (FAQ)
How often should I change the rear brake pads on the Skoda Octavia A5?
The service life depends on the driving style and operating conditions. On average, the rear disc pads go from 40 to 60 thousand kilometers, and drum pads can last up to 80-100 thousand kilometers. Regular diagnosis at each point is mandatory.
Is it possible to change only one pad on an axle?
No, it's categorically not recommended. Change the pads in pairs on one axis (left and right side) to ensure uniform braking. Otherwise, the car will be taken away during a sharp braking.
What to do if a squeak appears after replacement?
Scream can be caused by several reasons: lack of lubrication on the metal plates of the pads, poor-quality material of the friction lining or the need for laundry. Try lubricating the back side of the pads with a special lubricant and make several smooth braking.
Do I need to change the brake disc along with the pads?
It depends on the state of the disk. If it has deep furrows, cracks or is worn below the minimum thickness (as indicated on the disc itself), it must be replaced. Otherwise, the new shoes will quickly become useless.
Can a universal tool be used to screw a piston?
Yes, most universal brake kits are suitable for calipers Octavia A5. The main thing is to choose the right adapter and rotate the piston strictly clockwise, without putting excessive effort.
