The braking system is a critical safety element of any vehicle, and Skoda Octavia Tour This is no exception. Owners of this popular sedan and hatchback are often faced with the need for scheduled maintenance, where replacing the brake pads occupies one of the central places. Ignoring system signals or delaying a service visit can lead to costly repairs to calipers and discs.
Replacement procedure brake pads on family cars A5 (Tour) has its own characteristics related to the design of the rear calipers and the presence of electronic wear sensors. Unlike the front wheels, where the mechanism is simpler, the rear axle requires the use of a special tool to press the piston. Understanding these nuances will allow you to save time and money by doing the work yourself or supervising the actions of specialists at a service station.
In this article, we will analyze in detail the timing of replacement, criteria for selecting quality spare parts, as well as a step-by-step algorithm of actions. We will pay special attention to the differences between the front and rear units, since structural differences require a different approach to maintenance. Important: the rear wheels of the Skoda Octavia Tour often use an electronic wear sensor, which requires replacement along with a set of pads, otherwise the error will remain on constantly.
Signs of wear and diagnostics of the brake system
Determine the need for replacement brake pads can be done both visually and by characteristic signs during operation. The most obvious signal is a squeaking or metallic grinding sound when you press the brake pedal. This sound occurs because the wear layer has thinned and the metal base of the pad begins to come into contact with the brake disc. It is absolutely impossible to ignore such a signal, as this leads to destruction of the disk.
The second important indicator is the behavior of the car when braking. If you feel vibration in your steering wheel or pedals, this could indicate uneven wear or warped discs caused by overheating. It is also worth paying attention to the length of the braking distance: if it has increased noticeably, the brake fluid may have lost its properties or the friction linings have lost their effectiveness.
For an accurate diagnosis, it is necessary to remove the wheels and inspect the condition of the parts. Visual inspection allows you to assess the thickness of the friction layer. If it is less than 2-3 mm, replacement becomes mandatory. In addition, check for oil stains on the pads, as liquid ingress dramatically reduces the coefficient of friction.
- 🔊 A squeaking or squeaking sound when you lightly press the brake pedal.
- 🛑 Metallic grinding noise requiring immediate stop.
- 🚗 The car pulls to the side during emergency braking.
- 💡 The wear indicator on the dashboard lights up.
⚠️ Attention: Do not attempt to lubricate squeaking pads! This will only temporarily hide the problem, but will lead to complete brake failure when heated.
Often owners Octavia Tour notice that the wear indicator lights up before actual wear has reached a critical point. This is done for safety so that the driver has time to schedule repairs. However, the sensor may fail even earlier, showing a false alarm, so always check the instrument readings with the visual condition of the parts.
Selection of quality spare parts: original or analogues
The auto parts market offers a huge selection of solutions for the braking system. Skoda Octavia Tour. The original is guaranteed quality that meets factory specifications, but is often overpriced. Original parts manufacturers (OEM) for Skoda are usually ATE, TRW, Textar or Brembo. When you buy a box with the VAG logo, you often get the same product as in the box from those brands, just paying a premium for the car brand.
Analogues offer a more affordable price with decent quality. It is important to choose trusted manufacturers, such as Galfer, Jurid, Pagid or Ferodo. Cheap Chinese or little-known brands may contain asbestos or low-quality binding materials, which will lead to rapid wear, overheating and even boiling of the brake fluid. Saving on brakes is a direct risk to life.
When choosing, pay attention to the equipment. Original kits often already have a wear indicator and mounting brackets. In analogues, the sensor may be sold separately, and brackets are sometimes missing. The absence of spring clamps can cause the pads to rattle when moving, creating an unpleasant noise.
- 🏆 ATE is a premium brand, excellent performance, but high price.
- 🛠️ TRW is a reliable standard and is often installed on the assembly line.
- 💰 The Pagid is great value for money for everyday driving.
- 🌱 Textar - soft pads, less dusty, but wear out faster.
- Original VAG
- ATE/TRW
- Budget analogues
- It doesn't matter, the main thing is the price
If you choose an analogue, be sure to check the catalog numbers. For front pads Octavia Tour numbers starting with 1K0 are often used, and for the rear ones - 1K0 or 5Q0 depending on the type of drive and motor. An incorrectly selected kit may simply not fit into the caliper or have a different friction area.
⚠️ Attention: Never change pads on only one axle! Always change the set (left and right) at the same time to avoid distortion of the braking forces.
Tools and workplace preparation
Before starting work, you need to prepare the necessary tools. To replace the front pads you will need a standard set of wrenches, but for the rear calipers Skoda Octavia Tour A special tool for turning the piston is critical. Trying to press the piston with a clamp, as on the front wheels, will lead to breakdown of the mechanism and expensive repairs.
You will also need a jack, car stands (goats) and a wheel wrench. Do not work under a machine supported only by a jack - this is deadly. Make sure that the car is on a level surface and is securely locked with the handbrake (if the front pads are being changed) or in gear.
- 🔧 A set of socket heads (usually 13, 15, 17 mm).
- 🌀 Special wrench for tightening the rear caliper piston.
- 🛢️ Container for draining brake fluid (if necessary).
- 🧴 Brake cleaning spray and graphite lubricant.
☑️ Preparing to replace pads
Pay special attention to cleaning work surfaces. Dirt and rust on the caliper guides can cause the pads to stick to the rotor, causing persistent braking and overheating. Use a wire brush and brake cleaner to remove any deposits before installing new parts.
⚠️ Attention: Do not press the brake pedal with the wheels removed! This will cause the pistons to come out of the calipers and cause fluid to fall out.
Step-by-step instructions for replacing front pads
Replacing the front pads with Octavia Tour is relatively simple and does not require complex manipulations with the piston. Remove the wheel, unscrew the lower caliper guide bolt (usually 13 or 15 mm) and fold the caliper bracket up. Old pads are easily removed from the bracket. Check the condition of the guide boots and replace them if necessary.
Before installing new pads, it is necessary to recess the caliper piston into the housing. To do this, use a flat pry bar or a special tool, gradually pressing the piston until it stops. Monitor the level of brake fluid in the reservoir under the hood - when the piston sinks, the level will rise, and if it is too high, some of the fluid must be pumped out so that it does not spill out.
Install the new pads, making sure they move freely in the guides. Lubricate the caliper guides with special silicone grease, but under no circumstances allow the grease to come into contact with the friction lining or disc. Return the bracket to its place, tighten the bolt and repeat the procedure on the second wheel.
Before reassembling, wipe the brake disc with cleaner to remove any dust or oil remaining after replacement.
After installing all the parts, it is important to press the brake pedal all the way down several times so that the pistons come out and press against the new pads. Only after this can you lower the car to the ground and check the operation of the brakes while driving. Avoid emergency braking for the first 100-200 kilometers to allow the pads to get used to it.
Features of replacing rear pads and sensors
Rear brake system Skoda Octavia Tour has a design feature: the rear caliper piston is not simply pressed in, but must be screwed in clockwise while being pressed at the same time. This is due to the fact that the rear caliper is often combined with the handbrake mechanism. It is impossible to perform this operation without a special mandrel key.
The process begins by removing the wheel and unscrewing the guide bolts. After removing the bracket, remove the old pads. If you have a wear sensor installed, its wire must be carefully disconnected from the block. A new sensor usually comes complete with new pads, so you need to cut out the old wiring and replace it with a new one, connecting it to a connector in the passenger compartment or under the wheel.
