Remake of the caliper for the ŠKODA Octavia A5: a complete guide to choosing and replacing

Brake system Škoda Octavia A5 (body 1Z32004-2013 is one of the key security nodes where the caliper plays a critical role. Over time, its components wear out: cuffs flow, guides wedge, and pistons are covered with corrosion. Caliper repair kit It allows to restore the performance of the brakes without a complete replacement of the unit, saving up to 70% of the cost of a new caliper. But how to choose a quality set, not run into a fake and correctly perform a replacement? In this article - analysis of articles, step-by-step instructions and Unique nuances of repair calipers Octavia A5, which you will not find in standard manuals.

Model feature Octavia A5 — use of calipers TRW (original) and their counterparts from ATE, Brembo or Febi. At the same time, the remakes for the front and rear calipers differ not only in articles, but also in the design of seals. For example, in the back calipers often there is a problem with piston-turn When assembled back, it requires a special tool. Next, we will analyze everything in steps, from diagnosis to the final pumping of the brakes.

Signs of malfunction of the caliper Octavia A5: when you need a remake

The first symptoms of wear of the caliper components appear long before the complete failure of the brakes. Their disregard leads to uneven wear of the pads, overheating of the discs and even jamming of the wheel. Pay attention to the following signals:

• 🔴 Brake fluid leaks on the inside of the wheel or caliper - a sign of destruction of the piston cuff.
• 🔊 Creaking or knocking when braking, especially at low speeds, indicates wear of guides or springs.
• 🚗 The car pulls to the side when pressing the brake pedal - uneven work of calipers is possible.
• 🔥 Brake disc overheating (Determined by touch after the trip) - the caliper does not completely remove the pads.

On Octavia A5 with engines 1.6 MPI, 1.8 TSI and 2.0 TDI most often suffer front-calipers It's because of the greater load. Rear calipers (if disc-based) usually last longer, but their remixes are harder to find - many manufacturers only offer front-axle kits. For accurate diagnosis, remove the wheel and visually examine the caliper:

⚠️ Attention: If it's on a caliper pistons Octavia A5 You can see deep scratches or corrosion, the remix will not help - you will need to replace the entire caliper. Cuffs will not be able to fit tightly to the damaged surface.

Articula of caliper remixes for the Škoda Octavia A5

Selection of the remix depends on the year of release, the type of engine and the manufacturer of the caliper. Original sets from Skoda supplies TRWHowever, their articles are often duplicated with analogues. Below is a table with the tested versions for the front and rear axles:

Manufacturer	Article	Applicability	Kit contents	Notes
TRW (original)	PFD250	Front caliper (all engines)	Piston cuff, anther, guides	Suitable for calipers LUCAS/TRW piston-wise
ATE	03.9902-3709.2	Front caliper (1.6/1.8/2.0)	Cuff, anther, lubricant.	There is a special lubricant in the kit. ATE Plastilube
Febi	23500	Front caliper (until 2008)	Cuff, anther, lock ring	Not suitable for calipers with electronic parking brake
Brembo	P 85 001	Rear caliper (disc brakes)	Cuff, anther, spring.	Requires additional purchase of guides Brembo P 68 001

For accurate selection, use the VIN of the car or data from the caliper nameplate. Nana Octavia A5 After 2010, the release could be installed calipers with a modified piston design (for example, with a groove under the locking ring). In this case, the remake TRW PFD250 It's not good. PFD251.

When purchasing, pay attention to:

• 📦 Packaging: original sets TRW/ATE have a hologram and serial number.
• 🔍 Cuff material: Quality products are made from EPDM rubber (brake fluid resistant).
• 🛠️ Availability of lubrication: in cheap sets it is often not, and use the usual Litol-24 you can't!

Tools and materials for replacing the remake

A specialized tool will be needed for self-replacement. Without it, the risk of damaging cuffs or piston increases significantly. Here's the full list:

• 🔧 Socket set and ratchet wrench (dimensions 13 mm, 15 mm, 17 mm).
• 🛠️ Caliper piston remover (for example, Hazet 4972-1 for Octavia A5).
• 🧴 Caliper Lubricant: ATE Plastilube, TRW PFG110 or Slipkote 220-R DBC.
• 🔨 Hammer and wooden spacer (for gently knocking out the piston).
• 🧲 Magnetic tray (so as not to lose the retaining rings).
• 🚰 Brake fluid DOT 4 (at least 0.5 litres for pumping).

Pay special attention to lubrication. Nana Octavia A5 cannot be used:

• ❌ Litol-24, Solid oil - destroy rubber seals.
• ❌ WD-40 - washes out the factory lubricant, but does not replace it.
• ❌ Silicone lubricants - can not withstand high temperatures.

Also prepare syringe (for the removal of old brake fluid) and lint-free rags (The fibres can get into the hydraulic system.) If the caliper is heavily contaminated, it will be necessary. brake cleaner (for example, Liqui Moly Bremsen-Reiniger).

Step-by-step instructions for replacing the caliper remplekt

The replacement process takes 2-3 hours per caliper (excluding pumping). The main rule is don't rush and follow the sequence. Let’s start with the front caliper (the most common case for the Octavia A5):

Step 1. Dismantling the caliper

Unscrew the two bolts securing the caliper to the bracket (usually 15 mm). Disconnect the brake hose, pre-substituting the liquid tank. Be careful - the liquid is aggressive for paint coating! Remove the caliper and hang it on the wire so as not to load the hose.

Step 2. Disassembling the caliper

Remove brake pads and spring-loaded locks. Carefully remove the anther of the piston (it is usually glued to the body). Using a camera or compressed air (maximum 2 atm!), push the piston out. Do not use metal objects - they scratch the cylinder mirror.

Step 3. Replacement of cuffs and assembly

Remove the old cuff from the piston groove and clear the seat. New cuff is being installed without distortions - its edge should evenly enter the groove. Before installing the piston, apply a thin layer of lubricant to its surface and the inside of the anther. Collect the caliper in reverse sequence.

Step 4. Installation and pumping

Set the caliper in place, plug in the brake hose and tighten the bolts with the moment. 30 Nm. Pump the brake system, starting from the farthest wheel from the main cylinder (on the main cylinder). Octavia A5 Order: rear right → rear left → front right → front left.

⚠️ Attention: On Octavia A5 with the system ESP after brakes are applied brake pedal sensor adaptation via a diagnostic scanner (for example, VCDS). Without this, an error may appear ESP on the dashboard.

What to do if the piston does not come out of the caliper?

If the piston is stuck, try the following:

1. Pressure the air through the brake hose hole (no more than 2 atm!).

2. Carefully tap the wooden frame on the edge of the piston.

3. Pour into the caliper cavity WD-40 and leave for 10-15 minutes.

4. If the piston is damaged (deep scratches, corrosion), the caliper must be replaced.

Typical mistakes when replacing a repair kit and how to avoid them

Even experienced craftsmen make mistakes that lead to re-repair. Here are the most common examples of them. Octavia A5:

• 🔧 Distortion of cuffs when installed - leads to fluid dwindles in 1-2 thousand. km. Solution: Use a special cone tool for pressing.
• 🧴 Incorrect lubrication The guides cause the caliper to jam. Solution:lubricate finger-onlyNot the rubber anther.
• 🔨 Damage to the piston anther When removed, it leads to dirt entering the cylinder. Solution: to put an anther with a plastic tool, not a screwdriver.
• 🚗 Incomplete pumping Residues of air in the system reduce the effectiveness of braking. Solution: pump until the liquid goes without bubbles.

Another common problem is incompatibility of repair kits. For example, a caliper kit. ATE won't fit TRWEven if the cuffs are visually similar. The difference may be in the diameter of the groove under the locking ring or rubber material. Always check the items with the manufacturer's catalog.

On Octavia A5 with rear drum brakes (version before 2008) the caliper remake is not needed - a different design is used there. But if your car is equipped with rear disc brakes, pay attention to the caliper: it often breaks down when disassembled and requires replacement (article) 1K0 615 407).

Cost of work and savings: comparison with the replacement of the caliper

Repairing the caliper with a remix is much cheaper than a full replacement. Consider the prices on the example of the front caliper Octavia A5 (as of 2026):

Service/Part	Cost (RUB)	Notes
Repair kit TRW PFD250	1 200–1 800	Price depends on the region and the seller
New caliphor TRW (original)	8 000–12 000	Includes fasteners and guides
Work on the replacement of the remplekt (STO)	2 500–4 000	Does not include bleeding the brakes
Work on the replacement of the caliper (STO)	3 500–5 000	Includes pumping and adjustment

As you can see from the table, repairs with remplekt save up to 7,000 rubles on the same caliper. However, please note that:

• 💰 Savings justifiedIf the caliper body is not damaged and has no signs of severe corrosion.
• ⏳ Repairs take longerIt's better than replacing the calipers.
• 🔧 Experience is required It is easy to make a mistake at the first attempt (see para. previous section).

If you decide to repair the caliper yourself, assess its condition in advance. For example, on Octavia A5 after 150,000. mileage guide-carving In this case, the repair is meaningless, you need a new caliper.

Recommendations for maintenance of calipers after repair

To ensure that the remake lasts as long as possible, follow these tips:

• 📅 Check the calipers. every 30,000. km or when replacing the pads.
• 🧴 Lubricate the guides every 15,000. km (use only specialized lubricants).
• 🚿 Wash the calipers. When replacing the pads - dirt accelerates the wear of the cuff.
• 🔧 Check the brake fluid level - low levels lead to air suction.

On Octavia A5 with the system ESP after any interference with the braking system (including replacement of the remplekt) it is recommended to perform brake-sensor. This can be done with diagnostic equipment (e.g., VCDS in the block 03-ABS, channel G201). Without calibration, false positives are possible. ESP Or increased pedal travel.

Also note brake hoses. On cars over 10 years old, they often crack from the inside, which leads to a “cotton” brake pedal. A sign of hose wear. swelling. In this case, the hoses require replacement (articles: front). 1K0 611 721, rear 1K0 611 722).

💡

After replacing the remake, the first 200 km avoid sharp braking - new cuffs need time to burn.

FAQ: Frequent questions about Octavia A5 caliper remakes

Can I use a remake from the VW Golf 5 on the Octavia A5?

Yes, Octavia A5 and VW Golf 5 (platform PQ35) have the same calipers. For example, remake TRW PFD250 It is suitable for both models. Check the VIN of the car on some versions. Golf 5 calipers Brembo with a different attachment.

How often should I change the caliphate remake?

Recommended interval - Every 100,000 to 150,000. km or at the following signs:

• Brake fluid drips.
• The piston jamming (the wheel is heated without braking).
• Uneven wear of the pads (one side wears off faster).

On Octavia A5 With intensive operation (taxi, courier delivery), the resource of the remake is reduced to 80 thousand. km.

What are the different sets for calipers with electronic parking brake (EPB)?

On Octavia A5 with EPB (electronic handbrake) is installed calipers with electric-engine. Their remixes (e.g., TRW PFD251) include additional drive seals. Important: after replacement of the cuff is required EPB calibration through the diagnostic scanner, otherwise the handbrake won't hold.

Can you restore the caliper without a remix, only with lubrication?

No, it's a temporary solution. Lubrication guides will eliminate the creak, but will not solve problems with:

• The stained cuffs (will lead to leaks).
• Corrodated piston (can jam at a critical moment).
• Destroyed anthers (the dirt will get into the cylinder).

On Octavia A5 Such "repair" often ends with the replacement of the caliper after 5-10 thousand. km.

What brake fluid to fill after replacing the remplekt?

For Octavia A5 liquid recommended DOT 4 with a boiling point not lower 230°C. Suitable options:

• ATE SL.6 (article 03.9901-0001.2).
• Liqui Moly DOT 4 (article 7654).
• Castrol React DOT 4 Low Temp.

ImportantDo not mix liquids from different manufacturers - this reduces the boiling point.
