Regular brake system maintenance is a critical aspect of safe vehicle operation. ล koda Yeti. The wear of the friction linings directly affects stopping efficiency, especially in city traffic or when driving off-road, where the weight of the crossover creates a significant load on the components. Ignoring signs of wear can lead to expensive repairs to calipers and discs, as well as create an emergency situation on the road.

Brake replacement process pads on this model does not require extreme skills, but has a number of technical features characteristic of the VAG platform. Incorrect assembly or use of the wrong tools can damage the caliper guides or piston, requiring replacement of the entire mechanism. In this article we will analyze in detail the sequence of actions, tools and important nuances so that you can complete the job efficiently and safely.

Preparing tools and selecting consumables

Before you get started, you need to make sure you have a full set of tools and quality parts. For ล koda Yeti You will need both standard wrenches and a specific tool for recessing the piston, especially on the rear axle.

You will need: a ratchet with an extension, 13 and 16 mm (for the front caliper) or 7 mm (for the caliper) sockets, a torque wrench, grease for the guides and copper grease for the contact surfaces. Don't forget to prepare a jack and reliable stands for the car.

  • ๐Ÿ”ง Socket set and ratchet
  • ๐Ÿ› ๏ธ Special key for turning the piston (for rear calipers)
  • ๐Ÿงด Caliper Guide Lubricant (High Temperature)
  • ๐Ÿงผ Brake Cleaner

When choosing new pads, it is important to pay attention to the manufacturer. Original spare parts from ล koda usually supplied under the brand TRW, ATE or Textar. Alternative brands such as Brembo or FERODO, also show excellent results, but require careful verification of authenticity.

It is important to check the contents of the new pads: the kit should include new mounting brackets (shields), if provided for by the design, and spring clips. Old metal elements often become deformed and can cause squeaking even with new linings.

Dismantling the wheels and removing the caliper

Raise the car on a jack and be sure to place it on safety stands. Remove the wheel and inspect the brake rotor for deep scratches or uneven wear. If the disc is critically worn, replacing the pads alone will not solve the problem of vibration during braking.

Clean the area around the caliper of dirt and dust using compressed air or a brush to prevent abrasive particles from entering the mechanism during disassembly. Unscrew the two caliper guide bolts. On the front calipers Yeti they are usually located at the bottom and top, and have a 13 mm wrench size.

โš ๏ธ Attention: Do not disconnect the brake hose from the caliper! When removing the caliper, you just need to hang it on a wire or hook so as not to damage the rubber hose from its own weight.

Carefully remove the caliper from the brake rotor and set it aside, hanging it up. The old pads are now visible in the bracket. Remove them, removing the old spring clips if they are stuck. The bracket can be left on the hub or removed completely for more thorough cleaning.

  • ๐Ÿšซ Do not hang the caliper on the brake hose without support.
  • โœ… Use soft wire for hanging
  • ๐Ÿงน Clean any rust from the caliper bracket before installing new parts.

If the bracket is being removed, unscrew the two bolts securing the bracket to the steering knuckle. Clean the seats from corrosion. This is critical for the new pads to move freely and prevent binding.

Front pad replacement process

Before installing new pads, you must push the caliper piston back into the housing. On front calipers this can be done by simply pressing or through a screw if the piston is threaded. Use a clamp or an old piston to press down while monitoring the brake fluid level in the reservoir.

Make sure the piston moves smoothly and does not bind. If it does not respond, there may be excess pressure in the system, and you need to unscrew the brake fluid reservoir cap a little. After pressing the piston, clean it of old grease and apply a new layer of high-temperature grease.

Install new spring clips onto the bracket. They should fit snugly and not wobble. Insert new ones brake pads into the bracket. Pay attention to the location of the noise insulation plates and the wear sensor (if included in the package).

Apply a thin layer of copper grease to the back of the pads and where they contact the piston to eliminate squeaks. Do not apply lubricant to the working surface of the pad! This may result in loss of braking efficiency.

  • Original (TRW/ATE)
  • Premium (Brembo/Ferodo)

Return the caliper to its place, aligning the holes for the guide bolts. Insert new guide bolts and tighten them to the recommended torque. Usually it's about 30 Nm for guide bolts and 100 Nยทm for bracket fastening bolts (check in the manual of your modification).

โš ๏ธ Attention: Be sure to replace the old guide bolts if they show signs of corrosion or damage to the boots. Old bolts can become stuck, causing uneven pad wear.

Features of replacing rear pads

Rear brake system ล koda Yeti often has a mechanical parking brake integrated into the caliper. This means that the piston cannot simply be pressed in, but must be rotated and pressed at the same time. This requires a special tool or a universal puller.

If you have an electronic handbrake, the procedure must begin by switching the calipers to service mode via a diagnostic scanner. Without this, the pistons will not sink and you may damage the mechanism. You cannot manually turn the piston of the electronic handbrake.

  • ๐Ÿ”‘ For manual handbrake: use hex wrench or puller
  • ๐Ÿ“ก For electronic handbrake: diagnostic adapter required (VCDS/ODIS)
  • ๐Ÿ›‘ Do not try to press the piston without turning it - it will break

After the piston is recessed, the installation of new pads occurs in the same way as the front axle. Install new spring retainers and the pads themselves. Check that the wear sensor is in place and that the wire is not pinched.

Return the caliper to the bracket and tighten the guide bolts. Don't forget to check the condition of the guide boots. If they are torn, the lubricant will leak and the caliper will seize. In such cases, it is recommended to replace the anthers with new ones.

Done: 0 / 5

After assembling all the wheels, you need to bleed the system or simply press the brake pedal all the way down several times so that the pistons reach their working position and the pads press against the discs. The brakes won't work effectively until you do this.

What to do if the piston does not rotate?

Sometimes the piston seizes due to corrosion or lack of lubrication on the threads. Try gently rocking it while applying penetrating lubricant. If this does not help, you may need to replace the piston or the entire caliper assembly.-->

Checking and running in new brakes

After completion of work, be sure to conduct a visual inspection. Make sure all bolts are tight, boots are in place, and there are no brake fluid leaks. Check the fluid level in the tank - it could have dropped due to the pressing of the pistons, and it needs to be brought up to normal.

The first few kilometers after replacement, it is necessary to observe the break-in regime. Avoid sudden braking and stopping completely. The pads need time to rub into the disc and form the correct layer of friction material.

During the break-in process, watch for any extraneous sounds.

squeaks, knocks or vibrations. If you hear a grinding noise, something may have been installed incorrectly or dirt may have entered. In this case, it is better to immediately return to the examination.

Below is a table with recommended tightening torques for the main components of the brake system ล koda Yeti:

Knot Bolt size Tightening torque (Nm) Note
Caliper guides (front) M10 30 Be sure to use new lubricant
Attaching the caliper bracket M12 100 Tighten with a torque wrench
Caliper guides (rear) M10 30 Check the anthers
Attaching the caliper to the knuckle (rear) M14 120 Requires large key lever
Wheel bolts M12 120 Tighten crosswise
โš ๏ธ Attention: It is strictly forbidden to use sealant on the threads of the caliper guide bolts, as this interferes with their mobility and can lead to jamming of the mechanism.

After the first ride, check to see if the calipers are overheating. If one wheel is significantly hotter than the others, it is a sign that the guide bolt is stuck or the piston is not coming out completely. In this case, the work needs to be redone.

Common mistakes and advice from professionals

One of the most common mistakes is using the wrong lubricant. Graphite or copper grease should not come into contact with the working surface of the pad or disc. This reduces the coefficient of friction and can lead to brake failure at a critical moment.

Ignoring the condition of brake discs is also a common mistake. If the disk has an output of more than 2 mm from the nominal thickness, it must be replaced along with the pads. Installing new pads on a worn disc will lead to their rapid destruction.

  • ๐Ÿ” Always check disc thickness before replacing pads
  • ๐Ÿงผ Clean all surfaces from rust and dirt
  • ๐Ÿ›‘ Don't skimp on the quality of guide lubricant

If you are planning to replace only one axle, remember that the brakes work in pairs. Replacing only the front or only the rear pads can lead to an imbalance of braking forces and instability of the vehicle when braking.

Sometimes during assembly there is a problem with the wear sensor. Make sure that the sensor wire is not stretched and has a small margin of length when turning the wheel. If the wire is stretched, it may break when turning the steering wheel, and the sensor will stop working.

Regular replacement of brake fluid every 2 years is a must to maintain the effectiveness of the braking system and prevent corrosion of the pistons from the inside.

FAQ: Frequently asked questions about replacing pads

Below are answers to the most popular questions that owners have. ล koda Yeti when replacing brakes yourself.

Do I need to change the pads on both wheels of the same axle at once?

Yes, this is a mandatory safety requirement. Different pad wear on one axle will lead to uneven braking, which can cause the car to skid during sudden braking.

How do you know when it's time to change the brake pads on your Yeti?

Main signs: the appearance of a metallic squeak or squeak when braking, pedal vibration, increased pedal travel, or a wear indicator on the dashboard (if there is a sensor).

Is it possible to replace the pads without removing the wheel?

Theoretically, it is possible if there is access to the caliper through the holes in the disc, but this is extremely inconvenient and risky. A complete replacement requires removing the wheel to access the guides and check the condition of the disc.

What should I do if my brakes become soft after replacing them?

Most likely there is air left in the system. The brake system needs to be bled. If the problem persists, check that the piston is completely recessed and that the caliper is not damaged.

How long does it take to replace front pads?

For an experienced craftsman, this takes about 30-40 minutes per axis. A beginner will need 1-1.5 hours, as he needs to carefully study the design and check every step.
