Car owners when replacing brake pads often encounter thin metal pads included in the kit. Many do not even pay attention to them, considering them as an extra spare part. The name of this part is anti-creak brake pad plates. Do they really remove the squeak? And if not, what are they for?
Description and purpose
Anti-creak plates are also called balancing plates. Their main role is to redistribute the force from the brake piston over the entire surface of the pad. In case of ingress of dust or dirt in the absence of such plates, a slight distortion of the block is possible. This almost always causes an unpleasant sound from the brakes. That is why the plates are called anti-creak.
Outwardly they consist of two parts and are made of thin metal (tin). The plates follow the contours of the brakepads, and they are located on its non-working side, closer to the piston. The part that comes into direct contact with the brake piston is in the form of a solid plate. The other, which is adjacent to the block, is corrugated. This is just necessary to be able to evenly distribute the force in the presence of contamination.
The appearance of anti-squeal plates is often misleading. Subtle and frivolous, they are often not taken into account and not established. This attitude is also facilitated by the fact that discs are not included in non-original sets. And if the car owner has a car with pads already replaced with non-original pads, then even more so.
In fact, the pads may not creak without such plates. This is due to the good operating conditions of the car and timely maintenance. That is, with proper technical care, when all brake mechanisms are regularly carefully sorted out and lubricated.
Rear brake pad anti-squeal plates are original only for cars with rear disc brakes.
Squeaker or anti-creak plates?
Brake pad replacement kits for disc brakes sometimes have so-called squeakers. They should not be confused. The anti-creak plates of the brake pads repeat the shape of the lining, and the creaker is a small, intricately curved tin. It is usually installed perpendicular to the long axis of the block by riveting or snapping.
The purpose of such a record is completely different - on the contrary, it creaks when the block is close to abrasion, hence its name. In fact, this is a cheap version of the brake pad wear sensor. It is made of soft metal and does not tolerate distortion and deformation for brake discs.
"Squeakers" in brake replacement kits are much more common. They are also produced by companies that supply non-original products.
Original brake pad replacement kits always come with a small sachet of grease. Often they are simply lubricated with guides. It turns out that this special lubricant is for the anti-creak plates to work. Indeed, without this, they will behave just like a pair of tin cans and cause a terrible noise. It is thanks to the lubricant that is applied to the corrugated plate that the remarkable effect of uniform, silent pressing of the pad occurs.
What to do if there is no lubrication, how to lubricate the anti-creak plates of brake pads? This can happen when replacing a non-original set, when the records remain unworn. Lubricant for adjusting plates has special properties. Firstly, it must be high-temperature, since during intensive work with brakes, one disc can heat up over 500 ° C. Secondly, the synthetic base and the absence of impact on rubber products - guide anthers are important. Among the well-known companies producing lubricants, it is widely knownLiqui Moly.
Most importantly, do not use lithium and graphite lubricants, which are not suitable for temperature and burn out quickly. In addition, they cause deformation of the rubber anthers. Copper grease is not suitable either. Burning out, it also leads to corrosion.
Maybe do it yourself?
It happens that it is not possible to order an original set of brake pads. At the same time, the native plates from the creak also fell into disrepair. In this case, there are only three options for getting out of the situation:
- Leave everything as it is and do not drive the car, so as not to wear out the brake discs.
- Change the kit without the plates and just keep a close eye on the condition of the brakes.
- Be smart and make your own brake pads.
What might be required for this? Yes, just the same thickness of a sheet of tin. Attaching an old anti-creak plate to it, carefully trace it along the contour with a pencil. Then, using metal scissors, we cut out the plate as accurately as possible. After that, aligning the old and new parts and pressing them together with clamps or a vice, we bring the file to a complete match.
Both anti-squeak records are made in the same way. A corrugated inner plate will require more time and patience, but it will also give up before perseverance and work. It remains only to choose the right lubricant - and that's it. Now the pad is skewed or its central deformation in the place where it pressespiston, don't be afraid.
How hard is it to find anti-squeal pads?
How rare are kits that have anti-squeal brake pads? Where do questions about making plates with your own hands come from? In fact, there is no excitement. The plates are always included in the original brake pad replacement kits for disc brakes. Almost all Japanese foreign cars are supplied with such kits. At the same time, the price of sets in the original packaging significantly exceeds any analogue. It is sometimes more difficult to find separate records against the squeak.
Again, as far as Japanese cars are concerned, the original catalogs have all the information. It is easy to find separately and the number of the described part. Toyota brake pads, for example, are sold and ordered separately.
Among non-original companies, TRW stands out well. The range of pad kits of this company includes complete copies of the originals, in which anti-squeal plates are necessarily present.
Nissan anti-creak plates
Japanese cars are a high-tech product. On many cars of Japanese origin, anti-creak plates have long been installed. In order not to be unfounded, consider as an example the Nissan Teana, 2006 release.
By entering all the necessary data, and this is the Vin-number or body number for a right-hand drive car, we get full access to the car's spare parts.
After going through the "brake system" branch, we find the front pads without much difficulty. There is also a catalog number of the pads themselves - AY040NS106, by driving it into any online store, we will get the price and delivery time of the spare part, as well as the price and delivery time of non-originals.
Nissan Teana brake pads also have their own separate catalog number - 41080AU025. This kit includes all plates for changing pads: two anti-squeal and one squeaker for each wheel.
Anti-squeal brake pads are still a very controversial topic in automotive forums. Among the arguments for and against the main criteria are observations after the installation of plates and without them. So, some members of the forum notice the lack of changes. That is, the pads both creaked and continue to creak. And opponents argue that in this case there are installation inaccuracies and defects not related to the plates.
Some netizens note the possibility of using non-original brake pads without anti-squeak plates. At the same time, there is no noise during operation. Based on the foregoing, only the manufacturer can recommend something, and you will have to solve the issue with the installation yourself.
Considering the use of plates against creaking, you understand more and more that there is nofinal decisions. Despite the specific recommendations of automakers to install original spare parts, many users have their own, different from the official, opinion. Therefore, the kit: brake pads, anti-squeak plates and lubricant is an excellent option that allows you to use all the achievements of technical thought and drive without squeaking. And for those who don't want to use plates, there are always other options.

The brake system is one of the most important components of any car. Its main elements are the disc and pads. Braking is based on the force of friction. The pads are in contact with the disc, resulting in resistance to torque. The car starts to slow down. However, over time, the friction material wears out and the pad needs to be replaced
The brake system is responsible for the safe braking of the car. The efficiency of the process depends on its serviceability. The number of mechanisms in the brakes is quite large, and all of them should work like clockwork, because the failure of one will entail at least unpleasant consequences. Let's talk about what should be the minimum thickness of the brake pads, as well as how to check for wear
