Best lubricant for brake cylinders

All systems of the car during its operation should be serviceable. But you need to pay special attention to the brakes. After all, often the life of the driver, passengers, other participants in the movement and pedestrians depends on the state of the brake system of the car. Periodically it needs to be serviced. This is to replace the brake pads, discs, fluid, as well as calipers. For example, lubrication for brake cylinders during their maintenance and replacement is simply necessary. We'll talk about all this.

Lubrication of guide rails

Before you go directly to the cylinder, you need to understand its guides. The brake system generates a large amount of heat during operation. This leads to the fact that often the compounds stick together tightly. This also applies to guides that begin to jam. There is nothing good in this, as this can lead to serious consequences. The jamming helps ensure that the pads are permanently pressed against the disc. This leads to a significant overheating of the system. As a result, the pads burn, the disks become crooked. Yes, and the tire under such conditions can easily catch fire. That is why when servicing the support it is necessary to process the guides with special lubrication. Which one, we will understand in this article.

Properties of the lubricant for cylinders and guides

Since the node refers to the heavily loaded and during the process of heating up to 300 degrees Celsius, and with aggressive driving and higher, then the approach should be appropriate. Grease for brake cylinders should have the following characteristics:

• Operating temperature - from 150 degrees Celsius and above;
• Resistance to aggressive environment (salt, reagents);
• Minimum viscosity change with increasing temperature.

It is based on the above parameters, should be selected lubricant for the brake cylinders and guides. Benefit in the present time, the assortment is simply huge, so there should not be a choice of labor.

Copper grease for brake cylinders and calipers

It is the most common and popular among motorists. High temperatures are not afraid and are inexpensive, and this makes it so in demand. Most often used for machining disks, brake pads, as well as for staples and other elements of the brake system. It is worth noting that a copper lubricant is applied to the back of the product. If they are pads, then their front side should not be covered with any lubricant, this also applies to the discs.

The process of applying the paste is also extremely simple. For this, the treated surface is cleaned of dirt and corrosion. Further with the help of a brush lubricant is applied and evenly distributed over the entire surface. It is worth noting that it is sold in balloons, in this case it must be sprayed, having previously read the instructions for use.

Base base for high temperature lubrication

On the shelves of auto shops at the moment is simply a huge choice. But if you understand, then there are only 3 large groups:

• On a mineral basis;
• Synthetic base;
• A mineral or synthetic base with a small amount of metals.

If you understand what kind of lubricant should be used under the boot of the brake cylinder, then the one that is made on a synthetic basis is best suited. This is due to the fact that it is neutral to rubber and plastic products. Consequently, the anther does not corrode and is ideal for processing a brake piston or guide calipers. The base used provides a number of advantages, such as low volatility, high temperature threshold, insolubility in water and other liquids. In general, an excellent choice, though not always budget.

Where is cheaper the lubricant for the pistons of the brake cylinders on a mineral basis. But still it is better suited for guides, as it can withstand temperatures from -45 to +180 degrees Celsius.

Grease with the addition of ceramic particles

A relatively new development, which has already gained popularity. It is not cheap, but the stated advantages are very encouraging. The increase in lubricant performance is achieved due to the presence of a fine fraction in the ceramics. At the moment this is one of the best methods of protecting the brake cylinders and their seat from corrosion. In addition, the treated nodes exclude the possibility of sudden temperature changes, the formation of dirt and dust on the surface.

Despite the high cost of such products, it is extremely popular among motorists. Can be used as lubrication of rear brake cylinders, which are less loaded compared to the front ones. Among the most popular manufacturers of high quality the company "Liquid Moly" boasts. Well, now we go further and consider a few more important points.

How is the brake system serviced?

Often it is recommended to carry out complex lubrication when replacing brake pads or disks. There is nothing complicated here. First of all, we inspect the condition of the guides. We clean the fingers and seats from rust and treat it with a certain amount of grease. Suitable copper, graphite, etc. As for the piston, then the lubricant is needed to reduce friction and protect against corrosion. The surface of the part should be treated with a small amount of a ceramic grease. It effectively protects the surface from rust.

An extremely important detail is that it is worth regularly checking the condition of the anther. If it is torn, then no lubricant will help. First, you need to replace the rubber seal and then lay the lubricant. In addition, it should not be too much, as it begins to squeeze out through the anthers and cuffs, which is not good.

Advice from professionals

Many experts recommend not saving on lubricants for calipers and buying only proven products. For example, the optimum lubrication for pistons of brake cylinders on a silicone base. It is completely safe for anthers and at the same time is high temperature. Therefore, it works effectively both in winter and in summer. Car repair specialists often do not fulfill their direct duties. For example, when replacing shoes, calipers and guides should be cleaned, but nobody does it. Therefore, it is better to do this yourself, especially since there is nothing difficult and even a beginner can cope with this. Do not neglect the maintenance of the braking system, but also to look there every 500 kilometers of mileage, too, does not make sense. Inspect everything while replacing brake pads.

What kind of lubricant is better to take?

It is desirable to use different types of lubricant depending on the workpiece. For example, for guide rails, graphite grease is perfect . It is inexpensive and withstands high temperatures. Protects metal products from corrosion and prevents build-up. One of the most affordable options is TRW products.

The optimum lubrication for the pistons of the brake cylinders must be on a silicone or ceramic base. The best producer in this regard is Febi. Cheap and angry. But the anti-scratch Liqui Moly is not recommended for laying under the piston dust cover, as it can cause destruction of the rubber seal.

The anti-scratch paste is great for machining a brake pad plate and holding a staple. Usually this ends its use. Remember that the lubrication of the brake cylinder cuffs should not be done with pastes that corrode rubber seals. This can lead to the complete destruction of the piston and caliper.

Let's sum up the results

As you can see, there is nothing complicated in servicing the brake system of the car. But at the same time it is extremely important to regularly lubricate all the elements of the support, which each time work at high temperatures. Pay attention to the anthers of the guide fingers. They are also subject to wear and tear, resulting in a rather unpleasant knocking on uneven surfaces. This happens because the finger loosely hangs in the seat and is not held by the plastic sleeve.

As for lubricants, at present there are simply a huge number of them. Any paste for the lubrication of brake cylinders, if it is designed for this, is suitable for use. It is not recommended to lubricate the parts of the brake system with simple engine oil or a solid oil, etc. All this will not lead to anything good.

Many parts of the brake system with proper maintenance can serve 200-300 thousand kilometers or more, this applies to calipers, guides, pistons, etc. Pads and disks are more likely a consumable, but they are also desirable to be watched. All this will allow you to feel more confident at the wheel and know exactly what brakes will not fail, because there everything is oiled and checked. Often there is a problem with the jamming of the guides and the tight stroke of the brake cylinder, which occurs in 90% of cases due to insufficient lubrication. If you use grease for the anthers of brake cylinders every time you replace the brake pads, then you will not know any problems with the brake system of the car.
