The main malfunctions of the brake calipers in the car

Most cars today are equipped with a fairly simple brake system with a pair of disc and drum mechanisms. One of the most important elements of this system are the brake calipers. Autopro experts note that if the caliper is heavily worn, it will no longer press the pads to the disc / drum normally. Soured caliper guides, worn pistons, worn out pads - these are some of the possible problems with brake calipers. We invite you to learn more about them.

Briefly about possible breakdowns

With regular maintenance, brake calipers can cover over 150 thousand km. According to experts, a complete replacement of the caliper is required only in extreme cases. Often, some of its elements fail. In this case, the driver will face the following problems:

The appearance of metallic noise, squeak when braking;

Uneven pad wear

Reduced brake fluid level;

The withdrawal of transport to the side when decelerating;

Strong vibration of the brake pedal;

Brake sticking;

"Failure" of the pedal or "sticking" in the lower position.

The driver can check the brake calipers themselves. It is advisable to check a pair of calipers on the same axle at once, removing the wheels one by one and inspecting the mechanism for mechanical damage and signs of corrosion. If there are large foci of corrosion on the caliper body, bracket, pistons and guides, problematic parts will have to be replaced. The caliper is also changed if traces of wear are found, such as corrosion pits.

Service Features

Having the necessary tools and auto chemicals, the driver can extend the life of the calipers. From the tools you will need keys and knobs, a set of screwdrivers, optionally a screwdriver. To clean the caliper, sandpaper and universal cleaners are suitable. Also, the driver should get lubricants for the calipers. Here's what you can do:

Dismantle the caliper partially or completely, clean it from dirt and oxides;

Replace old brake pads (check for even wear);

Replace pistons and guide pins or only their seals;

Lubricate pistons, guides and pad contact areas.

Caliper parts can be found in special repair kits. As a rule, replacing pads and worn out guides is enough to “reanimate” even a worn caliper. If necessary, the driver can replace the caliper bracket and return springs.

Briefly about the main

The performance of the brake system will depend on the condition and general quality of the brake pads. The pads are arranged simply: friction material, a metal plate. Often pads are equipped with wear sensors. Before you pick up a new part, we advise you to understand the classification. Columns are like this:

Semi-metallic. Wear out the brake disc, work worse at low temperatures;

Low metal. The above disadvantages are almost not manifested;

Ceramic. They boast a stable coefficient of friction and reliability;

Organic. Quiet and grippy, but wear out quickly.

Brake pads are also divided into several categories. The highest quality products fall into the category of components for delivery to the conveyor of the automaker. The remaining products are conditionally divided into 2 categories: mid-budget and inexpensive. The quality of performance of the latter is not always pleasing, but there are exceptions.

How to make the right purchase

To begin with, the driver should decide on the budget for the purchase. Next, you need to choose the right pads. You can search both by the VIN code of your vehicle, and by its technical parameters or part number. From the selection of suitable lasts, remove those that did not fit into the budget. Now it's up to you: decide on a brand and make a purchase.

Many motorists agreed that it is not advisable to save a lot on buying brake pads. We advise you to pay attention to the products of such brands: Akebono, TRW, Nisshinbo, Jurid, Hi-Q, Ferodo and Brembo. These manufacturers produce both relatively budget pads and more expensive ceramic models. If you prefer an aggressive riding style, then carefully study the description of each set of pads. The options that are sure to suit you are usually found in the Sport, Racing and Performance lines.
