During operation, the disc brake mechanism is constantly exposed to the negative effects of moisture, dirt and sand. As a result, the sealing cuffs on the pistons and the friction surface on the guide pins wear out, which leads to the blocking of the piston in the caliper or to its misalignment.

The usage of the AUTOFREN SEINSA brand Accessory Kit, disc brake pads

Metal springs are installed between the brake shoe and the caliper, which absorb the pad. They are also responsible for neutralizing the vibrations of the linings. Otherwise, when the pad is heated to 150-200 degrees Celsius, its base will expand and block the block, causing a skew and, as a result, wedging in the knot. This set of springs and plates is called a brake pad accessory kit. They are of two types, which, respectively, are designed for different types of calipers: for floating and for fixed. The first type of accessory kit consists of 4 springs that hold the pad parallel to the surface of the disc. For the fixed type, the repair kit for the pads is the guide pins and springs that press the pad to the caliper.
