Brake mechanisms are divided into disk and drum. The disc mechanism is a construction that consists of a calliper, one or two brake cylinders and two brake pads and disc. Calliper is a disc brake mechanism for attaching the brake cylinders. The calliper itself is obligatory mounted on the steering knuckle of the front wheel. There are two brake cylinders to which two brake shoes are attached. When driver presses the brake pedal, the pistons of the cylinders appear and begin tightly to push the shoes to the disc. And when he releases the pedal, the brake shoes and pistons return to their original position. This happens because of the easy knock of the disc.

Parts of the calliper are constantly subjected to water and salt from the road, as well as the influence of brake fluid from the brake system itself. Under these conditions, it is necessary to use special lubricants, which are designed for extreme operating conditions. Here are the basic requirements for the lubrication of the brake calliper. It is important the lubricant to be high-temperature with an operating temperature up to 180 degrees and above. The grease should be combined with plastic parts of elastomeric seals.

If you need to replace the brake calliper, you can buy it in our online store. We offer our customers a wide assortment of spare parts and short delivery terms. In addition to the brake calliper, in our online shop you can buy brake shoes, brake cylinder, clutch plate and brake drum.

All you should know about brake caliper: lifetime limits, common defects and their signs, tips and recommendations

The brake caliper has no specified lifetime limit. Usually, the brake caliper requires replacement if its elements, especially the piston, were exposed to corrosion and abrasive wear because of torn dust boots. Also, replacement is necessary in case of component deformation. Moreover, loosening of the fastening bolts, that results in displacement of the brake caliper from its mounting seat, may entail the installation of a new part.

Common signs of component defect are: changing of brake pedal resistance, its vibration, extraneous sounds when driving over bumps or braking. Skidding when stopping may also indicate brake caliper fault. In addition, working fluid leakages on a wheel may signify a defect.

Diagnostics of the brake caliper should be entrusted to specialists at a service station, as it is very difficult to define whether the component operates correctly without special knowledge, skills and equipment.

In order to replace the component, install chocks under the wheels, loosen fastening nuts or bolts of the wheel, lift the corresponding car side with a jack (depending on whether the front brake caliper is being replaced or the rear one), and fully unscrew the fasteners. Then demount the wheel, unscrew fasteners of the brake hose and install a plug to prevent brake fluid leakage. If the rear brake caliper is being replaced, then you should remove the parking brake cable. After this, disconnect the brake caliper from the steering knuckle. Then, install a new component and assemble all the parts in reverse order.

After installation, if necessary, refill braking fluid and be sure to bleed the braking system. It is recommended to inspect the brake hoses during replacement of the brake caliper and replace them, if damaged.
