Brake calipers with movable calipers are a common type of brake assembly fitted to passenger cars. For the caliper bracket to move smoothly, the guide brackets must be kept in perfect condition. Front and rear caliper guide bellows protect the elements from moisture and dirt, and extend the life of the components.

If the bellows are worn out or burst, the guides will rust and sour. As a result, the caliper guide moves in jerks, rust gets into the inner part of the assembly and the caliper needs to be replaced.

The material of the MAXGEAR brand Bellow, brake caliper guide

Like other parts for braking systems, the guide bellows are made of durable and wear-resistant materials. The service life of the elements depends on the driving style of the driver and the quality of the other parts of the calipers.

Bellows on the pistons of the brake calipers protect against the ingress of dirt, salts into the technological gap and subsequent oxidation. Their damage can be indicated by a characteristic drift of the car to the side or a deterioration in the rollover of a car due to jamming of the brake pistons. It appears quickly.
