5 tips on how to use and replace them
Despite the fact that this car part doesn’t have a specified service life, it is necessary to inspect its dust boots at least once a month. If there are any damages to this protective element, it is recommended to replace it as soon as possible. Otherwise, a brake calliper piston will fail quickly because of dust and dirt from the road surface.
It is preferable to have new parts installed at a service station. Working with components of this assembly requires extreme precision.
To ensure a longer service life for this car part, it is important to avoid increasing its stroke. This happens when worn brake pads aren’t replaced timely.
When new pads are fitted, it is recommended to clean the contacting surface of brake calliper pistons and apply special lubricant to it. It’ll help to get rid of extraneous noises when brakes are applied.
The fluid in the system should be replaced at the intervals stated in the vehicle manual. Usually, it is at least twice a year.
Malfunctions of brake calliper pistons, their causes and symptoms
Corrosion damage. This, as a rule, is caused by moisture getting on the part through a damaged dust boot. This often happens when a vehicle hasn’t been used for a long time. Signs of corrosion are easy to notice during regular vehicle inspection.
Deposits on the polished part of the piston. They appear due to the low quality of the working fluid or its untimely replacement. This defect causes the parts to get stuck. As a result, pads move away from discs much slower which causes overheating of the components, unintentional braking and increased fuel consumption.
Mechanical damage. The polished part of the piston becomes scratched if unsuitable tools or foreign objects are used to eliminate contaminants. In particular, this defect can appear when metal tools are used instead of soft cloth. Cracking leads to failures in the system performance and premature wear of its parts.
