How to install brake caliper repair kit?

Brake caliper lifetime depends on quality of greasing and timeliness of the car braking fluid replacement.

Brake caliper repair consists in replacement of its components that caused brake system failure. For this you should dismantle the part, clean it from old greasing, apply new one, perform replacement of the defective element and install a new brake caliper repair kit. Caliper dismantling involves removal of the wheel and the retaining spring, pinching the brake hose, removal of the guides and the lower bolt which fixes the caliper to the bracket. Then you should remove the component itself and detect the element that caused the failure. In case of a serious fault, replacement of the component in assembly is performed.

The brake system of the car has a rather complicated structure. If you don’t have special skills, there is a major risk of system elements damage even when doing an insignificant repair. That is why all works on repair and replacement of the brake caliper are recommended to be entrusted to service station specialists.
