The brake caliper is attached to your car’s wheel hub and houses the brake pads and pistons. Your Volvo 850 brake calipers are an essential component in the overall success of your vehicle’s disc braking system. The caliper’s brake pads are the objects that the pistons force into contact with the brake’s rotors, generating a great deal of friction that is necessary in order to halt the progress of your car.

They are basically mini hydraulic clamps that bring the pads and the rotors to together to achieve the slowing or stopping that is needed. Your Volvo 850 brake calipers work just like the calipers on a bicycle do. When the handgrip brake on a bicycle is depressed, cables pull the calipers together.

The calipers do not actually contact the tires to cause the necessary friction, but the rubbers pieces attached to the calipers do. These rubber pieces act just as brake pads do in the scheme of the disc braking system. In a car, however, when you hit the brakes a high-pressure fluid travels from the master cylinder to the calipers, forcing the pistons downward, causing the brake pads to come into contact with the brake rotors, producing the desired result. Your Volvo 850 brake caliper has to absorb a massive amount of force in order to achieve this end, so you can imagine how much pressure is exerted upon each one. Calipers are highly durable, very reliable parts, but just like any other component on your vehicle, there’s always a chance, no matter how slight, that something can go wrong with it.If it does, search our site for the right Volvo 850 brake caliper for you car.
