A brake caliper is a mechanical part that is an integral part of a vehicle's braking system. He pushes the pads against the brake disc to slow down the wheel. To do this, the caliper receives the oil from the hydraulic system under pressure and changes it into mechanical force with the piston(s). Then, the latter exert pressure on the pads to press the disc. These elements must not deform in order to have a progressive and controlled braking intensity.
The different types of brake calipers
There are different types of car brake calipers:
- The fixed caliper provides a better distribution of braking force over the entire brake disc. Indeed, the pistons are placed on each side of the disc on which they exert pressure;
- The floating caliper slides along 2 rods attached to the rocket so that the pressure of one or both pistons is only applied on one side;
- The sliding caliper consists of a brake pad attached to a clamp. It is the sliding device that takes the pressure exerted by the pistons;
- The ring caliper consists of 2 pistons, each with its respective role: one pushes the brake pad inside and the other slides outwards on the disc.
The importance of changing your brake caliper
Your brake caliper is regularly subjected to wear and tear due to its mechanical action. The latter must be seriously considered since you cannot always avoid dangerous driving, splashing water and salt on the road or winding roads.
So, if you notice a recurrent and unusual braking noise or your brake pedal becomes soft, it is essential to change your brake caliper. The braking system of a vehicle is not something to be taken lightly, it is important for your own safety as well as that of others (passengers or vehicles).
When to replace your brake caliper?
Replace your brake caliper when it is defective, seized or locked. It is not always easy to know the exact time to change your caliper and it is even less so if you have no knowledge of mechanics.
However, the following factors can come to your attention: immobile pads, a permanently heated brake disc, corroded pistons, a braking feeling without depressing the brake pedal, etc. When you see that something is wrong with your braking system, consult a professional directly so that they can make a precise diagnosis.
