Good brakes are a guarantee of safety. The braking system should not be unreliable or operate erratically - this is a self-evident fact that does not need to be proven. It must be immediate and work properly, because even a small failure of the braking system can cause an accident.
The braking system has the following structure:
The brake mechanism is designed to provide the braking force needed to slow and stop the car. Cars are fitted with friction-type braking mechanisms that work by harnessing the force of friction. The brake mechanisms of the working system are mounted directly on the wheel. The parking braking mechanism may be located behind the gearbox or transfer box.Depending on the design of the friction component, different types are distinguished:
The brake mechanism consists of a rotating and a fixed part. The rotating part of the drum mechanism is the brake drum, the stationary part is the brake pads or shoes.The rotating part of the disc brake mechanism consists of the brake disc, the fixed part of the brake pads. Disc brake mechanisms are usually fitted to the front and rear wheels of modern passenger cars.The disc brake mechanism consists of a rotating brake disc and two fixed brake pads mounted inside the brake caliper on both sides.The brake caliper is fixed to the support frame. The caliper is fitted with thrust cylinders which press the brake pads against the disc when braking with hydraulic power. The brake disc becomes very hot when braking. The brake disc is cooled by air flow. In order to better dissipate the heat, holes, grooves or an "open" structure are made in the disc. Such a disc is called air-cooled. To increase the efficiency of the brakes and to guarantee resistance to overheating, ceramic brake discs are used in sports cars.The brake pads are pressed into the brake caliper by spring elements or other special methods. Friction pads are attached to the pads. In modern cars, the brake pads are fitted with a wear sensor. The following brake designs are used in car braking systems:
Mechanical drive is used in a parking brake system. Mechanical actuation consists of rods, levers, cables and springs that connect the parking brake lever to the rear tyre brakes. It includes:
On some car models, the parking brake system is activated by a pedal, the so-called foot-operated parking brake. More recently, electronic control has been widely used in the parking brake system, and this system is called the electromechanical parking brake. Hydraulic control is the main type of control in a service brake system. The structure of the hydraulic steering system includes:
When the brake pedal is depressed, the load is transferred to the brake booster, which creates additional force on the master cylinder. The master cylinder piston pushes fluid through the tubes to the wheel cylinders. This increases the fluid pressure in the brake system. The pistons in the wheel cylinders transfer force to the brake pads on the surface of the discs (or drums).As the pedal is pressed further, the fluid pressure increases and the brake mechanisms are released, resulting in slower wheel rotation and braking forces at the point of contact between the tyres and the road surface. The more force applied to the brake pedal, the faster and more effective the braking of the wheels. During braking, the fluid pressure can reach 10-15 MPa.When the braking is stopped (brake pedal release), the spring action returns the pedal to its original position. The piston of the master cylinder also returns to its original position. When the fluid burns, the pistons pull the brake pads off the discs (or drums). The brake fluid from the wheel cylinders flows through the tubes back to the master cylinder. You can always contact us to repair your car's brake system in Espoo, Finland.
Braking system problems can manifest themselves in a number of different ways:
If one or more of these symptoms occur, we recommend that you contact us immediately for your Volkswagen brake system repair in Espoo. Contact us by phone: +358103380980
The technique for restoring braking system function depends largely on the nature of the problem. If you are not familiar with the brake system and do not have experience in repairing it, we recommend that you do not attempt to repair it yourself. Contact our car service "Volkkarihuolto". We can competently diagnose the problem and carry out the brake system repair in our garage in Espoo.
