The experts gave helpful advice to motorists.
The role of the Park brake system is high – in addition to keeping the vehicle in a stationary state, it duplicates the main, hydraulic. In accordance with the law and applicable regulations, every vehicle must be equipped with a redundant braking system. In case of failure of the main it leaves the opportunity to stop the car.
From the time of the Union, many Ukrainian motorists do not use the Parking or as it is called, the handbrake”handbrake”). Especially this sin of owners of cars with automatic transmission, in which there is a mode “Parking” (P). The cars with the “mechanics” often just leave in gear. Many believe that the way they “protect” the hand brake mechanism and less wear. Meanwhile, to the Parking brake system remains operational, just like any other moving mechanisms, it is necessary to regularly use. Whether the Parking brake is electrically operated or lever system, the cable is usually the first thing fails, it is because they do not use. In case of malfunction of the Parking mechanism can suffer and the main braking system. If the Parking brake mechanism is associated with a service braking system, in case of a failure, the reduced effectiveness of the rear brakes.
Another reason to always use the handbrake and maintain is security and reliability while setting the car into the Parking lot. Any driver with an automatic gearbox probably heard or experienced, if not fully stop at statement on the position of “Parking”, you can feel the rattle and jerk. This is the locking mechanism of the transmission, and it does not guarantee trouble-free braking of the car – the load on it may be too high. In the same car with a manual transmission with the setting “transfer” wheels remain rigidly connected with a stationary engine. But if a strong external impact, the crank wheel may cause rotation of the motor, including backwards, which can lead to unpleasant consequences and costly repairs, e.g., timing. Also in this case the spring loaded damper torsional vibrations of the clutch plate or springs dual-mass flywheel. Because of this constant load, these mechanisms also prematurely fail.
The only justification for the failure to use a “Parking brake” can be found in the winter, when after washing or when high humidity and variable weather, water can get into the mechanisms of the Park brake system to freeze and immobilize them. Therefore, in such circumstances really is not recommended to leave the vehicle in Park.
Among other possible reasons for the failures of the system – a violation of the functional characteristics of the sheath. Over time, inside it is subjected to moisture and dirt, corrosion occurs, and cables along with a sour shell. If the rope has lost mobility, he is not moving inside the shell and entirely with her. There are times when the shell melts, as the cables are often held in close proximity to the exhaust system. It also reduces the mobility of the cable. In any case, the Bosch experts recommend simultaneous replacement of the structure as a whole, the cable together with the shell.
A common fault is the tension of the cable beyond measure. In this case, it is impossible to carry out adjustment appropriately, hence, the brake will not work and keep the car in a stationary position. In addition, if the cables are highly elongated, or, conversely, over-torqued, the rear brakes will not work properly. When replacing the cables on the new it is also important to properly adjust their tension.
Depending on the design, the adjustment can be performed from the interior side lever or under the car. In implementing this process, it is necessary to follow recommendations of manufacturers. Except for the tension adjustment of cables, the Parking brake system is considered maintenance free, but she should be given the same attention as the service braking system. To do this, manually pulling the cables, and a visual estimate of their mobility. To verify the performance of the Parking braking system on the brake stand.
The service brake system can be carried out at the stations of a network of Bosch Car Service, where there is special equipment and experience to fix any problems in the brake system of cars of different brands and models.
