Diagnosis of braking systems in motor vehicles

During the operation of the vehicle to monitor the serviceability of the brake system, because any malfunction of the braking vehicle, often, can lead to unpleasant consequences. How are diagnosed brake car, you can learn from this publication. Many drivers do not find time or too lazy to look under the hood of his car, and check the fluid level in the brake reservoir. But there can come a moment when the brake fluid level will drop to zero, and the next time you press the brake pedal, the driver will already be compressed no brake fluid and air. Of course, inside the cabin the driver simply notice a reduction in braking efficiency while driving, but if you're on time to control the brake fluid level, then you will be calmer, and other road users safer. You may be wondering, as far gone as brake fluid? Over time, any liquid evaporates slowly, and the details of the brake system is not eternal, for example, rust and vibration lead to loss of tightness of pipes and hoses of hydraulic drive, wear cuff sealing the pistons of cylinders. Wet footprints on the wheels or under your car, coinciding with the location of parts of the brake system malfunction, and you should abandon the trip, and eliminate this problem. Braking of the car - is a process of transition of the kinetic energy of a moving car into heat energy due to friction forces. Therefore, while the details of the working mechanisms in the brakes, and the space around, very hot. In this case, brake fluid, which is next to the cylinders and tubes is also significantly heated, and may at some point boil. After that, according to the laws of physics, the brakes you will not have to as long as you do not compress the air in the cylinders, hoses and tubes, as air bubbles, in contrast to the fluid will be compressed, and not to transfer pressure to the actuators. Once you have all the same, stop the car, you should understand why all this happened, and it is now to eliminate air bubbles from the brake system. Reasonable alternative braking, especially on steep and downhill - engine braking to avoid such troubles. If you will often push the brake pedal to increase the heating of parts, and this can lead to faulty brake system. How to diagnose the presence of air bubbles in the brake fluid that may occur as a result of depressurization of the hydraulic actuator, or boiling liquid? The first sign of the presence of air in the drive - the brake pedal will be "soft", and the rate of inhibition is reduced, while in a few quick pedal, it gets tougher. To get rid of air in the system, you need to release a little brake fluid with air bubbles, then pour the fluid in the brake reservoir. Another common problem with the brakes - the brake pedal becomes stiff, and the necessary effort to push it. If the engine is not working and the car in tow, so it should be, because power brakes will not work with the engine off. If the engine is running and the brake pedal became tight, it means that the amplifier is faulty and it needed repairs. Properly tuned parking brake provides retention vehicle on a slope of 23% for three or four clicks release lever. If the parking brake does not hold a machine requires replacement of cables, or its regulation. It is also possible to change the brake pads. Most of the work necessary to debug the brake system you can make yourself, but for serious faults better to turn to professionals, still with the brakes be trifled with. The main brake system malfunction. Car pulling to one side when braking - possibly excessive wear or lubrication lining pads of a wheel brake mechanism, the problem is the wheel brake cylinder. In this case a replacement of a defective cylinder, or washing contaminated shoes. Vibration or noise when you press on the brake may arise as a result of the following faults: the uneven wear of the brake drums or discs, excessive wear on brake pads, loose or broken return spring rear brake pads, brake pollution. In this case you need to replace worn or damaged pads, drums, discs and springs on the new, flush contaminated pads. "Soft" brake pedal (increased pedal) can occur due to: the presence of air in the hydraulic drive system, heavy wear on brake pads, brake fluid leakage. In this case, as mentioned above, is required to pump hydraulic system, thereby removing the air from the system, replace damaged parts, to avoid leakage of brake fluid, replace brake pads.
