Major works in maintenance brake system

In this article we will tell you what principally responsible for maintenance of the braking system. With daily maintenance, must inspect the system for tightness of all connections brakes. On detecting leakage of air or fluid from the system it must be eliminated. The brakes checked on the move the car when it detects a fault, the brakes must be repaired immediately. First you need to check the tightness of the brake system. If you often have to top up the brake fluid in the system with hydraulic drive, from this we can conclude that there is a leak. Exactly where the liquid can be determined follows careful visual inspection. Working cylinders must be removed to inspect the brake drums. If you stumbled upon a loose connection, it should pull up, a defective cuff - is replaced by a new one. Places where the air outlet can be determined by the characteristic hiss in the compounds. Is there another way how to define an air leak - is necessary to dilute soapy water and fluff them all connections where leaks will begin to form bubbles. Eliminate this leakage, you can replace the damaged part (hose pipe nipple, etc.) or if it can be done to tighten the existing one. The fault is judged by checking the brakes while driving. Serviceable can be called a brake, which simultaneously and completely inhibit the car after pressing the brake pedal. They should provide braking in accordance with the "Rules of the road. Handbrake will be corrected if it will hold a car (no matter how much one is loaded) on the rise with a slope of 16%. If the stopping distance at full pressure on the pedal is quite large, and the wheels at this time does not slow down until the "Hughes", you should check and adjust the brakes or the same amount of free stroke the brake pedal. If braking is leaving the car to the side, it suggests that the brakes of your car is defective. Eliminate this problem can adjust braking mechanism, and stripping or replacing brake pads. If your car is poorly dispersed or traveling coast-down, it becomes hot drum mechanism or the hub - this may be due to the fact that your brakes poorly disinhibited. In this case, you have to check and, if necessary, adjust the pedal free play and the gaps between the brake drums and pads. Often when this is removed the brake drum and inspect its return spring. If they are broken, need immediate replacement. In cars, on which the mechanism is installed with hydraulic braking system, compensating the hole brake cylinder must be cleaned and when it is necessary to pay attention to the movement of the pistons in the cylinder and the state of the cuff. In a car with a pneumatic actuator loosely prilegshy valve brake valve replaced by a new or clean, also need to lubricate the shaft bearings Expansion fists. What to do if the brake fails Beadle, and inhibition occurs after three or four clicks? First you need to check the brake actuator and to identify whether there is looseness in the joints. If the brake fluid is leaking, the joints need to tighten, and hoses replaced. After that, the brake actuator must be pumped to remove him from the news the air. This should be done in the following order: First you need - check your brake fluid level in the reservoir cylinder, it should be not less than 15-20 mm below the upper edge of the opening of the bay. If necessary, the fluid is topped up. Then you need to remove the protective rubber cap relief valve on the brake cylinder, rear-right wheel, instead there should be put on one end of the hose with a length of 35-40 cm, the other end must be omitted in a jar with brake fluid. Brake valve should turn away at 20 rpm, and then sharply push the brake pedal several times. Such an operation should be performed as long as the brake fluid will flow not from the valve without air bubbles. Pedal should hold while you tighten the bypass valve, hose off, the rubber cap put in place. Later in the same way you want to remove the air in all the remaining wheels. Once you've pumped all-wheel drive, brake fluid in the brake master cylinder should be topped up to the required level. When you do the maintenance for the first time we have to verify how the pedal brake, if necessary - to adjust. Shplintovku finger rod in the brake chambers must also be checked and condensate from the tank to pull the air. Adjust the brake in the following sequence: wheels, brakes that need to be adjusted, it is necessary to raise the jack. Rotation of the worm box, a device for adjustment, clockwise deploying shaft Expansion knuckle down to a braked wheel. The worm, then, turn clockwise until the wheel is abhorrent to begin to rotate freely. It is along the same lines regulate brake pads all the other wheels. Of brake-testing course. Adjust the wheel brake, you must change the length of the stem diaphragm brake chamber by rotating its tip is unacceptable. Handbrake on the car should be regulated as follows: Brake lever should move to full release. Jacks to lift the right rear wheel and tighten the screw until the lock-up drum, after which it will need to loosen up to the moment when the drum is able to easily rotate. Rail drive must be installed on the first tooth, the cable equalizer need to move the adjusting nut, after clicking on the line - to tighten the locknut. If done correctly, the full braking the rear wheels should make for pulling the hand brake for no more than 2 / 3 full speed. All the above activities are the major works in the maintenance of the braking system, they should be prodelyvat for each inspection. And remember that the degree of serviceability of the brakes depends on your life.
