Check and adjust the braking system

Check the brakes on a dry, flat road, the vehicle at various speeds with light and strong pressure on the brake pedal to avoid locking the brakes and sliding the tires.

In the braking process is influenced by three main factors:

- On different wheels are unequal conditions of tire grip, resulting in unequal braking forces. The air pressure and tire tread should be equal;

- Braking forces on the front and rear axles must be proportional to the action of the vertical loads;

- Violation of the wheels may be the reason that the car will be under braking pull to the side.

To check for brake fluid leaks, press the brake pedal with the engine running at idle speed and installing gear lever in neutral. If the pedal gradually falls at a constant pressure, then there is a leak in the system. Visually check for leaks and brake fluid level in the master cylinder reservoir. The slight drop in the brake fluid level is due to normal wear pads. Abnormally low levels of said leak in the system. The hydraulic system can be both internal and external leakage. If the brake fluid level is normal, check the length of the stem of the vacuum brake booster. If an improper length of the rod, adjust or replace the rod length.

Check the main brake cylinder in the following order:

- For damage and leakage of brake fluid around the master cylinder. Lowering the level of brake fluid can only talk about a leak. Abnormal condition is also moisturizing the surface of the master cylinder;

- Connect the pedal rod and the length of the rod. If they are in satisfactory condition, disassemble the master cylinder and check for stretching or swelling of the glands of the cylinder, and then - for wear rubber parts. If the swollen glands may use non-standard or contaminated brake fluid. If contaminated brake fluid is found, all metal components should be disassembled and cleaned, and all rubber - replace. All pipes should also be washed.

Improper brake fluid, mineral oil or the presence of water in the liquid may cause boiling of the brake fluid or damage the rubber components. If the main seals of the piston in the master cylinder are swollen, then the rubber components are corrupted. If tire wear is detected, disassemble all the hydraulic parts and wash them with alcohol. Before assembling the parts dry using compressed air. Replace all the rubber parts in the system, including the hoses. At work, check the brake fluid in the pads. If liquid is detected, replace the gasket.

If the condition of the piston seals of the master cylinder is normal, check for leaks or overheating. If these conditions are not found, drain the brake fluid, refill the master cylinder, and again drain the system.
