How to care for a brake system of the vehicle. How to take care of the brakes
Reliable and trouble-free operation of the braking system of the vehicle directly depends on the attention and time spent by the driver at her service.

Signs of malfunction of brake system
Malfunctions in the brake system experienced driver will determine at the initial stage of their occurrence by direct and indirect sign of an unstable brake. Beginner same motorist may not be aware of the faulty brakes until, until one not so great moment the brake pedal from clicking on it will go down to the floor, having absolutely no impact on the speed of movement of the machine.
The symptoms and signs of a defective brake system:
— increase the working stroke of the brake pedal;
— periodic failures and excessive firmness of stroke;
— leaving the car in the direction from initial direction of motion during braking;
— increase braking distance;
— a sharp brake and an abrupt locking of the wheel;
— the beating of the wheels during braking;
the squeal and hiss of brakes.
Regular check the level of brake fluid in the reservoir should become a habit. Don't lay unreasonable expectations on the level sensors, which are equipped with brake systems of almost all cars, because electronics can fail or trivial lie, signaling that the tank with brake fluid is full.
Another very useful habit is inherent in the mainly experienced drivers of old used cars. It consists in careful study of the surface of the asphalt in the Parking lot the car after leaving it out of the garage or out to the Parking lot. Stains oily liquid will indicate not only the possible leakage of brake fluid, but also on a possible malfunction in the lubrication system or cooling system.
Do not miss the opportunity to call on the overpass or hoist to perform an inspection of piping and connections of the brake actuator.
Perform regular brake fluid. Because it has a relatively high hygroscopicity, after 3-4 years of operation, the brake fluid absorbs considerable amount of moisture that is present in the environment, which leads to a significant deterioration of its performance properties.
the Degree of wear of brake pads
Worn brake pads can cause not only decrease the effectiveness of the braking system, but also cause jamming of the pads or its destruction. The result in either case would be disastrous, no matter what happens – wheel lock or a failure of the braking system.
Some automakers equip brake system with electronic sensors that send to the control unit of the vehicle signals indicating the wear of the friction layer, other mechanical control devices for the issuing in case of wear pads sharp creaking sound.
The wear pads can be judged by a special cross-stripes deposited on protective pads. Erasing pads to the base of these furrows shall identify the need to replace the brake pads.
The condition of brake pads can be checked without removing the wheel. To do this, simply hold your finger on the inner side of the rim. Evidence of the normal condition of brake pads will be the presence of her coal dark patina. If the finger will remain small shiny metal inclusions, then the friction pad is worn out order.
Free and stroke the brake pedal
Too big free wheeling of a pedal of a brake reduces its working stroke, resulting in reduced efficiency of the braking system. Insufficient importance of free pedal travel is fraught with incomplete disinhibition of the wheels when you release it.
The nominal value of the free and the working stroke of the brake pedal is specified in the Datasheet or description of each car and their validation can be performed using a regular ruler.
If in the process of checking the working stroke of the brake pedal you find that pressing the pedal until it stops moving smoothly to the floor, immediately check the main brake cylinder and check the hydraulic system for leakage of brake fluid.
Good luck to you! No nail, no wand!
