6.1. General information

General information
Mitsubishi cars Outlander are equipped with two independent brake systems: working and lay. The first system equipped with a hydraulic drive, provides braking at the car movement, the second – затормаживает the car on parking, its drive mechanical.
On the car apply working brake system with diagonal division of contours that considerably increases safety of driving. At refusal of one of contours of working brake system the second contour providing a stop of the car, though with smaller efficiency is used. Both contours are put in action from one pedal which fastens to a body arm. In a hydraulic drive, besides a pedal ытормоза, the vacuum amplifier, the main brake cylinder, brake mechanisms of lobbies and back wheels together with working cylinders, pipelines are switched on.
The drive of lay system is carried out on brake mechanisms of back wheels.

Vacuum amplifier
It is established between the mechanism of a pedal of a brake and the main brake cylinder, when braking at the expense of depression in an inlet pipe (receiver) of the engine through a rod and the piston of the first chamber of the main cylinder creates the additional effort proportional to effort from a pedal. In a hose, connecting the vacuum amplifier with an inlet pipe (receiver), is established the return valve. It holds depression in the amplifier at his falling in an inlet pipe and interferes with hit of a toplivovozdushny mix in the vacuum amplifier.

Main brake cylinder
The main brake cylinder of a hydraulic drive of brakes consists of two separate chambers connected to independent hydraulic contours. The first chamber is connected with right forward and left back the brake mechanisms, the second – with left forward and right back brake mechanisms.
The main cylinder is supplied with a tank which internal cavity is divided by a partition into two compartments. Each compartment feeds one of chambers of the main cylinder.
By pressing a brake pedal pistons of the main cylinder start to move, working edges of cuffs block compensatory openings, chambers and a tank are separated and replacement of brake liquid begins. On the cars equipped with anti-blocking system of brakes (ABS), in openings of the main brake cylinder are screwed the union of the tubes bringing brake liquid to the hydraulic ABS block.
On cars without ABS on the main brake cylinder regulators of pressure which when braking correct pressure of brake liquid in back brake mechanisms, excepting possibility of advancing blocking of back wheels are established. It is reached by proportional reduction of pressure in back brakes in relation to pressure in lobbies.

Forward brake mechanism
Brake mechanisms of forward wheels disk, with automatic adjustment of a gap between brake shoes and a disk, with a floating bracket. The mobile bracket is formed by a support with the one-piston working cylinder. Directing blocks it is attached by bolts to a rotary fist of a forward suspension bracket. The mobile bracket from below is attached by a bolt to directing finger which is established in an opening directing blocks; from above the bracket moves on the directing pin screwed in directing blocks. Directing finger and a pin are greased with konsistentny greasing and protected by rubber covers. In a cavity of the wheel cylinder the piston with a sealing ring is established. At the expense of elasticity of this ring the optimum gap between blocks and the ventilated disk which surface is protected by a brake board is supported. When braking the piston under the influence of pressure of liquid presses an internal block to a disk, as a result of force of reaction the support moves on fingers and the external block too nestles on a disk, and force of pressing of blocks appears identical. At a rastormazhivaniye the piston at the expense of elasticity of a sealing ring is taken away from a block, between blocks and a disk the small gap is formed.

Back brake mechanism
Brake mechanisms of back wheels drum-type, with automatic adjustment of a gap between blocks and a drum. Brake shoes are put in action by one hydraulic working cylinder with two pistons. The optimum gap between a drum and blocks is supported by the mechanism of automatic adjustment of a gap between a drum and blocks.

Parking brake
The parking brake is put in action mechanically, consists of the draft lever with an adjusting nut and two cables. Back tips of cables are connected to razzhimny levers of a drive of the parking brake, established on back brake shoes. The lever fixed between forward seats on a tunnel of a floor, is equipped with the mechanism of adjustment of a tension of cables. Forward tips of cables are connected to the equalizer of the mechanism of a tension.
The parking brake does not need special leaving. At maintenance check degree of wear of its details, be convinced of serviceability of teeths of sector and a doggie. Excessively worn-out details replace.
At detection of break of covers or a provolok of cables it is necessary to replace them new.

Anti-blocking system of brakes (ABS)
General information
On cars the anti-blocking system of brakes (ABS) with electronic system of distribution of brake forces (EBD) is established. ABS regulates pressure in brake mechanisms of all wheels when braking, preventing blocking of wheels; provides reduction of a brake way at emergency braking with preservation of stability and controllability of the car.
The anti-blocking system of brakes includes the electronic ABS control unit, the hydraulic block, the vacuum amplifier, the main brake cylinder, sensors of speed of rotation of wheels and pipelines.
The electronic control unit and the hydraulic ABS block, united in the uniform module, are established in a motor compartment under the vacuum amplifier of brakes and fixed on the front panel (for descriptive reasons the photo is made at the removed vacuum amplifier of brakes).
During car braking the electronic ABS control unit receives a signal from all sensors of speed of rotation of wheels and defines, what wheel is at present on the verge of blocking. On the basis of the received signals the electronic block puts in action the corresponding electromagnetic valve in the hydraulic block for ensuring demanded pressure in the pipeline of the corresponding wheel.
Functions of self-diagnostics and emergency operation of work are built in the electronic ABS control unit. In case of detection by the electronic control unit of malfunction in system in a combination of devices the alarm lamp of malfunction of anti-blocking system of brakes lights up and in memory of the electronic control unit the corresponding code of malfunction which is read out by means of the special diagnostic device (scanner) registers. At malfunction emergence in ABS operability of brake system remains, but blocking of wheels when braking car is possible.

Anti-blocking system of brakes (EBD)
The electronic system of distribution of brake forces (EBD) is a subsystem of ABS which serves for ensuring effective coupling of back wheels with a road surface.
In the presence of EBD system the brake effort is supported near optimal and regulated by electronic system that allows to do without a pressure regulator.
The electronic system of distribution of brake forces copes the electronic ABS block. At car movement the system of distribution of brake forces constantly defines degree of a proskalzyvaniye of each wheel of the car and regulates pressure of working liquid in brake mechanisms of forward wheels so that it exceeded pressure in brake mechanisms of back wheels. Blocking of back wheels is as a result prevented and higher efficiency of operation of brakes is provided.
In case of malfunction of EBD system in a combination of devices the alarm lamp of a condition of brake system (with an optical filter of red color) lights up.
