Check of serviceability of functioning / tightness, removal and installation of the amplifier of brakes

Components of installation of the vacuum amplifier of brakes


The servo-driver of the vacuum amplifier of brakes does not need regular service, except for periodic checks of a condition of a vacuum hose. Components of installation of the vacuum amplifier of brakes are presented on an illustration above.

Check of serviceability of functioning of the vacuum amplifier

 PERFORMANCE ORDER

1. Without starting the engine, several times squeeze out a pedal of a foot brake. Make sure of absence of changes in size of a reserve course of a pedal (see. Section Adjustment of a pedal of a foot brake).
2. Holding a pedal squeezed out, start the engine. If right after start the pedal slightly "fails", therefore, the vacuum amplifier of brakes works regularly.

Check of tightness of the vacuum amplifier

 PERFORMANCE ORDER

1. Start the engine for few minutes, then muffle. Several times slowly squeeze out a pedal of a foot brake. If the pedal course with each squeezing is gradually reduced, being stabilized on the third or fourth muscleman, means, tightness of assembly of the vacuum amplifier is not broken.
2. Squeeze out a pedal of a foot brake at the working engine. Holding a pedal squeezed out, muffle the engine. If 30 seconds of keeping of a pedal later pressed its reserve course does not change, therefore, tightness of assembly of the vacuum amplifier is not broken.

Check of the hydraulic amplifier

 PERFORMANCE ORDER

1. Check completeness of a charge of the storage battery.
2. At the switched-off ignition press a brake pedal not less than 4 times.

In process of pressure decrease in system the course of a pedal will decrease, and the ongoing effort – to increase.

3. Establish manometers and an effort measuring instrument (address to an accompanying illustration) and pump over brake system (see. Section Adjustment of a pedal of a foot brake).
4. At the idle hydraulic amplifier of brakes press a brake pedal with 245 N.Davleniye's effort in a contour of forward brakes there should be more than 14.5 bar, and in a contour of back brakes – ulevy. Increase effort of pressing to 343 N, thus pressure in a contour of forward brakes should be more than 20.6 bar, and in a contour of back brakes – zero.
5. At the working hydraulic amplifier of brakes include ignition and wait, while the pump of the hydraulic block will not cease to work. Press a brake pedal with 49 N.Davleniye's effort in a contour of forward brakes there should be 13-25 bar, and in a contour of back brakes 16-28 bar. Increase effort of pressing to 98 N, thus pressure in a contour of forward brakes should be 32-45 bar, and in a contour of back brakes – 35-47 bar. Increase effort of pressing to 147 N, thus pressure in a contour of forward brakes should be 53-65 bar, and in a contour of back brakes – 55-67 bar. Increase effort of pressing to 196 N, thus pressure in a contour of forward brakes should be 72-84 bar, and in a contour of back brakes – 75-87 bar.

Removal of the vacuum amplifier

 PERFORMANCE ORDER

1. The block of the vacuum amplifier of brakes is not subject to regenerative repair and in default should be replaced assembled.
2. Disconnect the vacuum hose brought to the amplifier from the inlet pipeline of the engine. Try not to damage a hose, removing it from the union on assembly of the amplifier.
3. Give fixing nuts and carefully remove from assembly of the vacuum amplifier the main brake cylinder (see. The section Removal and installation of the main brake cylinder (GTTs)), try not to allow peregibaniye and twisting of hydraulic lines.
4. In salon of the car find knot of connection of a rod of a pusher of the vacuum amplifier to a pedal of a foot brake, – (in case of need use a pocket small lamp). At first disconnect a returnable spring, then take шплинт, liberate a cylindrical pin and disconnect a cutting finger of a pusher from the pedal lever.
5. From salon at the left under the dashboard give four nuts of fastening of assembly of the vacuum amplifier to a partition of an impellent compartment (address to an accompanying illustration), – in case of need use a pocket small lamp.
6. Pass to an impellent compartment and remove assembly of the vacuum amplifier from a back partition. Pull assembly strictly on an axis of its installation before complete liberation of a rod of a pusher. Take assembly from an impellent compartment.

Installation and adjustment of the vacuum amplifier

 PERFORMANCE ORDER

1. Installation is made upside-down. All fixture tighten with demanded effort. Do not forget to replace шплинт a pin of fastening of a rod of a pusher to a pedal. Track reliability of fixing of a returnable spring.
2. At replacement of the vacuum amplifier make check/adjustment of the adjusting sizes:
   a. Measure size of a vystupaniye of a pusher over a surface of assembly of the vacuum amplifier interfaced to GTTs (address to an illustration). Write down result of measurement, having designated it as the size "A";
   b. Measure distance from an interfaced surface of a landing flange to GTTs end face (address to an illustration). Write down result of measurement, having designated it as the size "V";
   c. Measure distance from GTTs end face to the bottom a pocket in the piston under landing of a rod of a pusher (address to an illustration). Write down result of measurement, having designated it as the size "S";
   d. For receiving a landing gap of a rod of a pusher subtract the size B from the size C, then from the received result subtract the size A (address to an illustration);
   e. Compare result of calculation to requirements of Specifications, in case of need make the corresponding adjustment of length of a pusher (see further). If the size A appears less depth of a pocket in the GTTs piston (With – In), the rod is necessary for truncating, otherwise – to extend.
3. If the size of a landing gap falls outside the limits an admissible range, weaken the gear nozzle equipped with a notch on the end of a rod and rotation of an adjusting core achieve demanded result (address to an accompanying illustration). Having finished adjustment, strongly tighten a lock-nut and repeat check.
4. Establish into place in GTTs and connect to assembly of the vacuum amplifier a vacuum hose. Track reliability of a tightening of a collar of fastening of a hose on the reception union.
5. Adjust adjusting height and size of a free wheeling of a pedal of a foot brake (see. Section Adjustment of a pedal of a foot brake).
6. Before starting operation of the car make sure of serviceability of functioning of brake system.
