Honda Accord

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

1. Start the engine for a couple of minutes, then muffle. Several times slowly squeeze out a pedal of a foot brake. If at first the pedal course with each squeezing is gradually reduced, however, through three-four musclemen is stabilized, 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 of pressed, kill the engine. If 30 seconds of keeping of the pedal pressed its reserve course later does not change, therefore, tightness of assembly of the vacuum amplifier is not broken.

1. The block of the vacuum amplifier of brakes is not subject to recovery repair and in case of refusal has to be replaced assembled.
2. Remove from the vacuum amplifier assembly of GTTs (see the Section Removal and installation of the main brake cylinder).
3. On models remove the main hydraulic cylinder of coupling from RKPP (see the Head Stsepleniye and power shafts).
4. Disconnect the vacuum hose going to the amplifier from the engine. Try not to damage a hose, removing it from the union on assembly of the amplifier.
5. On 4-cylinder models remove the sensor of temperature of the soaked-up air (IAT) (see the Head Engine management).
6. Under the dashboard find knot of connection of a rod of a pusher of the vacuum amplifier to a pedal of a foot brake.
7. Take the forelock and disconnect a pusher from a pedal.

8. From salon give four nuts of fastening of assembly of the vacuum amplifier to a partition of a motive compartment, remove washers (in case of need use a pocket small lamp).

9. Pass into a motive compartment and remove assembly of the vacuum amplifier of a back partition. After fixing hairpins of the amplifier completely will leave openings in a partition, begin to develop assembly to the right (to the axial line of the car), providing thereby release from a pusher tip partition. Take assembly from a motive compartment.

1. Installation is made as it should be, the return to a dismantle order. Track that all fixture was tightened with the required effort, and pins and forelocks - are replaced.

2. At installation of the new brake amplifier it is necessary to make adjustment of a working gap of a rod of its pusher for what:

a) By means of the manual vacuum pump create depression of 508 mm of mercury in depth on the amplifier., then measure pusher vystupaniye size over the surface of assembly interfaced to GTTs (taking into account laying if that is provided). Write down result of measurement, we will call its "Size A".

b) Measure distance from a basic flange of GTTs to the face surface of the cylinder. Write down result of measurement, having designated it: "Size B".

c) Measure distance from a face surface of GTTs to the bottom of a landing pocket in an end face of its piston. Write down result, having called it: "Size C". d) Subtract the size B from the size C, then, subtract the size A from the received difference. The received result will also determine the size of a required working gap. e) Compare result of calculations to requirements of Specifications. In case of need make the corresponding adjustment.

3. For correction of a working gap of a rod of a pusher weaken a gear lock-nut and rotate the regulator in the relevant party. Having finished adjustment, tighten a lock-nut and again measure a gap. In case of need repeat the procedure.

4. After installation to the place of GTTs pump over the brake system (see the Section Pumping of the Brake System).
