Replacement of brake liquid, pumping of brake system

General information

Brake liquid through a ventilating opening of the GTTs tank absorbs moisture. Thereof eventually the boiling point of brake liquid decreases that at considerable load of brakes can lead to formation of steam bubbles in brake lines and reduce efficiency of action of brakes.

It is necessary to replace brake liquid whenever possible in the spring. At car operation in the mountain district, on the roads processed by salt, and also in the conditions of sea air containing salt to replace brake liquid follows more often than it is stipulated in graphics of routine maintenance (see. Undressed the Schedule of routine maintenance).

For replacement of brake liquid the help of the assistant is required, however on HUNDRED this procedure is usually carried out by means of the special device. When pumping brake system the car should be parked on an equal horizontal platform.

Brake liquid is poisonous. Do not suck away her mouth through a hose. Store brake liquid only in capacity to which casual access of children is excluded.

Coal deposits
Symptoms: Availability of soot indicates reenrichment of a fuel and air mix or weak intensity of a spark. Causes ignition admissions, complicates start and results in instability of operation of the engine.
Recommendations: Whether check the air purifier is hammered, whether fuel level in the poplavkovy chamber is not too high, whether the air zaslonka is jammed and whether contacts are not too worn-out. Try to use candles with longer insulator that increases resilience to pollution.
Symptoms: Zamaslivaniye of a candle is called by wear of maslootrazhatelny caps. Oil gets to the combustion chamber through worn-out directing valves or piston rings. Causes ignition admissions, complicates start and results in instability of operation of the engine.
Recommendations: Perform mechanical recovery works and replace candles.
Symptoms: Porous, white insulator, erosion of electrodes and absence of any deposits. Leads to reduction of service life of a candle.
Recommendations: Whether check there corresponds to requirements of Specifications kalilny number of the established candles, whether the corner of an advancing of ignition is correctly exposed, whether too poor fuel and air mix moves, whether there are no leakages of vacuum of the inlet pipeline and whether valves are jammed. Check as level of a cooler and whether the radiator is corked.
Too early ignition
Symptoms: Electrodes are melted off. The insulator has white color, but can be and is polluted owing to ignition or hit admissions in chambers of combustion of extraneous particles. Can lead to an engine exit out of operation.
Recommendations: Check kalilny number of the established candles, a corner of an advancing of ignition, quality of a mix (whether it is not too grown poor), whether the system of cooling is corked and whether the greasing system normally functions.
Electrocarrying-out luster
Symptoms: The insulator has yellowish color and the polished appearance. Speaks about sudden temperature increase in combustion chambers at sharp acceleration. Usual deposits are thus melted off, taking a form of a varnish covering. Leads to ignition admissions at high speeds of movement.
Recommendations: Replace candles (colder, at preservation of a manner of driving).
Short circuit of electrodes
Symptoms: A waste of products of combustion gets to interelectrode space. Firm deposits accumulate, forming a crossing point between electrodes. Leads to ignition refusal in the cylinder.
Recommendations: Remove deposits from interelectrode space.
Normal state of a candle
Symptoms: Gray-brown color and easy wear of electrodes. Kalilnoye number of candles corresponds to type of the engine and its general condition.
Recommendations: At replacement of candles establish candles of the same type.
Symptoms: Soft brownish color of adjournment on one or both electrodes of a candle. A source of their education are applied additives to oil and/or fuel. Excessive accumulation can lead to isolation of electrodes and cause admissions of ignition and unstable operation of the engine at acceleration.
Recommendations: At fast accumulation of deposits change maslootrazhatelny caps that will prevent oil hit in combustion chambers. Try to replace fuel brand.
Symptoms: A rounding off of electrodes with a small congestion of deposits on the working end. Color normal. Leads to difficulty of start of the engine in cold damp weather and to fuel consumption increase.
Recommendations: Change candles on new, the same type.
Symptoms: Insulators can appear chopped off or burst. Also inaccurate equipment of adjustment of a candle gap can lead to damage of an insulator. Can lead to damage of pistons.
Symptoms: After ignition admissions during a long period of adjournment can be loosened at preservation of working temperature in the combustion chamber. At high speeds of adjournment in flakes come off the piston and stick to a hot insulator, causing ignition admissions.
Recommendations: Replace candles or smooth out and establish into place the old.
Mechanical damages
Symptoms: Can be caused by hit of extraneous materials in the chamber of combustion or arise at piston blow about too long candle. Lead to refusal of functioning of the cylinder and to piston damage.
Recommendations: Remove from the engine extraneous particles and/or replace

Replacement of brake liquid and pumping of brake system


  1. Disconnect a negative wire from the storage battery.
  2. Uncover the tank of brake liquid (see an illustration Components of the impellent compartment which is subject to regular service).
  3. Note a felt-tip pen on a tank wall level of brake liquid that then not to change it. Pump out from the tank brake liquid, having left at its bottom a liquid layer in thickness about 10 mm.

Do not delete from the tank all liquid, differently air will get to brake system.

  1. Fill the tank with new brake liquid to a label "MOVE".
  2. After GTTs dismantling and also in case it was devastated, it should be pumped over. For this purpose execute the following actions:
  1. Disconnect from GTTs brake lines.
  2. Ask the assistant to squeeze out a pedal of a brake and to hold it.
  1. Having corked with fingers branch pipes on GTTs, ask the assistant to release a brake pedal.
  1. Repeat procedures b) and c) 3-4 times.
  1. Carefully, not to curtail, open the pumping union. It is recommended in 2 hours prior to the beginning of removal of air to process the union means for rust removal. If the union does not open, on air removal from brake system it is necessary to charge operation to a workshop.
  1. Put on one end of a pure transparent hose the pumping union, and other end insert into a vessel for collecting brake liquid. In capacity it is necessary to pour a little brake liquid and constantly to watch that the end of a hose was shipped in it. Also the capacity should be lifted, at least, on 30 cm over the pumping union to provide pressure and to interfere with intake of air to the pumping union.
  2. Ask the assistant to squeeze out repeatedly a brake pedal while antipressure to pressing of a pedal does not become notable. Squeeze out a pedal and open the pumping union. After the pedal of a brake will rest against a floor, tighten the union. Clean a foot from a pedal. Repeating this process, pump out about 300 ml of old brake liquid before emergence new (she can be learned on light color).
  3. Tighten the pumping union with effort of 8.3 Nanometers and add in the tank new brake liquid.
  4. In the same way pump out old brake liquid from other supports.

Merged brake liquid in any case should be pure and without air vials.

  1. Press a pedal of a brake and check its free wheeling. It should make 1 ± 6 mm.
  2. Fill in brake liquid in the tank to noted before level.
  3. Pump over the actuation mechanism (activator) of brake system. For this purpose execute the following actions:
    • Establish on a jellied mouth of the tank of brake liquid the manual pump with a manometer (the cover of the tank should be removed).
    • Connect to the union of pumping of the activator the transparent flexible hose which other end lower in the capacity filled with brake liquid.
    • Create in the tank pressure of 1 atm (but no more!) by means of the manual pump.
    • Give the union of pumping of the activator, let the air out and tighten the union with effort of 8.3 Nanometers.
  1. On the working engine check tightness of system. For this purpose about 10 times press a brake pedal with effort of 200-300 N (there correspond 20-30 kg). The pedal of a brake should not leave back. Check on leaks all connections of brake lines.
  2. In summary check action of brakes on the road with not heavy traffic of transport. For this purpose it is necessary to make not less than one strong braking, having checked ABS action. A sign of serviceable work of ABS is the pulsation of a pedal of a brake when braking.

The effect of action of ABS is best of all shown on an unpaved road.
