Antiblocking system (ABS)

THE GENERAL DATA

ABS consists of the electronic block of management, the gauges located on wheels, the hydraulic unit, valves and the relay.
Block ABS is located between the main brake cylinder and brakes. Presence ABS does not influence a design of the vacuum amplifier and the main brake cylinder.

Gauges of forward wheels settle down in rotary fists, as shown. They supervise number of turns of wheels of the car through the gear wreaths established on forward drives.
Gauges of back wheels fasten to a beam of the back bridge, as shown.

At occurrence of malfunctions in work ABS it is necessary to address in firm Opel repair truck, having special diagnostic equipment. If signalling device ABS movement can be continued lights up, but the system thus does not work.

REPLACEMENT OF ELEMENTS ABS

REPLACEMENT OF GAUGES OF ANGULAR SPEED OF FORWARD WHEELS

Gauges of forward wheels act in film and established as follows:

Removal

PERFORMANCE ORDER
1. Disconnect a cable of weight from the storage battery.
2. Lift and establish a forward part of the car on supports.
3. Remove a wheel, having provided access possibility to a gauge cable.
4. Take out штекерное connection in a wheel casing from the holder and расстыкуйте it by means of a screw-driver.
5. If is available a little штекерных connections, find out, what of them concerns gauge ABS.
6. Disconnect a cable from fastening.
7. Turn out a face key a bolt of fastening of the gauge and cautiously a screw-driver separate it.

Installation

The gauge in sequence, by return to removal is established.

PERFORMANCE ORDER
1. A fastening bolt tighten the moment of 9 Nanometers.
2. Watch to overwinding a gauge cable. The cable has marks in the form of a white line.
3. At an inhaling of bolts of fastening of a cable pay attention to the various moments of an inhaling.
4. The bolt of fastening of the bottom cable fastens the moment of 27 Nanometers., the top cable the moment of 6 Nanometers.
5. Watch that the gauge of number of turns has not been polluted or damaged.
6. After end of works establish the ignition key into position and check up, that signalling device ABS was switched off.

REPLACEMENT OF GAUGES OF ANGULAR SPEED OF BACK WHEELS

Removal

PERFORMANCE ORDER
1. Disconnect a cable of weight from the storage battery, lift and establish a back part of the car on supports.
2. Find a cable of the gauge and расстыкуйте штекерное connection, disconnect a cable from fastening.
3. Turn out the gauge. The gauge arrangement on a back suspension bracket is shown on an illustration.

Installation

The gauge in sequence, by return to removal is established.

PERFORMANCE ORDER
1. Watch to overwinding a cable at joining. For a correct lining the cable has marks in the form of a white line.
2. Bolts of fastening of the gauge tighten the moment of 22 Nanometers, bolts of fastening of a cable the moment of 27 Nanometers.

INSTRUCTIONS ON GAUGES OF ANGULAR SPEED OF WHEELS

The gauge of angular speed of a wheel consists of the magnetic core and the coil. The principle of action of the gauge is explained by the scheme on an illustration.

The scheme explaining a principle of action of the gauge of angular speed of a wheel


The ledge of a polar tip is surrounded by a magnetic field. In the course of rotation teeths of a gear rotor cross a magnetic field. It leads to distortion weeding that in turn displays an alternating voltage in the gauge coil. Frequency of change of pressure corresponds to number of turns of a wheel. The corresponding information arrives in the management block.
Gear rotors (differently they name pulse rings) have 54 teeth. In front rotors fasten three bolts to an inside of knot a nave / a brake disk. Behind gear rotors напрессованы on drives.

REPLACEMENT OF THE ROTOR OF THE GAUGE OF THE FORWARD WHEEL

PERFORMANCE ORDER
1. Remove a forward nave as it is described in corresponding section.
2. Remove a rotor from the interior of a wheel nave.
3. If the removed rotor is established back, it is necessary to check up surfaces of teeths. They should not have damages.
4. At installation bolts tighten the moment of 18 Nanometers.

REPLACEMENT OF THE ROTOR OF THE GAUGE OF THE BACK WHEEL

PERFORMANCE ORDER
1. Lift and establish a back part of the car on supports.
2. Remove a back drive as it is described in corresponding section.
3. Remove and establish a gear rotor in connection with replacement of the bearing of a drive.
4. The specified work also is described in the Head Brake system
