REPAIR OF SIGNAL DEVICES
To remove the alarm, it is enough
disconnect the pipes, wires, and turn-key bolt
holding the nut installed by the bracket.
To disassemble remove the warning device switch 7
(See Fig. 175), take the ball three, then unscrewing the end fitting 8
and the cork 5, push the pistons 2 and 4. When removing the piston from the
housing, be careful not to damage the mirror
cylinder. For this purpose, using a wooden frame.
When disassembling the signaling device replacement O-rings
the piston is required.
Details rinse and dry with compressed air. Make
replacement of damaged parts.
Assembly and installation of signaling devices in reverse
order with the following additional guidance.
A. Mirror of the cylinder, pistons and sealing rings with a thin brush
a layer of fresh brake fluid recommended in Anal. Two.
Two. Each piston is set to the appropriate side, not allowing
passage of the O-ring through the hole under the ball in the
Otherwise, the sealing surface of the ring will be damaged.
Three. Managing grease lubricated ball DT-1.
Control of the warning device is as follows.
A. Connect the camera to one of the hydraulic drive, equipped with a manometer,
the rest of the holes and stop the camera plugs (see ris.184).
Another camera is connected to the environment.
Two. Connect the test lamp in series, the battery
battery and switch the alarm device.
Three. Gradually increasing the pressure, fix the pressure at which
4. Repeat the operation with a second camera (the first camera
communicates with the environment).
WARNING! Tests carried out only fresh brake
fluid recommended in Anal. 2, the same fluid should be
washed pipeline summing the reference pressure.
Five. If the warning lamp lights up when the pressure within the
10,5-21 kg / cm and the brake fluid is not leaking out of the switch,
set the alarm on the car.
The cause of reduced pressure, giving effect to the signal
device - the lack of tightness of seals due to wear of the cylinder mirror
cuff or of poor quality.
The causes of difficult change can be:
- Failure of the switch;
- Scratches on the mirror of the cylinder;
- Swelling of the wrist;
- Poor quality washing the cylinder.
After eliminating the above-mentioned reasons alarm
expose the re-inspection. After setting the alarm
device on the car and the accession hydraulic piping,
bleed the entire hydraulic system, as described in Sec. "Bleeding the brakes
the system. "
