The headlight hydraulic corrector consists of a master cylinder mounted on the instrument panel, slave cylinders mounted on the headlights, and connecting tubes. Cylinders and tubes are filled with a special fluid that does not freeze at low temperatures. The design of the hydraulic corrector is non-separable, and in case of damage it is replaced as a whole, complete with cylinders and tubes.
If the angle of inclination of the headlights has increased and the adjusting screws on the headlight fail to bring it back to normal, then check for fluid leaks from the cylinders or tubes of the hydraulic corrector. Remove the slave cylinders from the headlights and check the stroke of the rods, which should be (7±0,5) mm.
To replace a damaged hydraulic corrector, disconnect the tube clamps from the wire clamps. Remove the handle from the master cylinder and unscrew the nut securing it to the instrument panel. Disconnect the slave cylinders from the headlights and push them with the seal into the vehicle interior. Install the new hydraulic corrector in the reverse order of removal.
