Special tools and workshop equipment required
t  Wiring loom repair kit, e.g. Skoda Car Tool Kit Škoda, Order No.: -S 504 500 V-
t  Solid lubricant paste-G 000 650-
Remove and install wheel speed sensor (disc brake - front-wheel drive)
Removing
–  Raise vehicle.
   
–  Separate plug connection -1- wheel speed sensor cable/wheel speed sensor.
–  Release screw -2-.
–  Take the wheel speed sensor -G44- / -G46- out of the axle stud.

–  Clean the inner surface of the hole before inserting the wheel speed sensor and coat with a solid lubricant paste -G 000 650-.
  N45-0118
–  Insert the wheel speed sensor in the bore of the axle stud and tighten the screw -2- to 8 Nm.
–  Connect plug connection -1- wheel speed sensor cable/wheel speed sensor.
Remove and install wheel speed sensor (drum brake)
Removing and installing the wheel speed sensor occurs in the same way as for the disc brake version - front-wheel drive → Chapter.
1 - Plug connection wheel speed sensor cable/wheel speed sensor
2 - Screw for fixing the wheel speed sensor.
Check pulse rotor or remove and install (disc brake and drum brake)
  Note
t  The figures show only the rear axle with disc brake.
t  Parts of the ABS system on the rear axle with drum brake are analogous to the version with disc brake.
–  Raise vehicle.
–  Remove wheel.
Vehicles with disc brakes:
  N45-0117
–  Unscrew screws -A-, remove brake caliper and tie up laterally with wire or anything similar.
Brake lines must not be exposed to tension.
Vehicles with drum brakes:
–  Remove the brake drum → Chapter.
All vehicles:
  S42-0062
–  Check pulse rotor by turning the brake disc or the wheel hub
1 - for contamination
2 - Wheel speed sensor -G44- / -G46-
3 - Wheel speed sensor screw
-Arrow- Plug connection of wheel speed sensor - wheel speed sensor cable
–  If the chunking of the pulse rotor is blocked by dirt, the pulse rotor must be cleaned.
–  If the pulse rotor is damaged, the wheel hub and the pulse rotor must be replaced.
Vehicles with drum brakes → Axles, steering; Rep. gr.42.
Vehicles with disc brakes → Axles, steering; Rep. gr.42.
–  Attach the wheel.
–  Lower the vehicle.
Remove and install the rear wheel speed sensor cables
  Note
t  It is prohibited to repair shielded leads of the ABS system.
t  Before disconnecting the battery determine the code of radio sets fitted with anti-theft coding.
t  After connecting the battery, perform the following:
–  on vehicles with radio encoding, carry out the coding,
–  re-set clock,
–  initialise power windows on vehicles fitted with power windows → BookletOctavia

t  Parts of the ABS system on the rear axle with drum brake are analogous to the version with disc brake.
–  Disconnect battery.
–  Raise vehicle.
–  Remove wheel.

  N97-0016
–  Clip in wheel speed sensor cable -arrows-.
  Note
When assembling the wheel speed sensor make sure the wheel speed sensor cable is not twisted when installed in the wheelhouse.
–  Separate the 2-pin plug, if present, on the new wheel speed sensor cable using the wire stripper, strip as of 15 mm from the cable extremity and turn the stripped cable halfway.
–  Instead of the welding spot, the wheel speed sensor cable must be connected using a suitable crimp connector from the wiring loom repair kit.
–  Install luggage compartment side trim panel → Body Work; Rep. gr.70.
–  Attach the wheel.
–  Connect battery → Electrical System; Rep. gr.27.
