6.4.8. Removal and rotor installation on a back axis

Fig. 6.88. System ABS components on a back axis (a full drive): 1 – a back brake support; 2 – a wheel nave; 3 – a bolt with a fillet; 4 – a brake disk; 5 – a wheel bolt; 6 – the wheel bearing; 7 – the case of the bearing of a nave of a wheel; 8 – the gauge of frequency of rotation; 9 – a bolt with internal шестигранником; 10 – a power shaft with a rotor; 11 – a bolt, 75 Нм



Removal
Lift the car.
Turn off a wheel.
Turn off a brake support
Suspend a brake support, having fixed it on a body.
Check up a rotor on presence of pollution and damages.
If the rotor has damages it is necessary to remove and replace a nave of a wheel with a rotor.

Installation
Installation is carried out in return sequence.
Again lay a wire of the gauge of frequency of rotation how it lay before removal.
Sealing ring of the gauge of frequency of rotation before installation смажте on perimetre plastic greasing.
Removal and installation of the gauge of frequency of rotation on a back axis (a full drive)

Removal
Loosen the wheel bolts.
Lift the car.
Remove a wheel.
Switch off ignition.

Unscrew screw Torx 3 and take the holder of a cable

Fig. 6.85. The holder of a cable


Unscrew a bolt with шестигранной a head 1 (fig. 6.85).
Unscrew screw Torx 2 and take the holder of a cable
Release a wire of the gauge of frequency of rotation from holders.

Fig. 6.86. Fastening of an overlay of the bottom


Remove a bottom overlay (fig. 6.86).
Take from fastening a seat in a back part of a body.

Fig. 6.87. The holder of a cable and a socket of a wire of the gauge of frequency of rotation


Remove the holder of a cable, disconnect a socket of 1 wire of the gauge of frequency of rotation and to squeeze out a nozzle (from the left and right party an arrangement mirror) (fig. 6.87).

Installation
Installation is carried out in return sequence.
Sealing ring of the gauge of frequency of rotation before installation смажте on perimetre plastic greasing.

Rotor check on a back axis
