6.4.8. Removal and installation of a rotor on a back axis

Fig. 6.88. ABS system components on a back axis (four-wheel drive): 1 – back brake support; 2 – wheel nave; 3 – a bolt with a fillet; 4 – brake disk; 5 – wheel bolt; 6 – wheel bearing; 7 – case of the wheel bearing; 8 – rotation frequency sensor; 9 – a bolt with an internal hexagon; 10 – a power shaft with a rotor; 11 – bolt, 75 N · m



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

Installation
Installation is carried out in the return sequence.
Again lay a rotation frequency sensor wire how it lay before removal.
Grease a sealing ring of the sensor of frequency of rotation before installation on perimeter with plastic lubricant.
Removal and installation of the sensor of frequency of rotation on a back axis (four-wheel drive)

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