Condition check, removal and installation of a brake disk

Condition check

 PERFORMANCE ORDER

  1. Ослабьте bolts of fastening of wheels, поддомкратьте the car also establish it on props. Remove a corresponding wheel, then return pair of wheel bolts for the purpose of fixing of a brake disk (if the screw of fastening of a disk will not turn out yet, necessity for installation of bolts disappears). At check of a disk of the back brake mechanism do not forget to release a lay brake.
  2. Remove a brake support (Replacement колодок disk brake mechanisms of forward wheels or Replacement колодок disk brake mechanisms of back wheels see) and tie up it aside a wire to a suspension bracket element, without disconnecting a brake hose.
  1. Make visual check of a condition of a working surface of a disk. At excessive deterioration brake колодок heads of rivets of fastening of frictional overlays make deep furrows on a surface of a brake disk, - the disk damaged thus is subject to replacement without fail. Easy defects can be eliminated by means of a fine-grained emery paper. For removal of furrows by depth more a disk it is necessary to subject than 0.38 mm проточке. Remember that disk survey should be made from its both parties.
  1. If during braking pulsations of a pedal of a foot brake were noticed, it is necessary to estimate size of lateral palpation of a brake disk. Fix циферблатный a measuring instrument плунжерного type on distance about 12.7 mm from external edge of a disk. Null the device and start to rotate a disk. The result of measurement should not fall outside the limits the admissible range stipulated in Specifications, otherwise it is necessary to give a disk in проточку.

Composers of the present Management recommend to make проточку disks without dependence from their condition for the purpose of removal from working any surfaces of defects. As a last resort it is possible to be limited to processing of a disk by a fine-grained emery paper.

  1. At проточке a disk it is necessary to give particular attention to observance of requirements of Specifications to its minimum admissible thickness. On a face surface of a disk corresponding marks are provided.
  1. Measurement of a thickness of a disk is made by means of a micrometer.

Removal

Forward brake mechanisms

 PERFORMANCE ORDER

  1. Turn out the wheel bolts established at check of a disk.
  1. Remove a forward support with brake колодками and an arm of fastening and take him aside, having tied up to a rack.
  1. On models with ABS and two-litre models remove анкерную скобу (Removal, regenerative repair and installation of supports of disk brake mechanisms of forward wheels see) and liberate a brake hose from a basic arm on a suspension bracket rack.
  1. Turn out the fixing screw and remove a brake disk from a wheel nave.

Back brake mechanisms

 PERFORMANCE ORDER

  1. Turn out the wheel bolts established at check of a disk.
  2. Remove brake колодки (Replacement колодок disk brake mechanisms of back wheels see). Remove a support from the top directing bearing. Take away a support in the parties and tie up its wire, without disconnecting a brake hose.
  3. Turn out strengthening bolts анкерной скобы a support to the bottom lever of a suspension bracket.
  4. Turn out the fixing screw and remove a brake disk from a wheel nave.

Installation

Forward brake mechanisms

Installation is made in an order, the return to an order of dismantle of components.

 PERFORMANCE ORDER

  1. Before installation make sure of absoluteness of cleanliness and dryness of interfaced surfaces of a disk and a nave. Slightly grease a carving part of the screw of fastening of a disk with fixing hermetic.
  2. In summary establish brake колодки and a support of the brake mechanism (Replacement колодок disk brake mechanisms of forward wheels see).

Back brake mechanisms

Installation is made in an order, the return to an order of dismantle of components.

 PERFORMANCE ORDER

  1. Before installation make sure of absoluteness of cleanliness and dryness of interfaced surfaces of a disk and a nave. Slightly grease a carving part of the screw of fastening of a disk with fixing hermetic.
  2. Establish a basic arm of a support and tighten bolts of its fastening with demanded effort. Clear the top finger of a support and grease with its silicone greasing. Put on a support a finger and establish колодки (Replacement колодок disk brake mechanisms of back wheels see).
