Condition check, removal and installation of a brake disk

Condition check

 PERFORMANCE ORDER

  1. Weaken bolts of fastening of wheels, поддомкратьте the car and establish it on props. Remove the 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, need for installation of bolts disappears). At check of a disk of the back brake mechanism do not forget to release the parking brake.
  2. Remove a brake support (see. Replacement of blocks of disk brake mechanisms of forward wheels or Replacement of blocks of disk brake mechanisms of back wheels) also 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 wear of brake shoes of a head of rivets of fastening of frictional slips make on a surface of a brake disk deep furrows, - 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 a disk it is necessary to subject more than 0.38 mm to a pro-point. Remember that survey of a disk 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 a tsiferblatny measuring instrument of plunzherny type at 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 to a pro-point.

Originators of the real Management recommend to make a pro-point of disks regardless of their condition for the purpose of removal from working any surfaces of defects. As a last resort it is possible to be limited to disk processing by a fine-grained emery paper.

  1. At a pro-point of 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 the corresponding marking is provided.
  1. Measurement of 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 shoes and an arm of fastening and take him aside, having tied up to a rack.
  1. On models from ABS and two-liter models remove an anchor bracket (see. Removal, regenerative repair and installation of supports of disk brake mechanisms of forward wheels) also 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 shoes (see. Replacement of blocks of disk brake mechanisms of back wheels). Remove a support from the top directing bearing. Take away a support in the parties and tie up it a wire, without disconnecting a brake hose.
  3. Turn out bolts of strengthening of an anchor bracket of 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 as it should be, the return to an order of dismantle of components.

 PERFORMANCE ORDER

  1. Before installation make sure of absoluteness of purity 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 shoes and a support of the brake mechanism (see. Replacement of blocks of disk brake mechanisms of forward wheels).

Back brake mechanisms

Installation is made as it should be, the return to an order of dismantle of components.

 PERFORMANCE ORDER

  1. Before installation make sure of absoluteness of purity 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 it with silicone greasing. Put on a support a finger and establish blocks (see. Replacement of blocks of disk brake mechanisms of back wheels).
