Condition check, removal and installation of a brake disk

Condition check

 PERFORMANCE ORDER

  1. Weaken nuts of fastening of a wheel, поддомкратьте a front of the car and establish it on props. Remove a wheel.
  2. Remove a brake support (The section Removal, major maintenance and installation of a support of the disk brake mechanism). Now there is no need to disconnect from a support a brake hose (see an illustration). Tie up a support to a suspension bracket element by means of a piece of a wire. Do not allow a tension and a perekruchivaniye of a brake hose. On pair of hairpins of fastening of a wheel fixing washers should be already established. If is not present, screw on two of them nuts of fastening of a wheel for disk fixing.
  3. Check a disk surface on existence of scratches, furrows and other damages. Existence of small scratches and superficial furrows is the normal phenomenon for the disk which was in the use does not render appreciable influence on efficiency of braking, however, furrows depth over 0,38 mm demand removal of a disk and carrying out its stanochny processing in the conditions of a car-care center workshop. Do not forget to examine a disk from both parties. If when braking pedal pulsations are felt, it can be a consequence of disk palpation. Check also correctness of adjustment of bearings of wheels.
  4. For check of size of palpation of a disk fix the tsiferblatny indicator of plunzherny type approximately in 13 mm from external edge of a disk and having pressed a plunzher to a disk surface. Null the device and start to rotate a disk. Indications of the indicator should not exceed an admissible limit of palpation. Otherwise the disk is subject to a pro-point in a car-care center workshop.

Originators of this Management recommend to make a disk pro-point in independence of measuring instrument indications (for the purpose of restoration of its surfaces for decrease in pulsations and other undesirable phenomena at the braking, directly connected with a disk condition). As a last resort, surfaces of a disk can be processed simply at least an emery paper, having removed from them polishing traces (making the rotary motions guaranteeing lack of directed traces against an abrasive on a processed surface).


  1. Define size of palpation of a disk by means of a tsiferblatny measuring instrument of plunzherny type - instrument readings should not exceed admissible according to Specifications of a limit of palpation - otherwise the disk is subject to a pro-point or replacement.
  1. By means of rotary motions remove polishing traces from disk surfaces with an emery paper.
  1. The pro-point of a disk should be made taking into account its admissible minimum thickness (usually on an internal surface of a disk there is the corresponding marking). The thickness of a disk can be defined by means of a micrometer. If marking is absent, address to Specifications to this Chapter.
  1. The minimum admissible thickness of a brake disk can be beaten out (or is poured out) on its inside.
  1. Measure thickness of a disk in several points by means of a micrometer.

Removal

 PERFORMANCE ORDER

  1. Remove two wheel nuts, established for disk fixing, then remove a disk from a nave. If the disk is fixed by special, napressovanny washers on hairpins, cut off them diagonal nippers and throw out.
  1. If the disk is fixed on a nave by two special washers, cut off them diagonal nippers and throw out.

Installation

 PERFORMANCE ORDER

  1. Put on a disk the place on hairpins of fastening of a wheel.
  2. Establish support assembly with brake shoes (The section Removal, major maintenance and installation of a support of the disk brake mechanism). Tighten bolts of fastening of a support with demanded effort.
  3. Establish into place a wheel and lower the car on the earth. Tighten nuts of fastening of a wheel with demanded effort.
  4. Several times squeeze out brake for a usadka of blocks on a disk. Pumping of brake system to make there is no need if certainly the brake hose was not disconnected from a support. Before starting operation of the car check serviceability of functioning of brake system.
