10:18. Check, removal and installation of brake disks

Check

Measurement of size of a side beating of a brake disk (on the example of the brake mechanism of a forward wheel)


 PERFORMANCE ORDER

  1. Estimate the size of a side play of the wheel bearing, in case of need make the corresponding adjustment (see the Head the Transmission line).
  2. Remove wheels and visually estimate a condition of brake disks. At identification of deep furrows disks should be pierced within admissible values, or to replace (see below).

Disks are subject to replacement also in case thickness any of them goes beyond the lower bound of admissible range (see Specifications).

  1. Fix the dial DTI measuring instrument on stupichny assembly, having pressed its plunger to a side surface of a disk.
  2. Nullify the measuring instrument and, rotating a disk determine the size of its side beating.
  3. Compare result of measurement to requirements of Specifications, in case of need replace disks (see below).

Removal and installation

Brake disks have to change a set at the same time for both wheels of one axis!
