Measurement of a thickness колодок the disk mechanism

Brake Pads the disk mechanisms, having enough big size for forward wheels, maintain to 50 000 km. Despite it, it is not necessary to forget about regular visual check:

 PERFORMANCE ORDER

  1. The minimum thickness колодок should make 2 mm without a bearing plate. Actually bearing plate – that is a metal piece on which the overlay is pasted – has a thickness about 5 mm.
  2. At performance of the fluent control it is enough to light at the removed cap a lamp through an aperture in a wheel and to estimate a thickness of an overlay.
  3. More exact control is spent at the removed wheel: to put a ruler to колодке and to measure, as is shown in the top illustration. Do not forget to examine a frictional overlay on an inside!

Measurement of a thickness колодок the brake mechanism of forward wheels:

1 – an overlay material;
2 – a metal bearing plate.
