Measurement brake pads the drum-type mechanism

The viewing aperture for the control of a thickness of overlays of the back drum-type brake mechanism is located in a guard of the drum-type brake mechanism in front in a movement direction. At the removed cover are visible brake колодка (1) with the frictional brake overlay pasted on it (2). Also the brake drum (3) is visible.

As active колодка wears out faster back passive, it is necessary to measure a thickness on a lobby колодке.


  1. To lift the car behind.
  2. To remove a plastic cap on an inside of a corresponding wheel in front on a guard of the drum-type brake mechanism.
  3. To light a pocket small lamp in a viewing aperture, to establish a thickness pads.
  4. Deterioration pads is admissible to 2,5 mm of a residual thickness – without a thickness of the carrier. Otherwise they are necessary for changing.
