12.5. Deterioration measurement колодок the disk brake mechanism

For correct check of a condition of overlays it is necessary to remove a corresponding wheel. Take a plate in the thickness in 1,5 mm and insert it between a disk and the holder of an overlay. If an overlay of the same thickness, as a plate it is necessary to replace all segments on the corresponding bridge.

Pedal of a brake and overlay brake колодок

By means of this check basically it is impossible to establish a deterioration of overlays. In free supports of a brake drive there is enough elasticity of linings of the brake piston and standard palpation качания (0,05 mm) a brake disk that – after each process of braking – automatically to wring out an overlay from a brake disk. At not pressed pedal a substantive provision of overlays concerning a brake disk and a course of a pedal of a brake remain constants – at least until overlays will not be completely worn out.

Check up a hand at the working engine idling of a pedal of a brake, it should make, as a last resort, third of a full speed.

If the pedal course has considerably increased, it occurs from worn out – or probably clamped in supports – brake overlays, at times "is clamped" as well a support of the disk brake mechanism. Certainly, it is possible to reduce a course of a pedal after repeated pumping that in system "has appeared" less air: however open the reason, eliminate malfunction and pump over brake system as it is described more low.
