Safety & Care of Discs

Cast iron brake discs should not normally be operated at bulk temperatures in excess of 6l0°C and above rotational speeds of 3000 revolutions per minute.

Discs must be regularly and frequently inspected for excessive heat crazing and cracking.

Discs with cracks emanating from mounting holes / slots, inside diameter, scallops, or outside diameter should be changed immediately.

After heavy and prolonged use some surface crazing will often be evident. If this turns into distinct surface cracks which are radiating towards the inside or outside diameter the disc should be changed.
