Drum Identification - The easiest way to identify brake drums is to match the casting numbers. This is normally either inside the drum or on the outer edge and identifies the drum type. The same drum is likely to have several wheel fitments so you then must check your wheel PCD and the hub cap diameter. A good final check is to compare the internal diameters.
Brakes are a safety system and it is essential you check the new part is the same as the old one before fitting.
