HOW TO MEASURE BRAKE DRUMS
When selecting a replacement drum, the manufacturer's name and part number is helpful. If this information is not available, a replacement drum can be selected by comparing dimensions. Below are those dimensions requirements. We must have at least C, D, E, J, K and O to make a selection.
- A. Overall diameter of the drum
- B. Dust Shield recess diameter (if applicable)
- C. Brake Surface Diameter
- D. Overall depth
- E. Brake surface flat
- F. Depth of dust shield recess
- G. Squeeler band thickness
- H. Distance from outside of backface to start of taper
- I. Inside finished diameter
- J. Bolt circle diameter
- K. Pilot diameter
- L. Outside finished diameter
- M. Diameter at taper
- N. Backplate thickness
- O. Bolt holes: number and size
