Wear and fault symptoms
- Wear past the discard, maximum diameter cast or stamped on the drum – for a 16.5 in drum the common discard limit is 0.120 in over nominal, i.e. 16.62 in; once reached the drum is scrap and must not be returned to service
- Heat checking, thermal cracking – fine hairline crazing on the friction surface is normal wear, but any crack running to the open edge or through the wall is an out-of-service condition
- Blue hardened heat spots (martensite) raised proud of the friction surface – causes grabbing, chews linings and cannot be reliably machined out
- Out-of-round, bell-mouthed bore causing brake judder, pulsation and uneven lining contact; typically 0.010-0.015 in runout warrants investigation
- Deep scoring or grooving of the friction surface
- Loss of a factory balance weight, or mixing balanced and unbalanced drums across an axle – causes vibration at road speed and shudder under light braking
Similar symptoms can come from neighbouring components, so inspect and test before replacing the part.
