This demonstration guide answers one field question about a brake band that no longer stops the drum. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with brake-band contact and inertia-trip function. That reading separates a brake band that no longer stops the drum from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the brake band as the primary path. If it is in spec, do not replace the brake band just to complete a parts list.
Repair the failed system
The usual correction is the brake band, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about a brake band that no longer stops the drum.
Stop before you make it worse
Do not tying the brake off because it "gets in the way". That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the brake band is corrected, convert the visit to a broader diagnosis rather than stacking parts.
