This demonstration guide answers one field question about a stretched blade-brake cable or glazed belt. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with blade-brake cable free play at the handle. That reading separates a stretched blade-brake cable or glazed belt from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the blade-brake pad and belt as the primary path. If it is in spec, do not replace the blade-brake pad and belt just to complete a parts list.
Repair the failed system
The usual correction is the blade-brake pad and belt, 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 stretched blade-brake cable or glazed belt.
Stop before you make it worse
Do not wedging the brake to keep the blade spinning. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the blade-brake pad and belt is corrected, convert the visit to a broader diagnosis rather than stacking parts.
