b. Cleaning.
Cleaning solvent (Fed Spec PD-680) is both toxic and flammable. Avoid
prolonged breathing of vapors. Avoid skin contact. Use only in well-
ventilated area. Keep away from open flame.
Clean all parts with dry cleaning solvent (PD-680) (item 18, Appendix C). Dry parts thoroughly before
inspecting or installing them.
c. Inspection.
(1) Model M127. Inspect for broken or ineffective shoe tension spring (25). Inspect lining (18) for
wear. The minimum thickness of lining before relining cannot be specified exactly and is a matter
of judgement, depending upon usage and amount of time before next regular inspection. Check
fit of brake shoe (20) on anchor pin (12). Check for tolerance of bushing (24) specified in para.
general condition.
