CLEANING AND INSPECTION.
10-31.
10-32. Use solvent to clean all metal parts,
except the brake shoe assemblies. The shoe rib
and table can be wiped with solvent dampened
cloth. No solvent should get on the lining.
Since solvent may not readily remove brake
fluid residue, use denatured alcohol for this
purpose.
10-33. Examine drums for cracks, heat checks,
and deep grooves. The drums should not be
bell-mouthed or barrel-shaped nor should any
mounting holes be elongated. If any of these
exist, the drums should be replaced. Glaze on
drums, otherwise in good condition, can be
removed by sanding with coarse sandpaper.
FIGURE 10-6.
10-34. The brake shoe linings should be
replaced if worn almost to the table or if the
bonding agent is failing. Do not attempt to
save lining with deep scores or soaked with
either grease or brake fluid.
NOTE: The wheel cylinder should be over-
hauled whenever brake linings are
replaced. Refer to figure 10-9 for parts
arrangement`
10-35. Check all springs and shoe hold-down
parts. Discard any part that is broken, rusted,
twisted, nicked or appears fatigued.
10-37. Check backing plate for distortion.
10-37. Inspect the tapered roller bearings on
the axle for wear and replace if necessary.
NOTE: The brake shoe abuttments should be
