REMARKS

WARNIN G

Drycleaning solvent PD-680 is both toxic and flammable. Avoid prolonged breathing of

vapors and avoid skin contact. Use only in well-ventilated area, and keep away from

open flame. Injury to personnel could occur.

Brake linings contain asbestos fibers. Protective mask must be worn while performing

maintenance on brake linings. Failure to do so could result in serious injury to

personnel.

Worn brake linings could result in injury or death to personnel. When brake linings are

worn to within 0.0625-inch (1.59 mm) of rivets, they must be replaced.

NOT E

There are four brakeshoes on the semitrailer. This procedure is for one. Repeat for

the others.
