ing, charring and chips or metal particles imbedded in lining. If discs

D Before assembling new discs, soak them in A/T fluid for at
least two hours.
Clutch and Brake Plates and Flanges
Dry plates and check for discoloration. If plate surface is smooth
and even color smear is indicated, the plate should be reused. If se-
vere heat spot discoloration or surface scuffing is indicated, the
plate must be replaced.
