Inspection
Brake Discs
Dry and inspect them for pitting, burn flaking, significant wear,
glazing, cracking, charring and chips or metal particles imbedded
in lining.
If discs show any of the above conditions, replacement is
required.
Brake Separator Plates and Retaining Plates
Dry plates and check for discoloration. If plate surface is smooth
and even color smear is indicated, plate should be reused. If
severe heat spot discoloration or surface scuffing is indicated,
plate must be replaced.
Brake Return Spring Subassembly

Free length of 1st & reverse brake return spring
“a”: 21.71 mm (0.855 in.)
Free length of 2nd brake return spring

Evidence of extreme heat or burning in the area of clutch may
have caused springs to take heat set and would require their
replacement.

discs.
• Before assembling new discs, soak them in A/T fluid
for at least two hours.
