27. Remove five
1 ⁄
2
-13 nuts and lock washers
behind dust shield.
28. Pull backing plate assembly far enough out on
spindle, away from dust cover , to allow access to
nuts on the two shoe hold down bolts .
Note: If you prefer to perform a bench repair on the
brakes, and wish to avoid opening the hydraulic
system, remove the bolts holding the wheel cylin-
der. This allows complete removal of the backing
plate.
29. Remove hold down cotter pins and castellated
nuts .
30. Remove spring washers .
Note the orientation of these washers. They must be
re-installed in the same relationship to each other,
and to the nut/washer, in order to provide correct
spring force.
31. Remove large flat washer .
32. Remove hold down bolts and brake shoes .
33. Inspect brake shoes. Check that web is flat and at a
right angle to table. Check welds for cracks. Check
operating holes for wear and peening. If any defect
or damage is noted, replace shoes regardless of lin-
ing status.
34. Replace any shoes contaminated with oil.
35. If replacing one shoe set due to normal wear, Great
Plains recommends replacing all shoes on the
machine.
Braking Malfunction Hazard:
Always replace brake shoes in pairs - both shoes on the same
drum. Replacing only one shoe of each set can lead to reduced
braking performance, or loss of braking, with the risk of an
accident resulting in death, serious injury or property damage.
Note: Cannot Re-Line:
Original and replacement brake shoes supplied or
recommended by Great Plains have bonded lin-
ings. They cannot be re-lined. Replace entire
shoes, in pairs.
