2.
New piston sealing O-Rings should be installed each time the brakes are
disassembled. If re-use is necessary, they should be wiped with a clean cloth
saturated in automotive brake fluid and inspected for damage.
NOTE:
Thorough cleaning is important. Dirt and chips are the greatest single cause of
malfunctions and leaks in hydraulic brake systems.
3.
Check brake linings for deterioration or excessive wear.
4.
Inspect brake cylinder bore for scoring. A scored cylinder will leak or cause rapid
bucket wear. If wear is evident, install a new brake cylinder.
5.
If the anchor bolts on the brake assembly are nicked or gouged, replace with new
bolts.
6.
Inspect wheel brake disc for a minimum thickness of 2mm. If brake disc is below
minimum thickness, install a new part. For directional brake discs, refer to Figure 16
for installation details.
