Special situations require special care
Of course, there are some times
when full-force braking is not the
correct technique. When the road
surface is wet, loose, or rough,
you should brake with care. When
you're leaned over in a corner,
avoid braking. Straighten up
before braking. Better yet, slow
down before entering the corner. ...
Oil pump inspection
Inspect the oil pump in the following procedures:
remove the oil pump. Refer to “oil pump removal and installation” .
Rotate the oil pump by hand and check that it moves
smoothly. If it does not move smoothly, replace the
oil pump assembly.
