brake fluid out of the bleeder screw.
9. Close the bleeder screw.
10. Repeat steps 6 thru 9 until a stream of air-free fluid is
coming out of the bleeder screw.
NOTE: To eliminate the necessityof having to close the bleed-
er screw after eachtime the parking brake knob is pulled out,
the following alternate bleeding procedure may be used.
Attach a bleeder hoseto the bleeder screw. Immersethe other
end of the bleeder hose in a clean jar partially filled with
fresh brake fluid. The parking brake knob may be pulled out
and pushed in without the necessity of closing the bleeder
screw until air-free fluid is coming out of the hose in the jar.
When air-free fluid comes out of the hose, close the bleeder
screw and remove the hose.
11. Open one of the bleeder screws(II lust. 19) on top of the
brake caliper which is connected to the actuator for which
the displacement cylinder was just bled.
