fluid, with no air bubbles, is released from bleeder valve.
Make sure fluid level is maintained in brake fluid res-
ervoir at all times .

bleed valve as follows:
A. Torque caliper bleed valve on front brakes from
54 to 66 in--lb (6.2 to 7.4 N--m) .
B. Torque caliper bleed valve on rear brakes to 38
in--lb (4.3 N--m) .
