Manual Bleeding

Remove the booster vacuum reserve by applying the brakes several times with the ignition "OFF".
1. Fill the master cylinder reservoir with brake fluid and keep reservoir at least one-half full of fluid during the bleeding operation.
2. If the master cylinder is known or suspected to have air in the bore, then it should be bled prior to bleeding at the calipers. Bleed as follows:
a. Disconnect the forward brake pipe connection at the master cylinder.
b. Allow brake fluid to fill the master cylinder until it begins to flow from the forward pipe connector port.
c. Connect the forward brake pipe to the master cylinder and tighten.
d. Depress the brake pedal slowly one time and hold. Loosen the forward brake pipe connection at the master cylinder to purge air from the cylinder. Tighten the connection and then release the brake pedal slowly. Wait 15 seconds. Repeat the sequence, including the 15 second wait, until all air is removed from the bore. Tighten Brake pipe to 15 Nm (11 ft. lbs.).
e. After all air has been removed at the forward connection, bleed the master cylinder at the rear (cowl end) connection in the same manner as the front in Step "D" above.
f. If it is known that the calipers and wheel cylinders do not contain any air, then it may not be necessary to bleed them. Check for hum pedal feel and proper brake pedal travel.
3. Individual calipers are bled only after all air is removed from master cylinder.
a. Place Tool J 21472 over the bleeder valve. Attach a transparent tube over valve and allow tube to hang submerged in brake fluid in a transparent container.
b. Depress the brake pedal slowly one time and hold. Loosen the bleeder valve to purge the air from the cylinder. Tighten bleeder screw and slowly release pedal. Wait 15 seconds. Repeat the sequence, including the 15 second wait until all air is removed. It may be necessary to repeat the sequence several times to remove all the air. Rapid pumping of the brake pedal pushes the master cylinder secondary piston down the bore in a manner that makes it difficult to bleed the system. Tighten Caliper Bleeder Valves to 13 Nm (10 ft. lbs.).
4. Bleeding Sequence
a. Left front
b. Right front
c. Left rear
d. Right rear
5. Check the brake pedal for "sponginess." Repeat entire bleeding procedure if a low brake pedal or pedal "sponginess" is encountered.
