Section D - Brake System Bleed Procedure
BEGIN SECTION "D" - Brake System Bleed ProcedureSection "D" contains the brake bleeding procedure for reference when called out in this bulletin.
NOTE:
This section assumes that the brake system has been drained of all old brake fluid.
Manual Bleeding
NOTE:
Be sure that all brake bleed equipment has been drained, cleaned and flushed and refilled with only Suzuki approved part number 990B0-99900-PKG brake fluid.
1. Remove the booster vacuum reserve by applying the brakes several times with the engine OFF until the brake pedal becomes hard.
2. Fill the master cylinder reservoir with Suzuki approved part number 990B0-99900-PKG brake fluid. Keep the master cylinder at least one-half full of fluid during the bleeding operation.
3. Disconnect the front brake line at the master cylinder.
4. Allow the brake fluid to fill the master cylinder internal cavities and begins to flow from the front pipe connector port.
5. Reconnect the brake line to the master cylinder. Tighten the brake line to 16 N.m (12 lb-ft).
6. Slowly push and hold the brake pedal one time.
7. Loosen the front brake line at the master cylinder to purge air from the cylinder.
8. Tighten the brake line to 16 N.m (12 lb-ft), and then release the brake pedal slowly. Wait 15 seconds before proceeding to the next step.
9. Repeat steps 6 through 8, including the 15-second wait, until all the air is removed from the master cylinder bore.
10. After all the air has been removed at the forward connection, bleed the master cylinder at the rear (cowl) connection in the same manner as with the front connection.
11. Remove the right rear bleeder valve dust cover and attach a transparent tube over the wheel bleeder valve. Allow the tube to hang submerged in brake fluid in a transparent container.
NOTE:
Be sure that all brake bleed equipment has been drained, cleaned and flushed and refilled with only Suzuki approved part number 990B0-99900-PKG brake fluid,.
12. Slowly push and hold the brake pedal one time.
13. Loosen the bleeder screw to purge the air from the cylinder.
14. Tighten the bleeder screw to 8 N.m (71 lb-in).
15. Slowly release the brake pedal. Wait 15 seconds before proceeding with the next step.
16. Repeat the sequence steps 12 through 15, until all the air is removed. It may be necessary to repeat the sequence 10 or more times to remove all the air, while never allowing the master cylinder fluid to drop below one-half full of fluid.
17. Repeat steps 11 through 16 for each remaining wheel cylinder; left front, left rear, and right front.
18. Check the brake pedal for sponginess. Repeat the entire bleeding procedure to correct a spongy feeling pedal.
19. Replace the bleeder valve dust covers.
